PENDAHULUANPerkembangan ekonomi Indonesia dewasa ini menunjukkan semakin terintegrasi dengan perekonomian dunia. Hal ini merupakan konsekuensi dari dianutnya sistem perekonomian terbuka yang dalam aktivitasnya selalu berhubungan dan tidak lepas dari fenomena hubungan internasional. Adanya keterbukaan perekonomian ini memiliki dampak pada perkembangan neraca pembayaran suatu negara yang meliputi arus perdagangan dan lalu lintas modal(prenominal) verb verb auxiliary auxiliary verb verb(pre nominative) terhadap luar negeri suatu negara.salaat satu bentuk aliran modal yang masuk ke dalam negeri yaitu dapat berupa devisa yang berasal dari perdagangan internasional yang dilakukan oleh negara tersebut. Mening katnya ekspor suatu negara akan membawa keuntungan yaitu kenaikan pendapatan, kenaikan devisa, transfer modal dan makin banyaknya kesempatan kerja. Demikian pula meningkatnya impor suatu negara akan memberikan lebih banyak alternatif barang-barang yang dapat dikonsumsi dan terpenuhinya kebutuhan bahan-bahan baku penolong serta barang modal untuk kebutuhan industri di negara-negara tersebut dan transfer teknologi.Perdagangan internasional akan terjadi pada suatu perbandingan harga tertentu yaitu antara harga ekspor dan harga impor yang sering disebut nilai tukar perdagangan ( toll of craft, add). Nilai tukar perdagangan besar sekali pengaruhnya terhadap kesejahteraan suatu bangsa dan juga sebagai pengukur posisi perdagangan luar negeri suatu bangsa. TOT yang disimbolkan dengan N dihitung sebagai perbandingan antara indeks harga ekspor (Px) dengan indeks harga impor (Pm) atau N = Px/Pm (Nopirin 1992 71). Kenaikan N menunjukkan perbaikan di dalam basis of Trade. Perbaikan hurt of look at ini dapat timbul sebagai akibat nilai perubahan harga ekspor yang lebih besar realatif terhadap harga impor.Perbaikan toll of mint akan meningkatkan pendapatan negara tersebut dari perdagangan demikian sebaliknya. Selain mempengaruhi pendapatan negara, pergerakan TOT juga mempengaruhi nilai tukar riil, (Mankiw, 2000 195). Upaya untuk mengatasi pengaruh memburuknya basis of condescension terhadap nilai tukar ini dapat menggunakan cadangan devisa (external reserves) yang dimiliki negara yang bersangkutan. Hal ini dibuktikan oleh penelitian Aizenman and Crichton (2006), menyebutkan bahwa negara-negara yang mengekspor barangbarang sumberdaya alam memiliki volatilitas scathe of work yang 3 kali lebih volatil dibandingkan negara-negara yang mengekspor barang manufaktur. Selain besaran pergerakan TOT, volatilitas ini juga mempengaruhi nilai tukar riil suatu negaraPada dasarnya international reserves berfungsi sebagai buffer stock untuk berjaga-jaga guna menghadapi ketidakpast ian keadaan yang akan entropyng. Sehingga, apabila terjadi depresiasi nilai tukar riil akibat memburuknya cost of trade maka disitulah international reserves berfungsi sebagai penstabil. Perbaikan terms of trade akan meningkatkan aliran modal masuk sehingga akan kembali mendorong apresiasi nilai tukar riil.Seperti halnya penelitian yang dilakukan oleh Rajan dan Siregar (2004), diperoleh bahwa reserves merupakan kunci utama dari suatu negara untuk dapat menghindari krisis ekonomi dan keuangan. Terutama bagi negara-negara dengan perekonomian yang terbuka dimana aliran modal internasional adalah volatil atau rentan terhadap terjadinya shock yang merambat dari negara lain (contagion effect). Bahwa dengan melihat pengalaman krisis yang terjadi pada tahun 1997, negara yang memiliki reserves yang besar dapat menghindari contagion effect dari krisis dengan lebih baik dibandingkan dengan negara yang memiliki reserves yang kecil.Upaya untuk mengatasi gejolak nilai tukar akibat terms of tr ade shock selain dengan international reserves juga dapat diatasi dengan mengukur financial deepening (kedalaman sektor keuangan) suatu negara. monetary deepening diukur melalui rasio M2 dibagi bring in domestic product (Gross Domestic Product). Penggunaan rasio ini dikarenakan merupakan rasio blench umum yang digunakan untuk mengukur perkembangan sektor keuangan suatu negara. Hasil rasio ini akan menunjukkan rasio penggunaan M2 untuk menghasilkan setiap GDP. Semakin kecil dalam rasio tersebut menunjukkan semakin dangkal sektor keuangan suatu negara dan semakin besar rasio tersebut menunjukkan sektor keuangan negara tersebut semakin dalam.Suatu negara dengan rasio financial deepening yang besar cederung mengurangi peran international reserves sebagai penstabil nilai tukar riil. Hal ini dikarenakan negara dengan rasio financial deepening yang besar dapat dikatakan telah memiliki pertumbuhan ekonomi yang sudah baik sehingga negara tersebut dapat mengatasi gejolak nilai tukar akibat terms of trade shock dengan penyesuaian otomatis melalui mekanisme pasar, Aizenman dan Crichton (2006).Karakteristik Indonesia sebagai small open economy yang menganut sistem devisa bebas dan sistem nilai tukar mengambang (free floating) menyebabkan pergerakan nilai tukar di pasar rentan oleh pengaruh faktor ekonomi dan non-ekonomi. Untuk mengurangi gejolak nilai tukar yang berlebihan maka pelaksanaan intervensi menjadi sangat penting terutama untuk menjaga stabilitas nilai tukar pada saat tertentu yang benar-benar dibutuhkan agar dapat memberikan kepastian bagi dunia usaha. salaah satu bentuk intervensi itu adalah dengan menggunakan international reserves dan ini sejalan dengan argumentasi Aizenman,dkk (2004) bahwa suatu negara yang menerapkan sistem nilai tukar mengambang bebas akan cenderung mengurangi permintaan international reserves-nya.Di Indonesia, pious platitude Indonesia sejauh ini berupaya untuk mengoptimalkan berbagai fasilitas atau insentif agar semakin banyak ekspo rtir yang bersedia menyerahkan devisa hasil ekspornya ke Bank Indonesia (Goeltom dan Zulverdi, 1998). Bahkan dalam masa krisis pasar modal global 2008 ini, Bank Indonesia mewajibkan pengguna valas untuk melaporkan peruntukannya jika melebihi US$10.000 per bulan.Permasalahan mendasar yang diangkat dalam penelitian ini diantaranya 1) Bagaimanakah pengaruh international reserves dalam perannya sebagai penstabil nilai tukar riil akibat terms of trade shock. 2) Bagaimanakah pengaruh financial deepening dalam perannya sebagai penstabil nilai tukar riil akibat terms of trade shock. Kedua permasalahan tersebut akan dibahas bagaimanakah pengaruhnya di keseluruhan obyek penelitian dan juga secara spesifik setiap Negara untuk memperoleh perbandingan antar Negara, khususnya antara Indonesia dengan Negara-negara mitra dagang utama (Amerika serikat, Jepang, Singapura, Korea Selatan dan Hongkong).II. TEORIII.1. international reservesThe subscribe to of a cardinal marge for international reserv es is similar to an case-by-cases swear to hold cash balances (currency and checkable deposits) (Carbaugh, 2004 513). Dari pernyataan tersebut dapat disimpulkan bahwa kebutuhan international reserves bagi suatu negara mempunyai tujuan dan manfaat seperti halnya manfaat kekayaan bagi suatu individu. motivation kepemilikan international reserves dapat disamakan dengan subject seseorang untuk memegang uang yaitu untuk motif transaksi, motif berjaga-jaga dan motif spekulasi. need transaksi antara lain untuk membiayai transaksi impor yang dilakukan oleh pemerintah dalam rangka mendukung proses pembangunan, motif berjaga-jaga berkaitan dengan mengelola nilai tukar, serta motif yang ketiga adalah untuk lebih memenuhi kebutuhan diversifikasi kekayaan (memperoleh return dari kegiatan investasi dengan international reserves (Gandhi, 2006 1).Jhingan (2001) menyatakan bahwa outside(a) liquid (generally used as a synonym for international reserves) is defined as the aggregate stock of inte rnally acceptable summations held by the central lingo to settle a deficit in a countrys balance of payments. world(prenominal) reserves merupakan asset dari bank sentral yang dipergunakan untuk mengatasi ketidakseimbangan neraca pembayaran. Definisi tersebut senada dengan konsep International militia and Foreign capital Lliquidity (IRFCL) yang dikeluarkan oleh IMF bahwa international reserves didefinisikan sebagai seluruh aktiva luar negeri yang dikuasai oleh otoritas moneter dan dapat digunakan setiap waktu guna membiayai ketidakseimbangan neraca pembayaran atau dalam rangka stabilitas moneter 3.3 Guidelines for International militia and Foreign gold Liquidity, IMF, 2001.Sedangkan menurut Salvatore (1996 513), bahwa international reserves merupakan asset-asset likuid dan berharga tinggi yang dimiliki suatu negara yang nilainya diakui atau diterima oleh masyarakat internasional dan dapat dipakai sebagai alat-alat pembayaran yang sah bagi pemerintah atau negara yang merupaka n pemiliknya dalam mengadakan transaksi-transaksi atau pembayaran internasional. Selain untuk tujuan stabilisasi nilai tukar, terkait dengan neraca pembayaran international reserves dapat digunakan untuk membiayai impor dan membayar kewajiban luar negeri. Besar kecilnya akumulasi international reserves suatu negara biasanya ditentukan oleh kegiatan perdagangan (ekspor dan impor) serta arus modal negara tersebut.Kecukupan international reserves ditentukan oleh besarnya kebutuhan impor dan sistem nilai tukar yang digunakan. Dalam sistem nilai tukar yang mengambang bebas, fungsi international reserves adalah untuk menjaga stabilitas nilai tukar hanya terbatas pada tindakan untuk mengurangi fluktuasi nilai tukar yang terlalu tajam. Oleh karena itu, international reserves yang dibutuhkan tidak perlu sebesar international reserves yang dibutuhkan apabila negara tersebut mengadopsi sistem nilai tukar tetap. Wujud utama dari international reserves adalah emas, hard currencies yang pada umum nya dalam bentuk empat jenis mata uang utama yang dianggap discolor berpengaruh di dunia, yaitu US dollar, Euro, Poundsterling dan pine serta surat-surat berharga terbitan IMF yang biasa disebut sebagai Special Drawing Rights (SDRs). Penjelasan lebih rinci mengenai komponen international reserves sebagaimana dijelaskan oleh Gandhi (2006 4).Berkaitan dengan sifat dari rezim nilai tukar (sistem nilai tukar tetap, mengambang dan mengambang terkendali) di negara yang menganut sistem nilai tukar tetap pada umumnya memerlukan international reserves yang besar untuk mempertahankan nilai tukar pada take aim yang ditetapkan. Hal ini dikarenakan oleh ketakutan negara itu akan ketidakpastian dalam sistem nilai tukar mengambang bebas yang diterapkannya. Sehingga, sebagai upaya untuk berjagajaga dalam menghadapi fluktuasi nilai tukarnya otoritas moneter negara tersebut membutuhkan international reserves dalam jumlah yang dianggap memadai guna stabilisasi nilai tukar.Pada sistem nilai tukar me ngambang, terjadinya pergerakan nilai tukar dapat diatasi sendiri oleh mekanisme pasar, sehingga jumlah international reserves yang dibutuhkan tidak sebanyak yang dibutuhkan oleh suatu negara dengan sistem nilai tukar tetap yang rigid. Menurut Carbaugh (2004 516), tujuan utama dari international reserves adalah untuk memfasilitasi pemerintah dalam melakukan intervensi pasar sebagai upaya untuk menstabilkan nilai tukar. Sehingga, suatu negara dengan aktivitas stabilisasi yang aktif memerlukan jumlah international reserves yang besar pula.Keterbukaan perekonomian suatu negara tercermin