Abstract

Abstrak Mohamad Alfarezy Mokodompit, 2026. Analisis Spasial Perubahan Pola Aliran Air Permukaan di Kawasan Pertambangan Emas PT J Resources Bolaang Mongondow. Program Studi Pendidikan Geografi, Jurusan Ilmu Bumi dan Teknologi, Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Negeri Gorontalo. Pembimbing Utama: Dr. Nurfaika, S.Si, M.Sc. dan Pembimbing Pendamping: Rusiyah, S.Pd., M.Sc. Tujuan penelitian ini adalah menganalisis secara spasial dinamika perubahan pola aliran air permukaan yang dipicu oleh perubahan topografi akibat kegiatan pertambangan di PT J Resources Bolaang Mongondow (PT JRBM). Penelitian ini menggunakan metode kualitatif deskriptif dengan pendekatan analisis spasial terpadu menggunakan perangkat lunak Surpac, Global Mapper, MapInfo, dan AutoCAD. Data penelitian mencakup data topografi temporal untuk periode Januari, Maret, Juni, dan September 2025, yang dilengkapi dengan pengamatan lapangan langsung. Hasil penelitian menunjukkan bahwa: (1) Kegiatan pertambangan secara langsung mengubah morfologi lahan, yang menyebabkan pergeseran batas hidrologis (daerah tangkapan air), yang kemudian berdampak pada transisi pola aliran permukaan dari pola aliran alami (dendritik) menjadi pola aliran buatan yang sepenuhnya dikendalikan oleh rekayasa operasional. (2) Dinamika arah aliran di kawasan pertambangan aktif tidak hanya dipengaruhi oleh kemiringan lereng makro, tetapi secara khusus ditentukan oleh fitur-fitur teknis buatan seperti parit jalan, tanggul pengaman, dan kemiringan jalan angkut. (3) Perubahan topografi mengakibatkan fluktuasi ukuran daerah tangkapan air kolam sedimentasi, di mana terjadi pengurangan yang     signifikan sebesar 19,1 Ha di CP-7 karena aliran terhalang ke Pit Sump 03, dan pengurangan sebesar 8,3 Ha di CP-6 karena rekayasa tumpukan di area Static Heap Leach Pad (SHLP). (4) Penggunaan perangkat lunak analisis kontur geospasial harus diintegrasikan dengan validasi kondisi faktual di lapangan, karena modifikasi mikrotopografi buatan manusia merupakan faktor paling dominan dalam mengalihkan arah aliran air di area operasional.

Abstract

Digital transformation demands a shift in Geography learning from theoretical memorization to the mastery of practical spatial skills. This community service aims to improve the geospatial literacy of SMAN 2 Konawe Selatan students through Google Earth training for determining coordinate points. The method applied was a participatory training based on direct practice, which included concept reinforcement, demonstrations, independent/group practice, and evaluations using pretest and posttest. The results of the service showed a significant increase in geospatial literacy, where the students' average score jumped from 62 (pretest) to 86 (posttest) with an N-Gain value of 0.63 (medium category). Furthermore, as many as 86.7% of students successfully determined the coordinate points of contextual locations with precision through worksheets. In conclusion, Google Earth training is effective as an interactive learning medium that bridges theory and spatial practice for students.

Abstract

This research was conducted in Olele Village, Kabila Bone District, Bone Bolango Regency, Gorontalo Province. The study aims to analyze the relationship between lithology and groundwater hydrochemistry and to determine the groundwater hydrochemical facies. The methods used include surface geological mapping, groundwater chemical analysis at the Chemistry Laboratory of Universitas Negeri Gorontalo, and determination of hydrochemical facies using the Piper trilinear diagram. The results of groundwater chemical analysis plotted on the Piper diagram indicate that the hydrochemical facies in the study area is dominated by the Na–Cl facies. This facies suggests the influence of seawater mixing or seawater intrusion into the coastal aquifer system. This condition is reinforced by reef limestone lithology, which has high porosity and permeability, allowing seawater to enter the shallow groundwater aquifer. Thus, reef limestone lithology plays an important role in controlling the aquifer system and influencing groundwater hydrochemical characteristics. Interaction between groundwater and the coastal environment causes groundwater to evolve toward the Na–Cl facies.

Abstract

This descriptive qualitative study aims to describe the critical thinking skills of grade X students in learning Anthroposphere material through case-based deep learning at SMAN 2 Konawe Selatan. The study involved 24 students and one geography teacher. Data were collected through classroom observation, case-based essay tests, interviews, and documentation, then analyzed descriptively using triangulation of techniques and sources. The results show that the learning process reflected meaningful, mindful, and joyful learning. Students achieved an average score of 92.71, with all students categorized as very critical. The findings indicate that contextual cases can support students in interpreting geographic phenomena, analyzing causal relationships, drawing evidence-based conclusions, evaluating alternative solutions, and presenting reflective explanations of population and environmental issues.

Abstract

Scientific publication is an essential research output that serves as a medium for disseminating research findings while strengthening academic culture in higher education. However, many students still have limited understanding of the publication process, particularly in preparing journal articles, selecting appropriate journals, understanding publication ethics, and submitting manuscripts through the Open Journal System (OJS). This community engagement program aimed to strengthen the understanding of scientific publication among students of the Geography Study Program, Universitas Negeri Gorontalo, as the final output of their research. The program was conducted through lectures, interactive discussions, question-and-answer sessions, and the sharing of publication experiences. Evaluation was carried out through observation of participants' engagement during the activity and feedback collected at the end of the session. The results showed that participants developed a better understanding of scientific article structure, publication ethics, journal selection strategies, reference management applications, and manuscript submission through OJS. This activity is expected to improve students' readiness to publish their research findings and foster a stronger culture of scientific publication within the university.

Abstract

Background: Groundwater serves as a fundamental resource for drinking, agriculture, and industrial processes, yet anthropogenic activities and environmental changes increasingly threaten its sustainability. This study, conducted in the Limboto Alluvial Plain, Indonesia, aimed to identify and map groundwater vulnerability by enhancing the traditional DRASTIC framework through the integration of the Multi-Influencing Factor (MIF) method. The implementation of the MIF method is proposed to improve the accuracy of the weighing system in evaluating the groundwater vulnerability. Methods: Seven thematic layers—depth to water, net recharge, aquifer media, soil media, topography, impact of the vadose zone, and hydraulic conductivity—were generated and integrated using Geographic Information Systems (GIS). The research replaced the conventional static weighting system with a dynamic MIF approach to systematically evaluate the interdependencies between hydrogeological parameters. The model's accuracy was empirically validated using nitrate concentration proxies to correlate high-risk zones with actual contamination levels. Findings: The study revealed three distinct vulnerability classes: low, moderate, and high. High-vulnerability zones were primarily identified in the central and southern regions, characterized by shallow water tables and highly permeable media. Validation results showed a strong correlation between these delineated high-risk zones and elevated nitrate concentrations, confirming the model's reliability in predicting sensitive areas. Conclusion: The study strongly recommends adopting this enhanced MIF-DRASTIC framework as a robust tool for sustainable groundwater management and land-use planning. It provides policymakers with a precise tool for mitigating contamination in alluvial contexts, though further longitudinal data could refine the model's temporal accuracy. Novelty/Originality of this article: This research is novel because it systematically addresses the inherent limitations of the static DRASTIC model by introducing dynamic weighting through the MIF approach. It uniquely integrates hydrogeological interdependencies within the Limboto Alluvial Plain, offering a more site-specific and refined methodology for groundwater protection that is more adaptable than traditional frameworks.
