Abstract
Drought hazard index monitoring is important in the process of disaster risk reduction, as part of efforts to control drought. The purpose of this study was to determine the drought index based on precipitation. The location of this study is in the East Java region. The method used in the research is the Standardized Precipitation Index (SPI) method. The data needed is rainfall data obtained from the TRMM satellite. The data is then analyzed using R to obtain a drought index value. The results showed that Banyuwangi Regency became a district with a moderate drought hazard index with the highest value, which is 52.3% or 0.523 on a scale of 0-1 in accordance with SPI. Mojokerto City is a district with a low drought hazard index with the lowest value, which is 28.4% or 0.284 on a scale of 0-1 according to SPI.
