Judul: Business  development  feasibility  of    chicken  breeding  in  warso  unggul gemilang in Bogor
Abstrak: Permintaan pasar ayam kampung yang tinggi memberikan peluang terhadap pengembangan bisnis pembibitannya. Pengembangan usaha dilakukan untuk meningkatkan produktivitas ayam kampung melalui penggunaan teknologi modern, sehingga penelitian ini dilakukan untuk menganalisis kelayakan pengembangan usaha dengan penerapan mekanisasi produksi dan mengukur kepekaan bisnis pada skala 20 000 ekor indukan. Metode analisis yang digunakan adalah metode analisis nonfinansial dan finansial. Analisis nonfinasial dilakukan berdasarkan penilaian terhadap aspek pasar, aspek teknis, aspek manajemen, aspek hukum, aspek sosial dan lingkungan. Analisis finansial dilakukan berdasarkan kriteria penilaian investasi berupa Net Present Value (NPV), Internal Rate of Return (IRR), Net Benefit per Cost (Net B/C) dan Payback Period (PP). Analisis kepekaan bisnis digunakan untuk mengukur batas perubahan peningkatan harga pakan dan penurunan harga DOC. Hasil analisis menunjukkan bahwa usaha pembibitan ayam kampung dengan pengembangan memberikan manfaat lebih besar daripada tanpa pengembangan. Pengembangan bisnis sebaiknya diterapkan oleh Warso Unggul Gemilang, Market demand is high provide opportunities for business development breeding free-range chicken. Business development is done to increase productivity of free-range chicken through the use of modern technology, sothis research was conducted to analyze business development feasibility with application of production mechanization and measuring business sensitivity on a scale 20 000 parent tail. Analysis method has been used is nonfinancial analysis and financial analysis. The analysis was done based on nonfinancial analysis such as market aspects, technical aspects, management aspects, legal aspects, social and environment aspects. Financial analysis is based on the assessment criteria of investment such as Net Present Value (NPV), Internal Rate of Return (IRR), Net Benefit per Cost (Net B/C), and Payback Period (PP). Analysis of sensibility business used to measure the changes increased the price of feed and DOC prices decreased. Results of analysis showed that business of free-range chicken breeding with development of greater benefit than without development. Business development should be applied by Warso Unggul Gemilang.

Judul: Analisis Kelayakan Pengembangan Usaha Peternakan Ayam Broiler Di Desa Cihideung Udik, Kabupaten Bogor
Abstrak: Broiler chicken husbandry is the most favorited kind of husbandry because it has high level of demand of its product. Bogor is one of regions in West Java that has high demand of chicken husbandry product. The study aims to ( 1 ) analyze feasibility enterprise development of chicken farmer broiler look from non financial aspects as aspects market, the technical aspects, aspect management and legal, aspect social and cultural and environmental aspects ( 2 ) analyze feasibility enterprise development of chicken farmer broiler look from financial aspects ( 3 ) analyzed levels of sensibility (switching value) feasibility enterprise development of chicken farmer broiler. Based on the analysis aspect financial and non financial, business of chicken broiler has worthy to be developed. Because it seen from Net Present Value (NPV) was IDR6 058 082 368, net B/C 2.84%, IRR 39.26%, and Payback Period 3.2 years. The Discount Rate was 6%. Switching Value analysis showed that the increasing price of feed price by 10.11% and decreasing price of selling chicken by 6.31% were still feasible. Chicken broiler farm more sensitive to decrease price of selling chicken than increasing price of feed.

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.
