This research discusses about mangrove density mapping and monitoring on tin mining area. The tin mining area refers to unconventional mining, which is a tin mining activity using simple mechanical instrument. Tin mining activity has been long existed in Bangka Belitung, conducted legally and illegally. Tin mining activity makes coastal supporting ecosystems such as mangrove cannot play their role normally. One of the regency in Bangka Belitung, which its coastal area is affected by

This research use Landsat data acquisition from year 1997, 2009 and 2014 through NDVI analysis. The result shows that tin mining activity in South Bangka coastal area causes reduction in mangrove density. The field studies indicated that 4 types of mangrove was found. The types of mangrove are Avicennia marina, Sonneratia caseolaris, Rhizopora mucronata, and Xylocarpus granatum. Mangrove management is needed in order to maintain the quality of coastal ecosystem. Moreover, the regulation and monitoring of the mining activity should be issued by the government to support environmental sustainability.
