Spatial Multi-Criteria Analysis for Urban Sustainable Built Up Area Based on Urban Heat Island in Serang City

Abstract

The rapid of human occupancy in Serang City has caused the development activity of the built-up area increased significantly. Increased development has led to the phenomenon of Urban Heat Island (UHI), namely the increase in air temperatures in the Serang City that threatens the survival of society. Meanwhile, at the same time, Serang City is urged to keep doing development to provide land for community activities. Against this background, spatial analysis is needed to determine the development of built-up area based on the principle of sustainability. Regional modeling of sustainable area development based on sustainability in Serang city can do by using SMCE (Spatial Multi-Criteria Evaluation). The various criteria covering UHI distribution, distance from the road, distance from the river, land use data, and physiographic data were processed by specific weighting so that the resulting suitability area of the built-up area. The distribution of UHI in Serang City agglomerated in the center of Serang City with the highest surface temperature value of 32C. Meanwhile, through the SMCE modeling results, the region's suitability area of 3.313 Ha was established which distributed at several points in Serang City and spread linearly following the road network with the extended area of 3.538 Ha. Meanwhile, the central, north, and west of Serang City area dominated by unsuitable for a built-up area with a total area of 19.553 Ha.
