Abstract

This community service program aims to enhance the understanding of Geology Engineering students at Universitas Sulawesi Tenggara regarding environmentally sustainable mining practices. The education was delivered through lectures, interactive discussions, and local case studies relevant to mining activities in Southeast Sulawesi. These methods were chosen to encourage active participation and ensure the materials were contextually relevant to the students’ local environment and future professional field. The results indicate that students gained new insights into the implementation of good mining practice, post-mining reclamation, and mining and environmental regulations, which fostered greater awareness of the environmental and social impacts of mining. In addition, the program facilitated critical thinking and encouraged students to analyze real-world mining problems from a sustainability perspective. Consequently, this program not only improved students’ environmental literacy but also developed a sense of responsibility and commitment to supporting sustainable mining practices. It is expected that the knowledge gained will influence their future decisions as professionals in the mining sector, promoting a more sustainable and responsible industry.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pemahaman mahasiswa Teknik Geologi Universitas Sulawesi Tenggara mengenai pertambangan berwawasan lingkungan. Edukasi diberikan melalui penyuluhan, diskusi interaktif, dan studi kasus lokal yang relevan dengan kondisi pertambangan di Sulawesi Tenggara. Hasil kegiatan menunjukkan bahwa mahasiswa memperoleh wawasan baru terkait penerapan good mining practice, reklamasi pascatambang, serta regulasi pertambangan dan lingkungan, sehingga kesadaran kritis mereka terhadap dampak lingkungan dan sosial dari pertambangan semakin meningkat. Dengan demikian, kegiatan ini tidak hanya menambah literasi lingkungan mahasiswa, tetapi juga membentuk sikap peduli dan tanggung jawab dalam mendukung praktik pertambangan yang berkelanjutan.

Abstract

This study investigates the influence of bedrock on nickel (Ni) content in laterite deposits in the Lameruru Region, Langgikima District, North Konawe Regency, Southeast Sulawesi Province, Indonesia. The research area is dominated by ultramafic rocks, which are potential sources of laterite nickel. The study employs literature review, field surveys for lithological data collection and representative sampling, petrographic analysis to determine mineral composition and rock types, and geochemical analysis using X-Ray Fluorescence (XRF) to determine nickel content in the rocks. The results show that the bedrock in the study area consists of harzburgite and olivine pyroxenite. Harzburgite, occupying approximately 72.72% of the area, is composed of 54-78% olivine, 15-45% orthopyroxene, 6% clinopyroxene, and accessory minerals, while olivine pyroxenite, occupying about 27.28% of the area, is composed of 27% olivine, 49% orthopyroxene, 17% serpentine, and 7% spinel. Geochemical analysis reveals that harzburgite has higher Ni content (0.10-0.16%) compared to olivine pyroxenite (0.03-0.10%). The distribution of Ni in the bedrock and saprolite is directly proportional, with higher Ni content in harzburgite in both zones. The study concludes that the type of bedrock greatly influences the nickel content in laterite deposits, with harzburgite having a higher Ni content due to its higher percentage of olivine minerals, which are the main hosts of nickel in ultramafic rocks.

Abstract

A rock description training has been conducted at SMK Negeri 6 Kendari to enhance fundamental petrology knowledge and descriptive skills among students in the Mining Geology program. This training involved 47 senior-level students and was implemented through several stages, including preparation, material presentation, rock description practicum, and outcome evaluation via written exam and analytical rubric assessment. The training comprised theoretical and practical sessions focused on the description of three rock groups (igneous, sedimentary, and metamorphic) using hand specimens and thin sections. The analysis demonstrates a significant enhancement in students' comprehension, as reflected in the increase in the average post-test score to 62.02, compared to the pre-test score of 45.74. An improvement in descriptive skills was also evident based on the evaluation rubric, with a greater number of students achieving the "Intermediate" proficiency level, characterized by scores exceeding 39, following the training. Statistical analysis using a paired t-test revealed a p-value <0.05, with the t-statistic substantially exceeding the critical threshold, affirming that the training had a significant impact on improving students’ knowledge and descriptive competencies in rock examination. It is recommended that future training programs focus on advanced modules, particularly those emphasizing rock interpretation, to further enhance students’ proficiency in rock description.
