Judul: Comparative analysis of monetary transmission channel in indonesia
Abstrak: Penelitian ini bertujuan untuk membandingkan kekuatan relatif dari masing-masing jalur mekanisme transmisi kebijakan moneter di Indonesia. Metode analisis yang digunakan dalam penelitian ini adalah pendekatan ekonometrika dengan model Vector Error Correction Model (VECM). Penelitian ini menggunakan data time series bulanan tahun 2004:1 sampai 2013:10. Hasil menunjukkan bahwa pada jangka panjang, suku bunga pasar uang antarbank (PUAB) sebagai sasaran operasional kebijakan moneter tidak mempengaruhi outputmaupun inflasi. Berdasarkan hasil analisis IRF menunjukkan bahwa tidak adanya kesesuaian teori pada respon masing-masing variabel jika terdapat guncangan pada suku bunga pasar uang antarbank (PUAB), kecuali variabel nilai tukar dan variabel kredit. Hasil analisis FEVD menujukkan bahwa nilai tukar merupakan jalur yang paling memengaruhi output di Indonesia. Jalur kredit merupakan jalur yang paling memengaruhi inflasi di Indonesia., This study aims to compare the relative strength of each channel of monetary transmission mechanism in Indonesia. Methods of analysis used in this study is the Vector model Error Correction Model (VECM). This study use monthly time series data (2004): 1: 10 until 2013. The results show that in the long run, the interbank money market interest rates (PUAB) as the operational target of monetary policy does not affect the output and inflation. Based on the results of the IRF analysis show that the response of each variable if there are shocks on the interbank money market interest rates (PUAB) is not suitable with the theory, unless the exchange rates variable and credit variable. FEVD analysis results shows that the exchange rate channel and credit channel have highest relative importance to explain the output and inflation in Indonesia.

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
