This study investigates the quality of shallow groundwater as an indicator of seawater intrusion in Yosorejo Village, Batang Regency, located on the northern coast of Java. This study evaluates physicochemical parameters for Total Dissolved Solids (TDS), Electrical Conductivity (EC), and pH, incorporating geological factors to investigate preliminary indicators of saline intrusion. Groundwater sampling and analysis took place in September-October 2023 using seven domestic wells distributed at various distances from the coastline (0-4 km) and topographic elevations (0-10 meters above sea level). GIS mapping of TDS and Electrical Conductivity revealed peaks for TDS with a maximum reading of 1400 ppm and Electrical Conductivity with a maximum reading of 1970 µS/cm, indicating that saline intrusion is well under way. It also confirmed increasing tendencies towards decreasing elevations nearshore. Groundwater pH varies between 7 to 8.4, within tolerable standards but slightly basic inland along hydrolysis and lithological reactions. Geologically, this site is primarily covered by very porous layers of alluvial deposit silt sand, representing aquifers amenable to saline waters. This work presents its originality by doing integrated spatial hydrogeological analyses to identify saline intrusion affected areas within 0-500 meters onshore. This work contributes to the development of environmental physics and hydrogeological research by confirming empirically for the imbalanced interface between seawater and groundwaters on tropical low-lying areas, pressing for alleviating strategies to secure groundwaters' sustainability.
