ABSTRACT

The high population in urban areas makes the area of green open space decrease as the time goes by. Jakarta Megapolitan Area (Jabodetabek) is one of the megapolitans that are affected. The reduction of green open spaces in this area slowly impacts temperatures increase in urban areas or commonly called urban heat islands (UHI). IPB University and the University of Indonesia are two campuses located in the Jabodetabek and have contributed to urban green open space. The study was conducted to see the greenness index (NDVI) effect and size of green open space in reducing air temperature in both campuses. QGIS software was used to obtain the total area of each GOS sample. This software was also used to obtain the NDVI and LST value. NDVI values were used to analyze the relationship between vegetation coverage with LST. From the result, the comparison of NDVI and LST values in the both campuses did not show a strong correlation. In IPB University, the comparison between GOS size and LST value showed a weak negative correlation with R2 0.35. In contrast, in the University of Indonesia, GOS Size and LST value showed a strong negative correlation.
