Abstrak: The objectives this research were : (1) to assess the impact of fishing unit assistance to increasing fisheries income level, in North Halmahera Regency, (2) to assess influence mayor factors of fisheries income level (3) to selection of alternative policy strategy for sustainable increasing fisheries income level. Result of this research show that, most of the level of fishing technology used is relatively simple, except pajeko fishing technology has relatively advanced technology. The fishing unit’s empowerment program significantly positive impact on improving the income of fishermen. Based on feasible and investment criteria analysis indicate pajeko fishing unit of gillnet, bottom long line and mini purse seine more feasible to be developed in North Halmahera regency. Result of matrix internal factors analysis summary (IFAS) indicated that total factor internal value in IFAS between 3,1 ³ 2,5, its mean internal condition had strength to overcome weakness state. Whereas result external factors analysis summary (EFAS) show that the total EFAS value between 2,6 ³ 2,5, its mean system capable to response external state. Base on SWOT (strenght–weakness, opportunity-threat) analysis obtain six development strategies of increasing fisheries income: (1) Scale business fisheries development; (2) Improved fishing infrastructure; (3) Development of market aces (4) Training programs for fisheries capacity development; (5) The Law enforcements; (6) Partnership development.

Abstrak: North Halmahera Regency with its sea area of 19536.02 km2 (78%) has the potential of fish resources (standing stock) accounting for 664,382.48 tons with sustainable potential fish production (the Maximum Sustainable Yield / MSY) of 347,191 tons per year, i.e., 211,590 tons of pelagic fish and 135,005 tons of demersal per year. The problem in the development of capture fish in North Halmahera is that its excellent commodities are as yet unknown and the policies in the fishery production are not based on excellent commodities. This research is to examine the superior commodities of fishery production, and the policies in capture fishing production in order to increase the income of fishermen. To determine the excellent commodities, the following analyses were made: (1) production continuity, average production, prices, processing and marketing, (2) Method of Location Quotient (LQ) and (3) SWOT Analysis. The results showed that of 38 species of fish that were analyzed, 31 species were of a continuous type and 7 species of non-continuous type. The average fish production is below the average production of all types of fish except for cakalang fish of 11,131.472 tons and flying fish of 4405.296 tons per year. The fish price is generally below average price of all types, except for the following types of fish: beronang, kerapu, lencam, kakap, and kurisi, the prices of which are higher than the average price. The fish products marketed in the local market / overseas are for example kerapu, cakalang and tuna. Fish products are always marketed in fresh form. Only julung-julung fish is marketed after it is processed by fumigation. Three kinds of fish are also exported they are kerapu, cakalang and tuna. The results of LQ calculation show that there are 12 species of fish with a value of LQ>1, namely: kuweh fish, kerapu, kerong-kerong, teri, tembang, julungjulung, tongkol, lemadang, cakalang, mackerel tuna and cucut. Based on the scoring analysis of commodities in terms of production continuity, production, pricing, processing, and marketing associated with the value of LQ, six kinds of fish as excellent commodities in North Halmahera Regency are cakalang, kerapu, anchovies, julung-julung, tuna, and tongkol. Flying fish, although its production is quite high and can be improved, has the value of LQ <1, so it can not be recommended as a superior fish species. Based on the results of the SWOT analysis, there are six government policies of North Halmahera regency related to the development of capture fisheries, increasing fishing fleet is a top priority followed by the development in the processing of captured fish. Both policies are closely related to labor absorption and economic improvement.

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.
