Abstract

The increase in population occurs in Indonesia every year. This results in a high demand for space. Indramayu Regency is one of the regencies with high dynamics of land use and cover, which is indicated by an increase in residential area of 14.8 ha year-1 and a decrease in rice fields by an average of 13.9 ha year-1. This study aimed to identify the types of land use and cover in order to become a reference for analyzing the spatial dynamics of land use and cover in Indramayu Regency. Spatial dynamics of land use and cover were identified through Landsat 7 and Sentinel-2A which were then analyzed for overall accuracy, Kappa accuracy, validation using Google Earth, and overlays to produce maps of land use and cover dynamics in 2005, 2011 and 2021. The results showed that there are 8 classes of land use and cover in Indramayu Regency, namely forest, open land, dry land agriculture, dry land agriculture, mixed dry land, rice fields, settlements, ponds, water bodies. Paddy fields have a dominant area along the observation point (>61%) which are spread the central part of Indramayu Regency. The percentage of residential area increased by 0.8% from 33,724 ha (16.2%) to 35,377 ha (17.0%) in the period 2005-2021. Meanwhile, the percentage of pond area increased by 0.5% from 23,221 ha (11.1%) to 24,163 ha (11.6%) during that period. The increase in population and economic level are some of the factors causing the dynamics of land change in Indramayu Regency.
