Abstract


Land management especially lands not following the rules, can cause damage/change in soil properties, impacting the disruption of biomass production. The lack of available data regarding land and land damage, especially in Tanjungpinang City, has resulted in less than optimal supervision and control over land management. Mapping the condition of land damage is necessary to exercise control over land management. This research aims to assess land damage for biomass production in Tanjungpinang City, Riau Archipelago. Land damage can be modelled by scoring and overlaying four parameters, namely land use, slope, soil type, and rainfall, producing a tentative map of potential land damage. Next, a tentative map of land damage is corrected using a field survey. Field surveys are used to measure the standard criteria for land damage according to Government Regulation No. 150 of 2000. The results show that the criteria for land damage in Tanjungpinang City are light and moderate. The criteria for moderate damage have the most extensive area spread over Dompak Sub-District, Batu Sembilan, Melayu City Plate, Bukit Cermin, West Tanjungpinang, East Tanjungpinang, Kampung Baru, and Tanjung Ayun Sakti. The main limiting factors that limit land use in Tanjungpinang City are permeability, surface rocks, and redox reaction
