Abstract


Climate change is an issue of global concern, one of which is Urban Heat Island (UHI). The phenomenon of Urban Heat Island is the main problem in every developing city in the world against global warming. Urban Heat Island or Hot island is a phenomenon where the air temperature of the building's dense city is higher than the surrounding open air temperatures both in the village and in the suburbs. This problem is also supported by the high urbanisation process in a city that seemed to never stop. The purpose of this research is to determine the change in the value of UHI (Urban Heat Island) values in central Jakarta city in 2013 and 2018. The method used is Split Window Alghoritm (SWA). Split Window Algorithm uses band 10 and band 11 on Thermal Infrared Sensor (TIR), Band 4 and band 5 on Optical Land Imager (OLI). Results of changes in the spread of LST in central Jakarta City 2013 the dominant temperature value 32-38°C While in 2018 the
dominant temperature at 38-44°C is also available in some areas of temperature 44-51°c and the result of changes in the spread of UHI year 2013 to 2018 increased 90% in which in the year 2013 is still dominated by the temperature value -8-8°C (low to moderate) while for the year 2018 look low classification significantly decreased and the temperature value -4-0°C spread almost all over the region, for a temperature value of 0-5°C (high) impacted UHI Increased almost scattered throughout the study area and most affected is in Kemayoran district.
