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.

Judul: Analisis Risiko Produksi pada Peternakan Ayam Broiler di Kampung Kandang, Desa Tegal, Kecamatan Kemang, Kabupaten Bogor, Jawa Barat.
Abstrak: Poultry is an important sub sector in contributing to GDP. One of poultry commodities which has big potential is broiler farm. Bogor District is one of broiler production central in West Java with growth rate about 7.75%. Meanwhile, broiler production in Bogor District is fluctuation. The purpose of this research is to analyze the risk of production sources, analyze the probability of risk source, and analyze the impact of risk sources in Kampung Kandang. Risk analysis broiler production was examined using primary data and secondary data. Primary data obtained through observation, interviews, discussions, and questionnaires with the farmers, while the secondary data obtained from the relevant literature. Method of data analysis on this research use descriptive analysis of the data using qualitative and quantitative risk analysis using the data. The sources of risk found broiler production is a weather, disease, and predators. Disease are a source of risk that may occur and the greatest impact, amounting to 91.62 percent and Rp 7 857 249. The results of mapping risk indicate that there are two kinds of management strategies such as preventive and mitigation strategies. In conducting a proposed strategy, the farmers should do strategy by prioritizing strategy that is caused by a source of risk of disease

Judul: Sintesis Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) dengan Variasi Konsentrasi Sulfur pada Substrat Kaca ITO
Abstrak: Film tipis Cu2ZnSnS4 (CZTS) merupakan bahan alternatif semikonduktor sebagai lapisan penyerap cahaya pada sel surya. CZTS dapat menggantikan senyawa silikon yang biasa digunakan sebagai bahan penyusun semikonduktor komersial. Kelebihan CZTS sebagai lapisan penyerap cahaya ialah ketersediaan bahan yang berlimpah di alam dan nilai koefisien absorpsi yang tinggi. Film tipis CZTS dibuat dengan variasi konsentrasi larutan sulfur menggunakan metode sol- gel dan spin coating sederhana pada substrat kaca inidium timah oksida (ITO). Setelah itu, film dikeraskan pada suhu 550 °C, selama 60 menit dengan dialiri gas N2. Difraktogram sinar X menunjukkan bahwa film tipis CZTS yang terbentuk dari kedua sampel memiliki struktur kristal kasterit dengan persentase yang kecil dibandingkan literatur. Sampel dengan konsentrasi sulfur 6M memiliki jumlah persen kristal yang lebih tinggi, yaitu 13,257% dengan ketebalan film 3,726–4,732 µm, sedangkan sampel dengan konsentrasi 3M memiliki persentase 7,538%. Sampel film tipis CZTS dengan konsentrasi sulfur 6M memiliki energi celah pita sebesar 1,876 eV dan nilai koefisien absorpsi sebesar 29,49 × 104 cm-1 menunjukkan hasil terbaik dan sesuai dengan kriteria film tipis CZTS komersil.
