Land fires always occur every year in Banjarbaru, South Kalimantan. Land fires have been resolved but they continue to occur every dry season. The purpose of this study was to analyze the social vulnerability of land fires in Banjarbaru. This research method is to use the average population density weight (60%), the vulnerable group (40%) which consists of the sex ratio (10%), the poverty ratio (10%), the ratio of disabled people (10%) and the group age (10%). In addition, in-depth interviews were conducted with 11 respondents who were directly involved in the prevention and suppression of land fires. In general, the social vulnerability that is classified as high is Banjarbaru Selatan and Banjarbaru Utara Districts. High population density causes greater social vulnerability. However, public knowledge, including understanding of the causes and management of disasters, can cause this social vulnerability to decrease so that the risk is reduced.
