Abstract

Urban Heat Island phenomenon (UHI) is one of the city micro-climate phenomenon that mostly hit many big cities in the World, including Makassar, Indonesia. Therefore, this study aimed to analyze the phenomenon of UHI and UHII in Makassar and the surrounding areas. The method used in this study is the analysis of primary data through measurements taken directly to the varied station locations. The measurements are determined by purposive sampling toward the variety of different land uses. The measurements were taken at 11:00 am until 1:00 pm Central Indonesian Time (WITA) and at night from 09.00 to 11.00 pm. The results showed that the mean temperature was 31.29°C during the day and 27.4°C at night. Spatially, the day time showed that the high temperatures (32 to 35°C) are generally located in the downtown areas which are crowded with buildings such as residential, offices and shops. Meanwhile, a lower temperature (29 to 31°C) is generally located in countrysides or outside the city in the form of green areas and open land. The results show that a fairly high temperature causes the comfort of the city the temperatures reduced. Therefore, handle UHI phenomenon needs to be done in an integrated and sustainable.
