Judul: Model Pengelolaan Perikanan Pelagis Kecil dan Demersal Berbasis Ekologi-Ekonomi di Pantai Utara Blanakan, Subang, Jawa Barat
Abstrak: Blanakan is one of coastal area in North of Java which have fisheries resources potential, some of them which have high production and important economics value are Indian mackerel (Rastrelliger kanagurta) as small pelagis fisheries resources and Ornate treadefin bream (Nemipterus spp.) as demersal fisheries resources. The problem in coastal North of Java and Blanakan is the increasing exploitation of fisheries resources that have caused biological and economical overfishing. The aimed of this research were to analysed exploitated rate of fisheries resources especially on Indian mackerel and Ornate treadefin bream, to make ecology-economy model for fisheries mangement, and to design alternative policy for fisheries management in North coastal Blanakan, Subang. Primary data were obtained by collecting the example of Indian mackerel and Ornate treadfin bream at TPI Blanakan, Subang. Secondary data were obtained by collecting the fisheries production data at KUD Mina Fajar Sidik, Blanakan, Subang. The results of primary data showed that the rate of exploitation (E) on Indian mackerel and Ornate treadefin bream each have reached 60,67% and 66,24%, it mean that both of the fisheries resources have been over explotaited. While secondary data revealed that for Indian mackerel the actual effort used has already exceeds the optimum condition of MSY and MEY, therefor the economic benefit also smaller than in the optimum condition of MSY, MEY. For the Ornate treadfin bream revealed that actual effort used also already exceeds the optimum condition of MSY and MEY, so that the economic benefit also smaller than in optimum condition of MEY, MSY.

Judul: Analisis Bioekonomi Sumber Daya Ikan Kembung Lelaki (Rastrelliger kanagurta) yang Didaratkan di TPI Blanakan, Subang, Jawa Barat
Abstrak: Indian mackerel (Rastrelliger kanagurta) is one of the economically important fish landed in TPI Blanakan. The purpose of this research is to know surplus production model that best fits the characteristics of fisheries indian mackerel through the application of five models that Schaefer, Fox, Walter Hibron, Schnute, and Clarke Yoshimoto Pooley (CYP). Research was conducted from July to August 2013. Schaefer Model is the model most appropriate surplus production to basic management of fisheries for indian mackerel in TPI Blanakan, although the value of the coefficient of determination (R2) of only 36%. Based on the results of bioeconomic analysis that the actual condition of the ndian mackerel resource in Blanakan has experienced overfishing. Maximum catches sustainable and economically optimum level of effort is 49.808 kg/year and 493 trip/year. Management plan that can be done is to set up an attempt arrest and quota setting catches.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
