This conversion interferes with the regulations of air temperature and Thermal Humidity Index (THI). This research investigated the characteristics of green open spaces at Denggung Park and Gadjah Mada University Wisdom Park, examining their effects on microclimate conditions and the relationship between green space conditions and THI levels. The methods included a literature review, field measurements of vegetation and microclimate variables, tree crown profile analysis using Sexl-FS, and Spearman Rank Correlation. Results showed that tree density has a direct relationship with THI. The private green space (Wisdom Park), with 126.33 trees/ha, achieved superior THI compared to the public space (Denggung Park), with 49.01 trees/ha. The Gadjah Mada University Wisdom Park's more complex canopy structure and optimal canopy connectivity significantly enhanced THI. Spearman Rank Correlation analysis revealed strong relationships between the tree density and thermal comfort level for Denggung Park (-0.52) and for Gadjah Mada University Wisdom Park (-0.69), with a p-value &lt; 0.05. These findings confirm the critical importance of optimizing vegetation structure and density to support thermally comfortable urban environments.</p> Abi Abdillah Niko Ghaniyy Diah Fitri Astuti Ningrum Copyright (c) 2025 Diah Fitri Astuti Ningrum -, Abi Abdillah Niko Ghaniyy https://creativecommons.org/licenses/by-nc-sa/4.0 2025-09-15 2025-09-15 19 2 115 126 10.22146/jik.v19i2.16746
