Judul: Analisis Kelayakan Usaha Konveksi Kulit Domba di Perusahaan Perorangan Kulit Kalong, Bogor
Abstrak: There is a number of UMKM in Indonesia which increase 1.44 percent a year. This is the main attraction to open a business convection sheep leather view of each year business of Sheep Leather Convection has increased turnover by an average of 10 percent. This study aims to analyze a feasibility study the business of Sheep Leather Convection. Data analysis method uses both qualitative and quantitative that contains non financial aspects and financial aspects. The qualitative consists of market aspects, technical aspects, management & legal aspects, and social, economic, and environmental aspects. In order to provide better feasibility on financial aspects, the quantitative consists several criteria which are NPV, Net B/C, IRR, and Payback Period and the switching value. The results of this study demonstrates that Sheep Leather Convection has a sufficient feasibility for financial aspects and non financial aspects.

Judul: Analisis Kelayakan Usaha Penggemukan Domba Pada Mitra Tani Farm, Kecamatan Ciampea, Kabupaten Bogor
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: Pengaruh Pairing pada Isotop Sn dengan Menggunakan Pemodelan Sembilan Tingkat Energi
Abstrak: Formation of the neutron-rich tin isotopes (Sn isotopes) is the one of the interesting topics in the field of nuclear reaction, especially regarding the stability of the heavy nuclei. Calculations of total energy using the BCS approach using five energy levels can only calculate the total energy up to Sn50132. On the other hand, the experiment continues and has exceeded the formation of isotopes. Therefore, there is need for a new model to accomadate more neutrons. In this research, Sn isotopes is modelled using nine energy levels and constant interaction potential to explain the pairing phenomenon up to Sn50154. However, to obtain more accurate results, other methods to minimize the differences with the experimental results are clearly needed here.
