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.

Abstract

Nikel dan Kobalt merupakan elemen penting dalam industri baterai listrik karena berperan sebagai bahan utama dalam pembuatan katoda baterai lithium-ion. Logam-logam ini umumnya ditemukan pada endapan bijih nikel laterit. Penelitian ini bertujuan untuk mengidentifikasi dan mengevaluasi potensi nilai ekonomi dari kandungan nikel dan kobalt sebagai bahan baku baterai listrik pada endapan bijih nikel laterit milik PT. Rizqi Biokas Pratama yang berlokasi di Kabupaten Konawe Utara, Sulawesi Tenggara. Penelitian ini menggunakan pendekatan kuantitatif dengan metode deskriptif analitis. Hasil penelitian menunjukkan bahwa kandungan nikel dan kobalt pada endapan nikel laterit memiliki potensi ekonomi yang signifikan. Untuk nikel, lapisan limonit memiliki potensi ekonomi sebesar USD 19.550.965 atau setara dengan Rp 310.917.430.537, sedangkan lapisan saprolit memiliki potensi sebesar USD 1.978.843 atau setara dengan Rp 31.469.375.560. Sementara itu, untuk kobalt, lapisan limonit memiliki potensi ekonomi mencapai USD 60.211.426 atau setara dengan Rp 957.537.484.403, sedangkan pada lapisan saprolit mencapai USD 103.792.752 atau setara dengan Rp 1.650.607.831.636.
