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: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
