Analysis of thermal comfort of settlements based on urban humidity index in Yogyakarta City

Abstract

Increasing urban development has led to an increase in land use, particularly in settlements. The massive and uncontrolled growth of settlements can lead to a decrease in the quality and thermal comfort of the settlements. Yogyakarta is one of the cities in Indonesia with rapid development and population growth. This study aims to analyse the quality and thermal comfort of settlements in Yogyakarta city. The remote sensing data used is Landsat 8 OLI image for the analysis of vegetation index, land surface temperature, and urban heat island (UHI). The results of the model are presented in the form of maps so that the spatial pattern of UHI can be identified and correlated with the comfort level calculated using the temperature humidity index (THI). Based on the results of the data analysis conducted, it is known that the analysis of thermal comfort in the city of Yogyakarta is dominated by the comfortable class (97%), uncomfortable class (3%), and very uncomfortable class (0%).
