Judul: Business Plan of Chocolate Bar Industry in Bogor
Abstrak: Cacao is an important agroindustrial product of Indonesia. Most of Indonesian cacao is exported in form of cacao beans. In contrast, the market of processed cacao such chocolate bars is filled by imported products. The purpose of this research is to make a business plan of chocolate bar company. The research scope includes studying market and marketing aspect, technological aspect, management and organizational aspect, and also financial aspect of a chocolate bar company in Bogor. The data collection methods used are interviews and documents and other secondary data collections. The data are mainly analized using investment analysis such as NPV, IRR, payback period, and risk analysis. The chocolate bar company is located in Cijeruk, Bogor, considering the access to available milk supply as an important raw material, while the location also has satisfactory infrastructure, human resource, and access to markets. The factory capacity is 1000 kg per day. The main raw materials are cocoa liquor and cocoa butter, supplied from a company from Tangerang. The company needs 33 workers. In terms of environment concerns, the company will only produces very small number of solid and liquid waste, which are safe for environment. The total investment needed is Rp. 6.737.746.660,- consisting of fixed asset investment Rp. 5.825.673.700,- and working capital Rp. 912.072.960,-. The NPV value is positive Rp. 5.387.822.787,-. The IRR is 22 percent. The Net B / C value is 1,80. The Payback period is 5,66 years. The investment figures show that the company is feasible to set up.

Judul: Analisis Kelayakan Bisnis Pengolahan Coklat dengan Contoh Kasus Alania Chocolava
Abstrak: Indonesia is the 3rd largest cocoa bean producer in the world, but of 440 thousand tons of cocoa beans in the country is only 30 thousand tons were processed into chocolate foods. Chocolava Alania is one of the companies that process the chocolate base (cocoa powder, cocoa liquor and cocoa butter) into a variety of foods from chocolate. . The purpose of this study was to analyze the feasibility of the business of cocoa processing industry in Indonesia to see how the level of the existing feasibility chocolate industry in the country with cocoa processing business case Chocolava Alania. The results of the study of the financial aspects, Alania Chocolava decent run, because the results show a positive NPV of Rp 1 274 140 425greater than zero, the net b / c worth 2 feasible because more than 1. IRR is 33 percent greater of the discount rate was set at 7 percent. payback period of 4 years and 3 months, analitical switching value showed maximum decrease of sales until 15,6 persen. Analysis of the nonfinancial aspects, which include legal aspects, management, technical, market feasible

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.
