Abstract

Crude Palm Oil is a commodity that is quite instrumental in the results of Indonesian plantations because it has a fairly large production yield and export quantity in meeting the needs of the world's crude palm oil. Indonesia is a country as the largest producer and exporter of crude palm oil in the world because Indonesia has vast plantations in tropical countries. This study aims to determine the effect of CPO production, CPO prices, CPO consumption levels, IDR / USD exchange rates on Indonesia's CPO export volume. The analytical method used in this research is to use quantitative methods using secondary data. To estimate the effect of independent variables on the dependent variable, multiple linear regression analysis is used with time series data between 2012-2016. The results showed that CPO production and the level of CPO consumption had a positive effect on Indonesia's CPO export volume, and the CPO price and IDR / USD exchange rate had a negative effect.

Abstract

Competition in the business world is getting tougher from year to year both within a country and abroad. There are a large number of companies competing with one another, especially entering the free market share in Asia, namely the Asean Economic Community (AEC). In the current development of modern economy, Indonesia is making efforts to increase its economic growth. For this, developments in any fields are made. Among others is the service industry such as accommodation, travel, and transportation services. Considering that Indonesia is a country comprised of many islands with a variety of natural beauty, it has the very potential for tourist resort attraction. This kind of thing leads to the growth of the Travel, tourism and hotel industry to support development of tourism. With such rapid service industry development, supported by promising business opportunities, investors for such sector are encouraged. The right way to reduce risk for investors interested is to develop a system for estimating the stock prices. Therefore, in this study, the high and low stock price estimation method applied for travel companies adopted developed Kalman Filter, a comparison of two Kalman Filter development methods, namely Extended Kalman Filter (EKF) and Fuzzy Kalman Filter (FKF) as a chart for investors to take into consideration in their investment decision making. The simulation results showed that the EKF method had higher accuracy than the FKF method with an error by the EKF of 3.5% and that by the FKF of 8.9%.