dengan semakin besarnya transaksi perdagangan dan aliran modal antar negara. Semakin terbuka perekonomian suatu negara kebutuhan international reserves-nya cenderung semakin besar guna membiayai transaksi perdagangan. Parameter yang biasa dipakai untuk mengukur kecukupan international reserves sehubungan dengan transaksi perdagangan antar negara adalah peripheral tendency to import. Semakin besar angk a propensity tersebut menunjukkan semakin besarnya kebutuhan international reserves yang harus dimiliki dan semakin kecil angka propensity tersebut menunjukkan semakin kecilnya kebutuhan international reserves yang harus dimiliki (Gandhi, 2006 11). Dengan tersedianya international reserves yang mencukupi maka apabila suatu negara mengahadapi kondisi terms of trade yang buruk yang kemudian akan berpengaruh pada nilai tukar riilnya maka international reserves dapat berperan sebagai absorber.II.2. Nilai Tukar Perdagangan (Terms of Trade)Terdapat beberapa konsep tentang TOT. Konsep pertama merupakan konsep yang colour umum digunakan, yaitu net calling terms of trade atau juga dapat disebut trade good terms of trade. fire barter terms of trade adalah perbandingan antara indeks harga ekspor dengan indeks harga impor. Kenaikan ekspor menunjukkan perbaikan di dalam nilai tukar perdagangan, artinya untuk sejumlah tertentu ekspor dapat diperoleh jumlah impor yang lebih banyak dengan melal ui hubungan harga (Nopirin, 1995 71).Forumulasinya dapat dituliskan dengan rumus sebagai berikut(III.1)Dimana, Px adalah Indeks harga ekspor Pm adalah Indeks harga impor dan 100 adalah Indeks tahun dasar. Bila N 100 atau terjadi kenaikan net barter terms of trade maka berarti terjadi perkembangan perdagangan luar negeri yang positif karena dengan nilai ekspor tertentu diperoleh nilai impor yang lebih besar (Hady, 200177).Konsep kedua adalah gross barter terms of trade, merupakan perbandingan antara indeks stack impor dengan indeks volume ekspor. Konsep ini menjadi tidak penting karena kurang memberikan gambaran tentang perubahan harga. Oleh karena itu, apabila konsep terms of trade tanpa diberi penjelasan apa-apa maka yang dimaksud adalah konsep net barter terms of trade.Konsep ketiga adalah income terms of trade yang dapat dituliskan dengan rumus sebagai berikut (III.2)Dimana N adalah net barter terms of trade Px adalah Indeks harga ekspor Pm adalah Indeks harga impor dan Qx adala h Indeks kuantitas ekspor.Berdasarkan konsep ini, kenaikan income terms of trade menunjukkan bahwa suatu negara dapat memperoleh jumlah impor yang lebih besar dengan dasar kenaikan nilai ekspornya. Bagi negara-negara yang sedang berkembang, selain variabel harga juga sangat penting untuk menilai terms of trade ini dengan mempertimbangkan volume ekspornya karena kenaikan harga ekspor yang tinggi mungkin diimbangi dengan turunnya volume ekspor.Perbaikan TOT dapat timbul sebagai akibat (1) harga ekspor naik sedang harga impor tetap (2) harga ekspor tetap sedang harga impor turun (3) harga ekspor naik dengan proporsi yang lebih besar daripada naiknya harga impor (4) harga ekspor turun dengan proporsi yang lebih kecil daripada turunnya harga impor.Mekanisme bagaimana TOT dapat berpengaruh pada nilai tukar riil adalah dapat dilihat dari sebuah mekanisme sederhana yaitu perbaikan TOT akan meningkatkan aliran modal masuk yang berasal dari perdagangan yang selanjutnya dapat mengapresiasi nil ai tukar riil dan sebaliknya. Memburuknya TOT akan mengakibatkan permintaan valuta asing meningkat sehingga akan mendepresiasi nilai tukar riil.Terkait dengan jenis produksi yang diperdagangkan, maka secara umum nilai tukar perdagangan komoditi (commodity terms of trade atau net barter terms of trade) negaranegara berkembang cenderung mengalami kemerosotan dari waktu ke waktu. salat satu penyebab utamanya adalah sebagian besar atau bahkan semua kenaikan produktivitas yang terjadi di negara-negara maju dialirkan ke para pekerjanya dalam bentuk upah dan pendapatan yang lebih tinggi, sedangkan sebagian besar atau seluruh kenaikan produktivitas yang berlangsung di negara-negara berkembang diwujudkan sebagai harga-harga produk yang lebih murah (Salvatore, 1996 431).II.3. Nilai Tukar Riil (Real throw Rate) dan Pasar ValasSetiap negara memiliki sebuah mata uang yang menunjukkan harga-harga barang dan jasa. Pengertian nilai tukar valuta asing adalah Exchange rate is the price of one nati ons bills in terms of another nations bills. The nominal exchange rate is usually called the exchange rate. Menurut definisi tersebut nilai tukar diartikan sebagai harga suatu mata uang terhadap mata uang negara lain. Nilai tukar nominal biasa disebut nilai tukar (exchange rate) (Pugel, 2004). Menurut Mankiw, nilai tukar nominal adalah harga relatif dimana seseorang dapat memperdagangkan mata uang suatu negara dengan mata uang lainnya (Mankiw, 2000 200).Dengan menggunakan suatu indeks harga untuk Indonesia (P), sebuah indeks harga untuk harga-harga di luar negeri (P*) dan nilai tukar nominal antara rupiah dengan mata uang asing (e), akan dapat diukur nilai tukar riil keseluruhan antara Indonesia dengan negara-negara lain sebagai berikut Nilai Tukar Riil = (e x P) / P* (III.3)Terdapat paling tidak 3 faktor utama yang mempengaruhi permintaan valuta asing. Pertama, faktor pembayaran impor. Semakin tinggi impor barang dan jasa, maka semakin besar permintaan terhadap valuta asing sehin gga nilai tukar akan cenderung melemah. Kedua, faktor aliran modal keluar (capital outflow). Semakin besar aliran modal keluar, maka semakin besar permintaan valuta asing dan pada kelanjutannya akan memperlemah nilai tukar. Aliran modal keluar meliputi pembayaran hutang penduduk Indonesia (baik swasta dan pemerintah) kepada pihak asing dan penempatan dana penduduk Indonesia ke luar negeri. Ketiga, kegiatan spekulasi. Semakin banyak kegiatan spekulasi valuta asing yang dilakukan oleh spekulan, maka semakin besar permintaan terhadap valuta asing sehingga memperlemah nilai tukar mata uang lokal terhadap mata uang asing.Sementara itu, penawaran valuta asing dipengaruhi oleh dua faktor utama. Pertama, faktor penerimaan hasil ekspor. Semakin besar volume penerimaan ekspor barang dan jasa, maka semakin besar jumlah valuta asing yang dimiliki oleh suatu negara dan pada lanjutannya nilai tukar terhadap mata uang asing cenderung menguat atau apresiasi. Kedua, faktor aliran modal masuk (capita l inflow). Semakin besar aliran modal masuk, maka nilai tukar akan cenderung semakin menguat. Aliran modal masuk tersebut dapat berupa penerimaan hutang luar negeri, penempatan dana jangka pendek oleh pihak asing (portofolio investment) dan investasi langsung pihak asing (foreign prepare investment) (Simorangkir dan Suseno, 2004 6).II.4. Financial intensifyUkuran dari perkembangan intermediasi keuangan biasanya digunakan pengukuran indikator melalui kuantitas, kualitas, dan efisiensi dari jasa intermediasi keuangan (Calderon, 20025). Terdapat beberapa indikator untuk mengetahui seberapa besar tingkat perkembangan sektor keuangan salah satu diantaranya adalah rasio antara aset keuangan dalam negeri terhadap GDP (Muklis, 2005 2).Menurut superpower dan Levine (1993), Financial deepening means an increase in the money supply of financial assets in the economy, it is important to larn some measures of the widest range of financial assets, including money. Selain itu, King dan Levine m erancang 4 ukuran dalam perhitungan perkembangan sektor keuangan. Pertama, ukuran dari kedalaman sektor keuangan adalah rasio dari kewajiban lancar (liquid liabilities) dari sistem keuangan terhadap GDP. Kewajiban lancar dalam hal ini adalah M3, namun apabila M3 tidak bisa didapatkan maka digunakan M2. Hal ini sejalan dengan IMF dalam entropybase International Financial Statistic dan juga Slangor (199111). Kedua, adalah rasio dari deposit money bank domestic asset dibagi dengan deposit money bank domestic asset ditambah dengan central bank domestic asset yang menggambarkan institusi keuangan yang lebih spesifik. Ketiga, rasio kredit dari sektor swasta non keuangan dibagi dengan total kredit domestik. Keempat, adalah rasio kredit sektor swasta non-keuangan dibagi dengan GDP. Dua yang terakhir ini menggambarkan ukuran kuangan sektor dan tingkat pinjaman publik (King dan Levine, 1993 4).Penggunaan rasio M2 terhadap GDP sebagai indikator financial deepening juga dibenarkan oleh King da n Levine, (1993 5). Semakin kecil rasio tersebut maka semakin dangkal sektor keuangan suatu negara. Suatu negara dikatakan memiliki sektor keuangan yang dalam apabila M2 20% dari GDP dan dangkal apabila M2 III. METODOLOGIJenis entropy yang digunakan dalam penelitian ini adalah entropy sekunder dan merupakan info circuit card, mencakup periode 2000Q1 2006Q4 dan 6 negara yakni Indonesia dan 5 negara mitra dagang utamanya yaitu Amerika Serikat, Jepang, Hongkong, Singapura dan Korea Selatan. Sumber utama data berasal dari International Financial Statistic yang diterbitkan oleh IMF.Teknik estimasi data gameboard digunakan untuk mengetahui seberapa besar pengaruh international reserves yang digunakan dalam rangka stabilisasi nilai tukar akibat terms of trade shock. Selain itu archetype ini juga diperunakan untuk melihat bagaimana peran financial deepening suatu negara dalam stabilisasi nilai tukar ini. moulding persamaan yang diestimasi, dikembangkan dari penelitian (Aizenman dan Crichton, 2006), yakni1. type international reserves mitigation terms (III.4)2. Model financial deepening mitigation terms Dimana RER adalah nilai tukar riil (Real Exchange Rate) ETOT adalah efektifitas nilai tukar perdagangan yang dinilai dari keterbukaan perdagangan (Trade Openness) yang dikalikan dengan nilai tukar perdagangan (Terms of Trade) RES adalah cadangan internasional (International reserves) FD adalah kedalaman sektor keuangan (Financial Deepening) i adalah fluffection indentification t adalah judgment of conviction serial publication appellative it adalah Koefisien pengganggu (error terms) 4.Varian pertama dari teknik estimasi data panel adalah pendekatan pooled least(prenominal) square(a) (PLS) yang secara sederhana menggabungkan seluruh data cartridge holder series dan traverse section dan kemudian mengestimasi nonplus dengan menggunakan metode ordinary least square (OLS) 5. Pendekatan kedua adalah unbending effect sit down (FEM) yang memperhitungkan kem ungkinan perbedaan beg antar individu yang ditunjukkan dengan kehadiran i pada persamaan (III.6). Secara teknis, amaze dengan firm effect menambahkan weed variables sebanyak N-1 buah ketika terdapat N individu. Pendekatan ketiga adalah hit-or-miss effect deterrent example (REM) yang dapat memperbaiki efisiensi proses least square dengan memperhitungkan error dari magazine series dan cross section.Berbeda dengan FEM, model REM memperlakukan intercept sebagai random variable dengan rata-rata dengan stokastik terms it. Model random effect adalah variasi dari estimasi reason least square (GLS). Model data panel untuk masing-masing varian teknik tersebut adalah sebagai berikut (Gujarati, 2003 640)a. Pooled Least uncoiled(III.6)b. pertinacious gear up(III.7)c. haphazard Effect(III.8)Pada dasarnya penggunaan metode data panel memiliki beberapa keunggulan (Widarjono, 2005 