ANALYSIS OF LAND USE CHANGES IN SUNGAI BEREMAS DISTRICT, PASAMAN BARAT DISTRICT YEAR 2000, 2010 AND 2020

Abstract

This study aims to find out 1) determine changes in land use in 2000, 2010 and 2020 in Sungai Beremas District, 2) determine predictions of changes in land use in 2030 in Sungai Beremas District. This type of research uses quantitative methods. The type of data in this study is primary data obtained from observations while secondary data used Landsat imagery sourced from the EarthExplorer website and shapefile data for the research administration area from BPN Pasaman Barat. The analysis technique used to determine changes in land use/cover is supervised classification using Envi 5.1, and to determine predictions of changes in land use/cover using the Markov Chain and Celluller Automata using the Idrisi Terrset application. The results showed that changes in land use/cover that occurred in Sungai Beremas District experienced the most significant changes, namely in forests and plantations, while changes in land use/cover that were not so significant were water bodies. Changes in land use/cover in forests have always decreased, namely in 2000 it was 24,264 Ha, in 2010 it had decreased to 19,816 Ha, in 2020 it continued to decrease to 13,552 Ha, and in 2030 the area of  forest in Sungai Beremas District is predicted to continue to decrease until it reaches 10,260 Ha. The use of plantation land has always increased, namely in 2000 covering an area of  6,184 Ha, in 2010 it has increased to 8,289 Ha, in 2020 it continues to increase to 13,056 Ha, and in 2030 the plantation area in Sungai Beremas District is predicted to reach 17,190 Ha, while the body of water will not change, even in 2030.
