Abstract

Rare earth elements (REEs) are a group of seventeen metallic elements consisting of scandium (Sc), yttrium (Y), and fifteen other lanthanide elements. Rare earth metals have an important role in various technologies, so the analysis and separation of these elements from their minerals is very important to do. This study aims to characterize the tailings through X-Ray Diffraction (XRD), X-Ray Fluorescence (XRF), and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) techniques. The results of XRD analysis show that the mineral composition of tailings is dominated by quartz (SiO₂) with a percentage of 88%, followed by albite (NaAlSi3O8) with a percentage of 11%.  In addition, the results of XRF analysis show that the main elemental composition in the tailings consists of SiO₂ (69.294%), Al₂O₃ (20.20%), and Fe₂O₃ (4.681%). In addition, heavy metal concentrations in the tailings indicate a potentially serious risk of environmental pollution, with arsenic (As) reaching 100 ppm and mercury (Hg) more than 5 ppm. In addition, rare earth elements identified in the tailings include cerium (Ce) at 14,578 ppm, lanthanum (La) at 7,850 ppm, and neodymium (Nd) at 6,897 ppm. This method is expected to help tailings management, reduce environmental impacts, and support sustainable mineral utilization.

Abstract

This study was conducted in Block “X” of the Pani Gold Project Area, Buntulia District, Pohuwato Regency, Gorontalo Province, with the aim of examining the regional geological conditions, including geomorphology, stratigraphy, and geological structures. The methods applied consist of geological field mapping supported by petrographic analysis. The results indicate that the study area is divided into two main geomorphological units, namely a volcanic hill unit that dominates the area with undulating to steep morphology, and an alluvial plain unit developed along river systems. The stratigraphy of the study area comprises four lithological units, including granodiorite, diorite porphyry, dacite porphyry of Pliocene age, and alluvial deposits of Holocene age. The geological structures identified include fracture systems and normal faults with a sinistral (left-lateral) component trending northeast–southwest, as well as the presence of fault gouge and fault breccia indicating relatively intense deformation. Overall, the geological characteristics of the study area reflect a strong relationship between lithology, geomorphology, and structural controls in shaping the landscape development.

Abstract

The East Arm of Sulawesi is an active tectonic zone formed by the collision between the Banggai-Sula microcontinent fragments and the East Sulawesi Ophiolite Complex. This research was conducted in Lamo Village and its surrounding areas, Pagimana District, Banggai Regency, to identify detailed geomorphological, lithostratigraphic, and structural geology characteristics, which currently remain limited. The research methods include field mapping, morphometric analysis using DEMNAS data and structural kinematic analysis using stereographic projection. The results indicate that the geomorphology of the study area is divided into two units: the Structural Hills Unit (slope 2–50%) and the Coastal Plain Unit (slope 0–2%). Lithostratigraphically, the study area consists of a Peridotite Unit covering 23.81 km² and an Alluvial Unit covering 1.83 km². Structural analysis of the Peridotite Unit reveals a high intensity of extension joints with a maximum principal stress (σ1) oriented at 127°/71° (NW–SE).

Abstract

This community service activity aims to increase students' understanding of the environmental impacts of mining activities and foster an environmentally conscious character among students at SMA Negeri 2 North Gorontalo. The background to this activity is based on the increasing number of environmental problems caused by mining activities, such as water pollution, land degradation, declining air quality, and ecosystem degradation. Therefore, educational efforts are needed to raise awareness among the younger generation about the importance of environmental conservation. The method used in this activity is participatory outreach and education through material delivery, interactive discussions, questions and answers, and motivation related to environmentally friendly behavior. The target group for this activity was 30 students at SMA Negeri 2 North Gorontalo. Evaluation of the activity was conducted through observation, documentation, and the distribution of questionnaires to measure the level of understanding of participants after participating in the activity. The results showed that students responded very positively and demonstrated a high level of participation throughout the program. Based on the questionnaire results, 80% of students were in the high understanding category, 13.33% in the medium category, and 6.67% in the low category. These findings indicate that the educational activity successfully increased students' knowledge of environmental issues in mining while fostering environmental awareness and character. Thus, environmental education based on mining issues can be an effective strategy for developing environmental literacy, ecological awareness, and environmental responsibility in the younger generation as part of efforts to achieve sustainable development.

