Mount Merapi is one of the most active volcanoes in Indonesia and is located in Magelang. Klakah village is located in the Boyolali regency and is included in the Merapi disaster prone area, while Gantang village is located in the Magelang regency, which is included in the safe zone, away from the threat of Merapi. The purpose of this study is to determine the implementation of the “sister village” policy in the event that Mount Merapi erupts in the Magelang and Boyolali districts. This research was conducted using qualitative methods with data obtained through interviews, observations, and documentation with five research subjects: Klakah village FPRB, Gantang village FPRB, Klakah-Gantang twin village facilitator, Magelang district BPBD, and Boyolali district BPBD. The results showed that based on the indicators of the sister village policy implementation, the sister village has been running since 2019, but there are several indicators that have not been implemented optimally. Thus, there needs to be better cooperation between the BPBD, sister village, and NGOs so that the implementation of the sister village policy can be carried out optimally. The implementation of the sister village policy resulted in the following proposals: (1) an information system, (2) resource assessment, (3) disposition in the form of a committee, and (4) a contingency plan structure.
