Judul: Dampak Kebijakan Antidumping Tariff dan Free Trade Agreement Terhadap Permintaan Impor Udang Amerika Serikat
Abstrak: The United States became the major shrimp importer caused by high consumption and demand of shrimp import. Shrimp industry domestic suffered by shrimp import therefore the government set the trade policies such as Antidumping Tariff and Free Trade Agreement. The purpose of this study is to analyze the impact of the United States Antidumping Tariff and Free Trade Agreement. Revealed Comparative Advantage (RCA) and Gravity Model approach was used in the analysis. The result is Indonesia has the highest RCA compared other exporters. Based on the theory, Antidumping Tariff has decreased shrimp import demand. Free Trade Agreement has decreased shrimp import demand however it is not relevant with theory.

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: Nanokristalin Pirit (FeS2) sebagai Material Semikonduktor Fotovoltaik.
Abstrak: Teknologi fotovoltaik adalah suatu proses yang dapat mengubah sinar matahari menjadi energi listrik dengan media semikonduktor. Penggunaan sel surya untuk fotovoltaik hanya dapat mengonversi radiasi matahari menjadi energi listrik kurang dari 20%. Efisiensi akan meningkat ketika material semikonduktor untuk fotovoltaik dibuat menjadi ukuran nano. Pirit merupakan salah satu material semikonduktor fotovoltaik yang memiliki energi pita celah (Eg) dalam kisaran 0.8–0.95 eV. Energi pita celah tersebut terbukti meningkat ketika disintesis dengan metode hidrotermal menggunakan beragam molar [S]:[Fe] pada suhu 200 °C dalam 24 jam. Nilai energi pita celah yang dihasilkan adalah 1.58–2.073 eV. Ukuran nanokristalin pirit yang dihasilkan berada pada kisaran 21.04–58.77 nm menurut data Particle Size Analyzer. Besarnya ukuran nanokristal pirit yang tumbuh kurang dari 50 nm merupakan poin penting untuk aplikasi fotovoltaik.
