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 CV Mitra Tani Farm di Desa Tegal Waru Kecamatan Ciampea Kabupaten Bogor
Abstrak: CV Mitra Tani Farm is a sheep and goats fattening bussiness located in Tegal Waru Village Ciampea Subdistrict Bogor Regency. In working out the sheep fattening, MT Farm can afford ownership or partnership with farmers who currently partnering with the business units MT Farm "Rumah Kambing". The purpose of this study are: 1) to analyze the feasibility of fattening sheep CV Mitra Tani Farm viewed from the non-financial aspects such as market aspects, technical aspects, management aspects, legal aspects, social and environmental aspects, 2) to analyze the feasibility of fattening sheep CV Mitra Tani Farm if cultivated by ownership or patnership views on the financial aspects of the NPV, IRR, Net B/C, and Payback Period, and 3) to analyze the switching value of this sheep fattening CV Mitra Tani Farm if there is a decrease in variable cost of production and increase the feasibility of the venture. The results of this study show 1,040 sheeps fattening business in CV Mitra Tani Farm is feasible based on non-financial aspects and financial aspects show this bussiness which is feasible by ownership or partnership because it has appropriated the investment criteria. Switching value calculation results show the maximum limit of increasing lamb price with ownership is 6,33% and the maximum decrease in carcass percentage is 5,82%. Therefore, the maximum of increasing lamb price with partnership is 2,91% and the maximum decrease in carcass percentage is 2,67%.

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.