254). Pertama, panel data mampu memperhitungkan heterogenitas individu secara eksplisit dengan mengijinkan v ariabel spesifik individu. Kemampuan mengontrol heterogenitas4 Definisi operasional variabel lebih detail dapat dilihat dilampiran IV.A. 5 Lihat Baltagi, 2002 Gujarati, 2003 Maddala 1993 Pindyck dan Rubinfeld, 1998.individu ini pada gilirannya menjadikan data panel dapat digunakan untuk menguji dan membangun model perilaku yang lebih kompleks. Kedua, jika efek spesifik signifikan berkorelasi dengan variabel penjelas lainnya, penggunaan panel data akan mengurangi masalah omitted variables secara substansial. Ketiga, data panel mendasarkan diri pada observasi cross section yang berulang-ulang (time series), sehingga metode data panel cocok untuk digunakan sebagai study of dynamic adjustment. Keempat, tingginya jumlah observasi memiliki implikasi pada data yang lebih informatif, lebih variatif, kolinearitas antar variabel yang semakin berkurang dan peningkatan derajat kebebasan (degree of freedom), sehingga dapat diperoleh hasil estimasi yang lebih efisien. Kelima, data panel dapat digunakan untuk mempelajari model-model perilaku yang kompleks. Keenam, data panel dapat meminimalisir bias yang mungkin ditimbulkan oleh agregasi data individu. Keunggulan-keunggulan tersebut diatas memiliki implikasi pada tidak diperlukannya pengujian asumsi klasik dalam model data panel, sesuai apa yang ada dalam beberapa literatur yang digunakan dalam penelitian ini6.Dalam estimasi selanjutnya sebagai persyaratan estimasi regresi data panel, perlu di pilih penggunaan antara pooled least square, random effect model atau fixed effect model. Ketiga model tersebut akan berbeda dalam intrepetasi selanjutnya sehingga perlu dilakukan pemilihan model untuk memperoleh estimasi yang efisien sesuai dengan penggunaan regresi data panel. Pertama uji statistik F digunakan untuk memilih antara metode PLS tanpa variabel dummy atau memilih fit(p) Effect. Keduauji Lagrange Multiplier (LM) digunakan untuk memilih antara OLS tanpa variabel dummy atau memilih Random Effect. Terakhir, untuk memilih antara Fixed Effect Model (FEM) atau Random Effect Model (REM) digunakan uji yang dikemukakan oleh Hausman.Jika data time series lebih besar dibandingkan data cross section maka teknik efek acak (REM) kurang tepat atau tidak dapat dipakai untuk mengestimasi suatu model (Telisa, 200430)7. Dalam model penelitian ini teknik Random Effect Model (REM) tidak dapat digunakan, karena pada penelitian ini jumlah time series (28 time series) lebih besar dibandingkan dengan jumlah cross section (6 cross section). Oleh sebab itu pemilihan teknik estimasi dalam penelitian ini hanya memilih diantara dua teknik estimasi yaitu PLS (Pooled Least Square) atau FEM (Fixed Effect Model). Hasil pengujian menyarankan penggunaan Model Fixed Effect (Unrestricted) dalam penelitian ini.6 Lihat Maddala, 1998 Pindyck Rubinfeld, 1991 Greene, 2003 Gujarati, 2003 Widarjono, 2005. 7 IbidIV. HASIL DAN ANALISAIV.1. Model International Reserves extenuation TermsBerdasarkan hasil pengolahan data dalam tabel III.1. ko efisien determsinasi model International Reserves Mitigation Terms untuk keseluruhan negara adalah sebesar 0.999602 sedangkan untuk estimasi spesifik masing-masing negara adalah sebesar 0.999845. Artinya variasi variabel independen dalam model tersebut mampu menjelaskan variasi dari variabel dependen kedua model tersebut masing-masing sebesar 99,96% dan 99,98%. Secara simultan, variabel-variabel yang digunakan dalam estimasi keseluruhan maupun estimasi spesifik memiliki pengaruh yang signifikan, kondisi tersebut dapat diketahui dari nilai Fyang masing-masing sebesar 57441.05 dan 57032.28. Nilai tersebut melebihi nilai kritis yang dipersyaratkan sesuai dengan F-tabel hingga taraf signifikansi 1%. Dengan demikian nilai F Fyang berarti Hditolak. Secara parsial sebagaimana terdapat dalam tabel dibawah menunjukkan pengaruh masing-masing variabel bebas yang signifikan terhadap variabel nilai tukar riil (variabel dependen) pada estimasi secara keseluruhan. Namun untuk estimasi spesifik mas ing-masing negara hanya variabel trenchant terms of trade Indonesia, reserves mitigation terms Indonesia, Korea dan Amerika yang signifikan secara statistik mempengaruhi vriabel real exchange rate.Sumber Hasil pengolahan Keterangan * = Signifikan 1% **=Signifikan 5%.Dari estimasi secara keseluruhan dalam tabel diatas terlihat bahwa pengaruh utile terms of trade (ETOT) terhadap real exchange rate (RER) adalah positif. Temuan empiris ini tidak sesuai dengan teori yang digunakan dalam penelitian, yaitu diharapkan bernilai negatif. Dengan asumsi bahwa peningkatan real exchange rate merupakan depresiasi nilai tukar domestik atau apresiasi nilai tukar mitra dagang, maka peningkatan pada useful terms of trade suatu negara terhadap negara-negara mitra dagangnya cenderung meningkatkan (depresiasi) real exchange rate. Rata-rata effective terms of trade keseluruhan negara obyek penelitian adalah 1,82, dengan perubahan pada real exchange rate rata-rata apresiasi sebesar 0,04%.Berdasarkan has il estimasi menunjukkan bahwa elastisitas real exchange rate terhadap effective terms of trade shock ialah kenaikan effective terms of trade sebesar 1% mempengaruhi real exchange rate sebesar 0.28%. Dapat diartikan bahwa perbaikan effective terms of trade akan menyebabkan mata uang luar negeri mengalami apresiasi terhadap mata uang dalam negeri. Kondisi demikian menggambarkan bahwa keterbukaan perdagangan memiliki sisi negatif yaitu kecenderungan untuk melemahkan nilai tukar suatu negara ketika terjadi penurunan kinerja perekonomian negara mitra dagang tersebut dan dengan dukungan trade openness dan effective terms of trade yang semakin meningkat. Kondisi ini secara aktual dapat digambarkan pada resesi global pada saat ini yang hampir tidak sedikitpun negara yang menuai imbas negatif. Hampir seluruh perekonomian dunia termasuk nilai tukarnya cenderung terdepresiasi dan perekonomian berjalan lambat.Ketidaksesuaian hasil ini dimungkinkan juga dikarenakan kekuatan pasar yang mempengaru hi fluktuasi nilai tukar. Aliran modal jangka pendek, aliran keuangan internasional baik dari pemerintah maupun swasta yang erat kaitannya dengan keterbukaan perekonomian suatu negara memungkinkan berpengaruh pada nilai tukar riil. Besaran (magnitude) effective terms of trade dalam mempengaruhi pasar nilai tukar dapat dikatakan terlalu kecil jika dibandingkan dengan varabel-variabel lain yang berkaitan dengan nilai tukar.Berdasarkan hasil estimasi dapat dikemukakan bahwa peningkatan atau perbaikan pada effective terms of trade suatu negara berdampak pada peningkatan (apresiasi) nilai tukar riil negara lain sebagai mitra dagang utamanya atau penurunan (depresiasi) nilai tukar pada negaranya sendiri. Dapat dikatakan pula bahwa perbaikan yang terjadi pada effective terms of trade suatu negara menguntungkan negara mitra dagangnya dari sisi nilai tukar, namun tidak untuk negaranya sendiri. Hal ini merupakan efek negatif keterbukPerkembanganPerkembanganCADANGAN DEVISA, FINANCIAL DEEPENING DAN STABILISASI NILAI TUKAR RIIL RUPIAH AKIBAT GEJOLAK NILAI TUKAR PERDAGANGANAbstractThese papers analyze the influence of the international reserves and the financial deepening on the real exchange rate stabilization due to the terms of trade shock.

PENDAHULUANPerkembangan ekonomi Indonesia dewasa ini menunjukkan semakin terintegrasi dengan perekonomian dunia. Hal ini merupakan konsekuensi dari dianutnya sistem perekonomian terbuka yang dalam aktivitasnya selalu berhubungan dan tidak lepas dari fenomena hubungan internasional. Adanya keterbukaan perekonomian ini memiliki dampak pada perkembangan neraca pembayaran suatu negara yang meliputi arus perdagangan dan lalu lintas modal terhadap luar negeri suatu negara.Salah satu bentuk aliran modal yang masuk ke dalam negeri yaitu dapat berupa devisa yang berasal dari perdagangan internasional yang dilakukan oleh negara tersebut. Meningkatnya ekspor suatu negara akan membawa keuntungan yaitu kenaikan pendapatan, kenaikan devisa, transfer modal dan makin banyaknya kesempatan kerja. Demikian pula meningkatnya impor suatu negara akan memberikan lebih banyak alternatif barang-barang yang dapat d ikonsumsi dan terpenuhinya kebutuhan bahan-bahan baku penolong serta barang modal untuk kebutuhan industri di negara-negara tersebut dan transfer teknologi.Perdagangan internasional akan terjadi pada suatu perbandingan harga tertentu yaitu antara harga ekspor dan harga impor yang sering disebut nilai tukar perdagangan (terms of trade, TOT).

TOT yang disimbolkan dengan N dihitung sebagai perbandingan antara indeks harga ekspor (Px) dengan indeks harga impor (Pm) atau N = Px/Pm (Nopirin 1992 71). Kenaikan N menunjukkan perbaikan di dalam Terms of Trade. Perbaikan terms of trade ini dapat timbul sebagai akibat nilai perubahan harga ekspor yang lebih besar realatif terhadap harga impor.Perbaikan terms of trade akan meningkatkan pendapatan negara tersebut dari perdagangan demikian sebaliknya. Selain mempengaruhi pendapatan negara, per gerakan TOT juga mempengaruhi nilai tukar riil, (Mankiw, 2000 195). Upaya untuk mengatasi pengaruh memburuknya terms of trade terhadap nilai tukar ini dapat menggunakan cadangan devisa (international reserves) yang dimiliki negara yang bersangkutan. Hal ini dibuktikan oleh penelitian Aizenman and Crichton (2006), menyebutkan bahwa negara-negara yang mengekspor barangbarang sumberdaya alam memiliki volatilitas terms of trade yang 3 kali lebih volatil dibandingkan negara-negara yang mengekspor barang manufaktur. Selain besaran pergerakan TOT, volatilitas ini juga mempengaruhi nilai tukar riil suatu negaraPada dasarnya international reserves berfungsi sebagai buffer stock untuk berjaga-jaga guna menghadapi ketidakpastian keadaan yang akan datang. Sehingga, apabila terjadi depresiasi nilai tukar riil akibat memburuknya terms of trade maka disitulah international reserves berfungsi sebagai penstabil. Perbaikan terms of trade akan meningkatkan aliran modal masuk sehingga akan kembali mend orong apresiasi nilai tukar riil.Seperti halnya penelitian yang dilakukan oleh Rajan dan Siregar (2004), diperoleh bahwa reserves merupakan kunci utama dari suatu negara untuk dapat menghindari krisis ekonomi dan keuangan. Terutama bagi negara-negara dengan perekonomian yang terbuka dimana aliran modal internasional adalah volatil atau rentan terhadap terjadinya shock yang merambat dari negara lain (contagion effect). Bahwa dengan melihat pengalaman krisis yang terjadi pada tahun 1997, negara yang memiliki reserves yang besar dapat menghindari contagion effect dari krisis dengan lebih baik dibandingkan dengan negara yang memiliki reserves yang kecil.Upaya untuk mengatasi gejolak nilai tukar akibat terms of trade shock selain dengan international reserves juga dapat diatasi dengan mengukur financial deepening (kedalaman sektor keuangan) suatu negara. Financial deepening diukur melalui rasio M2 dibagi GDP (Gross Domestic Product). Penggunaan rasio ini dikarenakan merupakan rasio palin g umum yang digunakan untuk mengukur perkembangan sektor keuangan suatu negara. Hasil rasio ini akan menunjukkan rasio penggunaan M2 untuk menghasilkan setiap GDP.

