Disaster readiness management is the main thing that the government must pay attention to in order to obtain methods as material for evaluating regional disaster management and management. The Regional Disaster Management Agency (BPBD) is one of the stakeholders who play an active role and is fully responsible for disaster preparedness in the region, so the Sleman BPBD readiness is crucial in handling and managing the eruption of Mount Merapi. So far, no assessment regarding this readiness has been carried out. This study aims to measure and map BPBD Sleman's readiness to handle and manage Mount Merapi's eruption in Yogyakarta Province. The variables used in this study are variables from the Sendai Framework and the National Disaster Management Plan. This study uses the Nominal Group Technique method for variable validation and the Analytic Hierarchy Process for variable weighting. It then changes the scale from ordinal to interval using the Method of Successive Interval. The next step is to calculate the readiness index by multiplying the results of the indicator assessment by weight. Data processing is carried out using 11 main criteria and 43 indicators. The results of the calculation of the readiness index show that the readiness index value of the Sleman BPBD is 55.362. Based on the index categorization and readiness status, the readiness of Sleman BPBD is in the ready category. Recommendations for improvement are made to indicators with assessment results that have low scores or indexes.
