Abstract
Deli Serdang Regency is located in a strategic area because it surrounds Medan City. This study aimed to analyze changes in dryland forest land cover in Deli Serdang Regency, which is located in the up stream of the Belawan Watershed and the Deli Watershed for three time periods (2009, 2014, 2019) using the Geographical Information System (GIS). The results showed that during the period of 10 years 2009-2014-2009 the forest land cover in Deli Serdang Regency decreased from 19,517.58 ha in 2009 to 19,484.93 in 2014 and to 19,426.73 ha in 2019. Dryland forest land cover in several sub-districts in Deli Serdang Regency decreased. Hence, mixgardens, open land, cultivation, and shrubs become increased. In a period of 10 years, an area of 19,426.73 ha of dryland forest cover did not change, 26.80 ha become mixed gardens, 46.02 ha become open land, 5.85 ha become cultivation, and 12.18 ha become shrubs. There were five sub-districts with reduced forest land cover, namely: Gunung Meriah, Kutalimbaru, Sibolangit, STM Hilir, STM Hulu. Meanwhile, there were two sub-districts that have not changed, namely: Sibiru-biru and Bangun Purba.
