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.

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.

Abstract

The Geosite Area of Gorontalo Evaluated Using Quantitative Descriptive Research Method for Tourism Preparedness Post-COVID-19" The Gorontalo geosite area was evaluated using a quantitative descriptive research method in this study to determine its readiness to host tourism after COVID-19. Changes in the attitudes and behaviours of tourists have occurred as a result of the COVID-19 epidemic, significantly impacting the domestic and international tourism environment. The objective of this research is to gain an understanding of the factors motivating tourists, classify various forms of tourism, and observe specific geosites in Gorontalo based on official designations. Different local attitudes towards the "new normal tourism" are crucial factors in the highlighted destination preparation differences presented in the conclusions. Despite the economic considerations influencing the continuous implementation of health protocols, the government, local communities, and businesses must collaborate towards achieving optimal and sustainable tourism recovery

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.
