“…Urban Cool Island's effectiveness is to create a balance between the environment and humans. Some studies on Urban Cool Island have been conducted in several cities in Indonesia, such as Salatiga and Yogyakarta [9,10]. Increasing the amount of green space can intensify UCI, which can lessen the likelihood that large cities will experience the UHI phenomenon.…”

Land use change is causing higher temperatures in urban centers, posing challenges for cities seeking livability and maintainability. Urban Cool Island can improve comfort in urban areas by directing microclimate and lowering temperature rise. The impact of Surface Urban Cool Island (SUCI) on a city’s ability to withstand urban microclimate phenomena is investigated in this study. This study aims to spatially analyze the spatial distribution, correlation, and impact of vegetation, surface temperature (LST), and built-up land density on Urban Cool Island Intensity. The method used was quantitative descriptive analysis of image data, including extraction of LST, NDVI, NDBI, and statistical analysis in the form of correlation and regression tests. The findings indicate that the Bandung City SUCI phenomena happened outside of the city at an intensity of -7.74°C to 0°C. Moderate vegetation density tends to be the cause of SUCI intensity, affecting 33.68%. Meanwhile, the density of built-up land has an effect of 43.18% on the intensity of SUCI. Correlation and regression analysis show that the relationship between SUCI intensity and NDVI is inversely proportional, while the relationship between NDBI and SUCI intensity is directly proportional. Denser buildings result in hotter SUCI intensity.
