Abstract

The fulfillment of clean water needs in Sengkubang Village is done by utilizing groundwater, which in some locations still has a brackish to salty. This situation is one indication of seawater intrusion into groundwater because Sengkubang Village is a coastal area. This study aims to estimate the distribution of seawater intrusion based on the subsurface resistivity value. The method used is the resistivity method with dipole-dipole configuration. Measurements in the field apply six lines with a length of 55 m and the smallest electrode distance of 5 m. The distance of each line from the coastline is approximately 410 m, 485 m, 560 m, 635 m, 710 m, and 785 m. The interpretation results show that the seawater intrusion at the study area has a resistivity value of 0.223 Ωm - 5.03 Ωm at a depth of 0.854 m to 10.9 m. The subsurface layer at the study site is composed of sand, sandy clay, and gravel sand mixed with silt. The unconfined aquifer layer, which is interpreted as sand, is thought to have experienced seawater intrusion to 785 m from the coastline.

Abstract

Tulungagung and Trenggalek are two regencies located south of Java Island with quite complex geological conditions because they are located in the Southern Mountains area. This study aims to identify the presence of faults based on the magnetic anomaly value of the Tulungagung sheet. The presence of faults at the research site were determined based on three lines on the regional magnetic anomaly using First Horizontal Derivative (FHD) and Second Vertical Derivative (SVD) derivative analyses. The results show that the regional magnetic anomaly is -210.7 nT to 113.2 nT. Line A-A' identified two fault locations at a distance of 15 km and 27 km from the line's starting point. Line B-B' identified three fault locations at a distance of 4 km, 27 km, and 45 km from the line's starting point. Line C-C' identified three fault locations at 10 km, 22 km, and 42 km from the line's starting point. The interpretation results also obtained subsurface lithology in the Alluvium Formation, Arjosari-Mandalika Formation, Wungkal Limestone Formation, and Malihan Rock Formation.
