Judul: Analisis Pendapatan Usahatani Penggemukkan Domba di Mitra Tani Farm (Studi Kasus: Desa Tegal Waru, Kecamatan Ciampea, Kabupaten Bogor)
Abstrak: Lamb is one of the farm commodity consumption increased from year to year. Indonesia has not been able to fulfill the needs of domestic lamb. The continuing slowdown of production shows that the demand for lamb is on the rise. The increasing deman for lamb is a signal for farmers who seek lamb chops that will ultimately affect their revenue and income. This study aims to detemine the variabilty of lamb fattening in farmm cost structure, acceptance, revenus, and efficiency of lamb fattening in farming income. Location selection is done by purposive sampling in the village of Tegal Waru, Ciampe district, Bogor regency as one of the centres of lamb commodities in Indonesia. Analyses were perfomed with analysis of farming, supported by primary and secondary data. The results showed that fattening sheep farming in the Mitra Tani Farm efficient and profitable, visible from the R / C ratio of 1.54 over cash costs and R / C ratio of the total cost of 1.50

Judul: Analisis Kelayakan Usaha Penggemukan Domba Pada Mitra Tani Farm, Kecamatan Ciampea, Kabupaten Bogor
Abstrak: Sheep is the third biggest contributors of ruminant families for meat national product. MT Farm is one of a farm-based agribusiness companies that planning to expand its business to fulfill market requirements. The aim for this study to analyzing the feasibilty of sheep business expansion at MT Farm based on financial and non financial aspects. This study also analyzing sensitiveness levels of business expansion by Switching Value Analysis. Result of this study shows that business expansion by analyzing non financial aspects is feasible to run. Result of financial analysis is also feasible to run based on investment criteria, that NPV Rp 566,181,930, Net BC is 2.01, and IRR is 22.55 percent of Payback Period means investment costs will return in two years four months and one day. While Switching Value Analysis shows the ascend limit of sheep’s mortality is 2.107109305 percent, so ascending in prices of lamb is 3.1854194939394 percent. Switching Value Analysis shows that ascending of sheep’s price give more influences than ascending of sheep’s mortality.

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.