Bahkan dalam masa krisis pasar modal global 2008 ini, Bank Indonesia mewajibkan pengguna valas untuk melaporkan peruntukannya jika melebihi US$10.000 per bulan.Permasalahan mendasar yang diangkat dalam penelitian in i diantaranya 1) Bagaimanakah pengaruh international reserves dalam perannya sebagai penstabil nilai tukar riil akibat terms of trade shock. 2) Bagaimanakah pengaruh financial deepening dalam perannya sebagai penstabil nilai tukar riil akibat terms of trade shock. Kedua permasalahan tersebut akan dibahas bagaimanakah pengaruhnya di keseluruhan obyek penelitian dan juga secara spesifik setiap Negara untuk memperoleh perbandingan antar Negara, khususnya antara Indonesia dengan Negara-negara mitra dagang utama (Amerika serikat, Jepang, Singapura, Korea Selatan dan Hongkong).II. TEORIII.1. International ReservesThe need of a central bank for international reserves is similar to an individuals desire to hold cash balances (currency and checkable deposits) (Carbaugh, 2004 513). Dari pernyataan tersebut dapat disimpulkan bahwa kebutuhan international reserves bagi suatu negara mempunyai tujuan dan manfaat seperti halnya manfaat kekayaan bagi suatu individu. Motif kepemilikan international reserves dapat disamakan dengan motif seseorang untuk memegang uang yaitu untuk motif transaksi, motif berjaga-jaga dan motif spekulasi. Motif transaksi antara lain untuk membiayai transaksi impor yang dilakukan oleh pemerintah dalam rangka mendukung proses pembangunan, motif berjaga-jaga berkaitan dengan mengelola nilai tukar, serta motif yang ketiga adalah untuk lebih memenuhi kebutuhan diversifikasi kekayaan (memperoleh return dari kegiatan investasi dengan international reserves (Gandhi, 2006 1).Jhingan (2001) menyatakan bahwa International liquidity (generally used as a synonym for international reserves) is defined as the aggregate stock of internally acceptable assets held by the central bank to settle a deficit in a countrys balance of payments. International reserves merupakan asset dari bank sentral yang dipergunakan untuk mengatasi ketidakseimbangan neraca pembayaran. Definisi tersebut senada dengan konsep International Reserves and Foreign Currency Lliquidity (IRFCL) yan g dikeluarkan oleh IMF bahwa international reserves didefinisikan sebagai seluruh aktiva luar negeri yang dikuasai oleh otoritas moneter dan dapat digunakan setiap waktu guna membiayai ketidakseimbangan neraca pembayaran atau dalam rangka stabilitas moneter 3.3 Guidelines for International Reserves and Foreign Currency Liquidity, IMF, 2001.Sedangkan menurut Salvatore (1996 513), bahwa international reserves merupakan asset-asset likuid dan berharga tinggi yang dimiliki suatu negara yang nilainya diakui atau diterima oleh masyarakat internasional dan dapat dipakai sebagai alat-alat pembayaran yang sah bagi pemerintah atau negara yang merupakan pemiliknya dalam mengadakan transaksi-transaksi atau pembayaran internasional. Selain untuk tujuan stabilisasi nilai tukar, terkait dengan neraca pembayaran international reserves dapat digunakan untuk membiayai impor dan membayar kewajiban luar negeri. Besar kecilnya akumulasi international reserves suatu negara biasanya ditentukan oleh kegiat an perdagangan (ekspor dan impor) serta arus modal negara tersebut.Kecukupan international reserves ditentukan oleh besarnya kebutuhan impor dan sistem nilai tukar yang digunakan. Dalam sistem nilai tukar yang mengambang bebas, fungsi international reserves adalah untuk menjaga stabilitas nilai tukar hanya terbatas pada tindakan untuk mengurangi fluktuasi nilai tukar yang terlalu tajam. Oleh karena itu, international reserves yang dibutuhkan tidak perlu sebesar international reserves yang dibutuhkan apabila negara tersebut mengadopsi sistem nilai tukar tetap. Wujud utama dari international reserves adalah emas, hard currencies yang pada umumnya dalam bentuk empat jenis mata uang utama yang dianggap paling berpengaruh di dunia, yaitu US dollar, Euro, Poundsterling dan Yen serta surat-surat berharga terbitan IMF yang biasa disebut sebagai Special Drawing Rights (SDRs). Penjelasan lebih rinci mengenai komponen international reserves sebagaimana dijelaskan oleh Gandhi (2006 4).Berkaitan dengan sifat dari rezim nilai tukar (sistem nilai tukar tetap, mengambang dan mengambang terkendali) di negara yang menganut sistem nilai tukar tetap pada umumnya memerlukan international reserves yang besar untuk mempertahankan nilai tukar pada level yang ditetapkan. Hal ini dikarenakan oleh ketakutan negara itu akan ketidakpastian dalam sistem nilai tukar mengambang bebas yang diterapkannya. Sehingga, sebagai upaya untuk berjagajaga dalam menghadapi fluktuasi nilai tukarnya otoritas moneter negara tersebut membutuhkan international reserves dalam jumlah yang dianggap memadai guna stabilisasi nilai tukar.Pada sistem nilai tukar mengambang, terjadinya pergerakan nilai tukar dapat diatasi sendiri oleh mekanisme pasar, sehingga jumlah international reserves yang dibutuhkan tidak sebanyak yang dibutuhkan oleh suatu negara dengan sistem nilai tukar tetap yang rigid. Menurut Carbaugh (2004 516), tujuan utama dari international reserves adalah untuk memfasilitasi pemerintah dalam melakuk an intervensi pasar sebagai upaya untuk menstabilkan nilai tukar. Sehingga, suatu negara dengan aktivitas stabilisasi yang aktif memerlukan jumlah international reserves yang besar pula.Keterbukaan perekonomian suatu negara tercermin dengan semakin besarnya transaksi perdagangan dan aliran modal antar negara. Semakin terbuka perekonomian suatu negara kebutuhan international reserves-nya cenderung semakin besar guna membiayai transaksi perdagangan. Parameter yang biasa dipakai untuk mengukur kecukupan international reserves sehubungan dengan transaksi perdagangan antar negara adalah marginal propensity to import. Semakin besar angka propensity tersebut menunjukkan semakin besarnya kebutuhan international reserves yang harus dimiliki dan semakin kecil angka propensity tersebut menunjukkan semakin kecilnya kebutuhan international reserves yang harus dimiliki (Gandhi, 2006 11). Dengan tersedianya international reserves yang mencukupi maka apabila suatu negara mengahadapi kondisi terms o f trade yang buruk yang kemudian akan berpengaruh pada nilai tukar riilnya maka international reserves dapat berperan sebagai absorber.II.2. Nilai Tukar Perdagangan (Terms of Trade)Terdapat beberapa konsep tentang TOT. Konsep pertama merupakan konsep yang paling umum digunakan, yaitu net barter terms of trade atau juga dapat disebut commodity terms of trade. Net barter terms of trade adalah perbandingan antara indeks harga ekspor dengan indeks harga impor. Kenaikan ekspor menunjukkan perbaikan di dalam nilai tukar perdagangan, artinya untuk sejumlah tertentu ekspor dapat diperoleh jumlah impor yang lebih banyak dengan melalui hubungan harga (Nopirin, 1995 71).Forumulasinya dapat dituliskan dengan rumus sebagai berikut(III.1)Dimana, Px adalah Indeks harga ekspor Pm adalah Indeks harga impor dan 100 adalah Indeks tahun dasar. Bila N 100 atau terjadi kenaikan net barter terms of trade maka berarti terjadi perkembangan perdagangan luar negeri yang positif karena dengan nilai ekspor tert entu diperoleh nilai impor yang lebih besar (Hady, 200177).Konsep kedua adalah gross barter terms of trade, merupakan perbandingan antara indeks volume impor dengan indeks volume ekspor. Konsep ini menjadi tidak penting karena kurang memberikan gambaran tentang perubahan harga. Oleh karena itu, apabila konsep terms of trade tanpa diberi penjelasan apa-apa maka yang dimaksud adalah konsep net barter terms of trade.Konsep ketiga adalah income terms of trade yang dapat dituliskan dengan rumus sebagai berikut (III.2)Dimana N adalah net barter terms of trade Px adalah Indeks harga ekspor Pm adalah Indeks harga impor dan Qx adalah Indeks kuantitas ekspor.Berdasarkan konsep ini, kenaikan income terms of trade menunjukkan bahwa suatu negara dapat memperoleh jumlah impor yang lebih besar dengan dasar kenaikan nilai ekspornya. Bagi negara-negara yang sedang berkembang, selain variabel harga juga sangat penting untuk menilai terms of trade ini dengan mempertimbangkan volume ekspornya karena ke naikan harga ekspor yang tinggi mungkin diimbangi dengan turunnya volume ekspor.Perbaikan TOT dapat timbul sebagai akibat (1) harga ekspor naik sedang harga impor tetap (2) harga ekspor tetap sedang harga impor turun (3) harga ekspor naik dengan proporsi yang lebih besar daripada naiknya harga impor (4) harga ekspor turun dengan proporsi yang lebih kecil daripada turunnya harga impor.Mekanisme bagaimana TOT dapat berpengaruh pada nilai tukar riil adalah dapat dilihat dari sebuah mekanisme sederhana yaitu perbaikan TOT akan meningkatkan aliran modal masuk yang berasal dari perdagangan yang selanjutnya dapat mengapresiasi nilai tukar riil dan sebaliknya. Memburuknya TOT akan mengakibatkan permintaan valuta asing meningkat sehingga akan mendepresiasi nilai tukar riil.Terkait dengan jenis produksi yang diperdagangkan, maka secara umum nilai tukar perdagangan komoditi (commodity terms of trade atau net barter terms of trade) negaranegara berkembang cenderung mengalami kemerosotan dari wa ktu ke waktu. Salah satu penyebab utamanya adalah sebagian besar atau bahkan semua kenaikan produktivitas yang terjadi di negara-negara maju dialirkan ke para pekerjanya dalam bentuk upah dan pendapatan yang lebih tinggi, sedangkan sebagian besar atau seluruh kenaikan produktivitas yang berlangsung di negara-negara berkembang diwujudkan sebagai harga-harga produk yang lebih murah (Salvatore, 1996 431).II.3. Nilai Tukar Riil (Real Exchange Rate) dan Pasar ValasSetiap negara memiliki sebuah mata uang yang menunjukkan harga-harga barang dan jasa. Pengertian nilai tukar valuta asing adalah Exchange rate is the price of one nations money in terms of another nations money. The nominal exchange rate is usually called the exchange rate. Menurut definisi tersebut nilai tukar diartikan sebagai harga suatu mata uang terhadap mata uang negara lain. Nilai tukar nominal biasa disebut nilai tukar (exchange rate) (Pugel, 2004). Menurut Mankiw, nilai tukar nominal adalah harga relatif dimana seseor ang dapat memperdagangkan mata uang suatu negara dengan mata uang lainnya (Mankiw, 2000 200).Dengan menggunakan suatu indeks harga untuk Indonesia (P), sebuah indeks harga untuk harga-harga di luar negeri (P*) dan nilai tukar nominal antara rupiah dengan mata uang asing (e), akan dapat diukur nilai tukar riil keseluruhan antara Indonesia dengan negara-negara lain sebagai berikut Nilai Tukar Riil = (e x P) / P* (III.3)Terdapat paling tidak 3 faktor utama yang mempengaruhi permintaan valuta asing. Pertama, faktor pembayaran impor. Semakin tinggi impor barang dan jasa, maka semakin besar permintaan terhadap valuta asing sehingga nilai tukar akan cenderung melemah. Kedua, faktor aliran modal keluar (capital outflow). Semakin besar aliran modal keluar, maka semakin besar permintaan valuta asing dan pada kelanjutannya akan memperlemah nilai tukar. Aliran modal keluar meliputi pembayaran hutang penduduk Indonesia (baik swasta dan pemerintah) kepada pihak asing dan penempatan dana penduduk Indonesia ke luar negeri. Ketiga, kegiatan spekulasi. Semakin banyak kegiatan spekulasi valuta asing yang dilakukan oleh spekulan, maka semakin besar permintaan terhadap valuta asing sehingga memperlemah nilai tukar mata uang lokal terhadap mata uang asing.Sementara itu, penawaran valuta asing dipengaruhi oleh dua faktor utama. Pertama, faktor penerimaan hasil ekspor. Semakin besar volume penerimaan ekspor barang dan jasa, maka semakin besar jumlah valuta asing yang dimiliki oleh suatu negara dan pada lanjutannya nilai tukar terhadap mata uang asing cenderung menguat atau apresiasi. Kedua, faktor aliran modal masuk (capital inflow). Semakin besar aliran modal masuk, maka nilai tukar akan cenderung semakin menguat. Aliran modal masuk tersebut dapat berupa penerimaan hutang luar negeri, penempatan dana jangka pendek oleh pihak asing (portofolio investment) dan investasi langsung pihak asing (foreign direct investment) (Simorangkir dan Suseno, 2004 6).II.4. Financial DeepeningUkuran da ri perkembangan intermediasi keuangan biasanya digunakan pengukuran indikator melalui kuantitas, kualitas, dan efisiensi dari jasa intermediasi keuangan (Calderon, 20025). Terdapat beberapa indikator untuk mengetahui seberapa besar tingkat perkembangan sektor keuangan salah satu diantaranya adalah rasio antara aset keuangan dalam negeri terhadap GDP (Muklis, 2005 2).Menurut King dan Levine (1993), Financial deepening means an increase in the money supply of financial assets in the economy, it is important to develop some measures of the widest range of financial assets, including money. Selain itu, King dan Levine merancang 4 ukuran dalam perhitungan perkembangan sektor keuangan. Pertama, ukuran dari kedalaman sektor keuangan adalah rasio dari kewajiban lancar (liquid liabilities) dari sistem keuangan terhadap GDP. Kewajiban lancar dalam hal ini adalah M3, namun apabila M3 tidak bisa didapatkan maka digunakan M2. Hal ini sejalan dengan IMF dalam database International Financial Stat istic dan juga Slangor (199111). Kedua, adalah rasio dari deposit money bank domestic asset dibagi dengan deposit money bank domestic asset ditambah dengan central bank domestic asset yang menggambarkan institusi keuangan yang lebih spesifik. Ketiga, rasio kredit dari sektor swasta non keuangan dibagi dengan total kredit domestik. Keempat, adalah rasio kredit sektor swasta non-keuangan dibagi dengan GDP. Dua yang terakhir ini menggambarkan ukuran kuangan sektor dan tingkat pinjaman publik (King dan Levine, 1993 4).Penggunaan rasio M2 terhadap GDP sebagai indikator financial deepening juga dibenarkan oleh King dan Levine, (1993 5). Semakin kecil rasio tersebut maka semakin dangkal sektor keuangan suatu negara. Suatu negara dikatakan memiliki sektor keuangan yang dalam apabila M2 20% dari GDP dan dangkal apabila M2 