Urban heat island phenomenon in majalengka regency

Abstract

The Majalengka Regency considering by The Government of West Java Province is one of the priorities of infrastructure development to sustain the accelerate of development. The conversion function of agricultural land into non-agricultural or industrial will affect land surface temperature, which triggers the urban heat island phenomenon. The purpose of this study was to analyze the spatial and temporal distribution of urban heat island and the assosiation of land cover, building density, and vegetation greenness with land surface temperatures in Majalengka in 2013, 2016, and 2019. Variables used in this study were land cover, vegetation greenness, building density, and land surface temperature obtained from the processing of Landsat Image 8 are validating survey at 98 points selected by random sampling method. The results showed that the phenomenon of urban heat island dominates the north to the Majalengka Regency. The Areas with low land surface temperatures are found in areas with land cover in the form of built land, low greenness, and high building density. The southern of Majalengka Regency of the land surface temperature is getting lower with vegetation land cover, high vegetation greenness, and low building density. Low land surface temperature is associated with high vegetation greenness and low building density while the highest surface temperature is associated with built-up area with high building density. The difference in temperature between 2013-2019 is around 6°C with a reduction in vegetation area around 109 km2.
