Analysis of Urban Heat Island Phenomenon as A Global Warming Control Based on Remote Sensing in Jember Urban, Indonesia

Global warming is a world problem because it has a significant impact on the survival of the earth, which is the Urban Heat Island (UHI) phenomenon. Jember Regency is a district with a relatively high population growth rate. Total population growth per year is 0.55% in 2020. In general, increasing t...

Description
Summary:Global warming is a world problem because it has a significant impact on the survival of the earth, which is the Urban Heat Island (UHI) phenomenon. Jember Regency is a district with a relatively high population growth rate. Total population growth per year is 0.55% in 2020. In general, increasing the urban population increases the need for built-up land to support human activities and can affect surface temperatures, producing the urban heat island phenomenon. This study analyses the UHI phenomenon in 3 sub-districts in urban Jember using the Landsat 8 OLI remote sensing image processing method and TIRS Multispectral Imagery to obtain surface temperature values and high-resolution aerial photos from 2013 to 2021, which will be used to identify surface temperatures through several methods. Extraction is the use of supervised classification (supervised), NDVI (Normalized Difference Vegetation Index), and LST (Land Surface Temperature). The study results illustrate that the UHI value in 2013-2021 tends to fluctuate with decreasing temperatures. The Non-UHI classification dominates the urban area of Jember, where the majority are in the suburbs. Meanwhile, the highest UHI class value spreads in the downtown area.
