Abstrak: The objectives of this research are: (1) to describe the characteristic of farmer and their sheep farm; and (2) to analyze the financial feasibility of sheep farm and it's sensitivity. Cluster random sampling applied to choose 164 sample from 700 sheep farmers household population in Cibunian Village. The sheep farm were clasified into three categories based on ownership of sheep, namely scale I (0,75- 2,50 SDD or Adult Sheep Unit); scale II (2.51-4.75 SDD); and scale III (4,76-8,50 SDD). The result of this research showed chat generall (52,44%) farmer in Cibunian village comitted their sheep farm on scale I. Farmer of each scale in avarage were categorized into productive aged, have lots of experience on shap farm activities, but they have low education. The result of financial feasibility analysis showed that for 10 years at the interest rate of 9,50%, Net Resent Value (NPV)of sheep farm on scales I, II and III respectively is Rp (3.537.029,00); Rp (1.413.826,00); and Rp 1.770.5 19,00, with the values of Benefit Cost Ratio (BCR) are 0.67; 0,89; and 1 ,I 0. Internal Rate of R e m (IRR) on scale I1 and 111 respectively is 057 and 16,56%. Sensitivity analysis was counted on scale Ill. Sheep farm on scale 1II was not feasible if farm costs increased more than 9,97% or farm revenues decreased more than 9.06% ceteris paribus.

Abstrak: Sheep is the third biggest contributors of ruminant families for meat national product. MT Farm is one of a farm-based agribusiness companies that planning to expand its business to fulfill market requirements. The aim for this study to analyzing the feasibilty of sheep business expansion at MT Farm based on financial and non financial aspects. This study also analyzing sensitiveness levels of business expansion by Switching Value Analysis. Result of this study shows that business expansion by analyzing non financial aspects is feasible to run. Result of financial analysis is also feasible to run based on investment criteria, that NPV Rp 566,181,930, Net BC is 2.01, and IRR is 22.55 percent of Payback Period means investment costs will return in two years four months and one day. While Switching Value Analysis shows the ascend limit of sheep’s mortality is 2.107109305 percent, so ascending in prices of lamb is 3.1854194939394 percent. Switching Value Analysis shows that ascending of sheep’s price give more influences than ascending of sheep’s mortality.

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.
