Judul: Rencana Bisnis Industri Manisan Stroberi
Abstrak: Strawberries (Fragaria vesca) are the fruit of herbaceous plants which were first discovered in Chile, the United States. Fruit confectionery or candied fruit is fruit preserved with sugar. Candied processing can be grouped into wet and dry process. The different types of wet and dry candied views of the process after a soaking in sugar solution. The production of fruit confectionery is by soaking (impregnation of sugar into fruit), washing, and drying process. Candied strawberries business used the concept of a business plan. Selection of business due to potential prospects and a good target market. One thing that became surplus of this new business is candied strawberries are still scarce in the community so that it can be an alternative to snacks that are healthy and delicious.To open greater interest of investment in agro-industries, particularly commodity strawberries, we need a tool that can easily provide information about the commodity and can help potential investors to determine the appropriate business planning to run in this field. The design process undertaken to determine the Business Plan: Net Present Value (NPV) of business, B / C Ratio, IRR, Pay Back Period (PBP) and Break Even Point, which will determine the business whether viable to run or not. The process of calculation are financial analysis / feasibility studies, market potential of candied strawberry industry are still open, the location chosen for this industry is Ciwidey with certain considerations. Based on the calculation of costs and production capacity, the sale price of candied strawberries were Rp 125.000/kg. Total production capacity of 13.520 kg / year with a workforce of 12 people. Based on the analysis of financially, this project NPV Rp. 1.070.841.068, -; IRR at 33%; B / C ratio of 2.4, and PBP for 4 years and 4 months so it can be concluded that the Candied StrawberriesIndustry is worth to establish. Based on the sensitivity analysis, the industry will be established if it is not feasible to achieve price increases of raw materials for 22.3% or decline in selling prices by 12.4%

Judul: Optimalisasi Produksi Stroberi dan Sayuran Pada Puncak Berry Farm Agrowisata Cipanas, Kabupaten Cianjur, Provinsi Jawa Barat
Abstrak: Puncak Berry Farm is an agribussiness company in west java that developed the business of strowberries and vegetables cultivating for the needs of its agrotourims. The study aimed to analyze the combination of productions that bring in the optimal return. The analysis method that used in this study is Linnear Programming (LP) which from the models of goals and abstacles function. The result shows that the residual value of polybag that used for production, in the actual condition the value greater that zero, while the residual value on the optimal condition is zero. In the other side, the resource on the optimal condition shows the excess, it seen from the slack or surplus value that greater that zero.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
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.
