PENENTUAN STATUS DAYA DUKUNG LINGKUNGAN BERBASIS KESESUAIAN LAHAN DAN KESEIMBANGAN LAHAN DI KOTA BATU, JAWA TIMUR, INDONESIA

Abstract

The shift of land function that beyond the environment support has decreased the environment quality, such as flood, and it has increased the sedimentation as well. In order to control the area development, implementation of the environment support is really important to be counted on. Determination of the environment support includes the supports that based on land capability and land balance. Objectives of the research were 1) to evaluate the land use toward the environment support that based on two basis for the existing land use in 2010, 2) to study and predict the environment support status for the next 20 years (in 2030) based on calculation of the prediction and the Regional Layout Design. The analysis method of the research was descriptive by describing results of the support calculation through the support status of both surplus and deficit. Results of the research showed that width of the existing land use, which was not conformed to the land capability class was 25.67%, while the inconformity based on the space layout design of land use was 32.05%. Calculation of land balance, which shows the results that the status in 2012 and prediction in 2031 are still surplus and safe.
