Judul: Analisis kelayakan finansial modernisasi usaha ternak sapi potong di Kecamatan Wanayasa, Kabupaten Banjarnegara
Abstrak: Wanayasa is one of the highest populations of beef cattle districts in Banjarnegara regency, but mostly of the beef cattle feedloting are efforted by small scale and simple technology. This research studies about feedlot technology changing from traditional technology to the modern one. The purpose of this researches are to analyze modernization of feedlot financial feasibility. Respondents of this research are cattleman of Wanayasa which are containts seventeen respondents as the representation of traditional feedlot and CV Brahman Putra as the representation of modern feedlot. This research uses investation criteria analysis method. The results shows that modernization of feedlots are feasible to be done and the decreasing of the beef cattle selling price are the most determine factor feedlot feasibility

Abstrak: The objective of the research were 1) to identification internal and ekstemal factors which can influences beef cattle farming development in Surade Sub-District, 2) to formulate the strategy of beef cattle development in Surade Sub-District. Primary data obtained by direct interview with the beef cattle farmer, used questionaue as the tool. Secondary data obtained from relevant institutions sources that related with the topic of the research, the data analyzed descriptive quantitative method. The result of feseability study analysis showed Net Present Value (NPV) equal to Rp. 5,670,144,68, Benefit Cost Ratio (BCR) equal to 1.52, Interest Rate Ratio (IRR) equal to 22% and Pay Back Period (PBP) equal to 4 year. The return cost ratio (RiC ratio) of beef cattle farm business analysis, showed that ratio as 1.70 value. It means that the beef cattle farm business were profitable with earning equal to Rp. 2,286,006,94. Base on data feseability study analyzed showed beef cattle development in Surade Sub-District were feseable. Result of analysis of SWOT in the form of strategy S-0 that is cooperation with financial institution to increase working capital, cooperation with government institution to introduce artificial insemination technology. Strategy of W-0 that is re-activated farmer group in marketing beef cattle product, more recruit farmer adviser to increase farmer knowledge in beef cattle farming. Strategy S-T that is to increase farmer knowledge in animal health, to increase animal productivity by applicated advance breeding technology. Strategy W-T that is to increase farmer personal skill in beef cattle farming, it can be implemented by coopemtion between farmer group and government intsitution.

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.
