Judul: Dampak subsidi suku bunga pinjaman terhadap ekspor udang Indonesia
Abstrak: Nowadays, shrimp becoming primary fisheries product of export activity. Growth of Indonesia shrimp trading had several issues both in domestic and international (export). Domestic market obstacles shrimp were supply continuity in frozen and prepared shrimp industry and also fisherman and fishery sellers at small and medium range typically difficult to got loan. International market obstacle happened because Indonesia shrimp product still not legalized related standard. The aims of this research were to analyzed factors that influenced in supply and demand of domestic market and export to United States of America and Japan related to the subsidy law affect toward supply demand and Indonesia shrimp export quantity.This research used time series data from 1989-2011. Indonesia shrimp tranding model built as simultan equation system and estimated by two stage least square (2SLS) method. Indonesia shrimp tranding spesification model divided into 32 equations (21 structural equations and 11 identity equations). Loan rate subsidy law will increasing shrimp production (fresh, frozen, prepared) that encourage shrimp export capacity from Indonesia to United States of America and Japan.

Judul: Dampak perubahan faktor ekonomi terhadap perdagangan udang Indonesia di pasar domestik dan international
Abstrak: Penelitian ini bertujuan untuk menganalisis: (1) faktor-faktor yang mempengaruhi produksi udang Indonesia, penawaran ekspor udang Indonesia dan negara pesaing utama ke negara-negara konsumen utama dan permintaan impor udang negara-negara konsumen utama; (2) dampak kebijakan pemerintah dan perubahan faktor ekonomi eksternal terhadap perdagangan udang di pasar domestik dan internasional serta distribusi kesejahteraan; dan (3) pangsa pasar udang Indonesia di pasar internasional. Penelitian ini menggunakan data time series periode 1974. - 1997, yang dikumpulkan dari publikasi resmi dari berbagai instansi nasional maupun internasional. Analisis menggunakan pendekatan ekonometrika dengan model persamaan simultan yang diduga dengan metode Two Stages Least Squares dan analisis pangsa pasar menggunakan model persamaan tunggal yang diduga dengan metode Ordinary Least Squares, dst

Judul: Sintesis dan Pencirian Natrium Titanat (Na2Ti2O4(OH)2) Berbahan Dasar Titanium Dioksida
Abstrak: TiO2 can be utilized as basic material for synthesis of sodium titanate (Na2Ti2O4(OH)2). This research was purposed to synthesize and characterize sodium titanate from TiO2 rutile powder as a basic material. Sodium titanate was synthesized by hydrothermal process at temperature 130 °C by mixing TiO2 rutile powder with 5 M and 10 M NaOH solution, then each was calcinated at temperature 700 °C. The energy dispersive X-ray analysis showed that sodium titanate has been successfully synthesized. This result was also supported by functional group analysis with Fourier transform infrared (FTIR) spectrofotometer showing the existence of Ti-O-Na vibration band at 989.42 cm-1. The formation of sodium titanate was depend on the reaction condition such as temperature, reaction time, and NaOH concentration. Scanning electron microscope image indicated that sodium titanate synthesized at 130 °C in 20 hours reaction time with 10 M NaOH had crystal size of 99.37 nm.
