Judul: Analisis Kelayakan Pengembangan Usaha Peternakan Sapi Perah KUNAK (Studi Kasus Usaha Ternak Kavling 176, Desa Pamijahan)
Abstrak: Milk is one of farm commodities with high consumption level. But, the gap between production and consumption of milk requires us to import from the other country. Furthermore, business developments necessary in order to fulfill the needs of national milk consumption. ‘Kavling 176’ is one of the farm that increases milk production. There for it needs feasibility analysis to ‘kavling 176’. Feasibility analysis is used to determine (1) non financial aspect of the business; (2) business development opportunities of the financial aspect; (3) sensitivity analysis of business. The method used in the financial aspect are Net Present Value (NPV), Internal Rate of Return (IRR), Net B/C Ratio, Payback Period (PBP) and Break Event Point (BEP). Based on the objective, obtained the following result as : (1) business are feasible according to the non financial aspect; (2) business development can be carried out with value NPV Rp 292.514.822,00, IRR 25,93%, Net B/C Ratio 1,42, PBP 2.83 years, and BEP Rp 225.155.564,00; (3) business are sensitive in decrease production of 22% and conditions combined 63%.

Judul: Analisis Kelayakan Usaha Peternakan Sapi Perah di Kawasan Usaha Peternakan (Kunak), Kabutpaten Bogor
Abstrak: Peternakan sapi perah di Kawasan usaha peternakan (Kunak) yang dibangun oleh KPS Bogor dihadapkan pada berbagai macam kendala seperti rendahnya harga jual susu yang ditetapkan Industri Pengolahan Susu (IPS) dan produksi yang fluktuatif. Hal tersebut dapat berpengaruh terhadap pendapatan peternak dan kelangsungan usaha di Kunak. Metode kualitatif digunakan untuk menganalisis aspek non finansial dan metode kuantitatif digunakan untuk menganalisis kriteria investasi. Seluruh aspek non finansial menunjukkan bahwa investasi peternak sapi perah Kunak di setiap pilihan layak dijalanakan. Analisis finansial pada peternak yang memiliki enam ekor sapi dan satu unit kandang menghasilkan NPV sebesar Rp 72.1 juta, Net B/C sebesar 1.53, IRR sebesar 24 persen dan PP selama 6.28 tahun.Analisis finansial pada peternak yang memiliki 12 ekor sapi dan satu unit kandang menghasilkan NPV sebesar Rp 217.4 juta, Net B/C sebesar 2.00, IRR sebesar 34 persen dan PP selama 4.66 tahun. Analisis finansial peternak yang memiliki 16 ekor sapi dan dua unit kandang menghasilkan NPV sebesar Rp 60.2 juta, Net B/C sebesar 1,17, IRR sebesar 15 persen dan PP selama 9.63 tahun.Hasil analisis finalsial pada semua pilihan usaha ternak layak dijalankan. Hasil analisis switching value pada semua pilihan usaha ternak sensitif terhadap perubahan produksi susu sapi atau harga susu per liter.

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.
