Gresik is a regency in East Java that has the largest industrial area in East Java. With an industrial area of 2326.2 Ha, Gresik Regency is ranked as the first regency with the largest industrial area in East Java. Located on the North Coast of Java, Gresik has great potential for port and trade activities. The north of Gresik borders the Java Sea and the east borders the Madura Strait and Surabaya City. This condition also made the government inaugurate Gresik as the location of the Java Integrated Industrial and Ports Estate (KEK JIIPE) special economic zone.

Along with the establishment of KEK JIIPE, there tends to be changes in land cover, from vegetated areas to built-up areas. The development process will affect the land area needed to support daily activities and affect the temperature which triggers the urban heat island phenomenon.

This study aims to determine whether the land cover characteristics of Gresik Regency are associated with higher or lower surface temperatures. The urban heat island phenomenon is then analyzed using a remote sensing data approach through several extractions, namely the use of supervised classification, NDVI (Normalized Difference Vegetation Index) and LST (Land Surface Temperature). Data processing was carried out using Landsat 8 oil satellite images in 2023, 2022, 2021 and 2019. The processing results in the form of surface temperature distribution were then correlated with the value of vegetation index and land cover change using a simple regression test. The output and target achievement of this research is the proceedings of the ICSSL FISH international seminar in 2023
