Identification of land use change on rice fields in Tangerang District using landsat 8 imagery

Abstract

Tangerang District is a suburban area located around DKI Jakarta that has undergone significant development, resulting changes in natural resources. Rice fields are one of the natural resources in agriculture. The conversion of rice field areas into another land uses can indirectly cause several problems, such as food scarcity. The study aims to identify changes in the rice fields area of Tangerang District, using Landsat 8 imagery with supervised classification method. Based on the research findings, the rice fields in Tangerang District have transformed into residential areas, industrial zones, open fields, bodies of water, plantations, and green open spaces. The rice field area decreases every year. The conversion of rice fields into open land is the most dominant change due to the increasing demand for land for industrial and residential purposes in Tangerang District. The rice fields are drained before being converted into residential and industrial areas to compact the soil, ensuring it does not pose a threat to the construction on the land. The continuous and uncontrolled reduction in rice field areas can have an impact on food scarcity in Tangerang District.
