Abstract

Drought problem is a routine problem occurring in several regions in Indonesia. Bekasi Regency is one of the regions impacted by drought every year. Such threat of drought occuring due to influence of climate is unavoidable. Nevertheless its impact can be minimized if we know the drought pattern of such a region. Meteorologically, drought monitoring can be conducted with various methods. One of the methods used is by knowing the SPI (Standardized Precipitation Index). SPI method is the rainfall unit occurring under normal condition in such a time scale. Beside meteorologically monitoring, it can also be monitored based on the spread of vegetation influencing the availability of water supply which can be seen from the NDVI (Normalized Difference Vegetation Index) value. The purpose of this research is to find the relation between the SPI (Standardized Precipitation Index) value and the NDVI (Normalized Difference Vegetation Index) value. The result of this research shows that there is a close relation between a region having such a high SPI value and NDVI value. But in a region having a low NDVI value, several regions have high SPI values.
