Abstract

This study aims to identify potential hazards and establish priority risk control strategies in nickel mining operations using the Hazard Identification, Risk Assessment, and Determining Control (HIRADC) method combined with the Fuzzy Technique for Order Preference by Similarity to Ideal Solution (Fuzzy TOPSIS) approach. The HIRADC analysis revealed several activities with high risk levels, including girder lifting, material/piping unloading, maintenance lifting, stone crushing, civil works, cathodic installation, and material loading/unloading operations. The most significant hazards identified were falling or being struck by objects, falls from heights, electrical shock, collisions with heavy equipment, and entrapment by materials. Five hazards were classified as very high risk, including falling objects (score 25), while falls from heights, electrical shock, collisions, and entrapment each scored 20. To determine mitigation priorities, the Fuzzy TOPSIS method was applied, resulting in recommended risk control strategies. The top-ranked strategies include ensuring areas are clear of falling objects and verifying lifting equipment capacity (C1), providing lifelines and full-body harnesses (C2), installing standard-compliant electrical panels with grounding (C3), segregating pedestrian pathways from heavy equipment routes (C4), and installing emergency stops and machine guards (C5). The findings demonstrate that integrating HIRADC with Fuzzy TOPSIS offers a systematic approach for effective risk management in nickel mining operations.

Abstract

Generation Z learners, born into an era of ubiquitous digital technology, require robust digital-literacy skills to participate effectively in education and society. However, many students in Islamic elementary schools (madrasah ibtidaiyah) still struggle with basic computer operation, especially when confronted with computer-based testing environments. This study aimed to upgrade the digital literacy of female students at MI Al Fatah II through a structured, hands-on Basic Computer Training (BCT) program. The training emphasized fundamental computer use, file management, text editing, and online-examination simulation. A participatory action-research design was adopted, involving 25 students over three weeks. Quantitative data were collected via pre- and post-tests, and qualitative data through observation and reflective interviews. The average literacy score increased from 48.2 to 86.7, yielding a normalized gain of 0.74 (high effectiveness). Students also exhibited enhanced self-confidence and ethical awareness in digital environments. The findings highlight that gender-responsive, context-based digital-literacy programs can effectively prepare young learners in faith-based schools to engage in online learning ecosystems and align with Indonesia’s Merdeka Belajar policy and the Sustainable Development Goals (SDGs 4 & 9).

Abstract

The rapid progress of information and communication technology in the era of the Fourth Industrial Revolution demands that younger generations possess strong technological literacy to adapt effectively to ongoing digital transformation. This study aims to enhance students’ technological literacy at SMPN 1 Karangrejo through socialization and practical activities using appropriate technology (AT). The research adopts a participatory descriptive method involving 40 junior high school students. The activities consist of four stages: preliminary observation, interactive socialization, hands-on construction of appropriate technology tools, and evaluation. Quantitative results show an average technological literacy increase of 35.2% with a normalized gain score of 0.71, indicating high effectiveness. Qualitative findings reveal enhanced student motivation, creativity, collaboration, and environmental awareness. The study demonstrates that project-based AT learning effectively transforms students’ technological understanding and attitudes, making it replicable in other schools with local adjustments.