III. METODOLOGIJenis data yang digunakan dalam penelitian ini adalah data sekunder dan merupakan data panel, mencakup periode 2000Q1 2006Q4 dan 6 negara yakni Indonesia d an 5 negara mitra dagang utamanya yaitu Amerika Serikat, Jepang, Hongkong, Singapura dan Korea Selatan. Sumber utama data berasal dari International Financial Statistic yang diterbitkan oleh IMF.Teknik estimasi data panel digunakan untuk mengetahui seberapa besar pengaruh international reserves yang digunakan dalam rangka stabilisasi nilai tukar akibat terms of trade shock. Selain itu model ini juga diperunakan untuk melihat bagaimana peran financial deepening suatu negara dalam stabilisasi nilai tukar ini. Model persamaan yang diestimasi, dikembangkan dari penelitian (Aizenman dan Crichton, 2006), yakni1. Model international reserves mitigation terms (III.4)2. Model financial deepening mitigation terms Dimana RER adalah nilai tukar riil (Real Exchange Rate) ETOT adalah efektifitas nilai tukar perdagangan yang dinilai dari keterbukaan perdagangan (Trade Openness) yang dikalikan dengan nilai tukar perdagangan (Terms of Trade) RES adalah cadangan internasional (International reserves ) FD adalah kedalaman sektor keuangan (Financial Deepening) i adalah crossection indentification t adalah time series identification it adalah Koefisien pengganggu (error terms) 4.Varian pertama dari teknik estimasi data panel adalah pendekatan pooled least square (PLS) yang secara sederhana menggabungkan seluruh data time series dan cross section dan kemudian mengestimasi model dengan menggunakan metode ordinary least square (OLS) 5. Pendekatan kedua adalah fixed effect model (FEM) yang memperhitungkan kemungkinan perbedaan intercept antar individu yang ditunjukkan dengan kehadiran i pada persamaan (III.6). Secara teknis, model dengan fixed effect menambahkan dummy variables sebanyak N-1 buah ketika terdapat N individu. Pendekatan ketiga adalah random effect model (REM) yang dapat memperbaiki efisiensi proses least square dengan memperhitungkan error dari time series dan cross section.Berbeda dengan FEM, model REM memperlakukan intercept sebagai random variable dengan rata-rata de ngan stokastik terms it. Model random effect adalah variasi dari estimasi generalized least square (GLS). Model data panel untuk masing-masing varian teknik tersebut adalah sebagai berikut (Gujarati, 2003 640)a. Pooled Least Square(III.6)b. Fixed Effect(III.7)c. Random Effect(III.8)Pada dasarnya penggunaan metode data panel memiliki beberapa keunggulan (Widarjono, 2005 254). Pertama, panel data mampu memperhitungkan heterogenitas individu secara eksplisit dengan mengijinkan variabel spesifik individu. Kemampuan mengontrol heterogenitas4 Definisi operasional variabel lebih detail dapat dilihat dilampiran IV.A. 5 Lihat Baltagi, 2002 Gujarati, 2003 Maddala 1993 Pindyck dan Rubinfeld, 1998.individu ini pada gilirannya menjadikan data panel dapat digunakan untuk menguji dan membangun model perilaku yang lebih kompleks. Kedua, jika efek spesifik signifikan berkorelasi dengan variabel penjelas lainnya, penggunaan panel data akan mengurangi masalah omitted variables secara substansial. Ketiga, data panel mendasarkan diri pada observasi cross section yang berulang-ulang (time series), sehingga metode data panel cocok untuk digunakan sebagai study of dynamic adjustment. Keempat, tingginya jumlah observasi memiliki implikasi pada data yang lebih informatif, lebih variatif, kolinearitas antar variabel yang semakin berkurang dan peningkatan derajat kebebasan (degree of freedom), sehingga dapat diperoleh hasil estimasi yang lebih efisien. Kelima, data panel dapat digunakan untuk mempelajari model-model perilaku yang kompleks. Keenam, data panel dapat meminimalisir bias yang mungkin ditimbulkan oleh agregasi data individu. Keunggulan-keunggulan tersebut diatas memiliki implikasi pada tidak diperlukannya pengujian asumsi klasik dalam model data panel, sesuai apa yang ada dalam beberapa literatur yang digunakan dalam penelitian ini6.Dalam estimasi selanjutnya sebagai persyaratan estimasi regresi data panel, perlu di pilih penggunaan antara pooled least square, random effec t model atau fixed effect model. Ketiga model tersebut akan berbeda dalam intrepetasi selanjutnya sehingga perlu dilakukan pemilihan model untuk memperoleh estimasi yang efisien sesuai dengan penggunaan regresi data panel. Pertama uji statistik F digunakan untuk memilih antara metode PLS tanpa variabel dummy atau memilih Fixed Effect. Keduauji Lagrange Multiplier (LM) digunakan untuk memilih antara OLS tanpa variabel dummy atau memilih Random Effect. Terakhir, untuk memilih antara Fixed Effect Model (FEM) atau Random Effect Model (REM) digunakan uji yang dikemukakan oleh Hausman.Jika data time series lebih besar dibandingkan data cross section maka teknik efek acak (REM) kurang tepat atau tidak dapat dipakai untuk mengestimasi suatu model (Telisa, 200430)7. Dalam model penelitian ini teknik Random Effect Model (REM) tidak dapat digunakan, karena pada penelitian ini jumlah time series (28 time series) lebih besar dibandingkan dengan jumlah cross section (6 cross section). Oleh sebab itu pemilihan teknik estimasi dalam penelitian ini hanya memilih diantara dua teknik estimasi yaitu PLS (Pooled Least Square) atau FEM (Fixed Effect Model). Hasil pengujian menyarankan penggunaan Model Fixed Effect (Unrestricted) dalam penelitian ini.6 Lihat Maddala, 1998 Pindyck Rubinfeld, 1991 Greene, 2003 Gujarati, 2003 Widarjono, 2005. 7 IbidIV. HASIL DAN ANALISAIV.1. Model International Reserves Mitigation TermsBerdasarkan hasil pengolahan data dalam tabel III.1. koefisien determsinasi model International Reserves Mitigation Terms untuk keseluruhan negara adalah sebesar 0.999602 sedangkan untuk estimasi spesifik masing-masing negara adalah sebesar 0.999845. Artinya variasi variabel independen dalam model tersebut mampu menjelaskan variasi dari variabel dependen kedua model tersebut masing-masing sebesar 99,96% dan 99,98%. Secara simultan, variabel-variabel yang digunakan dalam estimasi keseluruhan maupun estimasi spesifik memiliki pengaruh yang signifikan, kondisi tersebut dap at diketahui dari nilai Fyang masing-masing sebesar 57441.05 dan 57032.28. Nilai tersebut melebihi nilai kritis yang dipersyaratkan sesuai dengan F-tabel hingga taraf signifikansi 1%. Dengan demikian nilai F Fyang berarti Hditolak. Secara parsial sebagaimana terdapat dalam tabel dibawah menunjukkan pengaruh masing-masing variabel bebas yang signifikan terhadap variabel nilai tukar riil (variabel dependen) pada estimasi secara keseluruhan. Namun untuk estimasi spesifik masing-masing negara hanya variabel effective terms of trade Indonesia, reserves mitigation terms Indonesia, Korea dan Amerika yang signifikan secara statistik mempengaruhi vriabel real exchange rate.Sumber Hasil pengolahan Keterangan * = Signifikan 1% **=Signifikan 5%.Dari estimasi secara keseluruhan dalam tabel diatas terlihat bahwa pengaruh effective terms of trade (ETOT) terhadap real exchange rate (RER) adalah positif. Temuan empiris ini tidak sesuai dengan teori yang digunakan dalam penelitian, yaitu diharapkan b ernilai negatif. Dengan asumsi bahwa peningkatan real exchange rate merupakan depresiasi nilai tukar domestik atau apresiasi nilai tukar mitra dagang, maka peningkatan pada effective terms of trade suatu negara terhadap negara-negara mitra dagangnya cenderung meningkatkan (depresiasi) real exchange rate. Rata-rata effective terms of trade keseluruhan negara obyek penelitian adalah 1,82, dengan perubahan pada real exchange rate rata-rata apresiasi sebesar 0,04%.Berdasarkan hasil estimasi menunjukkan bahwa elastisitas real exchange rate terhadap effective terms of trade shock ialah kenaikan effective terms of trade sebesar 1% mempengaruhi real exchange rate sebesar 0.28%. Dapat diartikan bahwa perbaikan effective terms of trade akan menyebabkan mata uang luar negeri mengalami apresiasi terhadap mata uang dalam negeri. Kondisi demikian menggambarkan bahwa keterbukaan perdagangan memiliki sisi negatif yaitu kecenderungan untuk melemahkan nilai tukar suatu negara ketika terjadi penurunan kinerja perekonomian negara mitra dagang tersebut dan dengan dukungan trade openness dan effective terms of trade yang semakin meningkat. Kondisi ini secara aktual dapat digambarkan pada resesi global pada saat ini yang hampir tidak sedikitpun negara yang menuai imbas negatif. Hampir seluruh perekonomian dunia termasuk nilai tukarnya cenderung terdepresiasi dan perekonomian berjalan lambat.Ketidaksesuaian hasil ini dimungkinkan juga dikarenakan kekuatan pasar yang mempengaruhi fluktuasi nilai tukar. Aliran modal jangka pendek, aliran keuangan internasional baik dari pemerintah maupun swasta yang erat kaitannya dengan keterbukaan perekonomian suatu negara memungkinkan berpengaruh pada nilai tukar riil. Besaran (magnitude) effective terms of trade dalam mempengaruhi pasar nilai tukar dapat dikatakan terlalu kecil jika dibandingkan dengan varabel-variabel lain yang berkaitan dengan nilai tukar.Berdasarkan hasil estimasi dapat dikemukakan bahwa peningkatan atau perbaikan pada effective terms of trade suatu negara berdampak pada peningkatan (apresiasi) nilai tukar riil negara lain sebagai mitra dagang utamanya atau penurunan (depresiasi) nilai tukar pada negaranya sendiri. Dapat dikatakan pula bahwa perbaikan yang terjadi pada effective terms of trade suatu negara menguntungkan negara mitra dagangnya dari sisi nilai tukar, namun tidak untuk negaranya sendiri. Hal ini merupakan efek negatif keterbuk

This intimationmill was later on developed to founder electricity and was renamed a wind turbine. 3 On the other hand a wind turbine is a machine which extracts energy from wind to depict electricity by the rotation of propeller like blades that drives a generator through shafts and gears present within it. It is a rotating machine which converts kinetic energy from wind into mechanical energy and this mechanical energy is converted into electricity using a generator. 4FileVeladero 01.pngFigure 3 Wind Turbine in craggy Area 3HistoryA wind turbine is a machine which extracts energy from wind to generate electricity by the rotation of propeller like blades that drives a generator through shafts and gears present within it (Britannica, 2011). It is a rotating machine which converts kinetic energy from wind into mechanical energy and this mechanical energy is converted into electricity using a generator.Since a ncient times, man has tackle the force-out of the wind to provide motive power for transportation. Likewise, the technique of detrition grain between stones to produce flour is similarly ancient, and widespread. Where and when these two came unitedly in the first place is unknow, exclusively a likely scenario suggests a Iranian origin, from where the knowledge spread back into marriageern Europe as a result of the Crusades. 4 Since the Persian mills were quite unlike the early European designs it seems just as likely that the adaptation of wind as a power source was independently discovered in Europe. Of product line wind was not the first non-human power source applied to the task of grinding corn as it was preceded by both animal power, and in all probability by water power.European millwrights became lavishlyly deft craftsmen, growth the technology tremendously and as Europeans pot off colonizing the going of the globe, windmills spread throughout the world. The bas ics of windmill design take on those reinforced by the British, who developed many advanced control mechanisms over the centuries, and the Dutch who used windmills extensively to pump water and for industrial uses, as sanitary as to grind grain. 5As steam power developed, the uncertain power of the wind became less and less economic, and we are left nowadays with a tiny fraction of the elegant structures that once extracted power from the wind. These remaining windmills, seen all over the world, are a historic reminder of a past technological age. A number of mills put one across been oddmentored either visually or in some cases back to full working order. However the promise of widespread power from the wind lives on both in the form of wind turbines producing electricity, and in the form of gloomy scale wind pumps often erectly low-tech introductions still used extensively in the world of agriculture. 2FileWind turbine 1888 Charles B hasten.jpgFigure 4 An old wind stir4Wi nd world power in AfghanistanWind power has been used for much(prenominal) than 2000 socio-economic classs and the first windmill used for mechanical purposes was build in Afghanistan in the 7th Century. This was a good axis windmill with orthogonal shaped blades which was six to twelve sails covered in reed lusterlessness and was used to grind corn and drawing water.windmill39Figure 5 historic wind mill in Afghanistan 1Wind Power in Britain leaven of windmills in England dates from the 12th cytosine, with earlier references to mills generally held to be talk of the town about either animal or water powered mills. The cardinalteenth and 15th centuries provide evidence of what the early mills looked like with illustrations in diverse media such as memorial brasses, stained glass, and wood carvings, as well as the anticipate manuscript disks. These early illustrations all showed the simple all wooden post mill structure. The first illustration was shown in the late 1270 A.D which was a four bladed mill mounted on a central post. This was known as the post mill and was already a fair technologically advanced frame-up as compared to the Persian mills. These mills used wooden gears for the motion of the horizontal shaft to vertical bunkment to turn a grind stone. 