Abstract

Dambalo is a village located in Tomilito sub-district, North Gorontalo Regency, Gorontalo Province. This study aims to identify and describe the geological characteristics of the Dambalo area and its surroundings. The study focuses on geomorphology, stratigraphy, geological structure, and geological potential. The methods used include field observation and laboratory analysis. Field observations include geological mapping, rock sampling, and measuring geological structures using a geological compass. Meanwhile, laboratory analysis was carried out to determine the mineral composition, rock texture and rock name through petrography and stratigraphic analysis. The results of the study indicate that the study area is stratigraphically composed of the oldest to the youngest lithological units, namely porphyry andesite units, volcanic breccias, and alluvial deposits. The dominant geological structure is tensile fractures (tension fractures) with three main orientations. The geological potential in this area includes C-type mining materials, which mainly consist of porphyry andesite rocks, which have economic value for the construction industry. However, this area also has the potential for landslide hazards, namely in areas with steep slopes. This research is expected to contribute to the management of natural resources and mitigation of geological landslide disasters in Dambalo and its surroundings.

Abstract

Reservoir rocks are subsurface rocks that are porous and able to store and flow groundwater that can be utilized by the surrounding community. The rocks that function as groundwater reservoirs in the Bintalahe area are limestone. Almost the entire research area is composed of limestone so it is interesting to study. Gorontalo is located on the northern arm of Sulawesi which is bordered by two provinces and two seas, namely North Sulawesi Province in the east, Central Sulawesi Province in the west, Tomini Bay in the south and the Sulawesi Sea in the north. Gorontalo has interesting geological diversity to study, especially in Bintalahe Village. This study aims to analyze the porosity value of each limestone facies in the research area. The methods used are field observation and laboratory analysis as well as analysis of the specific gravity of coarse aggregate. The results of the study consist of three limestone facies, namely mudstone facies, batupakes facies and pumice facies. The potential of limestone in the Bintalahe area as a groundwater reservoir is in the category of poor to quite good.

Abstract

The Trans Sulawesi Road in Olohuta Village, Kabila Bone District, is a crucial route connecting Gorontalo and North Sulawesi. Given the steep roadside slopes, geological analysis and slope stability assessments are essential to prevent landslides that could disrupt access. This study evaluates geological conditions and slope stability using the Rock Mass Rating (RMR), Slope Mass Rating (SMR), and Safety Factor (FK) methods. Geological mapping reveals dacite rock formations within a fault zone, with a Northeast-Southwest structural orientation. RMR analysis classifies slope 1 (RMR = 62) and slope 2 (RMR = 57) as "good." SMR analysis indicates partial stability, with slope 1 experiencing Direct Toppling (20.47%) and slope 2 undergoing Flexural Toppling (18.52%), resulting in SMR values of 58.25 and 53.25, respectively. The Bishop Method shows low safety factors, with values of 0.59 for slope 1 and 0.56 for slope 2, indicating instability. To improve slope stability, this study recommends modifying slope geometry.

Abstract

The research location is situated in Mount Pani, Hulawa Village, Buntulia District, Pohuwato Regency, Gorontalo Province. The objective of this research is to determine the geology of the study area and analyze the hydrothermal alteration zones within the research area. The research methods used include surface geological surveys and petrography. The findings reveal that the geomorphological conditions of the research area are divided into one unit, namely a fault zone hill unit. The stratigraphy of the area consists of four units: tuff unit, porphyritic rhyodacite unit, banded rhyodacite unit, and rhyodacitic breccia unit (auto breccia). In terms of geological structures, there are joints in the form of shear joints, which are the result of compression stress, and tension joints. The fault structures in the study area include oblique faults, with the dominant directions being NE-SW and SE-NW. At station M044, a sinistral normal fault (normal left-slip fault) was found; at station M052, a dextral normal fault (normal right-slip fault); at station M079, a sinistral fault (left-slip fault); while fault breccia at stations M02, AL052, and AL29 is interpreted as a sinistral fault with a NE-SW direction.

Abstract

Palu City is one of the major cities on Sulawesi Island, experiencing rapid population and economic growth. However, the 2018 earthquake, tsunami, and liquefaction events caused infrastructure and environmental damage, affecting water resources in the area. Therefore, this study aims to determine the pH, temperature, DHL, TDS, and iron and manganese content of groundwater. The study was conducted by directly measuring the physical and chemical properties of groundwater in 25 water sources, including springs, dug wells, and drilled wells. In addition, groundwater and aquifer material samples were taken for laboratory testing using AAS and XRD. The results of the study showed that the groundwater pH ranged from 7.0 - 8.3, temperature 27.4 oC to 36.1oC, TDS ranged from 170mg/L – 4,733 mg/L, DHL ranged from 341µS/Cm – 9,513µS/Cm, iron content 0.1 – 0.26 mg/L and manganese content 0.16 mg/L – 0.38 mg/L. The source of iron and manganese is indicated to come from the aquifer as shown by the XRD results containing Hematite, Magnetite and Pyrolusite minerals not from anthropogenic activities.

Abstract

Reservoir rocks are characterized by their ability to allow water to infiltrate beneath the surface, enabling them to store and transmit fluids due to their permeability. Porosity refers to the presence of pores or void spaces within rocks, which determines their capacity to store fluids. Therefore, the porosity of a rock plays a significant role in the volume of liquid or gas it can contain. The study area is located within the Ql Formation, and no prior research has been conducted on limestone reservoir rocks in Buhudaa Village, Batudaa Pantai Subdistrict, Gorontalo Regency. The research covers an area of approximately 3.3 km², including the villages of Buhudaa, Bongo, and Lopo. This study aims to map the geological conditions of the Buhudaa area and analyze the lithological characteristics and quality of limestone as a groundwater reservoir. The methods employed include petrographic analysis and specific gravity testing. The results indicate that the geomorphological conditions of the area consist of structural and low-structural hills. The limestone was classified into three lithofacies: Mudstone, Wackestone, and Packstone. Geological structures were identified using linear lineament analysis, which distinguished ridges and valleys. The dominant orientation of these features trends northeast–southwest. Based on Koesoemadinata’s (1980) classification, the quality of limestone as a reservoir rock in the study area ranges from fair to very good.

Abstract

One of the natural resources commonly utilized as raw material in industries—particularly for piling foundations, construction base mixtures, and other basic building materials—is igneous rock. The quality of the rock used as a construction material plays a crucial role in determining its suitability for various infrastructure applications. Therefore, specific physical and mechanical properties of the rock must be evaluated to assess its feasibility for construction use (Yuwanto and Araujo, 2020). This study aims to analyze the characteristics and quality of the rock at the research site and assess its suitability based on the classification from the Indonesian Industrial Standard (SII) 0378-80. The methods used include the Geological Strength Index (GSI) and Unconfined Compressive Strength (UCS). Data were obtained from field observations using the scan line method and laboratory testing of rock mechanical properties. The GSI analysis shows that the rocks have Structure Condition Rating (SCR) values of 6, 10, and 7, indicating structural influence ranging from blocky/disturbed to disintegrated conditions. The UCS analysis results show compressive strength values ranging from 233.351 kg/cm² to 1.161 kg/cm². According to the SII 0378-80 classification, these values reflect the varying levels of suitability of the rock for construction purposes.
