Abstract: Abstract This article describes the pattern of changes in land use and land cover (LUC) and changes in land surface temperature (LST) in Lhokseumawe, an industrial city in Indonesia. Besides being a center of national activity in the industrial domain, this city was also named a special economic zone (SEZ). LUC is classified from satellite imagery from Landsat 5 (1998 and 2009) and Landsat 8 OLI/TIRS (2018), with six LUC categories: built-up area, vegetation, agriculture, bareland, wetland, and waterbody. There are three LUC maps produced. LSTs were also identified using the same imagery, resulting in 1998, 2009 and 2018 LST maps. The classification results show that the built-up area increased significantly. Monte Carlo Simulation was carried out to investigate the relationship between LUC and LST changes. From 1998 to 2009, the built-up area increased from 2025 ha to 3060.85 ha, while from 2009 to 2018, it increased from 3060.85 to 3783.63 ha. The LST in 1998 ranged from 23.28 to 33.21 °C, in 2009 from 23.28 to 35.48 °C, while in 2018 it ranged between 28.51 and 35.05 °C. The authors recommend that the LST variables be taken into account in sustainable urban planning. Policy makers and planners need to consider the importance of mitigating urban heat island (UHI), by suggesting a clustered greening concept at the urban and green material level in buildings and their environment.
