Abstrak: This raearch focuses on management qrtdization of hsgm motor fishes in efloorts of improving the prosperity of &hermen in Serang Regency. The objective of this research is to determine optirnalization measures in the management of bagan motor fisheries and to d n e the prospaity level of hap motor fishermen and their families. Data gathered include biological and economical aspects of bagan motor fisheries, which is prmsed using Gordon-Schaefer Statistical Model. The prosperity level is detemuned using the 11 indicators of households prosperity level set by the Ndond Statistical Burem, derived &om SUSENAS 1491. The result shows b d on the 4 capture, the mmagement of anchnvy fisheries using bagm motor in Semg Regency is still below the Maximum Sustainable Yield (MSY), Maximum Ecmmic Yield {MEY) and o wa ccess (a)F.u rhemum, it still has the opporhmily to increase the number of fishing fleet (boai units), ked on the fact that the current number of operating bagan motor in the region is 14 units with fishing effort of 3,020 trips per year. Regarding the prospity level set by BPS, it h w s that most of the fshermen's households in S m g Regency are considered highly prosperous. lt is expected that the economical and biological overfishing will not threaten the sustainability of anchovies fishmies resour= and deteriorate the prosperity of the bagan motor fishermen, in order to keep the bagan motor fisheries management in Serang Regency sustained. Stringmi and consistent control over fishing efforts, total production d the number of fleet should be considered to reach these objectives.

Judul: Pengembangan Perikanan Tangkap Berbasis Optimasi Sumberdaya Ikan Pelagis di Kabupaten Banyuasin Propinsi Sumatera Selatan
Abstrak: The pelagic fish is one of potential fishery resources in Banyuasin District. The production of pelagic fish fishery landed in Banyuasin District was 29,6 ton in year 2006. The objectives of the research were 1) to determine fishing technology for pelagic fish which more effective, efficient and sustainable based on biological, technical, social, economic and environment aspect; 2) to allocate optimum of pelagic fish catching unit in Banyuasin District; and 3) to determine development strategy of pelagic fisheries. The result of this research indicated that drift longline fishing technology is more effective, efficient and sustainable than drift gillnet and liftnet. The number of optimum allocation of fishing unit has been calculated which consist of drift longline 51 unit, drift gillnet 45 unit and liftnet with 55 unit. The output of feasibility analysis of drift longline fishery is the study area, indicated profit of Rp. 18,767,666, its NPV value was Rp. 55,855,075, Net B/C was 2.22, the BEP value was Rp. 39,055,258 that equal to production 23,669 kg, the ROI and IRR value were 41 % and 48. The output of feasibility analysis of drift gillnet fishery is the study area, indicated profit of Rp. 17,320,000, its NPV value was Rp. 46,437,216, Net B/C was 2.08, the BEP value was Rp. 26,951,872 that equal to production 16,171 kg, the ROI and IRR value were 40 % and 48 %. The output of feasibility analysis of liftnet fishery is the study area, indicated profit of Rp. 23,610,000, its NPV value was Rp. 214,477,312, Net B/C was 3.94, the BEP value was Rp. 31,292,924 that equal to production 16,506 kg, the ROI and IRR value were 32 % and 83 %. The development strategy of pelagic fisheries in Banyuasin District are: (1) optimization pelagic fish fishery with drift longline; (2) development pelagic fish fishery focusing in 6-12 mile zone; (3) Increase management effort of fisheries business; (4) revitalization of fisheries infrastructure and facility; and (5) Empowering scale of fishing fleet and its technology.

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.
