Abstract

Drought is one of the disasters that shows the reduced availability of water to the need. Drought has a very large impact on human life, one of which is the availability of much-needed water supply in all sektor.Agricultural sector is the worst affected by drought because weather and climate have a significant relationship to plantingn. Rice plants are crops that urgently need sufficient water. If the rice plant lacks water, it will affect planting patterns and can also cause crop failure. Musi Banyuasin Regency, which is the number 4 largest rice producer in South Sumatra Province, is very necessary to overcome the impact of this drought so that threats to food security in South Sumatra Province do not occur. This study aims to find out which areas are endemic to drought in Musi Banyuasin Regency. In identifying drought using secondary data, namely rainfall with the SPI (Stadardized Precipitation Index) analysis method for a period of 3 months, then the results of the SPI calculation are interpreted into a drought distribution map presented in the form of color gradations. The results of this study show that the incidence of drought in Musi Banyuasin Regency varies from district to sub-district, in this case there are 3 categories, namely from the lowest, moderate, to the highest. The highest drought category is spread across 6 districts in Musi Banyuasin Regency. Then the moderate drought category is spread across 5 sub-districts while the lowest drought category is spread across 4 sub-districts. The re-period of drought events in Musi Banyuasin Regency is different, the fastest occurrence is 2 years, the longest is 3 years and the average is 2 years.
