Judul: Pembuatan dan Karakterisasi Prototipe Sel Surya Nanokristal n-TiO2/Dye/p-CuSCN
Abstrak: Dengan metode casting dan perlakuan annealing, dapat dibuat lapisan nanokristal semikonduktor TiO, pada substrat Transparant Conductive Oxide (TCO). Penambahan dye Methylviolet Thiocianate (MVSCN) dan lapisan CuSCN pada TiO, tersebut menghasilkan sel surya n-TiO,ldye/p-CuSCN yang dapat menyerap foton dan mengubahnya menjadi energi listrik.

Judul: Pembuatan Dan Karakterisasi Prototipe Sel Surya TIo, Tersensitisasi Dye Organik Sintesis
Abstrak: Oleh karena sumber energi minyak bumi yang keberadaannya semakin menipis di alam ini maka dicari sumber energi altematifuntuk <lapat digunakan dalam berbagai kebutuhan hidup manusia. Salah satu aitematif yang dilakukan adalah dengan mengkonversi langsung energi cahaya dari malahari menjadi bentuk energi listrik dengan piranti yang disebut Sei Surya. Sel surya nanokristal tersensitisasi dikembangkan untuk menekan biaya pembuatan yang mahal serta peralatan produksi yang rumit. Sel Surya ini menggunakan prinsip yang sarna dengan proses fotosintesis alam. Sel ini merupakan aplikasi dad elektroda semikonduktor dye sensitizer pada jenis baru dari sel fotovoltaik. Foto elektroda dari sel fotovoltaik ini terdiri dad lapisan 1 0-20 ~m dari partikel Ti02 nanokristalin yang mengandung lapisan tunggal dari molekul dye teradsorbsi ; partikel dye ditopang pada substrat kaca konduksi transparan (TeO). Sel ini juga menggunakan larutan elektrolit 1"11)· dan elektroda counter karbon. Proses elektrokimia cahaya pada sel surya tersensitisasi dye membentuk siklus yang mengkonversi energi cahaya menjadi bentuk energi yang lebih berguna. Pada peneHtian kal

Judul: Amfibi sebagai satwa peliharaan: Ekspor, Impor dan Perdagangan Domestik
Abstrak: Indonesia has exported amphibian as frozen frog legs (listed since 1969 under fishery product) for consumption and live amphibian (listed since 1983 under reptilian class in forestry product) for pets. There are also live amphibian trading in local level i.e in markets and malls. This research aims to identify amphibian species exported and imported by investigating document from related administration and to identify amphibian species traded in domestic market by observation at Jakarta. Research is primarily conducted by processing quota data taken from Department of Forestry Republic of Indonesia database in Jakarta. Market observation was carried out in 18 locations (3 markets and 15 malls) in Jakarta. I carried out interview with trader and export business, which related to net trading live amphibians for pets. Respondent was choosen using snowball sampling manner. Name of species is written according to Iskandar & Coljin (2000). If there is no such record in the checklist (for example species are from outside Indonesia), then the species name is written according to Frost (2004). There are 56 species from eight families of wild amphibians that have pets quota between 1998-2008. Nineteen species was traded since 1983. The highest export quota is Litoria caerulea (21,37%). Allocation of highest catching quota is for BKSDA Jayapura (20,40%) and BKSDA Papua Barat (18,96%). Four species are included in IUCN Red List categories as vulnerable, among others are Limnonectes macrodon, Meristogenys jerboa, Nyctixalus margaritifer and Rhacophorus margaritifer. The number of amphibians that have export realization are 39 species. Two species of amphibian, Leptobrachium hasseltii and Rhacophorus margaritifer are amphibian species whose been known infected by chytrid fungus in the wild. The biggest species exported is Litoria caerulea (54,34%). Between 1983-1991, the biggest import amphibian for pets from Indonesia (66,13%) is Netherlands. Number of quota was relative stable in the last eight years, where as the number of export realization is more fluctuates. Amphibian species imported and re-exported between 1983-2008 come from Africa, South Asia, Malaysian, Archipelago Oceania, North America, Central America and South America. The number of pet amphibian species traded at domestic market is less than exported. Data showed that Indonesia imports 15 amphibian species between 1983-2008, However I found different species in the market that was unrecorded in the Ministry of Forestry data, which is the Fire Belly Salamander.
