Abstract

The increase in population is accompanied by equal distribution. In this context, population density of Jakarta is partly due to urbanization and long-term settlement. Therefore, this research is carried out to identify sub-districts experiencing the fastest population growth and the accommodated capacity. Population issues must be a central point of sustainable development allowing every resident and future generations to live healthily, prosperously, productively, and harmoniously with the environment. The relationship between population growth rate (PGR) and spatial aspects such as healthcare facilities, trade facilities, transportation facilities, government offices, education facilities, industry, and the availability of residential buildings from 2017 to 2022 is determined through Geographic Information System (GIS)-based analysis using statistical methods. The trend of PGR in East Jakarta sub-districts is high in the northwest and north, bordering Central and North Jakarta. Meanwhile, spatial aspects influencing high population growth are the availability of residential buildings and schools. Increased residential buildings and public schools in a sub-district due to the zoning policy in student enrollment are directly proportional to population growth.Received: 2024-07-27 Revised: 2024-10-18 Accepted: 2025-01-30 Published: 2025-02-12

Abstract

Urban areas often experience land cover changes. Banjarbaru is one of several cities in Indonesia that has experienced land changes. The relocation of the administrative center of Banjarmasin City to Banjarbaru City led to the development of settlements. One spatial analysis carried out to examine the phenomenon of land change is remote sensing techniques. The method that can be used is the Land Change Modeler from MOLUSCE in QGIS. This model uses the CAM (Cellular Automata Markov) method to identify land cover change and predict land cover distribution. CAM can understand and predict land change patterns by considering land use, vegetation, and cell spatial interactions. This modeling is based on land cover data for 2015 and 2020 and several supporting parameters such as DEM data and distance to roads. Based on the modeling results from 2015 and 2020, Banjarbaru City experienced a change in built-up land, with most of it occurring in the center of Banjarbaru City. Based on the Markov Chain method by looking at land changes in the previous year, the development of built-up land increased by about 8% of the Banjarbaru City area of 32917.41 hectares. Based on the prediction results, the development of built-up land is centered in the middle of Banjarbaru City, such as North and South Banjarbaru Districts, due to the development of residential development.Keywords: Land Cover, Land Change Modeller, Cellular Automata, Markov Chain
