Abstract

Drought is an event that has a direct impact on several important sectors in Indonesia, including agriculture, forestry, plantations, and water resources. Geographic Information System has been developed with various methods. In addition, identification of drought areas is also carried out using the Regulation of the Head of the National Disaster Management Agency (Perka BNPB) Number 02 of 2012 concerning guidelines for disaster risk assessment.
