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

The Bulango Ulu Dam is one of the strategic projects built in Tuloa Village, North Bulango District, Bone Bolango Regency, Gorontalo Province. In building a dam, geological analysis and slope stability are very important to avoid the risk of collapse or structural failure. This research aims to conduct geological analysis and slope stability at the Bulango Ulu Dam using kinematics methods. The kinematics method is used to determine the type of ground movement on the dam slope and identify the probability value of failure. Geological data related to lithology, petrography, geological structure and geomorphology are collected through direct observations and in the laboratory. Then, this data is used to determine geological conditions, geological structure and geomorphology which are then interpreted in relation to slope stability. The research results show that the geomorphological units are alluvial plains and low structural hills. The lithology that makes up the slopes of the Bulango Ulu Dam is composed of alluvial units and granodiorite units. The geological structure that develops is in the form of tensile joints in a general direction east-west (E-W) and cut by tension joints in a general direction north-south (N-S). The type and probability of ground movement that occurs based on segment, namely on segment A-B slopes in the form of Wedges (21.65%), segment B-C slopes in the form of Wedges (12.27%), segment E-F slopes in the form of Wedges (15.12%), and segment slopes G-H is a Wedge (21.8%). Based on the results of kinematic and boundary equilibrium analysis, the slopes on the Bulango Ulu dam are in the stable category. This research recommends that there is no need to make changes to the geometry of the dam slope because the slope is in a stable condition.

Abstract

The research is located in Gorontalo Province, precisely in Dumbo Raya District with coordinates 0°32’24” N and 123°4’32” E. Geologically, the research area is located on the North Arm of Sulawesi Island and belongs to the Southern Mountain Zone. The geological conditions of this region are influenced by complex tectonic activities and intensive geomorphological processes that form diverse landscapes. This research aims to determine the geological conditions including geomorphology, stratigraphy, and geological structures. The method used is field geological mapping supported by secondary data, through observations of rock outcrops, lithological descriptions, and measurements of geological structures. The results show that the geomorphology of the area is dominated by denudational hill units and alluvial plains. The hill units are composed of igneous rocks such as granodiorite and andesite that have experienced weathering and erosion, forming steep slopes. The alluvial plain units are composed of younger loose material. Stratigraphically, the research area consists of granodiorite, andesite, and limestone unit.

Abstract

The research area is located in South Suwawa District, Bone Bolango Regency, Gorontalo Province, which is part of the North Arm of Sulawesi characterized by complex tectonic conditions. This study aims to analyze the geomorphology and stratigraphy of the research area through geological mapping and lithological interpretation. The methods used include field surveys, rock sampling, petrology analysis and spatial data analysis. The results indicate that the research area consists of two geomorphological units, namely volcanic hills and floodplain units. Stratigraphically, the area is composed of four lithological units arranged from oldest to youngest: tuff, basalt, andesite, and alluvial deposits. The distribution of these units is strongly influenced by geomorphological conditions and fluvial processes.

Abstract

Sulawesi Island has high geological complexity due to the collision of three major plates, yet detailed petrographic studies in Gorontalo Province, particularly in West Biluhu Village, remain limited. This study aims to map the geological conditions (geomorphology, stratigraphy, structure) at a scale of 1:5,000 and to identify igneous rock types using petrographic methods. The methods include field surveys, slope and joint measurements, and thin section analysis under a polarized microscope. The results show that the geomorphology consists of Volcanic Hill Unit and Denudational Volcanic Hill Unit. The stratigraphy from oldest to youngest is Andesite Unit and Dacite Unit, correlated with the Tinombo Formation (Eocene–Oligocene). The geological structure is characterized by tension joints with northeast–southwest and north–south orientations. Petrography reveals hydrothermally altered andesite (quartz-filled microfractures, embayed crystal) and dacite with interstitial quartz. This study is important as an integrated geological baseline data and an initial indication of mineralization potential in the area.

Abstract

Tontayuo Village, Batudaa Pantai District, Gorontalo Regency is an area with hilly topography and morphological characteristics with variations in slope gradients as well as lithology and rainfall conditions that have the potential to trigger landslides. This study aims to analyze the lithology of study area and the level of landslide vulnerability in the area. The research methods include field geogogical mapping, secondary data processing, and spatial analysis based on Geographic Information System (GIS). Assessment of landslide vulnerability levels is based on slope gradient parameters, lithology types, rainfall, lineament density, and land cover. The results of the study show that the lithology that makes up the study area includes basalt, granodiorite, limestone, and alluvial units. Based ono the analysis results, the level of landslide vulnerability in the study area can be categorized into 3 (three) classes, namely, low landslide vulnerability class (29,93 ha), medium landslide vulnerability class (178,3 ha), and high landslide vulnerability class (197,38 ha).
