[ABSTRACT]Rice is one of the most important agricultural crops in Indonesia and also a primary food resource for more than three billion people in the world. However, because of a worldwide serious problem on food shortages due to climate change, it is necessary to evaluate the potential of rice production and estimate rice yield in Indonesia. Cianjur, a study area, is located in the West Java, Indonesia, at 7°03' S latitude and 106°60' E longitude. This area is famous for the rice production and is one of areas where the decrease of agricultural productivity is much concerned. Satellite remote sensing has been used widely and extensively and is now recognized as a powerful and effective tool for monitoring rice growth and the rice production. In this study, images of leaf area index (LAI) by Moderate Resolution Imaging Spectroradiometer (MODIS) acquired from 2003 to 2008 were used to evaluate the rice growth and also construct an equation of the rice yield per unit of a paddy field in Cianjur. As a result, it is suggested that a weekly change of LAI indicates two times of rice production in a year, and the average LAI of the 2 times production is correlated with the rice yield per unit (r=0.527, p<0.05). Thus, this indicates that the rice yield per unit can be estimated through the following equation: y = 0.632479x + 3.049962 , where y is the rice yield per unit size of a paddy field and x is the average LAI of 2 times production, and the standard error of estimation is 0.77.
