Judul: Analisis kelayakan usaha Anggrek pot Mita Permata Anggrek di Kelurahan Pasir Mulya Kota Bogor
Abstrak: Orchid pot is one of floriculture product that has the potential to be developed . The purpose of this study is to analyze the feasibility of orchid pots business Mitra Permata Anggrek, by analyzing the 3 varieties of varieties of Dendrobium, Vanda and Phalaenopsis. The analytical method used is the analysis is non-financial aspects such us the market, technical aspects, management and legal aspects, social aspects of economic, and environmental aspects. Financial analysis of investments is determined on several criteria such as NPV, IRR, Net B / C and Payback Period. Non-financial analysis is done with 4 scenarios, and the result is business orchid pots is proper to operation. Sensitivity analysis is performed to test the feasibility of the two conditions that the rising price of inputs (seeds) and reduction in the amount of production with calculate switching value. Results of test sensitivity for 4 scenarios show in conditions that the rising price of inputs (seeds), Orchid pot business use the 3 scenario its more sensitif. The results of test sensitivity reduction in the amount of production is Orchid pot business use the 3 scenario its more sensitif.

Judul: Analisis kelayakan usaha budidaya anggrek dalam menunjang tujuan program sentra anggrek Kota Tangerang Selatan
Abstrak: Pemerintah Kota Tangerang Selatan bekerjasama dengan Badan Pengkajian dan Penerapan Teknologi untuk menjadikan Kota Tangerang Selatan menjadi sentra anggrek. Pemerintah mencanangkan program sentra anggrek dengan salah satu tujuannya untuk menggerakkan perekonomian masyarakat. Tujuan dari skripsi ini adalah menganalisis kelayakan aspek non finansial, finansial, dan tingkat kepekaan usaha budidaya anggrek dalam menunjang tujuan program sentra anggrek Kota Tangerang Selatan. Untuk mencapai tujuan ini digunakan metode kelayakan aspek non finansial maupun finansial. Secara umum, budidaya anggrek dikatakan layak baik secara non finansial maupun finansial pada berbagai skala. Sedangkan, program sentra anggrek hanya layak dijalankan pada skala usaha besar karena memiliki NPV lebih dari present value UMK Kota Tangerang Selatan.

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.
