Judul: Analisis Risiko Produksi Usaha Peternakan Ayam Kampung di PT Sumber Unggas Kabupaten Bogor
Abstrak: Konsumsi per kapita ayam kampung meningkat setiap tahun, peningkatan itu mengindikasikan peluang usaha ayam kampung memiliki prospek yang baik. Hal itu dimanfaatkan oleh PT Sumber Unggas yaitu dengan menjalankan usaha peternakan ayam kampung. Tetapi, tingkat mortalitas ayam selalu melebihi standar yang ditetapkan perusahaan dan berfluktusai selama 18 siklus poduksi, hal itu disebabkan keberadaan risiko produksi. Penelitian ini bertujuan untuk mengetahui sumber risiko produksi ayam kampung yang sesuai dengan kondisi peternakan. Kemudian menganalisis probabilitas dan dampak risiko serta merumuskan alternatif strategi. Penelitian ini menggunakan metode z-score dan Value at Risk dalam menganalisa probabilitas dan dampak risiko. Hasil dari penelitian adalah teridentifikasinya empat sumber risiko yaitu penyakit, suhu, kualitas Day Old Chicken (DOC), dan afkir. Nilai probabilitas yang diperoleh adalah penyakit 39.74 persen, afkir 33 persen, suhu 32.28 persen, dan kualitas DOC 25.14 persen. Sedangkan nilai dampak risiko yang diperoleh adalah penyakit Rp130 933 510, afkir Rp47 579 427, suhu Rp31 266 623, dan kualitas DOC Rp33 476 182. Penelitian ini merumuskan dua strategi yaitu strategi preventif dan strategi mitigasi dalam menangani sumber risiko yang teridentifikasi.

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: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
