Abstract
The protected forest of Gunung Sebatung is located on Laut Island, one of the small islands in the province of
South Kalimantan. Surrounding protected forests there are 14 villages and Kotabaru district centers city centers
in Kotabaru district. They carry out cultivation activities in the area claimed to be hereditary activities to meet
daily needs, so that they cannot be stopped. The problem that has occurred to date is deforestation in the form of
increasing land tenure and illegal logging, so that the function of forests as a buffer of life does not function
optimally. The purpose of this study was to estimate the amount of deforestation in protected forests of Gunung
Sebatung. The research method used is remote sensing of SPOT satellite in 2010 and 2018 and field survey using
transect method. The results of this study indicate that the protected forests of Gunung Sebatung from an area of
7,561.95 ha, around 4,900.47 ha (of 64.8%) are still in the form of secondary natural forests whose species
composition describes the characteristics of Kalimantan's tropical rainforest, and the remaining around 2,661.5
ha (of 35.2%) have changed their land cover for agricultural cultivation and mixed gardens. In 2010 the measured
forest area was 5,759.46 ha and in 2018 measured 4,900.47 ha, resulting in deforestation covering 858.99 ha or
1.86% per year. The floristic composition found was from Dipterocarpaceae family, namely: Shorea montigena,
Shorea leprosula, Shorea multiflora, Dipterocarpus spp and Non Dipterocarpaceae such as Eusideroxylon
zwagery, Vitex pubescens and other natural species. There are still quite a lot of trees > 50 cm in diameter.
