The contribution of housing area to land surface temperature in Bandung

Abstract

Following the development of built-up areas in Bandung predominantly for housing purposes, the land surface temperature (LST) in the region has increased significantly. In urban planning, particularly in housing, environmental aspects related to LST have yet to be widely considered. The aim of this study is to identify the relationship between housing densities and LST. The information regarding elevation, density, LST and tree cover (vegetation coverage) in housing areas in Bandung have been collected. Landsat 8 satellite images were used to assess LST levels and to calculate the normalised difference in vegetation index (NDVI). Statistical analyses have been conducted to determine whether the NDVI and the housing density are factors that influence LST values. A correlation analysis demonstrates a strong inverse relationship between LST and NDVI while controlling for elevation of the housing area, with Pearson correlations of -0.575, -0.612 and -0.754. Meanwhile, an ANOVA test showed that LST comparisons at each elevation were statistically significant (p<0.05), it presents the idea that LSTs for highdensity housing and medium-density housing have significant differences. The statistical test results indicate that the housing densities and the lack of urban tree cover contributes to LST. These findings are an invaluable source for spatial planning in housing areas and support sustainable development in Bandung city.
