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: Characteristic of Overshooting Top (OT) Based on  Himawari  8  Satellite  as  a  Convective  Cloud  Feature  that  Generates  Extreme Weather in the Java Island Region
Abstrak: Overshooting Top (OT) is a feature at the top of a convective cloud that is associated with extreme weather. Research on OT in tropical Indonesia is still very limited. The existence of geostationary satellites with wide area coverage and fast frequency observations is useful for observing the fast dynamics of the OT life cycle. Therefore, this study intends to analyze the relationship between OT and extreme weather, updraft and thermodynamic conditions of OT when extreme weather occurs, the best objective method for detecting OT in the day time and night time, and the spatiotemporal distribution of OT in the tropical region of Java Island during the 2018-2021 period. Based on visual analysis using visible channel and Himawari 8 sandwich products, 87% of extreme weather events in Java were accompanied by the appearance of OT. It indicates that the presence of the OT pattern is a convection cloud pattern or feature that is closely related to extreme weather events for the Java Island region. The existence of a time lag between the appearance of OT and extreme weather events on Java Island indicates that the OT of convection cloud can be used as a precursor or nowcasting for the appearance of extreme weather. Most of the convective cloud OT features during extreme weather events on Java Island have altitude that were only able to exceed the altitude of the equilibrium level and few were able to exceed the tropopause level of 9 km – 16 km. The difference in atmospheric conditions during extreme weather events on Java Island, which is in the tropics and subtropics, is a strong and unstable convective energy condition characterized by a larger CAPE, as well as unstable KI, LI, SI and TTI values. It is offset by kinematic factors in the form of a weak vertical wind shear (bulk wind shear 0-6 km) and a higher freezing point height. The difference between extreme weather events in the Java Island region and other tropical regions compared to subtropical regions is the strong updraft speed of convection clouds. The IRW Texture COMB algorithm based on the IRW-Texture Gradient modification and the COMB algorithm shows a significant increase in quality for detecting OT and non-OT pixels in Java. Rainy days with rainfall > 50 mm/day are very common in areas with an altitude of > 500 m. On the other hand, the level of convection activity which is indicated by the presence of OT and lightning is significantly reduced in this area. OT of convective clouds appear more frequently during the DJF season and less frequently during the JJA season. OT often appears during the day time and rarely at night time. Most OTs appear in the central part, away from the south and north coasts of Java Island during the day, while OTs that appear near the south and north coasts of Java Island can appear in the morning or afternoon.
