Forest and land fires are disasters that often occur every dry season in Kalimantan. Fire information often does not reach the public, so disaster communication is urgently needed. Disaster communication is a very important parameter in disaster mitigation so it needs to be improved and requires collaboration and coordination of various stakeholders, such as government, companies, media, scientists, advocacy groups, and the community. There has not been much research on communication with the theme of fire, so more in-depth research is needed. The purpose of this research is to find out how to Optimize Disaster Communication for Future Fires Mitigation”. Research on disaster communication was carried out in the location of the new state capital, East Kalimantan. The research used the descriptive-analytic method to identify the research area and collect secondary data. Disaster communication is an activity carried out by several parties, in this case, the authorities in preventing and overcoming the negative impacts that may arise due to fires. The results showed that the disaster management agency in East Kalimantan was the Regional Disaster Management Agency (BPBD). In mitigating fire disasters the community is known to use social media, namely Instagram, Twitter, and Facebook.
