Judul: Pengaruh Kemitraan Terhadap Risiko Produksi Usahaternak Ayam Broiler di Kecamatan Pamijahan Kabupaten Bogor
Abstrak: Kecamatan Pamijahan merupakan sentra produksi daging ayam broiler, namun peternak menghadapi risiko produksi dan melakukan upaya untuk meminimalkan dengan kemitraan. Tujuan penelitian ini adalah untuk menganalisis pengaruh faktor-faktor produksi terhadap risiko produksi ayam broiler, menganalisis tingkat risiko, dan menganalisis pengaruh kemitraan terhadap risiko produksi usahaternak ayam broiler di Kecamatan Pamijahan Kabupaten Bogor. Pengambilan responden untuk penelitian ini menggunakan metode simple random sampling untuk peternak mitra dan metode sensus untuk peternak non mitra dengan jumlah masing-masing peternak adalah 30 responden. Penelitian ini menggunakan analisis model Just and Pope untuk mengetahui pengaruh faktor produksi terhadap risiko produksi dan analisis tingkat risiko untuk mengetahui besar risiko yang dihadapi peternak. Hasil penelitian ini menunjukkan bahwa variabel yang berpengaruh nyata terhadap produktivitas ayam broiler adalah pakan, obat-obatan, vitamin, dan dummy kemitraan, sedangkan dalam fungsi variance produktivitas, variabel yang berpengaruh nyata adalah vitamin dan sekam. Analisis tingkat risiko menunjukkan bahwa risiko yang dihadapi peternak mitra lebih kecil dibandingkan peternak non mitra. Kemitraan memiliki pengaruh yang tidak signifikan menurunkan risiko produksi peternak ayam broiler.

Judul: Risiko Produksi Ayam Ras Pedaging Pada Peternakan di Kecamatan Pamijahan Kabupaten Bogor, Jawa Barat
Abstrak: Husbandry is one of the agricultural sector which has a potential to be developed. One of the many husbandry commodities grown in Indonesia, especially in West Java is broiler. Similarly with other agribusiness, broiler husbandry also has risk especially production risk which seen from the chicken mortality at each production period. This research objectives are to indentify production risk sources, to analyze the sources’s probability and impacts, and to determine alternative strategy due to reduce the risk probability and impacts. To reach the research objectives, this research use several method such as Z-score and Value at Risk (VaR). Production risk sources at broiler husbandry in Kecamatan Pamijahan are weather, pests and predators, disease, and environmental disorders. According to probability the source which has the biggest probability is pests and predators and the lowest probability is environmental disorders. The biggest impact caused by disease and the lowest impact caused by environmental disorders.

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.
