Abstract

Jakarta is the capital city and also the largest metropolitan city in Indonesia that requires large amounts of residential land and clean water. The rapid development of infrastructure and the fulfillment of the need for clean water that is mostly supplied from groundwater can disrupt the subsurface balance which can cause disasters, one of that is seawater intrusion. The saltiness of groundwater in Jakarta is an old issue but still a debate among researchers about how the saltiness is happened. There are at least two different conclusions, namely caused by seawater intrusion or the presence of ancient seawater. This study aimed to determine the source of salt water in Jakarta, precisely in Penjaringan sub-district, North Jakarta based on gravity data. The results showed that groundwater conductivity was caused by the presence of salt in groundwater with a distribution pattern of high values in the north of the study area and further south, the values of conductivity, salinity and gravity decreased. The distribution pattern of residual gravity anomaly values and salinity values indicated that the salt water came from the North or the sea.
