【 摘 要 】

The increasing of population growth in the Coastal Area of Pekalongan City has caused serious problem to the domestic water supply. It was getting worst due to seawater intrusion phenomenon. This research aims to investigate seawater intrusion using geophysical method and observe its impact to the domestic water fulfillment. Three sections of 2D resistivity were run approximately 250 meters'perpendicular from the coast line. The resistivity data were processed using RES2DINV software. We also did aninterview to 90 householdsto find out the impact of seawater intrusion in domestic water usage. The result showed that seawater has intruded up to 800 meters from the coast (represent with very low resistivity,
