Spatial based mapping of londerang peatprotected revegetation

Abstract

The Londerang Peat Protected Forest is the largest protected peat forest in Jambi Province with 12, 500 hectares. In 2015 there was a peat forest fire that destroyed the existing vegetation. Based on the Moderate Resolution Imaging Spectroradiometer (MODIS) satellite, thousands of hotspots were observed from May to October. The condition of peat damage reaches 90%. Peat plays an important role in absorbing 75%of carbon so it should not be burned, dried, and used as plantation land. The purpose of the study was to determine changes in land cover, to determine the extent of revegetation, and to determine the area of unvegetated forest in the Londerang Peat Protected Forest area. The remote sensing method used is Image Classification assisted by ArcGIS Version 10.8 software with Landsat 8 satellite imagery. The analysis is carried out by making 20 color classifications on satellite image data, then the majority or pulling the minority pixel classes into the majority of pixel colors. From each code grid in the attribute table, the data are combined according to the landcover classification.The results of the spatial analysis of land cover In 2013-2018 there was very high forest degradation. In 2013 it was 2940.1 ha, in 2018 it was 191.3ha from the initial area of 12500 ha so that the Gonderang HLG was categorized as critical. Revegeted land is 354 ha with 164, 000 planted vegetation and the type of planted vegetation is endemic vegetation (Jelutung, swamp island, Gelam). The revegetation of the Londerang Peat Protection Forest has only been carried out for only 2.8% of the total land area.