4Wind Power in HollandAs early as 1390 the Dutch set out to right a design known as the tug mill. This was truly a standard post mill affixed to the top of a multi story column with separate floors devoted to grindinggrain, removing chaff, storing grain and living lodge for the wind-smith and his family. Both the post mill as well as the tower mill designs had to be adjusted according to the wind manually. This was done by pushing a cock-a-hoop lever at the back of the mill. withal optimizing the windmill energy and power outturn plus protecting the mill from damage by furling the rotor coil sails during storms was the main job of the wind-smith. 1Improvement in the design of the Wind m illA primary improvement in the design of the European mills was the use of sails that generated slick lift. This feature improved the rotor efficiency as compared to the Persian mills by allowing an emergence in rotor speed and hence which resulted in superior grinding and pumping action.5The process of perfecting the windmill as well as making additive improvements towards its efficiency took 500 years. By the time the process was immaculate the windmill sails had major features which were recognised by modern designers as being significant to the performance of modern wind turbine blades. Some models likewise featured aerodynamic brakes, spoilers, and flaps.windmillFigure 6 Mid twentieth Century wind generator 4While continuing well into the nineteenth century the use of large tower mills declined with the increased use of steam engines. The next mensuration in the development of wind power occurred many thousands of miles to the west. 1Wind Power in the regular armyFor hundreds of years the most important application of windmills at the subsistence level has been mechanical water pumping. This was done using relatively little systems with rotor diameters of one to several meters. These systems were perfected in the United States during the19th century. It initiated with the introduction of Halladay windmill in 1854, and continuing to the Aermotor and Dempster designs. 4The most significant modification of the American fan shaped windmill was the development of steel blades in 1870. These could be made lighter and worked into more efficient shapes. But, they worked so well that their high speed required a reduction in gear to turn the standard reciprocal pumps at the required speed. 1 In the late 19th century, advancement was made to the original design and a new casing of wind mill known as the multi-blade windmill was manufactured. This design was used in the first large windmill in order to generate electricity.Wind Power in DenmarkPoul la Cou r was the pioneer of electricity generating wind turbines and he published a journal found on wind power during the same year. Also it was reported that by 1918 around one hundred twenty local utilities in Denmark had a wind turbine. The approximated size was from 20 to 35 kW. At that time the wind turbines covered 3 percent of danish electricity consumption and Danish interest in wind power increased at a high rate. 4During the World War, the Danish engineers built a number of two as well as terce bladed wind turbines although their concept is a three bladed machine. This event of turbines was used in areas usually establish on a wind-diesel setup which ran the electricity supply system. The systems used designs focused on DC (direct current) generators to revenge their requires barely in 1951 these DC generators were replaced with AC (alternating current) generators and therefore became the siemens wind turbine to generate AC. 5In 1980, Christian Riisager, built a small 2 2 kW wind turbine in his back yard using an earlier design known as the Gedser Wind Turbine (three bladed wind turbine). His turbine design became a success within households around Denmark and this success gave the present day Danish wind turbine designers an inspiration. 3 This inspiration led them to design all their wind turbines and this trend started from 1980 to the present day. A new generation of wind turbines was developed in 1981 and that became a technological breakthrough for modern wind turbines throughout the world.The serial manufacturing of wind turbines started and Danish manufacturers had much more of a track record than companies and their individual countries. Another thing to note is that California, which is one of the biggest wind heightens in the world, has about half of the wind turbines of Danish origin.twentieth Century Developments and Modern Wind TurbinesIn the past, the Dutch refined the windmill and adapted it for draining lakes and marshes and when settlers took this technology to the New World in the late 19th century, they began using windmills to pump water for farms and ranches, and later, to generate electricity for homes and sedulousness. 520th century was the time when windmills were actually recognised as Wind Turbines. Across the plains they were used to pump water as well as to generate electricity but at the same time as new methods of utilising wind energy were being introduced this trend gradually spread around the world.windmillFigure 7 Evolution of Windmill programme in 20th CenturyAt present the modern wind turbines are based on three blades using AC generators and getup is rated in mega watts (MW) or giga watts (GW). Some modern wind turbines are based on four to five blades and they are being used on both AC and DC. The governing body is the World Wind Energy Association and as per their annual World Energy Report, a integrality number of 76 countries in the world are using wind energy for mercenary purp oses. The main countries that widely use wind turbines at present include USA, UK, France, Germany, Australia, Denmark, Spain and chinaware. The countries that recently became users of wind energy resources are India, Pakistan and Turkey. These figures suggest an increase in use of high output wind turbines but currently miniskirt or small wind turbines are available and are being used where they pee an output power requirement ranging from a fewer watts (W) to kilo watts (kW). 3For a long time individual wind turbines were installed to support single households but now this idea has been advanced to improve the usage of this energy. Nowadays, wind turbines are installed on a large area whitethorn that be land or sea. The output is connected to a storage-battery grid system. Many countries have installed a number of wind farms across their plains and fitted windy locations but the largest on-land wind farm is known as Roscoe Wind Farm and is located in Texas, USA. This wind fa rm comprises of 627 wind turbines and a total installed subject of 781.5 MW and provides enough power for more than 250,000 average Texan homes. It is located about 200 miles west of Fort Worth, and covers nearly 100,000acres. The help largest wind farm is also located in Texas, USA. This wind farm is known as the Horse Hallow Wind Energy nub and has 421 wind turbines that generate a total electrical condenser of 735 MW. Out of the total 421, 291 of them are 1.5 MW wind turbines and 130 are 2.3 MW wind turbines. The turbines are own by Florida Power Light and the company operates 46 other wind farms throughout the US. 41-rosco-wind-farmFigure 8 Wind farm in England 5The largest Off-shore wind farm in the world is the Thanet wind farm. It is located in the North Sea about 7 miles off the coast of Kent, England. The wind farm has 100 turbines and has the capability produce enough energy a year to power more than 200,000 homes. The second largest onshore wind farm is called Horns Rev 2 and is located on Horns Reef in a shallow area off the westernmost point of Denmark. Horns Rev 2 make up of 91, Siemens wind turbines with a total generating capacity of 209MW. 7Thanet-wind-farm-opened-006Figure 9 Off shore wind farm along the coast of Kent (England) 5Future of Wind TurbinesIt is predicted that wind energy will be the most live effective source of electrical power in the near future. A good part of this prediction has been proven during the current energy rush so its reliability can easily be visualised for future. late improvements in wind turbines have shown that the trends which have led to the dramatic come down in the cost of wind energy are set to continue. Countries all over the world are setting their targets for wind power and it is estimated that about 22,000 MW, in the form of 40,000 wind turbines will be installed in the next 10 years. Europe is the hub of this global business and will continue to be as around six companies supply over half o f the worlds wind turbines. 6As more and more countries start using this reliable source of electricity, master plans are being set for the future. Already the USA, China, Germany and UK have set targets to build nevertheless wind farms and each one bigger than the other. As USA has currently the biggest on-land wind farms in the world, they would like to maintain that in the future. Around six wind farms are planned within the USA for the next 15 years and they should be able to maintain the record of largest wind farms in the world. One of the planned wind farms is the Alta Wind Energy Centre in the Mojave Desert California. This farm will have more than 600 wind turbines and when it is completed this will have the capacity to generate 1,550 MW of energy which is double the capacity of the largest existing wind energy farm. USA has no off-shore wind farm but their future plans include the installation and usage of this setup. 620100730-193513-pic-977799504Figure 10 Wind farm in C hina 6China also plans to increase their usage of wind energy and they are also intricate in future projects as well as developing wind farms. One of their future aspirations is the under construction Gansu Wind Farm. It has been estimated that whencompleted by 2020 and would have the output capacity of 10 Giga watt (GW). They also plan to reach 100 GW overall wind energy output by 2020 as other future wind farms are under construction. By that time it could be the largest capacity wind farm in the world.In the UK, wind energy is being used extensively and more plans have been set in place for the future. They have more plans to build off-shore wind farms instead of on-land ones as well as to increase the capacity of current setup. Another master plan is to build a wind turbine factory, run by the German giant company Siemens and is expected to complete by 2015.Germany is also involved in certain future projects as their current setup is highly dependable on wind farms. Currently a round 20,301 on-land wind turbines are located in the German federal areas and the country has plans to build more wind turbine farms and reach a high capacity by 2020.They are planning more offshore wind energy as well and predict a capacity of about 10.000 MW by 2020. Most of these off-shore farms will be erected up to 20-60 km away from the coastline.energy-frozen-fish-wind-farms-turbines_18081_600x450Figure 11 Modern wind farm in Germany 2Types of Wind TurbinesSince the development of the wind turbines, numerous designs have been introduced and used worldwide. The difference in these designs was on the basis of size, output power and shape of the wind turbine. The largest wind turbine and the one with the most individual output power up to date is the Enercon-126. Its rated output is about 7 MW and its rotor diameter is 126 meters.Wind turbines can be divided into two basic types and this is determined by the way the turbine revolves. One is the horizontal axis wind turbine and is most usually used (FIG- 12) while the other one is the vertical axis wind turbines (FIG-13). 3http//www.ecotownforleicestershire.coop/assets/images/masterplanImages/energyreportVertical-axis-wind-turbine.jpghttp//www.aboutgenerator.com/wp-content/up agitates/2010/07/how-to-build-a-wind-turbine.jpgFIG 12 9 FIG 13 9Horizontal axis wind turbine (HAWT) is the common style wind turbine which has a design similar to that of a wind mill and has blades that look like a propeller that spin on the horizontal axis. The main rotor shaft and electrical generator are at the top of the tower and are pointed into the wind. Small turbines are pointed by a simple wind vane placed unanimous with the rotor (blades), while large turbines generally use a wind sensor coupled with a servo motor. 9Since a tower produces uplift behind it hence the turbine is usually pointed upwind of the tower. Wind turbine blades are made stiff to prevent the blades from being pushed into the tower by high winds. S ince the turbulency leads to fatigue failures so most HAWTs are upwind machines. Since the blades always move perpendicularly to the wind they help receive power through the building block rotation. 9Small wind turbines are being used extensively in off-grid systems like street lighting, phone booths, lighting up parking areas and existence mobile chargers. These wind turbines are usually used with another device such as solar panels and are part of a setup. They are light, easy to install and reliable in all wind conditions.Green-Column2Figure 14 Green Column 1Vertical axis wind turbine (VAWT) is when the main rotor shaft is arranged vertically. The main advantage of this arrangement is that the wind turbine does not need to be pointed into the wind and can be most reliable on sites where the wind direction is highly variable or turbulent.In a VAWT the generator and other main components can be placed near the establish so the tower does not need to support it. It is difficult to mount these type of turbines on towers so they are often installed nearer to the base on which they rest, such as the ground or a building rooftop. The wind speed is slower at a lower altitude which means less wind energy is available so air flow near the ground and other objects can create turbulent flow resulting in issues like vibration. However, when a turbine is mounted on a rooftop, the building will generally redirect the wind over the roof and this doubles the wind speed at the turbine. 