Monitoring 20 Years of Land Cover Change Dynamics in The Satellite Cities of Jakarta, Indonesia

Abstract

Abstract As the capital city of Indonesia, Jakarta has eight satellite cities as the supporting areas, namely Bogor Regency, Bogor City, Depok City, Tangerang City, Tangerang Regency, South Tangerang City, Bekasi City, and Bekasi Regency. The rapid urbanization in Jakarta is driving the growth of these areas. One of the impacts of urban growth is the land cover change that can be observed through multitemporal satellite imagery. This study analyses the land cover change within 20 years in urban and non-urban areas. The data used are Landsat satellite imagery and Indonesian base maps validated by ESRI World Imagery. In this study, satellite imagery is processed into predetermined classes. The analysis process by comparing land cover classes between 2001 and 2021 and calculating the area of each class in each regency/city. The results show that dense and evenly distributed urban growth occurs throughout the “City” area. Attention must be given to the government of Bekasi City, Tangerang City, South Tangerang City, and Depok City because the built area already exceeds 70% of the city area.
