Judul: The econometric and forecasting models for Indonesia no-oil gas exports to the major markets
Abstrak: The decline in oil prices has led the changes of Indonesia trade from oil to non-oil exports since the mid 1980s. But some doubts arose about non-oil exports prospects in the future. On the other hand, Japan, Singapore and United States of America (USA) continued to be the major markets for Indonesia products. Thus, analyzing the changes of commodities, major markets and factors that influence the exports as well as forecasting the exports are needed in order to promote Indonesia exports in the future. As the first objective of this research, analyzing Indonesia exports by commodities had been done by descriptive approach. In 1985, non-oil/gas and oil/gas exports showed relatively the same amount. Then, the non-oil/gas exports showed increasing trend while the oil/gas exports was relatively stable. In 2001, the difference between total exports of oil/gas and non-oil/gas exports was significant. The total amount of non-oil/gas was 57917 millions of USD, while oil/gas was only 6905 millions of USD. This fact indicated that non-oil exports would have good prospects in the future. The second objective is to describe Indonesia exports performances to Japan, USA and Singapore had also been done by descriptive approach. Over the 1985-2002 period, exports volume to Japan, USA and Singapore increased. But the total share of these three countries decreased from around 77% in 1985 to 45% in 2002. This fact indicates that Indonesia has been successful in diversifying its exports markets. However, the trend of trade Intensity that expresses the strength of regional relationship was decreasing. The strongest Indonesia trade intensity among three countries was with Singapore, but the most stable was with USA. Although Indonesia trade intensity with Japan (TIJ) decreased, but TIJ-5.3 indicated that Japan still became important market for Indonesia products. Considering the importance of non-oil/gas exports, third objective was to analyze the variables that influence Indonesia non-oil/gas exports to Japan, Singapore and USA by using multiple linear regression model. The parameters were estimated by ordinary least squares method. Because of multicollinearity among independent variables, principal component analysis must be done. The analysis concluded that population, exchange rates and lagged export have significant and positive influences for Indonesia non-oil/gas exports to Singapore, USA and Japan. The external factors such as international interest rate (IRS and IRL) and trade intensity in most models are not significant. Foreign income is only significant in non-oil/gas exports to Singapore. The last objective of this research was to forecast Indonesia non-oil/gas exports for the next 10 years. Decomposition, Winter's method, trend analysis and ARIMA were compared to decide the best method for forecasting. Multiplicative decomposition method was chosen because generally it had the smallest MAPE, MAD and MSD. Generally, non-oil exports to Japan, Singapore and USA will increase. While exports to Japan and USA seemed to have similar trend, exports to Singapore showed different trend. The fluctuation of non-oil/gas exports to Japan and USA created a cycle every 3 years. that might because in every 3 years there are changes in Indonesia government's policy. The fluctuation of non-oil/gas exports to Singapore created a cycle every 6 years. It indicated

Judul: Analisis faktor-faktor yang mempengaruhi ekspor minyak sawit dan minyak inti sawit Indonesia
Abstrak: Indonesia as the biggest crude palm oil and palm kernel oil exporter in the world, can not continuosly keep on exporting the crude palm oil and palm kernel oil. Indonesia needs to develop the downstream production of crude palm oil and palm kernel oil industry to give the added value, to employ many labors and also as the environmental recovery function. Therefore, it’s needed a right policy from the government to support the downstream production of crude palm oil and palm kernel oil industry. The purposes of this research are: (1) to analyze the development of Indonesia’s palm oil export; (2) to analyze the development of Indonesia’s palm kernel oil export; (3) to analyze the affecting factors of Indonesia’s palm oil export; (4) to analyze the affecting factors of Indonesia’s palm kernel oil export. This research is using time series data from 1990-2011. The Indonesia’s crude palm oil and palm kernel oil export model was estimated by the doubled linear regresion with Ordinary Least Square (OLS) estimation method. Export models were divided into 6 single formulations, which are Indonesia’s palm oil export with destination country to India, Netherlands, and Singapore, also another single formulations of Indonesia’s palm kernel oil export with destination country to Malaysia, Netherlands and China. The result of this research indicates in a short period the tax rate would be an important instrument in order to limit the Indonesia’s palm and palm kernel oil export on the Indonesia’s downstream production of palm and palm kernel industry development. The facilities which must be built by the government in order to support the development of the downstream industry of crude palm oil and palm kernel oil are infrastructure development, application of tax holiday, and also by deleting the local regulation which blocks the development of the downstream industry of crude palm oil and palm kernel oil.
