Abstract

The structure of a city often changes in line with population growth and urbanization, which requires the development of infrastructure to meet people’s living needs. Urban heat islands (UHIs) are a phenomenon that occurs in urban areas experiencing much warmer temperatures than the surrounding rural areas. Double to the temperature rising as the result of climate change, UHIs will be a threat to the people. This study has been conducted in three locations: Bandar Lampung (the capital city of Lampung Province), Metro (a regency capital city), and Karawang (an industrial city in West Java) for the years of 2014, 2019, dan 2024. The purpose of this study is to prove that temperature rise is related to land cover change, and the UHI concept could be used as a tool to evaluate cities' segmentation planning. Data collection was carried out through a remote sensing method. Landsat 8 OLI/TIRS images processed in ArcGIS through radiometric correction, clipping, and result in thermally based temperature. The results are presented in LST, NDVI, and NDBI maps. UHI patterns were clearly shown in all three locations, with differences in their distribution, and the UHI reflected the city's segmentation. Therefore, the UHI concept should be applied in planning city development.
