Judul: A Study of Balita Fish Agribusiness Development (A Case Study at UD. Suhada, in Cianjur Regency).
Abstrak: The world market demand for fishery products is increasing even frequently not fulfilled. Therefore, it required an effort to overcome the problems in fulfilling the demand for fishery products. Efforts in the field of aquaculture freshwater fish and has the potential to provide a significant contribution to the lives of the people especially for the micro, small and medium enterprises. UD. (Enterprises Trade) Suhada are entrepreneurs in the agribusiness freshwater fisheries, particularly in the agribusiness of fish toddler. Balita fish is a type of freshwater fish; the term ‘balita’ is taken from the acronym of ‘dibawah lima-tiga’ (under five-three) centimeters or in short it means fish under 3-5 cm in size. Types of freshwater fish cultivated for balita fish at UD. Suhada is a type of tilapia and goldfish. The purpose of this study is to examine the feasibility of balita fish agribusiness investment in UD. Suhada; identify the internal and external factors that influence the development of agribusiness balita fish at UD. Suhada; formulate and recommend appropriate alternative development strategies to be applied to agribusiness balita fish at UD. Suhada in business development. Methods of data collection using purposive sampling method, is by deliberately selecting the sample to be studied as a respondent. Respondents were selected from the management and the workers UD. Suhada. Financial analysis at 14 percent of interest rate and 5 years of project lifetime resulted in feasible decision with Rp. 1, 105,005,110 of NPV; 4.85 of net B / C Ratio; 38.95 percent of IRR, 3 years and 5 month of PBP; and Rp. 1, 522,035,876 or 32.725 kg of BEP. The combination of value IFE EFE values for 2.688 and 2.651 in the IE matrix shows that the position of the business in V (five) cells, that cell growth. Based on the SWOT analysis and QSPM analysis the strategic priorities is to create a diverse variety of products while maintaining the quality of balita fish (score 5.605), extending the range of distribution and marketing (score 5.532), in collaboration with researchers in developing the quality of balta fish products to face competition (score of 5.437).

Judul: Kajian Usaha Pembesaran dan Pemasaran Ikan Lele serta Strategi Pengembanganya di UD Sumber Rezeki Parung, Jawa Barat
Abstrak: Consumption and demand for catfish has increased. These conditions open a big opportunities for catfish farming. To be successful in catfish farming, it requires technology and the enlargement of catfish market domination. The purpose of this study was to determine the magnification and technology marketing at UD Sumber Rezeki and get a new breakthrough in marketing efforts and the enlargement of catfish, determine the feasibility and efficiency of marketing efforts and the enlargement of catfish, find the prospect of catfish processed products, know the strengths, weaknesses, opportunities and threats in the enlargement and marketing of catfish and determine the strategy of business development and marketing of catfish enlargement on UD Sumber Rezeki. Technology production processes carried out by following the catfish aquaculture activities at UD Sumber Rezeki Parung, West Java, and then analyzed the feasibility of their business. The analisis through qualitative analysis, quantitative analysis of IFE (Internal Factor Evaluation) and External Factor Evaluation (EFE) Matrix IE and SWOT (Strengths, Weaknesses, Opportunities and Threats). Catfish farming in the UD Sumber Rezeki Parung, West Java feasible to be implemented with the value of Benefit / Cost (B / C) ratio> 1,26. Break Event Point (BEP) catfish production. Rp. 9631.76 per kg, NPV 14% on the value of Rp. 38,140,956, 17% IRR and PBP 3 years 9 months. Efficiency for catfish enlargement in UD Sumber Rezeki determined by the use of water by gravity, the use of probiotics to save time, use sinking feed and floating feed. Based on the IFE (2.83) and EFE (2.81), then the position at UD Sumber Rezeki phase of growth and stability and are in quadrant 5. Based on the analysis matrix and SWOT matrix IE, then the strategy for developing UD Sumber Rezeki, Parung, West Java are (1) market penetration by selling directly to end customer, (2) diversification of catfish products and (3) improve the competence of human resources. The conclusion of this study is the process of enlargement of catfish conducted by UD Sumber Rezeki good enough, the feasibility and efficient good enough but distribution channel catfish is too long. The most appropriate strategy for development is to penetrate and market development and product diversification. The advice is to develop more diversified products and observations in the distribution channel catfish.

Judul: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
