Perimping sub-watershed is part of a mayor watershed in Bangka Regency where the expansion of tin mining was very high since 2001. However, this watershed still categorized as Priority II which mean it has to be maintained and retained for any changes. Environmental management program such as land conservation of post-tin mining area was contributed to maintained the condition around watershed which damaged by mining activity. This study aimed to identify the distribution of post-tin land conservation in Perimping sub-watershed based on land surface temperature and NDVI data in term of 2001, 2009, and 2017. Landsat 5 TM and Landsat 8 OLI/TIRS were used to estimate LST and NDVI. Google Earth imagery also used to identify the landcover change of land conservation. The result showed the average of LST around post-tin mining area were decreasing from high in 2001 (31°C-35°C) to moderate in 2017 (26°C-30°C). Yet the NDVI showed enhancement trend from low (0.1-0.25) to high (0.51-0.70). Both LST and NDVI distributed in the centre of Sub Perimping Watershed Area which indicate that the density of vegetation cover around post-tin area is increasing as the result of post-tin land reclamation and revegetation program.