Abstract

Landslide susceptibility assessment is essential for supporting geological hazard mitigation in hilly urban areas where slope morphology, lithological conditions, structural discontinuities, rainfall, and land-use dynamics interact. Hulonthalangi District, Gorontalo City, is characterized by steep hillslopes, variable lithology, structural lineaments, and settlement development along slope areas. This study aims to delineate landslide susceptibility zones using an integrated Geographic Information System and Analytical Hierarchy Process approach. Eleven conditioning factors were considered, including slope, rainfall, geology, distance from lineament, distance from stream, soil type, topographic wetness index, aspect, curvature, distance from road, and land use/land cover. The AHP weighting indicates that slope, rainfall, geology, and distance from lineament are the dominant factors controlling slope instability. The resulting landslide susceptibility map consists of five classes: very low, low, moderate, high, and very high. The high susceptibility class occupies 4.636413 km² or 45.44% of the study area, while the very high class covers 0.711134 km² or 6.97%. These zones are mainly associated with steep hillslopes, weathered and fractured lithology, proximity to structural lineaments, and areas affected by surface-water concentration. The generated susceptibility map provides a scientific basis for land-use control, slope management, infrastructure planning, and landslide mitigation in Hulonthalangi District.

Abstract

This study was conducted in Taludaa Village with the objective of analyzing geological conditions, including geomorphology, lithology, and geological structures, as well as assessing the geodiversity potential of the waterfall geosites using Brilha’s (2015) classification. The methodology involved surface geological surveys, laboratory analysis, and studio processing. Results show that the geomorphology of the study area comprises two units: structural hills and an alluvial plain. The stratigraphy consists of andesite, granodiorite, and alluvial deposits. Geological structures identified include tension joints caused by compression stress and an oblique fault trending southeast–northwest. At Station ID43, a normal right-slip fault with a dip angle of less than 45° was observed. The geological history indicates tectonic activity from the Early to Middle Miocene, forming andesitic volcanic rocks of the Bilungala Formation, followed by Middle to Late Miocene granodiorite intrusion, and Holocene alluvial deposition continuing to the present. The geodiversity inventory identified two waterfall sites (Geosite 1 and Geosite 2). Both geosites demonstrate high scientific and educational value, moderate tourism value with a total score of 245, and very low vulnerability with a total score of 100. These findings highlight the significant scientific and educational potential of the Taludaa waterfalls, supporting their role in geoconservation and sustainable geotourism development in Gorontalo.

Abstract

This study aims to determine the lithological characteristics, texture, and elemental composition of lateritic nickel deposits in Block X, Wolo District, Kolaka Regency, Southeast Sulawesi Province. The analysis focuses on Ni, Fe, MgO, and SiO₂ contents based on geochemical exploration data obtained from PT Ceria Nugraha Indotama. Data processing was carried out through composite data analysis, descriptive statistical analysis, and visualization using histograms, scatter plots, and ternary diagrams. The results show that the lateritic nickel deposit in the study area can be divided into three main zones: limonite layer, saprolite layer, and bedrock. The limonite layer is characterized by high Fe content (28.65–40.33%) and a clayey texture, while the saprolite layer exhibits higher concentrations of Ni (0.08–2.10%) and MgO (10.29–32.20%) with fine to coarse sandy texture. Intensive laterization processes under humid tropical conditions play a crucial role in the formation, differentiation, and enrichment of lateritic nickel deposits in this lokasi.

Abstract

The study area exhibits diverse geological conditions, one of which is reflected in its geomorphological characteristics that are important to investigate. Olele is located within the southern mountainous zone of Gorontalo and is characterized by hilly to steep terrain. This study aims to identify and classify landform units based on geomorphological analysis. The research method involved field-based geological surveys, including direct geomorphological observations, lithological identification, and geomorphological mapping supported by secondary data analysis. The results show that the study area consists of three geomorphological landform units, namely alluvial plains covering an area of 17.84 ha, reef terrace plains with an area of 17.43 ha, and fault zone hills occupying 1,072.23 ha. The morphography of the area ranges from lowlands to high hills with elevations between 0 and 960 meters above sea level. Slope gradients vary from flat to very steep. Morphogenetic analysis indicates that endogenous processes, particularly tectonic activity, play a significant role in shaping the landscape, as evidenced by the presence of joint structures. Lithologically, the area is composed of unconsolidated alluvial deposits, reef limestone, and volcanic rocks that have undergone weathering and erosion. These findings demonstrate that the geomorphology of the Olele area is strongly controlled by tectonic processes, lithological variation, and surface processes, which together contribute to the development of distinct landform units.