9There are two subtypes of VAWTDarrieus wind turbines are commonly called eggwhisk turbines as they look like an eggbeater. They are highly efficient but produce large ripple and cyclic stress on the tower which will contribute towards low reliability. They generally require some outdoor(a) power source to start turning because the starting torque is precise low. The torque ripple is reduced by using three or more blades which will result in a higher solid for the turbine rotor. Solidi ty is measured by blade area over the rotor area and newer models of this type of turbines are not held up by guy-wires but have an external superstructure connected to the top.Savonius wind turbines is a drag type turbine and are commonly used in cases of high reliability in things such as ventilation systems. Because they are a drag type turbine they are less efficient than a common HAWT but they are excellent in areas of turbulent wind and self starting.Wind turbine manufacturersAs wind energy has become a widely used concept, a number of companies have introduced their designs and perfected them. The most popular companies around today are Enercon (Germany), Vestas (Denmark), GE Wind Energy (USA), Siemens Wind Power (Germany), RE Power (Germany), Sinovel (China), Goldwind (China) and Gamesa (Spain).All these companies are famous for manufacturing as per their own HAWT designs and their systems are being used worldwide. Enercon, Germany based company, is the only company to have made the most powerful and largest wind turbine in the world known as Enercon-126. They continue to work on more ideas and increase the output capability of their wind turbine. On the other hand Vestas which is a Denmark based company is the biggest manufacturer of wind turbines in the world. Most of their wind turbines and installed in Europe as well as USA and their orders keep on increasing day by day as per demand and dependance on wind energy. It was stated that most of the designs from other companies are actually modifications to the original design created by Vestas and this influence can be seen in their systems. 10Other companies like GE Wind Energy and Siemens have made major contributions in the manufacturing and enhancing the capabilities of wind turbines of the present age and they are looking forward to the future for more opportunities to make themselves well known within the industry. 10Small sized wind turbines made their way into the industry due to the need for smaller and off-grid systems. Marlec Renewable Power is one of the companies that initiated this type of wind turbines and they came up with the idea named Rutland wind turbines. Rutland wind turbines are being commonly used in UK and Europe these days but further international use has been planned due to the interest shown by international investors. Rutland wind turbines have current designs using 3 to 6 blades but they are mini versions of HAWT and no VAWT designs have been introduced up to date. They have generally been used in off-grid systems and add a good combination to the milieu surrounded by wind turbines. 10Disadvantages of wind turbinesThe strength of the wind is not constant and it varies from zero to storm force. Which means that wind turbines will not generate the same make out of electricity all the time as well as there will be times when they generate no electricity at all.Many hatful feel that the countryside should be left untouched so the landscape could b e left in its natural form.Wind turbines are noisy as each one can generate the same level of noise as a family car at very high speed.People see large wind turbines as unattractive structures and not pleasant to look at. They could impair the countryside and might seem a horrible sight.Wind turbine construction can be very high-priced and costly to the surrounding wildlife during the building and installation process.In some areas of wind farm developments birds have been found departed around the base of turbines.Many people think wind turbines are a great idea, yet a large proportion of these people would oppose a wind farm development close to their home due to their land price reduction as well as noise pollution.Modeling of wind energy and generatorIn order to develop the prototype circuit in the laboratory, wind energy has to be simulated along with the generator. At first it was headstrong to use a 12 volt manual generator which can be operated by hand to output 12v so t hat this can be fed for the rest of the circuitry. A cheap 12v Generator could not be found, very expensive models were available but it was decided not to buy them as it will increase the cost of the product dramatically. Finally, it was agreed that the 12v DC from the power supply will be used to simulate the output of the wind generator.MethodMethod section of this report throws light on the wind power battery charger circuit used and also explains different techniques used in order to build the prototype.Method section of this report can be sub divided in the following main categories1 Research regarding components used in this project2 Circuit Design and Explanation3 Circuit ConstructionResearch regarding components used in this projectAt first it was decided to develop a battery management circuit from scratch by using analogue circuitry, dollar converter and 555 timer or microcontroller in order to switch the deplumate converter, but after some research and investigation it was found that there are some specialized ICs available which can be used for managing battery charging circuits.Different verities of battery management IC were available from liner technologies, Analogue devices, microchip and National Instruments but selection criteria for the IC involved a DIP package for easy prototyping, operating temperature range of -40 to +85, supply potential drop rating of up to 18v and cheap in price. after(prenominal) some search through different vendor websites, LTC1042 seemed to be a suitable candidate for this particular application. After mutual consent it was decided to use LTC1042 as main charge management IC in this project.Circuit Design and ExplanationLooking through the LTC1042 datasheet, it was discovered that this IC can be adopted for the needs of renewable energy resources and can easily manage different load types based on the amount of energy being produced at one particular time.Application notes of LTC1042 suggested a circuit for u sing this IC for managing wind powered battery charger. In order to prove the concept of the system, it is decided to build this circuit and experiment with it.Chosen CircuitThe circuit to be built is shown in the diagram belowFigure 15 Wind Powered Battery Charger CircuitCircuit ExplanationThis circuit behaves in a latching manner, i.e. depending upon the voltage being generated by the wind generator different type of load will be on and off. LTC1042 is a CMOS window and manages the turning on and turning off of different loads.This circuit contains two batteries and one load, its exertion is summarized in the following lines1 If the generator output voltage is below 13.8v, charge regulator circuit is active and Ni-Cad battery will

Trends in Graduate Employment Opportunities

Trends in Graduate Employment OpportunitiesINTRODUCTIONTo be employed is to be at risk, to be employ commensurate is to be bear (Hawkins 1999).Today profession is no longer a form of security system because of the ever changing nature of the thrift, the progress toplace and the changing needs of employers. If graduates atomic number 18 to attain physical exertion, retain their positions in the work place and move up the c atomic number 18er ladder, they need to continuously cave in themselves professionally and build on their employability skills they need to have a plan.This report interrogationes graduate opportunities in the strain administration/Management sector. Business administration is utilize as a synonym for focusing. Administration is frequently seen as paperwork and form-filing, but it reaches much than astray than that to encompass the coordination of all procedures that en adequate to(p) a product or swear out(p) to be delivered, to aimher with keepi ng of records that asshole be checked to expose errors or opportunities for improvement. (Business Administration 2009).This sector was chosen because the looker is pursuing a Bachelor of arts degree in Business Administration and aspires to chi open firee exactly what is required to become employable.The inquiryer plans to fulfill this aspiration by first identifying key put downing regarding this sector in terms of ecumenic employment trends and graduate opportunities, the employability skills establishments expect from graduates and the enlisting and selection orders utilise by organisations. The query methods used to accomplish the former is explained in detail in the methodology variance of this report.Second, the findings of the question in terms of the employability skills atomic number 18 thence matched a murderst a personal epitome of the researcher and a gap analysis and cargoner challenge plan formulated.Finally the report concludes with the researcher r eflecting on what was learnt from the research get laid and the usefulness of the go action plan for the future day.occupational RESEARCHThis areaitioning of the report come throughs a factual reflection of the findings from the research conducted on graduate opportunities in the Business administration/ steering sector. scathe of ReferenceThis report researches graduate opportunities in the Business administration/management sector. Through a process of factual and personal reflection it provides information on how can graduates in this field of operations can increase their employability and tradeability done personal and professional development. The report is required to show severalise of the research used for reflection.MethodologyThis report is based on secondary research carried out among February and March 2011. The researcher aims to gather factual with-it information on graduate opportunities in the Business administration/management sector in the following ar gonasGeneral employment trends.Opportunities for modern graduates.The skills cognition and dumbfound required from graduates by employers.How graduates argon recruited and selected.The researcher knack out to use the case study method for research as this method allows the researcher to investigate a contemporary phenomenon within its real-life context when the boundaries between phenomenon and context are not clearly evident, and in which multiple sources of evidence are used (Yin, 1989). However due to difficulties faced in finish interviews with companies chosen for the case studies and the coarse number of incomplete questionnaires returned, the researcher had no choice but to complete the report with the use of secondary research only. Using the limited information attained would have compromised the accuracy, reliability and lustiness of the report. Time constraints pr stock-stillted the researcher from setting up interviews with other companies and it would have been un ethical for the researcher to force respondents to complete the questionnaire or to fabricate information.Thus a wide range of secondary research from academic sources were used much(prenominal) as journal articles, books, craft databases, parvenuespapers, ready iticrafts and vocation websites and general job and specialist websites.For general employment trends in this sector not only articles were used but up to date statistics as well from reliable sources (The fall in States Depart of crunch, Bureau of Statistics) to maintain accuracy. tuition for employment opportunities were found in general in job and career websites.The summary provided on the skills, retireledge and experience required from graduates and the recruitment and selection methods was based on online research from sestet organisations in several(predicate) sectors ranging from large enterprises to not for profit organisations. Although connection websites provided the mass of information for this section they were not the only source used.The researcher is alive(predicate) of the limitations of secondary research such(prenominal)(prenominal) as inaccuracy and out of date information, but the researcher attempted to counteract this by using reliable sources such as journals and databases and sites that provided up to date information and national statistics.Main FindingsThis section of the report provides key information regarding the Business administration/management sector. Whether the diligence is expanding or contracting is vital information for graduates as this directly affects the involve for jobs in fields within the sector. With this be intimateledge graduates will be able to tally informed decisions, for example, to choose a career in a field that is maturation and not declining. In addition, graduates will be able to reflect on their knowledge, skills and experience after gaining information on the employability skills employers are under submiting, there by providing them the probability for professional development in areas needed. Furthermore, being true of the recruitment and selection intrusts employed by organisations allows graduates to prepare themselves to get the job they desire.General employment trends in this sectorAdministration and Management are extremely broad areas and graduates seeking employment in this sector can get jobs in the untroubleds-producing industries such as manufacturing and construction or the service-providing industries such as health care, education and administrative and support run. let out section 2.2.2 page 9, figure 3 for a list of graduate jobs in this sector. harmonise to the United States subdivision of Labor, Bureau of Labor Statistics, employment in goods-producing industries has decompositiond since the 1990s. Although oerall employment is expected to change little, projected growth among goods-producing industries varies considerably. See Figure 1.This is in contrast to servi ce producing industries the shift in the U.S. economy away from goods-producing in favor of service-providing is expected to continue. Service-providing industries are anticipated to amaze approximately 14.5 million new wage and salary jobs. (United States Department of Labor 2010). See Figure 2. consort to these industry trends, graduates who choose jobs in the maturation service industry are expected to have a long-run career as opposed to those in goods- producing industry.Industry growth or decline will affect the demand for occupations. Thus if an industry is growing for example the health and services industry then graduates who gain employment in this industry will be able to move up the career ladder from perhaps a junior health executive director to a senior health administrator. However if the manufacturing sector is on the decline then entering this industry as a junior performance manager may not be wise as the placement may be short lived through retrenchment or l ayoffs.Statistics make kn fuck off in that employment in management occupations project to grow slowly over the projection period 2008-18, increasing by 5 percent, an addition of 454,300 new jobs and office and administrative support occupations expect to grow by 8 percent, adding 1.8 million new jobs by 2018. (United states Department of Labor 2010).Another recent trend is the demand for graduates from Small and spiritualist Sized Enterprises (SMEs). There are an estimated 4.8 million SMEs in the United Kingdom (UK) employing 23.1 million mass with a combined annual turnover of 3000 billion. (Kewin et al 2010). Thus, graduates who do not deal to work in large unified have an option and opportunity to work in a different atmosphere as compared to the past. alike in recent socio-economic classs, there has been an increased interest in employability skills by employers. A degree alone is not enough. Employers are looking for more than scantily technical skills and knowledge of a degree discipline. They particularly lever skills such as communication, aggroup working and problem-solving.