Abstract

A continuously growing population day by day means that the need for water is also increasing.The majority of the Botumoputi Village community uses groundwater every day through dug wells and drilled wells for their daily needs. The purpose of the study was to determine the subsurface geological conditions that can be used as a reference in estimating the location, thickness, depth and type of aquifer. The method used is the resistivity geoelectric method using the Schlumberger configuration. Measurements were carried out at 3 points with a span length of 300 m each. Data processing and interpretation using software IPI2win. The results of processing Schlumberger configuration geoelectric data and subsurface geological interpretation to identify the type of groundwater aquifer in the Botumoputi area show 3 layers of rock types based on their resistivity values, namely top soil, clay and sand. It is estimated that the potential for groundwater is found in TS1 and TS2 where the lithology that acts as an aquifer is sandstone with a resistivity value of 16.8 - 42.7 ohms with a depth ranging from 3.93 - 17.2 m with a thickness of 8.88 - 13.27 m and is interpreted as a shallow aquifer.

Abstract

This research was conducted in the Mananggu area and its surroundings, Mananggu District, Boalemo Regency, Gorontalo Province. The study aims to map the geological conditions and identify the characteristics of geomorphology and geological structures developed in the area. The methods employed included surface geological mapping for field data collection, followed by laboratory analyses. Geomorphologically, the research area is divided into two units: the Volcanic Hills Unit and the Structural Hills Unit. The stratigraphy consists of the Eocene-Oligocene Porphyritic Andesite Unit (Tinombo Formation) and the Pliocene Granite Unit (Bumbulan Granodiorite Formation) acting as an intrusive body. The geological structures are controlled by a transtensional regime resulting from compression, manifested as NW-SE shear joints, right normal slip faults, and normal right slip faults. The landscape evolution is strongly influenced by the interplay between the resistance of the igneous lithologies and the active tectonic deformation that shapes the drainage patterns and slope configurations.

Abstract

This study summarizes various studies on the use of remote sensing technology, both multispectral and radar, in the fields of geology, hydrology, and the environment. The main journals reviewed show that satellite imagery such as Landsat TM, Landsat 8 OLI/TIRS, Sentinel-2, ASTER, and LiDAR radar data play a significant role in identifying the physical characteristics of the earth, such as soil moisture, mineralization, lithology, suspended sediments, and surface deformation due to tectonic activity. The use of multispectral imagery is effective in mapping lithology and minerals, while radar and LiDAR remote sensing excel in morphological analysis, geological structure, and hydrodynamic modelling of flood inundation. Overall, remote sensing has proven to be an efficient, time-saving, and accurate tool in supporting geological resource exploration, topographic mapping, and natural disaster mitigation. The integration of various image data sources increases the validity of interpretation results and can be an important basis for decision-making related to spatial planning, mineral exploration, and environmental management in Indonesia.

Abstract

This study aims to analyze the geochemical characteristics of andesite rocks within the Tinombo Formation located in Biluhu Barat Village, Biluhu District, Gorontalo Regency. Data collection was conducted through geological mapping and geochemical analysis using X-Ray Fluorescence (XRF) to determine the magma series, magma type, and tectonic setting of the rock origin. The results show that the study area consists of porphyritic andesite and granodiorite units. Geochemical data indicate that the andesite rocks belong to the calc-alkaline magma series, with rock types identified as andesite and basaltic andesite. Geochemical diagrams reveal that the rocks originated from an Island Arc Calc-Alkaline Basalt tectonic setting. The calculated magma source depth ranges from 156 to 164 km, indicating magmatic processes occurring within a subduction zone. This study contributes to a better understanding of the tectonic framework and magmatic evolution in the Gorontalo region.
