The conservation of mangrove forests in Bosua Village, Mentawai, is very important given their vital function in mitigating natural disasters such as floods, coastal erosion, and tsunamis. Mangrove forests act as wave barriers and shoreline protectors, as well as important habitats for various marine species that support the local economy through sustainable fisheries. Therefore, increasing public awareness of the importance of mangrove conservation is crucial. The aim of this activity is to educate and empower the community to actively participate in conservation efforts, which involves mangrove planting mutual cooperation activities, the formation of environmental awareness groups, and collaboration with NGOs, government, and academics. The activity methods used are providing education using lectures, educational videos, distributing flyers and posters and planting mangrove seedlings on the beach. To measure the success of education, pre tests and post tests were used to measure the level of community knowledge about mangrove forest conservation. The results of this activity increased community knowledge by 6.13, from 12.53 (before education) to 18.66 (after education). The T-test results obtained a p-value <0.001. That is, statistically it can be concluded that there is a significant average difference between community knowledge before and after education. The conclusion of this activity is that after being given education, the average community has increased knowledge about mangrove forest conservation as an effort to reduce disaster risk. It is hoped that the community and local government will be able to maintain and preserve mangrove forests in the Bosua Village area as a form of effort in disaster mitigation.
