Batang Integrated Industrial Park (BIIP), Central Java, Indonesia, needs the support of water sources, one of which is groundwater. In addition, industrial waste also can contaminate the groundwater. Therefore, assessing groundwater potential and quality is vital for an environmental baseline to manage sustainable groundwater resources. This research aims to identify the subsurface geology, especially the aquifer system and physicochemicals of groundwater, unprecedented in BIIP. The aquifer system determined the research method through geological surface mapping and geoelectrical surveys. Physicochemical properties, including temperature, pH, total dissolved solids (TDS), and electrical conductivity (EC), were directly measured in wells and springs in the industrial areas. The result shows that the BIIP is dominated by sand, silt, and clay, with sand as the primary aquifer located in-depth 1.35 to 47 meters, concentrated mainly in the western region and towards the east, decreasing as an unconfined aquifer. Groundwater flows from the south toward the Java Sea in the north. Groundwater has a temperature of around 27.3–30.9°C, pH 5.26–7.47, TDS 49–568 mg/L, and EC 100 – 613 μs/cm. It indicates that the quality and quantity of groundwater in the BIIP are quite suitable for use as raw water.

“…Bahan yang berada di bawah permukaan bumi saat dialiri listrik akan memiliki perbedaan resistivitas yang khas [8]. Metode geolistrik mampu mengukur perbedaan resistivitas lapisan batuan, lapisan air tanah konduktor memiliki resistansi tipe rendah, sedangkan lapisan batuan memiliki resistansi tipe tinggi dan kadar air rendah [9]. Metode resistivitas dibagi menjadi dua jenis resistivitas, yaitu metode pemetaan resistivitas dan metode resistivitas terdengar.…”

Penelitian ini dilakukan bertujuan untuk mengetahui struktur lapisan di bawah permukaan serta mengetahui potensi akuifer menggunakan metode Vertical Electrical Sounding (VES) dengan konfigurasi Schlumberger. Hasil penelitian diidentifikasikan bahwa penelitian yang dilakukan pada lokasi yang terpisah, yaitu lintasan 1 dan 2. Lintasan 1 diidentifikasi memiliki 4 struktur lapisan, diduga lapisan akuifer pada kedalaman 39,1 dengan litologi pasir dan kerikil. Lintasan 2 diidentifikasi memiliki 6 struktur lapisan, diduga lapisan akuifer pada kedalaman 14,1 dengan litologi pasir dan kerikil. Hasil penelitian yang didapatkan diduga bahwa lapisan akuifer pada lintasan 1 dan 2 termasuk akuifer dangkal, dimana pada akuifer dangkal biasanya ditemui adalah akuifer bebas yang menampung hujan dan berpotensi terkontaminasi zat lain. Peneliti menduga bahwa akuifer pada hasil penelitian termasuk akuifer tertekan dikarenakan pada lapisan akuifer ditutupi lapisan lempung yang bertindak sebagai lapisan kedap air dan lapisan akuifer pada penelitian ini berpotensi terhindar dari kontaminasi zat lain yang bagus sebagai potensi sumber daya air.

Landslides are the process of decreasing soil volume due to water deposits stored in the gaps in the soil due to the prolonged dry season. When the rainy season arrives, water will fill the gaps, causing the soil texture to soften briefly, causing landslides to occur. This research was conducted to determine the layers of slip planes in the Batutongkon tourist area, Battang sub-district as preliminary information on the volume and direction of material movement of landslide material by collecting data on 2 trajectories using the Wenner - Schlumberger configuration geoelectric method. Field data acquisition was analyzed using Microsoft Excel software to obtain apparent resistivity values. The principle of the resistivity method is to flow electric current into the earth through the contact of two current electrodes. Then the resulting potential distribution was measured and then processed using Res2Dinv software which produces 2D subsurface modeling, for 3D results using Microsoft Excel software as a medium for processing field data and continued using the surfer application to produce 3D modeling.
