Abstract
Cianjur District is one of the areas in Cianjur Regency, West Java, Indonesia, which is the center of community activities. These community activities allow the Cianjur District area to experience massive urbanization and development to meet the growing demand for land increase. This research aims to analyze the spatial distribution of urban phenomena Heat Island (UHI) in Cianjur District and the association between LST and NDVI in Cianjur District. This research uses Landsat 8 data to analyze UHI with LST values. Correlation analysis was also performed to see the association between LST and vegetation density. Based on LST data processing, the temperature in 2014 and 2021 showed that 2014 10 Villages had a surface temperature above 30°C, so they experienced the UHI Phenomenon. The village comprises Bojongherang, Muka, Pamoyanan, Solokpandan, Sayang, Sawahgede, Mekarsari, Limbangansari, Nagrak, and Sukamaju. In 2021, the UHI phenomenon will expand to all villages. LST in Cianjur Regency has a robust negative correlation with NDVI, both in 2014 and 2021. So, the more dense vegetation, the lower is LST, and vice versa.
