Ecological function of green open space as water infiltration: study in kalijodo green open space, north jakarta

Abstract

Kalijodo Green Open Space is a green open space set by the DKI Jakarta Provincial Government in 2017. Related to the ecological function of green open space as water infiltration, a literature study was conducted to analyze the condition of Kalijodo green open space based on supporting data sources using descriptive analysis techniques. The results of the analysis show that the Kalijodo green open space has not been able to carry out ecological functions as well as water absorption. Based on the imagery in Google Earth, it is seen that Kalijodo s green open space is very minimal vegetation and looks barren. This condition has implications for hardening the soil, so that water is difficult to seep into the soil. In the last 5 years, the average rainfall intensity from October 2013 to March 2014 was 134.97 mmph and was a very high level of rainfall intensity. Green open space is included in flood-prone areas. With the condition of the Kalijodo green open space and the high intensity of rainfall, the ecological function of green open space as water infiltration has not been maximized.
