Judul: Optimalisasi Pengelolaan Perilman Bagan Motor dalarn Meningkatkan Kesejahteraan Nelayan di Kabupaten Serang Prorinsi Banten
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: Model of management of capture fisheries area in Banten Bay
Abstrak: Banten Bay is area which quite rapid development for many activities. Industrial waste disposal, domestic, over fishing, coral exploitation, reclamation, vessel traffic, and environmental damage, cause interest multi sector conflict in managing sea area. General objective of the research is to create model of management of sustainable capture fisheries area in Banten Bay. The specific objectives are to (1) determine utilization status and development prospect of capture fisheries; (2) determine leading commodity; (3) determine environmentally friendly fishing gears, (4) establish utilization zone; (5) arrange policy strategy in managing capture fisheries; and (6) simulate of model of management of capture fisheries. Evaluating utilization status and development prospect of capture fisheries was conducted using surplus production method with bionomic model. Determination of leading commodity was conducted with LQ value, IS, and descriptive method. Environmental and sustainable fishing gear was analyzed using CCRF criteria with scoring method approach. Zoning of capture fisheries area utilization was conducted by GIS. Management strategy of capture fisheries area was conducted with SWOT and AHP. Simulate of model of management of capture fisheries was conducted with LGP and model simulation of sustainable fish resources and salary fisherman. The result showed that utilization status and development prospect of capture fisheries in Banten Bay can still be developed for 9 species from 23 species. Squid, anchovy, and crab were commodities with high comparative advantages. Hand line, boat lift net, and gillnet were environmentally fishing gears. Zoning of Banten Bay utilization are consist of aquaculture, recreation, conservation, capture fisheries, fishing port, and industrial zone. Zone of capture fisheries was composed base on fishing ground eligibility indicator, suitability of fishing gear with fishing ground, minimum of conflict potency, availability of infrastructure, and environmental carrying capacity. Capture fisheries zone is divided into three zones, that are (i) passive zone, (ii) passive and outboard fishing boat zone, (iii) active and inboard fishing boat zone. Based on LGP analysis, maximum catch was 1.747,259 ton/year, alocation for fishing gear of gillnet, danish seine net, set lift net, boat lift net, boat seine, hand line, guiding barrier trap, and monofilament gillnet were 3, 11, 11, 6, 2, 5, 0 and 0 unit, respectively. The proposed strategy in managing Banten Bay area were (1) utilization strategic location of Banten Bay with optimalization leading commodity for providing fish demand; (2) taking advantage of high availability of human resources and fisherman concern to manage capture fisheries area; (3) utilization local government support and regional autonomy to make policy in structuring and expansion of fishing area and involving coastal communities in the management. Model of management of capture fisheries area in Banten Bay can be increase of salary fisherman as much as 25% from first scenario and take care of sustainable fish resources the periode of time 18 years.

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.
