A Case Study of urban heat island based on Urban Growth and Thermal Impact in Sidoarjo East Java

Abstract

Sidoarjo is one of the districts in the Surabaya Metropolitan Area (SMAs). This has led Sidoarjo Regency to experience an increasing rate of urbanization and rapid development, especially in the industrial and residential sectors. With these anthropogenic activities, Sidoarjo Regency has experienced changes in land cover areas. Areas or regions that were originally green areas have gradually turned into built-up areas or land. The change in land cover area can make the surface temperature in Sidoarjo Regency increase, especially in the city centre area with a high rate of urbanization and development. This situation can eventually trigger the Urban Heat Island (UHI) phenomenon. This urban heat island phenomenon will be very detrimental to urban areas if not handled with the right strategy, because it will damage the environment and ecosystems and can be the largest contributor to the increase in global surface temperatures. The aim of this study is to calculate the growth of the heat island phenomenon in Sidoarjo district.
