Built-Up Area Changes, Spatial Pattern and Urban Sprawling in Kedungsepur Metropolitan Area

Abstract

Kedungsepur is a metropolitan city in Indonesia designated as a national strategic area. With the increasing population, the demand for land for urban activities has also risen, leading to the conversion of undeveloped land into built-up areas. However, few studies have measured land use changes in developing countries, especially in metropolitan areas. This article delves deeper into this subject. While the development of big cities in Indonesia has led to physical expansion, uncontrolled growth has caused urban sprawl in the urban fringe of the core city and suburban areas, as well as in the metropolitan context comprising core and satellite cities. Planning the city's physical growth is crucial to prevent uncontrolled and sporadic urban sprawl. Urban sprawl studies in Indonesian metropolitan areas, particularly those using high-resolution satellite images, are still uncommon. This article uses Sentinel 2A imagery to qualitatively interpret urban sprawl patterns and quantitatively analyze spatial patterns using the nearest neighborhood analysis technique in ArcGIS software. The results reveal that the Kedungsepur Metropolitan Area is experiencing a sprawling leapfrog type of urban sprawl. These findings are crucial for monitoring and improving urban spatial planning in the future.
