The green open space functions as a water catchment area and a source of thermal comfort

Abstract

Abstract The Kalijodo green open space has an area with a 48 % vegetation area. The ideal green open space has a vegetated area of 80 to 90%. This can affect its function as a water catchment area and a source of thermal comfort. This research examines the water absorption capability and the value of the thermal humidity index in the Kalijodo green open space. The method used in this research is descriptive analysis. Based on the research results, the water absorption capability that is owned is 54,56 %. The optimum value of water absorption capability is about 75 to 95 %. The value of the thermal humidity index obtained was 30,75, and it was in a very uncomfortable category. The comfortable category of thermal humidity index is less than 29. The Kalijodo green open space does not properly function as a water catchment area and thermal comfort source. Therefore, it is necessary to improve the Kalijodo green open space condition, especially in terms of vegetation conditions.
