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: 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: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
