Abstract
The phenomenon of urban area development both physically and socially as the center of government in Sleman can indirectly cause an impact on the atmosphere. One of the impacts of the atmospheric change, the urban heat island, which is influenced by the physical and social development activities, is expanding. The research focuses on the study of surface urban heat island (SUHI) aimed at knowing the spatial distribution of the UHI intensity in Sleman Regency. The methods used in this research are the integration of remote sensing techniques and geographic information systems (GIS) using thermal bands of Landsat 8 OLI/TIRS and image statistical analysis using Buffer Boundary Analysis to identify the potential occurrence of SUHI in Sleman. The result of the processing shows the potential of high-intensity SUHI with a value of 2,001 °C-6,000 °C at a radius of 5,5 km from the city center and the intensity is getting down as the radius goes further from the city center. Administratively, the highest SUHI intensity relative to the district of Depok, Kalasan, and Ngemplak with SUHI intensity range of 1,5001 ° C – 6,000 °C, while the lowest SUHI intensity is relative to Kaliurang with SUHI intensity range of-10,000 °C – 0,000 °C