(Jones, D 2005).In addition, the methods used to advertise jobs are overly changing. In the past, it was common for advertisements to be in newspapers, career magazines, career services under universities and spread by watchword of mouth. However, due to increased engine room organisations are putting advertisements on employment websites and using online recruitment agencies. By the click of a button, graduates can approach shot and explore a range on different job opportunities and career information locally and globally as well as sacrifice online for jobs instead of the handed-down way by post or hand delivery.Furthermore, there are changes in the methods used for graduate recruitment and selection. Socio economical and political changes as well as developments in information applied science have all led to the introduction of new and more modern methods of r ecruitment and selection. (Sackett Lievens 2008 cited in Brianne, M 2008).The roles employers expect graduates to perform are also changing. For example, earlier, the role of the secretary was limited to taking notes from their heads, typing and storing information. However, with the advent of technology in companies and offices, the secretary duties have extended to things that are for the professional and managerial staff. (Kartha, D 2010).Additionally, because the world is now becoming a global market place some occupations require graduates to have a second speech as they will be communicating with clients worldwide, for example a gross sales manager or executive administrative assistants and secretaries.Graduates may have certain skills, interests and objectives, however, they need to take into consideration these industries and employment trends so they can make informed decisions regarding their career choice. The following section will now debunk the range of opportuniti es getable to graduates.2.3.2 Opportunities for recent graduatesAll organisations, large or slight and across all sectors need administrators, managers and administrative support staff. Thus, graduates can get jobs in the public, private and not for profit sectors, in large corporate and in SMEs. In fact, if graduates do not want to choose the traditional graduate management route self-employment, franchising or branch management could be what they are looking for. Fig 3 shows a list of careers available in this sector.Figure 3. SourceUniversity travel Center. KUCareerHawk.comThe role graduates perform would calculate on the organization they are working for in terms of the sector, the organization structure and culture and the attractership styles within the organization. For example in large organisations graduates may perform routine structured roles in a special(prenominal) area of the job example finance as compared to Small and Medium sized Enterprise (SMEs) who duties m ay be unstructured and graduates will be involved in all aspects of the organisations work.Employers advertise graduate employment opportunities in newspapers, career magazines and through university career services. However, the most popular form of announce today is on company and university websites, online recruitment agencies and graduate jobs and career services websites such as targetjobs.com.The next section provides information active the employability skills employers seek from graduates.2.3.3 The skills, knowledge and experience requiredLeaving university with a Bachelor Arts degree in Business administration is important in attaining a job in the graduate employment market, however it is not enough. According to Carl Gilleard Chief Executive, Association of Graduate Recruiters twenty-first century graduates need to attest to employers that they can hit the ground running. In addition to working effortful to gain a good degree, students should engage in extracurricula r activities and obtain work experience in order to develop skills that will make them better prepared for the world of work. It is also important for students to become self- cognisant and develop the confidence to market themselves effectively when the time comes to apply for jobs. (target jobs.com) away from the formal qualifications of a degree which was strongly desired by five-spot of the six organisations researched employers required graduates to have at least one category experience in the field. In terms of skills, commercial knowingness skills, battalion skills, enthusiasm and motivation and communication skills were deemed to be the most important.The section that follows provide information on recruitment and selection processes used by organisations.2.3.4 How graduates are selectedGraduate recruitment and selection is a process of searching for and obtaining emf job applicants from graduates in sufficient quantity and quality so that employers can select the most suitable candidates to fill in their job vacancies .(Beardwell et al., 2004). In practice there is no one best way or commonly agreed procedure on how to recruit and select graduates because different employers have different recruitment and selection methods depending on their operations, size and needs. (Sackett and Lievens, 2008).According to the employers in the organisations researched they preferred to recruit graduates through online methods, example via milkround. Other methods sometimes used are recruitment brochures, recruitment fairs this method was very popular, recruitment agencies, and to a lesser extent newspapers and magazines.The selection process has changed as organisations are not only using interviews as a means of selecting individuals. In order for individuals to display their knowledge, skills and abilities the use of assessment centers was most popular in large organisations. The smaller organisations that do not have assessment centers set up used aptitude and psychometric tests.PERSONAL REFLECTIONThis section of the report is based on a personal analysis which is matched against the findings of the research. A career action plan is then developed to for future use. individualised AnalysisDrew and Bingham (2001) define reflection as looking support on experience and making gumption of it to identify what to do in the future. The following skills were indentified after I did a personal reflection.Communication skillsI enjoy working with people of all ages and backgrounds. At work I have experience in training On the Job Trainees( OJTs) via workshops and in my second year at the University of the West Indies I coached students on a weekly basis for two modules for a period of six months. I communicate with the public on a daily basis and this has enabled me to modify my skill in this area.Presentation SkillsI have experience in giving presentations to small groups in the first two years at university as some of the modules were partly presentation based. Assignment based presentations has allowed me to develop the use of clear and concise language, good planning and organisation and good interaction with the audience.Other SkillsMy work experience throughout the years enabled me to gain extensive experience in the area of customer service. My first part time job in a fast food eating house as a customer service worker has developed my team building skills. I was promoted to team leader in one year time and I was awarded for having outstanding enthusiausm and motivation skills. As a writing table I was involved in the preparation of correspondence, reports, plans and budgets. Multitasking was a skill I learnt as a telephone operator whereby I handled six next lines with 40 extensions transferring calls to department heads. The position I currently hold requires me to work in a fast paced, hectic environment so I am capable of handling multiple tasks at once. I know how to prioritize job assignments, work indepe ndently and interdependently and resolve problems on my own as well as part of a team. I am very organized and detailed oriented. I am the project leader for all incoming projects because I possess good motivation skills and organisational skillsCV Covering LetterAppendix is a cover letter and CV prepared in response to a job nullity recently advertised in the Public service sector as a Business Operations Assistant.Gap AnalysisAfter conducting research and conducting a personal analysis I have matched all the skills needed excepting commercial certified(p)ness skills. I have plenty experience in the Administration field and I am in the process of obtaining my degree. unconnected from theses knowledge skills and experience, I have hands on experience in typing but lack a formal authentication, which are oftentimes requested by organisations.Lack of education in terms of possessing a foreign language has continuously restricted me from taking advantage of opportunities I woul d like to apply for. Many times I see a job advertised and I have all the qualification and experience except the ability to speak a foreign languageCareer Action PlanThe definition most often used for technical Awareness is by Christopher Stoakes in his excellent book All You claim to Know about Commercial Awareness. He statesAt heart, commercial awareness is about being able to talk to clients, finding out what they want, wherefore they want it, what they will do with it and what they are prepared to pay, and then delivering it in the way they want. To do that you need to understand how organisations work, the issues they face and the role of people within them.To increase my commercial awareness skills I qualify to read not only the newspaper articles but also published business magazines as well. When applying for jobs I also intend to research the company and even prepare a SWOT analysis of the company for two reasons. maiden to let the interviewer know that I have extensi ve knowledge of the company enabling me a better chance of getting the job and second, to know if the company is one I would really like to work for. Furthermore, I intend to buy the book All You Need to Know about Commercial Awareness by Christopher Stoakes it is selling on Amazon for just $24.27.I have located a business school that offers a short var. on typing. The duration is 3 months part time. I intend to take this course as a next measuring stick to developing my skills. Having achieved this will better position me to apply for those jobs that require the certificate in typing.Spanish and French are two popular foreign languages, however because I live in the Caribbean Spanish is more often requested by employers. A local university offers introductory intermediate and advance(a) levels in Spanish courses. The total duration for all three separate is one year part time. As a part of the course the university in the final stage takes a trip to a Spanish speaking country t o give students practical experience in the field in real live settings. I also intend to take this course. Appendix 3 is a summary of a career action plan I developed.CONCLUSIONHaving completed this exercise has made me aware of available opportunities I never knew existed in this sector. Having knowledge of the recent trends and developments and future trends in this sector will now enable me to make more informed decisions when applying for positions in the job market.Also I was not aware of commercial awareness skills until I did this report, I never even knew that a skill like this existed. Furthermore identifying my strong and weak areas gave me a sense of self fulfillment and now I know exactly what travel I had to take to develop them.Drawing up a career action plan allows me to see exactly how long it will take me to achieve my career goals and I am enthusiastic to start. I intend to continuously keep up to date with trends in the sector and always keep updating my career action plan. I am extremely happy that I did this module. It really helped me personally and professionally.REFERENCESBeardwell, I., Holden, L. and Claydon, T.
