Abstract
This study attempts to map drought and analyze rice productivity of Rain Fed Rice Fields in Kabupaten Indramayu West Java. The methodology which used in this research is descriptive. Arc GIS 10.2 is used for mapping the SPI, and it will be used to analyze rice productivity of Rain-Fed Rice Fields in Kecamatan Indramayu West Java. The result showed that District Indramayu experienced, the drought began in May to October. The area that is prone to drought in the same period of the last ten years is Anjatan regions with 33 times scene drought. August experienced scene drought most. District of Indramayu has planting patterns in the two times rice planting season and various kind of crops. The growing season of rice starts on November-December-January and the second growing season starts on May-June-July. The Pattern of productivity from the first planting period to the second planting second on average for ten years showed a decline. The pattern is followed with dryness index. The increased productivity only happen in growing season in 2007, 2008, 2011, and 2013 in 10 years.
