The Effect of Green Vegetation Density in increasing Thermal Comfort in Urban Environments Through Preventing Increases in Environmental Temperature: A Study in Yogyakarta, Indonesia, at Kapanewon Depok, Sleman

Abstract

Green vegetation has many benefits in balancing nature. This research aims to see the relationship pattern between Green Vegetation Density (NDVI) and Urban Heat, and to see the Effect of Green Vegetation on Human Thermal Comfort. The research was carried out in 3 sub-districts in Depok, Sleman, Yogyakarta making use of Landsat-8 satellite imagery and the remote sensing technology which is equipped with measurements of microclimate elements in the field for calculating Thermal Comfort and also completed with Correlation-Regression analysis. Based on the results, a pattern was obtained that locations that have a high level of Vegetation Density will have a low Urban Temperature, whereas locations that have a low level of Vegetation Density or non-Vegetation will have High urban temperatures, and it was found that all correlations were positive with the highest order being the Caturtunggal Zone with an r value of 0.7 with a correlation level of 0.4901 (49.01%), then in second place namely the Condongcatur Zone, namely with The r value is 0.6998 with a correlation level of 0.4897 (48.97%) and the last is the Maguwoharjo Zone, namely with an r value of 0.1555 with a correlation level of 0.0242 (2.42%). It is concluded that Green Vegetation is anti-urban heat and protects Thermal Comfort. NDVI prevents Temperature increase
