Abstract

Urban Heat Island (UHI) is a global issue that affects many cities, including Jakarta, Indonesia. Because of its dense population, expanding infrastructure, and scarcity of green space, Jakarta as the capital and metropolitan center of Indonesia experienced severe effects from UHI. This city is rapidly becoming more urbanized, which has led to a decrease in vegetation and an increase in surface temperature. These changes have made heat-related issues worse and put the population's health at risk. Previous research shows that the intensity of UHI in Jakarta is among the highest in Southeast Asia, with temperatures in some areas reaching 4° C higher than the surrounding rural areas. Due to its critical function in temperature regulation through evapotranspiration and heat absorption, the reduced amount of green open space (GOS) in urban areas is a significant contributing element to urban heat island effect (UHI).
Urban green space is known to have a significant role in mitigating the effects of urban heat islands. In urban areas, a minimum GOS requirement of 30% of the total area is established by the Minister of Public Works and Public Housing Regulation No. 5/PRT/M/2008. Unfortunately, Jakarta lacks green space in lots of locations, particularly in heavily populated regions where it is typically distributed unevenly. The objective of this research is to determine the need of GOS location by analyzing the UHI distribution in Jakarta. To provide a thorough and data-based approach for prioritizing the development of green space in Jakarta, this study will combine spatial analysis with the Analytical Hierarchy Process (AHP) approach. The results of the analysis shown that the variable hierarchy that causes UHI is LULC, vegetation, population density, LST, air temperature, rainfall, and topography. In addition, the distribution of UHI in Jakarta is dominated by high class where city temperature is very hot. Three priority classes are generated following the use of Weighted Overlay Variables to analyze GOS priority sites. It shows that Jakarta has many priority places that need to be developed.
