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

West Kaidundu is a village with diverse terrain conditions, covering high hilly areas, some lowlands, and coastal areas in Bulawa Sub-District, Bone Bolango Regency. The diverse morphological and geological conditions have an impact on the potential of natural resources, the distribution of limestone, and different geological structures.Research on the porosity of limestone is crucial to obtain information about its porosity value. A study analyzing the porosity of limestone in Kaidundu Barat Village has not been conducted before. Therefore, this research is significant and interesting to carry out at the study location. The results of the study reveal the geological conditions of the research area, which consists of three geomorphological units: pyroclastic ridge, karst plain, and alluvial plain units. The study area is composed of wackestone and mudstone limestone, pyroclastic breccia, and alluvial deposits. From the porosity analysis, the wackestone limestone in the study area, categorized as reservoir rock, falls into the poor category, while the mudstone limestone is classified as fair.

Abstract

This study examines the potential of limestone in Kayubulan Village, Batudaa Pantai District, Gorontalo Regency, to determine its suitability as a groundwater reservoir. The research focuses on understanding the relationship between rock density and porosity, which are key factors in water storage capacity. The methods employed include geological field mapping, specific gravity testing following SNI 1969:2008 standards, and petrographic analysis. Geological field mapping identified the distribution and characteristics of limestone facies, while specific gravity testing involved measuring dry weight (𝑊₀) and saturated weight (W_w),which were incorporated into Giancoli's (2014) density formula. Petrographic analysis was conducted to examine the inverse relationship between density and porosity in various limestone facies and to identify porosity types.Five samples representing Wackestone, Packstone, Crystalline Carbonate, and Coralline Framestone facies were analyzed for density, porosity, and water absorption. Based on Koesoemadinata's (1980) classification, porosity values were as follows: Wackestone 4.49% (negligible), Packstone 8.4% (poor), Wackestone FAK 12 10.54% (fair), Crystalline Carbonate 12.69% (good), and Coralline Framestone 23.7% (very good). Variations in micrite and sparite composition also influenced porosity; Wackestone FAK 15 showed lower porosity than FAK 12 due to its higher sparite content.Coralline Framestone emerged as the most viable reservoir candidate, as high-porosity, low-density rocks generally exhibit superior water absorption capacities. These findings highlight the significance of porosity and density in groundwater management and offer valuable insights for optimizing Gorontalo's water resources.

Abstract

The purpose of this research is to examine and interpret the geological setting of the Dulamayo Selatan area in Telaga District, Gorontalo Regency. The research addresses aspects of geomorphology, stratigraphy, and structural geology to develop a thorough understanding of the geological framework of the region. The methodology includes field surveys such as surface geological mapping, outcrop observations, and laboratory analysis for petrology and petrography. The findings indicate that the study area can be classified into two distinct geomorphological units: Lava Flow Ridge and Intrusive Hills. The stratigraphy comprises two rock units: the andesite unit, consisting of andesite and altered andesite, and the granodiorite unit. Structurally, the area is dominated by tension joints with a primary northeast-southwest orientation. It is expected that the findings of this study will contribute to a better understanding of the geological conditions of the region and assist in efforts related to natural resource utilization and the mitigation of geological risks in Dulamayo Selatan.
