Judul: Analisis Faktor-Faktor yang Mempengaruhi Risiko Produksi Ternak Kelinci (Studi Kasus Kelinci Hias di Desa Gunung Mulya, Kabupaten Bogor)
Abstrak: Rabbits have a great potential to be developed because these animals have the ability to growth and have very rapid development. Rabbits have a high biological potency, the high reproducibility, fast breeding, short birth intervals, high prolification, and easy to maintenance and do not require large tracts of land. The purpose of this study is to analyze and identify the factors of production that could affect production and livestock production risks of rabbits and analyze the factors of production used in influencing the risk of rabbits reproduction. To analyze these factors using a GARCH (1,1) because it can accommodate as well as estimate the production function of the average (mean production function) and variance (variance production function). The results showed that the average production function which are significant variables, ie variables broodstock, forage feed, feed concentrates, feed, and medicine as they are on the level of less than one percent. While in the variance function, the significant variables are variables breeders, feed concentrates, and labor. The influence of these variables in the production function of the average, ie variable broodstock, forage feed and concentrate feed, the more we use it will increase production, while for drugs variable the effect is vice versa. Influence of these variables in the variance function, ie three variables showed a negative parameter sign that more and more use of these three variables will reduce production risk.

Judul: Analisis Faktor-Faktor yang Mempengaruhi Risiko Produksi Kelinci di Kecamatan Ciawi Kabupaten Bogor.
Abstrak: Kecamatan Ciawi adalah salah satu penghasil kelinci terbesar di Kabupaten Bogor, namun produktivitas kelinci di Kecamatan Ciawi berfluktuasi, menandakan terjadinya risiko produksi. Tujuan dari penelitian ini adalah untuk menganalisis pengaruh faktor-faktor produksi terhadap risiko produksi kelinci yang dihadapi oleh peternak di Kecamatan Ciawi. Jumlah sampel yang digunakan dalam penelitian ini ada 33 responden. Metode yang digunakan dalam penentuan sampel adalah purposive sampling. Penelitian ini menggunakan model Just dan Pope sebagai metode analisis data. Hasil penelitian ini menunjukkan bahwa peningkatan jumlah indukan betina dan jantan meningkatkan produksi kelinci secara nyata, peningkatan penggunaan obat dapat meningkatkan risiko produksi kelinci secara nyata (risk inducing factor) dan peningkatan penggunaan suplemen dapat mengurangi risiko produksi kelinci secara nyata (risk reducing factor).

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.
