Analisis Perubahan Kerapatan Vegetasi Hutan Jati Dengan Metode Indeks Vegetasi Ndvi (Studi Kasus: Kawasan KPH Randublatung Blora)

Abstract

Most of the area Blora Regency is covered by forest, especially Jati forests. Unity Forest Perhutani Officials (KPH) Randublatung is the largest KPH in the Blora Regency. Illegal logging in the KPH Randublatung result in less quantity of Jati trees and large of forest vegetation. As a result of the reduced Jati forest vegetation can cause errotic seasonal changes and some animal loss their cage.This study aims to determine the change in the density of vegetation and extensive Jati forests in the KPH Randublatung. The method used to determine the density of the forest vegetation to determine the identity that is based on the analysis of vegetation index NDVI (Normalized Difference Vegetation Index) using image Landsat 7 ETM + recording in 2000 and 2011.Based on the results of data processing, in 2000 area forest vegetation in the KPH Randubltung of 25.528.33 ha, with does not too heavy density has the highest value obtained from the analysis of vegetation index NDVI is an area of 10.815,33 ha. Meanwhile in 2011 area forest vegetation in the KPH Randublatung of 12.451,37 ha, with rare densities has highest value area of 5.105,77 ha. Thus from 2000 to 2011 land cover Jati forest vegetation in the KPH Randublatung changing area of 13.076,96 ha
