Judul: : Kelayakan Usaha Penggemukan Kambing Jawa Randu pada Kelompok Tani Simpay Tampomas Desa Cibeureum Wetan Kabupaten Sumedang
Abstrak: In run businesses, fattening goat Jawa Randu, farmer groups simpay tampomas not based on knowledge, the group just rely on the experience and intuition course. The study is to analyze the feasibility of business fattening goatie java randu in the farmers simpay tampomas. The analysis used is a method of analysis non financial sensitivity of financial analysis and analysis. The aspect of non financial analyze about aspects of the market and marketing- the technical aspects, the aspect of management, legal aspects and social aspect. Financial analysis counting analysis based on npv, eligibility criteria irr, net b / c and payback period. Analysis of sensitivity of counting the influence of occurring price change against the feasibility of undertaking of fattening this goat. Based on the result of reckoning analysis of eligibility criteria business through investment produce npv 118 439 681, as much as rp net / c to b 1.67 irr by 26% and 4 years payback a period of three months. Thus the business of fattening done by farmer groups simpay tampomas worthy to be executed financially. Analysis of switching value to a decrease in the selling price of goats are worth 5.67 % and price was going to a goat as much as 10.72%.

Judul: Analisis Kelayakan Usaha Pertanian Terpadu Kambing Peranakan Etawa-Padi Semi Organik (Studi Kasus: PT Wirayasa Mandiri, Desa Wanasari, Kecamatan Bangodua, Kabupaten Indramayu, Jawa Barat)
Abstrak: Goat is the cattle with second highest productivity in Indonesia. Based on its productivity, goat is divided into beef goat and diary goat. PT Wirayasa Mandiri is the one of company that is breeding and growing double purpose diary goat resulted by excellent species of Etawa Crossbreed goat with integrated agriculture. Instead to produce goat milk, PT Wirayasa Mandiri also utilize waste resulted from the cattle as organic fertilizer and pesticide for semi organic paddy plantation. The aims of this research are understanding the feasibility of business by financial and non financial aspect analysis in husbandary of diary goat and semy organic paddy plantation with three scenarios. Non financial aspect which are used in this research are market aspect, tecnical, law and management, socioeconomic and culture, and also environment aspect. Based on value of investment criteria, integrated farming (scenario III) with harvest system by machine get the highest value of investment criteria, which are NPV (Rp796 376 365), Net B/C 20 (3.06), IRR (47.96 percent), and Payback Period (3 years and 4 months). Based on switching value analysis, increasing of feed price on scenario III is most sensitive with maximum limit of increasing value that is 4.27 percent.

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.
