Abstrak: The purpose of this study was to determine the commodity exports of processed foods Indonesia and the factors that influence. The data used in this study is secondary data, the data in this study came from WITS (UNCOMTRADE), Central Bureau of Statistics Indonesia, the World Bank and CEPII. The data used is the data for 2005-2009. The method used in this research is a method of trade performance index and the method of static data using a panel gravity model. Object state in this study were the 10 major importers Indonesia for processed foods, namely: Australia, Japan, Malaysia, Nigeria, Philippina, Saudi Arabia, Singapore, Thailand United State of America and Vietnam. The results of this study were (1) processed food main commodities Indonesia exports are tobacco, cereals, tea and coffee and fish, (2) Commodities tobacco which has the largest export commodity tobacco not stemmed/stripped (240110), tobacco, partly or wholly stemmed/s (240120), cigarettes containing tobacco (240220). Commodities cereal that has the largest export commodity other pasta (190230), sweet biscuits; waffles and wafers (190530), other bread (190590). Commodities tea and coffee which has the largest export commodity black tea fermented (090230), other black tea fermented (090240), and coffea extracts, essences and concentrates (210111). As well as fish commodities that have the greatest export is commodities fish, whole or in pieces (160414), crab (160510), and shrimps and prawns (160520), (3) factors exports and GDP Per Capita Indonesia overall positive effect on exports of processed food commodities Indonesa. Factors importing countries population overall negative effect on exports of processed food commodities in Indonesia. GDP Per Capita Factor Importer countries, exchange rates and the overall ecodistance no significant effect on exports of processed food commodities in Indonesia.

Abstrak: Indonesia as a country with a large population has become one of the destination countries for trade. Free trade agreements among countries in exempting tariff duty of goods from overseas can cause excessive imports of agricultural commodities which increase from year to year. The purposes of this study were (1) To analyze the development of commodity imports of fruits and vegetables in Indonesia; and (2) To analyze the factors that affect the demand for imports of fruits and vegetables in Indonesia. The development of Indonesian imports of fruits and vegetables from the exporting countries during the period of 2006-2010 tended to increase. Overall, the factors that affect the demand for fruit imports to Indonesia included the imported fruit prices, index of industrial production, import lag, exchange rate of rupiah against the U.S. dollar and supply of mangoes at the Central Market of Keramat Jati. The economic distance variable did not significantly affect the demand for imported fruits in Indonesia. The factors that affected the demand for Indonesia as a whole included the imported vegetable prices, index of industrial production, U.S. dollar, import lag and economic distance.

Abstrak: Von Karman equation is an equation that describes fluid viscous flow induced by infinite disk rotation. By assuming steady flow and laminar, viscous incompressible fluid flow is represented in Von Karman equation by an angular velocity and the vertical direction velocity as the independent variables. Von Karman equation is a nonlinear problem that is solved using the homotopy method. The use of homotopy method is done by defining an homotopy function that requires auxiliary parameters to control the convergent region of the solution. The solution is a recursive formula with given initial conditions. Using software based-functional shows that velocity components converge to a value.
