The city of Cilegon is experiencing a fairly rapid development of built-up areas, which has an impact on the development of built-up areas in the surrounding suburbs. Changes in vegetation land cover to built-up land have a direct impact on increasing surface temperatures, resulting in the Surface Urban Heat Island (SUHI) phenomenon, a phenomenon in which urban areas have a higher surface temperature than their surroundings. This study aims to examine the potential for developing green infrastructure as an effort to mitigate the Surface Urban Heat Island (SUHI) phenomenon. This study uses a mix of methods between quantitative and qualitative analysis. To identify the potential for green infrastructure, identification of development principles and typologies of green infrastructure is carried out through content analysis, the potential for green infrastructure development and the potential reduction of the SUHI Surface Urban Heat Island area through spatial analysis. This study identifies the influence of built-up areas on the development of SUHI-affected areas using spatial analysis and simple linear regression. This study also predicts the distribution of SUHI Surface Urban Heat Island affected areas in Cilegon City in 2040 through spatial analysis of Cellular Automata. The results showed that the development of built-up areas in Cilegon City during the 2003-2020 period increased by 48%, where industrial areas had a higher development rate than other regions. The land surface temperature of Cilegon City has increased by 7.5 Celsius in the 2003-2020 period. Industrial area experienced a higher increase in surface temperature compared to the surrounding area. The increase in average temperature was also followed by an increase in the area affected by Surface Urban Heat Island (SUHI) in the 2003-2020 period, which experienced an increase of 5511.9 hectares or 33.9% of the total area. The density of built-up land has a positive effect on increasing surface temperature, and is inversely proportional to the value of the vegetation density index which has a negative effect on surface temperature. Surface Urban Heat Island The direction of the Cilegon City spatial pattern has an impact on increasing the SUHI area, which increases by 8034 Ha in 2040. The principle of developing green infrastructure is based on the characteristics of Cilegon City, namely connectivity, conservation framework, multifunction, multiscale, continuity. The potential area for green infrastructure development is 9,344.44 ha or 57.5% of the total area. The potential for green infrastructure development has an impact on the potential reduction of the SUHI Surface Urban Heat Island affected area reaching 10033.3 Ha
