Abstrak: Business feasibility studies is one of the requirements to lodge financing to investors. Leleku.com sistem aims to help building the appropriate financial feasibility model so that the owner may submit financing toward investors, either individual investors or financial institutions. The sistem was made by using reference data from similar Small & Micro Enterprises (SME) gain through direct interviews, afterwards, a web-based application is made by using programming language, namely HTML, PHP, Javascipt, CSS, JQuery and using MySQL as the database. The modeling sistem is formed into two subsistem, covering database management subsistem ( DBMS ) and basic model management sub-sistem ( MBMS ). After being verified with researched data, the feasibility value for both SME was formed, with details as such : (1) For Karmina SME resulting NPV of Rp 469,884,900; 129% ROI; 2.99 of IP; 2.69 for B/C ratio; and Pay-back period after 10 months with profit of Rp 112,475,300/year. (2) For Al-Fardh SME resulting NPV of Rp 283,385,500; 149% ROI; 2.91 of IP; 2.66 for B/C ratio; and Pay-back period after 8 months with profit of Rp 68,323,700/year. From both name of SME, it appears that both SME deserved to be established and for investors, this is very promising because these businesses will gain big profit each year, which are Rp 112,475,300/year or Rp 9,372,900/month (Karmina SME) and Rp 68,323,700/year or Rp 5,693,600/month (Al-Fadh SME).

Abstrak: Shrimp is a product of fishery that most widely traded in the world. With a market share of approximately 14%, shrimp trade diversified from fresh shrimp to frozen shrimp and processed shrimp. In 2007, world demand for frozen shrimp reached 1,673,756 tons while in 2008 the world demand for shrimp declined 18.24%. Factors affecting the demand for shrimp are market conditions, quality of shrimp, and financial invesment. Investment in the shrimp agro-industry is still lower than other fisheries sector, because its having high risk. Decision support system of investment feasibility for Vaname shrimp agroindustry is a web based decision support system, which will assist the decision makers especially businessman and investor in making investment feasibility quickly, precisely, and accurately. Financing schemes that studied is the Islamic financing scheme, because the schemes more related to capacity and characteristic of small and medium enterpries, as well as public awareness of halal products usage. The main purpose of this research is to determine the pattern of Islamic financing schemes for the optimal of profit and loss sharing in mudharabah and musyarakah schemes. Especially to develop islamic financing model that can measure the financing benefit and feasibility level for the non interest based in Islamic financing businessman. Decision support system of investment feasibility for vaname shrimp with islamic financing schemes consists of two models, the first is shrimp cultivation and the second is for frozen shrimp agro-industry. Each model consist of several sub model, wich are financial analysis, analysis of the financing risk level, the minimum profit of investors analysis, analysis of the optimal revenue sharing, profit rate financing for entrepreneurs and investors, analysis of financing benefits level, and the last is analysis of the Islamic financing schemes feasibility. The finansial analysis used to know the value from parameter of invesment elegibility from finance aspect. The financing risk level used to determine the risk level from the scheme. The minimum profit of investors analysis used to look for the goals to advantage minimize which must be obtained by investors from the investment. The analysis of the optimal revenue sharing used to look for the optimal proportion of sharing holder which can be used from defrayal scheme. The profit rate financing for entrepreneurs and investors analysis used to know the benefit level for entrepreneur and LKS from a number of invesment. Analysis of financing benefits level used to determine the benefit level from defrayal scheme. And the Islamic financing schemes feasibility used to determine the feasibility level of the scheme. Vanamest.Org is the web based decision support system, which have some benefits, include easily in acces for make simulation can done by anywhere and anytime. In the other hands, this application is provided by the correction and update the data facility, so the user can earn easily manipulation of various data that becomes assumption in the feasibility scheme simulation. In Vanamest.Org, there are four especial sub menu, consist of sub financial input, risk evaluastion, benefit evaluation, and feasibility evaluation. Each sub menu representing the function of each sub model from database management system in Vanamest.Org. The simulation

Judul: Transisi Fasa Materi Hadronik ke Materi Kuark pada Inti Bintang Neutron.
Abstrak: Bintang neutron terdiri dari beberapa lapisan yang disusun oleh materi nuklir yang berbeda dengan kerapatan yang semakin tinggi ketika mendekati pusat bintang. Inti luar bintang neutron disusun oleh materi hadronik (nukleon, lepton, dan hyperon), sedangkan inti dalam bintang neutron disusun oleh kuark-kuark bebas (up, down, strange) yang saling berinteraksi. Tujuan penelitian ini adalah mempelajari bagaimana transisi dari inti luar ke inti dalam bintang neutron dengan menggunakan pendekatan RMF (Relativistic Mean Field) untuk materi hadronik dan CIDDM (Confined Isospin Density Dependent Mass) untuk materi kuark. Tekanan transisi diperoleh ketika potensial kimia barion materi hadronik dan materi kuark bernilai sama. Nilai tekanan transisi dengan parameter SU6-TM1 sekitar 87 MeV/fm3 dan diperoleh massa maksimum bintang neutron yaitu 1.92M dengan jari-jari sekitar 8.62 km. Nilai tekanan transisi dengan parameter SU6-G2 sekitar 53 MeV/fm3 dan massa maksimum bintang neutron yaitu 1.88M dengan jari-jari sekitar 8.16 km. Jenis transisi fasa adalah orde satu ditandai dengan diskontinuitas dalam kerapatan energi (adanya mixed phase). Parameter-parameter pada model nuklir yang digunakan menyebabkan perbedaan kekakuan persamaan keadaan (EOS) dari materi hadronik dan materi kuark sehingga nilai tekanan transisi dari fasa hadronik ke fasa kuark juga berbeda.
