Groundwater recharge in the Jakarta Groundwater Basin was estimated using water budget and water table fluctuation methods. The study found that groundwater recharge ranged from 209 to 885 mm/year, with the highest recharge in Bogor and the lowest in Kemayoran. Only 8-15% of annual rainfall is converted into groundwater recharge in the study area. The water table fluctuation method estimated groundwater recharge at 240 mm/year. Factors like geology, land use, and climate variations influence the recharge amount. Effective groundwater management is crucial for sustainable development and conservation in the Jakarta groundwater basin.
