Perubahan penggunaan lahan dan pengaruhnya terhadap daya dukung lahan untuk mendukung perencanaan penataan ruang (Studi kasus di kota Bima provinsi Nusa Tenggara Barat)
Abstract
In regional development, there are at least 3 aspects that affect each other: land cover/land use (LCLU), environmental carrying capacity, and socioeconomic factors, including population, economic activity development, and institutional. The aims of this study are: (1) to identify land capability, (2) to identify the change of LCLU in the Kota Bima Municipality, (3) to evaluate the suitability of land use with land capability, (4) to identify the status of the land carrying capacity based on productivity in 2005 and 2010, and (5) to set a space pattern based on environmental carrying capacity. The analytical method used are onscreen digitizing to identificate land cover/land use (LCLU). The analytical method used consisted of: operating attributes and processing thematic maps using ArcGIS 9.3, Location Quotient analysis, and regression analysis with binomial logit model. The result in land capability aspect, most areas in Kota Bima Municipality belong to Class IV (l, e), covering 28,5% of the municipality areas, and there is no Class I. During 2005 to 2010 there is a change of LCLU in Kota Bima Municipality, covering an area of 6.692 hectares or 30,6% of the area of Kota Bima Municipality. Trends in change of LCLU that occurred was the forest to cropland and cropland into the settlements. Cultivated land area has increased significantly, effects on the increased value of production. This causes changes in the status of land carrying capacity based on productivity, which is in 2005 the status of land carrying capacity is deficit, but by 2010 the status of the land carrying capacity is surplus. However, increasing of land carrying capacity status is also followed by increasing of land use that is not suitable based on land capability. The suitabilty of land cover regarding to land capabilty show that in 2005 there is 3,7% areas categorized as not suitable, and in 2010 there is 7,4% area categorized as not suitable. Based on land capability, there is 16.342 hectares or 74,8% of the area that can be used as cultivation land, 2.752 hectares or 21,5% of the area can be used as forest, and 2.768 hectares or 12,7% of the area should serve as a protected area.
