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 Peternakan Ayam Broiler Di Kecamatan Ciampea, Kabupaten Bogor
Abstrak: Ciampea is one of the main areas centre broiler production in Bogor Regency. Fluctuation product in Ciampea indicates production risk. The risk analysis of broiler chicken production is investigated by using primary and secondary data. Data analysis method used is descriptive analysis by using qualitative data and quantitative. Then risk analysis by using quantitative data. Based on the observation in the research site, risk sources of broiler chicken are disease, climate, pest, and quality of DOC. Disease outbreaks is the risk sourcethat probably happens and the biggest effect that is 46% and at least Rp15 628 053. The risk mapping result shows that disease, climate and DOC can be solved with preventive strategy.

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.
