ANALISIS PERUBAHAN PENGGUNAAN LAHAN DAERAH TANGKAPAN AIR DANAU KERINCI (Land Use Change Analysis in The Kerinci Lake Catchment Area)

Abstract

Lake Kerinci is one of the 15 national priority lakes. In general, residents in this area carry out agricultural or plantation activities without applying conservation principles, resulting in a decrease in the carrying capacity of the Catchment Area (DTA). In addition, DTA Lake Kerinci has also experienced an increase in population, thus encouraging land-use changes. This study aims to analyze land-use changes in DTA Lake Kerinci. Analysis of land-use change analysis uses Landsat imagery 5 TM for 2009 and Landsat imagery 8 OLI-TIRS for 2019 using the guided classification method (Maximum Likelihood Classification/MLC). The accuracy of the image interpretation results is carried out through the Kappa accuracy test. Interpretation of land-use imagery and classification have relatively high accuracy with a kappa value of 78.67% (good) on land use in 2009, 83.30% (almost perfect) on land use in 2019, with an average Kappa Accuracy (KA) of 79.63%. Land-use changes in Lake Kerinci DTA for the 2009-2019 period experienced a significant increase in the area of dry agricultural land by 13% or 13,151.05 ha and a decrease in primary forest area by 6.76% or 6,834.13 ha.
