Abstract

Rawapening Lake has specific biogeophysical form, biodiversity potential and socioeconomic also ecological functions which are very important for people's lives and the surrounding environment. Even so, the facts showed that the activities of the population around Rawapening are growing so that problems arise in the form of environmental degradation that has continued to the present. This study aims to determine the development of land cover in the Rawapening River catchment starting from 2000, 2010 and 2019 on the sedimentation rate that occurred in Rawapening Lake. This study applies a Spatialecological approach by using multi-temporal remote sensing image data accompanied by field surveys and secondary data from related agencies. The tools used in this study are image processing software and Global Positioning System (GPS), while the data used utilizes RBI maps, Landsat 7 Satellite Images in 2010 and
Landsat 8 in 2019. The results showed an increase in the area of developed land by 1,520.54 ha in the period 2000 - 2010 and experienced an increase again in 2019 amounting to 1,330.96 ha. The increase in the area of land developed was due to land conversion, which was largely derived from vegetation cover in the water catchment area (DTA) of Rawapening, where the impact caused by the change in land cover increased the rate of sedimentation that occurred in Rawapening Lake. Therefore, it is necessary to limit the transfer of land functions in the DTA of Rawapening so that it does not cause siltation in Rawapening Lake in the future.
