URBAN HEAT HAZARD THREAT ON UNIVERSITY CAMPUS (University of Indonesia and University of Malaya)
Keywords:
Land cover, Urban heat hazard, Threat, Spatial analysisAbstract
Urban landcover reflects the sun heat called urban heat signature. The urban university campus,
as part of an urban environment, had a potential urban heat hazard. These urban heat hazards related to the
highest temperature when above the threshold will become a hazard. The research aims to assessments of urban
heat hazard thread on universities campus. The study area chose the University of Malaya (UM) and the
University of Indonesia (UI) Campuses, which tropical area. This research used spatial-temporal analysis
employing satellite images during the period 2013-2016, Field Measurement of Air Surface Temperature in
2015, and Perception Study of Heat Hazard 2017-2018. The study found an urban heat signature maximum is
33-36oC and a trend of UHS since 2013-2016 with temperature >32oC both UM and UI campuses. Urban heat
hazard overlaid from urban heat signatures, air surface temperature, and perception of heat on landcover types.
The study concludes that increased temperature above the threshold is causing by land cover change on tropical
university campuses. The temperature of Urban Heat Signature, Air Surface Temperature, and Perception
Study of Heat concludes that a combination of three aspects (overlaid) generated an Urban Heat Hazard on
tropical university campuses. Both UM and UI campuses had a distribution a very high of urban heat hazards
related to paved open space and building covered. The study concludes that urban heat hazard threat is causing
by temperature above a threshold based on landcover types on tropical university campuses.
