Judul: Studi Kelayakan Usaha Produksi Mesin Surimi (Kasus PT. Samudera Teknik Mandiri)
Abstrak: Surimi is minced meat of fish resulted from the separation process of bone, skin, and the scales of fish. Surimi can be processed into many kind of derivative products such as meatballs, sausages, nuggets, dragon legs, and fish crackers. Preparation of surimi can be done using fish bone separator which can save time and effort compared to traditional method. In Indonesia, the machine was first produced by PT. Samudera Teknik Mandiri, named SuritechTM. Since its establishment in 2007 the company has not been able to grow rapidly due to various constraints. The purpose of this research is to assess the feasibility of developing the business of SuritechTM machine. The method used in the research was descriptive and analytical feasibility study. The results showed the SuritechTM has potential market in Indonesia. The capacity production is 96 units machine per year and needs 12 workers. The investment required is Rp 1,871,111,000 consisting of fixed asset investment of Rp 1,089,935,000 and working capital of Rp 781,176,000. The NPV is Rp 1,119,328,337 and the IRR value is 30.38 percent. The net B/C is at 1.88. The payback period for the company is 3.76 years. The break even point (BEP) is Rp 679,484,088 or at the level of production of 31 units per year. The financial analysis showed that the development of machinery industry SuritechTM is feasible.

Judul: Rancangan Pendirian dan Analisis Kelayakan Usaha Produksi Alat Pemerahan Susu Sapi SOTE (Semi Otomatis Tipe Engkol)
Abstrak: Cow milk is the product of dairy cows that is needed by the people of Indonesia in order to meet their nutritional needs. Currently the world's milk production has reached about 385 000 million m3/year, while the national dairy industry of Indonesia in 1999 produced only ± 20% of total milk processing industry needs, so the rest still rely heavily on imported raw materials. Based on this condition it is important to increase the amount of cow milk production, by improving the efficiency and effectiveness of milk dairy using automatic milking machine. Due to the high price of milking machine, which is more than Rp 27 million, cow breeders do not want to buy. Therefore we need semi automatic milking machine. To solve these problems a semi automatic milking machine has been designed. The tool is called a dairy cow milking machine SOTE (Semi Automatic Type Crank). Because cow milking machine SOTE has never been produced specially workshop that produce this milking machine is required. The purpose of this research is to design a business of milking machine production SOTE and to analyze its feasibility level based on market aspects, technical aspects, institutional aspects / management and financial aspects. The size (area) of the workshop is determined by the needs of area for production and material flow from raw material to finished products. The layout of the room, equipment and machinery are arranged in such a way as to form the flow of production so that all rooms can be used efficiently. Analysis shows the workshop is financially feasible, indicated by three investment feasibility criteria: NPV, IRR, and the Net B/C. At the level of 10 % profit selling price (Rp Rp 7 159 348 per unit), the NPV value is Rp 371 883 233, net B/C 12.1 while the IRR value is 286.977 %. The sensitivity analysis shows that this business still feasible on labor cost increases of 5 %, raw material cost increases of 5 %, and both costs increase of 5 %.

Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
