Judul: Faktor-faktor yang Mempengaruhi Permintaan Impor Buah-buahan dan Sayuran 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.

Judul: Penyelesaian Masalah Rotasi Aliran Fluida Kental Von Karman Menggunakan Metode Homotopi
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.
