Judul: Analisis Risiko Usaha Peternakan Ayam Broiler Dengan Pola Kemitraan Dan Mandiri Di Kota Sawahlunto/Kab. Sijunjung
Abstrak: One commodity that many farms are cultivated by breeders of broiler chickens. Broiler breeding process has a shorter culture period than other farm commodities. Broiler chicken farming is inseparable from the existence of business risks. The most common risk is the risk of production and price risk. On-farm production of plasma risk is one risk is quite high, while the independent farm price risk is the risk that a major effect on earnings. This study aims to analyze the sources of risk that affecting farmer’s income, the effect of production risk and price risk to the farmer’s, analyzing the influence of a partnership, as well analyzing alternative strategies appropriate to address existing risks. The method used is a risk analysis, revenue analysis and analysis of the revenue balance (R/C Ratio). The comparison of income between farmers and the plasma independent of Rp 58 618 500 and the value of R/C Ratio of the received independent farmers is 1.16. while in this period plasma farmers suffered losses of Rp -4 465 900 and R/C Ratio of 0.73

Judul: Production Risk Analysis on Broiler Farm (Case study broiler farm owned Mr. Kamal in Silebu Village, Pancalang Sub District, Kuningan District, West Java) S
Abstrak: Peternakan ayam broiler milik Bapak Kamal menjalankan usaha peternakan melalui hubungan kerjasama kemitraan inti-plasma dengan PT Aretha Nusantara Farm. Meskipun telah menjalin kemitraan inti-plasma, peternakan milik Bapak Kamal tetap menghadapi risiko produksi. Tujuan penelitian ini adalah menganalisis sumber-sumber risiko produksi, menganalisis probabilitas sumber-sumber risiko dengan metode z-score, menganalisis dampak sumbersumber risiko dengan metode value at risk, dan menganalisis alternatif strategi sumber-sumber risiko produksi di peternakan milik Bapak Kamal. Metode analisis yang digunakan adalah analisis deskriptif dan analisis risiko yang terkait dengan tujuan penelitian ini. Sumber risiko yang ditemukan pada produksi ayam broiler adalah kualitas DOC (Day Old Chick) yang buruk, kondisi cuaca, serangan penyakit, dan hama predator. Hasil pemetaan risiko menunjukkan bahwa ada dua jenis strategi manajemen risiko yaitu strategi preventif dan strategi mitigasi. Sumber risiko yang sebaiknya diutamakan dalam melakukan majemen risiko adalah kualitas DOC yang buruk karena merupakan sumber risiko yang memiliki kemungkinan dan dampak paling besar.

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.
