AVAILABILITY AND NEED FOR RTH VEGETATION IN POTENTIAL INDUSTRIAL AREA OF MALANG REGENCY: LANDSAT 8 IMAGE ANALYSIS USING NORMALIZED DIFFERENCE VEGETATION INDEX METHOD

Abstract

Physical development planning of an area requires land as the main media to support the implementation of activities in various sectors. The development of industrial estates is the focus of the Malang Regency government in optimizing industrial potential and accelerating industrial-based economic development. The development plan will have an impact on increasing the area of built-up space resulting in reduced green open space in the industrial area. One of the environmental management that can provide thermal comfort in industrial areas is the urban forest. This study aims to analyze and evaluate the availability and need for vegetation to provide thermal comfort in industrial areas by utilizing Landsat 8 satellite images, the method used is remote sensing with the NDVI algorithm, processed using the Google Earth Engine cloud-based platform with open source code. Through the interpretation of secondary data, that the potential industrial area of Malang Regency is spread in several districts such as Singosari District, Pakis District, Tajinan District, Pakisaji District, Bululawang District, Gondanglegi District, Turen District, and Kepanjen District. The results of processing Landsat 8 satellite images in 2023 show that NDVI in Malang Regency has an index value in the range of -0.197 to 0.689
