Land change modeler for predicting land cover change in Banjarmasin City, South Borneo (2014 - 2022)

Abstract

Land change is a phenomenon that often occurs in urban areas in the province. Banjarmasin city is one of several provinces that have experienced rapid land changes. Various government efforts such as buying rice fields from local residents have been sought by the local government to protect agricultural land. One of the spatial analyses that can be done to examine the phenomenon of land change is the modeling of geographic information systems and remote sensing. The method that can be used is IDRISI's Land Change Modeler. This modeling is based on 2014 and 2018 land cover data and several additional parameters such as road data, DEM and Euclidean distance to the road. Based on the modeling results from 2014-2018, Banjarmasin city developed changes in land from built up land of less than 800 hectares. Most land changes occur in the middle of the city. Based on the Markov Chain method by looking at land changes in the previous year, non-built land by 40% became built up land. Based on the predictive model of land cover change using the Marchov-Chain method, the development of built-up land in the Banjarmasin city is centered in the middle of the city and towards the north because there has been development of road access and housing development.
