Understanding Spatial Planning Policies in Responding to Urban Heat Island Using GIS Analysis in The Kendal Industrial Area

Abstract

The formulation of spatial planning strategies in an area is strongly influenced by the development of issues and problems in the area. Spatial planning policies contained in a regional regulation must be able to be aware of and deal with all current and future problems. Urban Heat Island) is currently a very growing issue in various regions in Indonesia which is influenced by many factors, one of which is the increase in built-up land. The issue of the Urban Heat Island is important because its effects are starting to be felt, including natural degradation, health, economic losses to excessive energy use. One of the most dominant areas in contributing to hot temperatures in urban areas is the industrial area. Kendal Regency is one of the regions in Indonesia with a fairly dominant industrial estate development. Industrial areas that are synonymous with built-up land, air pollution and the lack of green open spaces are one of the triggers for an increase in temperature. In contrast to the negative effects caused, the development of industrial estates in Kendal Regency is one of the drivers of the regional economy so that its existence is considered important. This study aims to understand spatial planning policies in response to the Urban Heat Island in the Kendal Regency industrial area. The research method used is spatial analysis using Landsat 8 imagery with supervised classification to see the UHI phenomenon in the Kendal industrial area, the results of which are used as a basis for evaluating spatial policies in response to UHI. The spatial policy of Kendal Regency in the designation of industrial areas has not fully responded to the UHI phenomenon in industrial areas, although 13 of the 14 clauses indicate the potential for an increase in surface temperature. UHI in the Kendal Regency spatial policy has not been seen as a threat to urban areas. Mitigation efforts against UHI mentioned are only in the form of providing green open space and waste management. It is hoped that this research can be input in improving spatial planning policies in the Kendal Regency industrial area, especially to suppress the increase in temperature.
