Abstract

Occupational Safety and Health (OSH) in vocational school workshops represents an urgent priority given that students interact directly with high-risk equipment such as grinding machines, yet often demonstrate low compliance with safety protocols. This research aims to identify failure modes on grinding machines in SMKN 1 Jenangan workshop and formulate evidence-based risk control recommendations. A quantitative descriptive approach using Failure Mode and Effects Analysis (FMEA) was employed, involving 10 purposively selected respondents (practical instructors and technicians). The research instrument was validated using Content Validity Index (CVI) by three experts in occupational safety and mechanical engineering. Results identified 15 failure modes with CVI = 1.0 (perfect validity). Risk Priority Number analysis revealed a positive risk distribution: 13 modes fell into low-risk category (RPN ≤ 50), 2 modes into medium-risk category (RPN 50-100) including non-compliance with protective gloves (RPN 58.21) and safety glasses (RPN 50.51), and no modes reached high-risk category (RPN ≥ 100). Critical finding demonstrates that the greatest risks originated from human behavioral factors, specifically non-compliance with Personal Protective Equipment (PPE) usage, rather than machine technical components. Risk control recommendations focus on three pillars: (1) intensifying direct supervision of students, (2) implementing continuous safety education programs with positive reinforcement, and (3) transforming safety culture in the workshop. This research contributes empirical evidence on risk profiles in vocational school workshops and emphasizes the importance of behavior-based interventions rather than technical improvements in enhancing occupational safety in vocational education settings.

Abstract

The advancement of educational technology has led to the development of innovative learning media to improve student engagement and learning outcomes. This study aimed to develop and evaluate the feasibility and effectiveness of PowerPoint Hyperlink-based interactive learning media for milling machine material. The research employed the Research and Development (R&D) method using the 4D model, consisting of the Define, Design, and Develop stages. The research subjects were 20 tenth-grade students of the Machining Engineering Department at SMK Muhammadiyah 1 Kepanjen. The research instruments included expert validation sheets, questionnaires, pretest-posttest assessments, and documentation. Data were analyzed descriptively, while the effectiveness of the learning media was evaluated using the Wilcoxon Signed Rank Test and N-gain analysis. The results indicated that the learning media achieved a feasibility score of 87.2%, categorized as highly feasible, based on expert evaluations. The Wilcoxon Signed Rank Test revealed a significant difference between the pretest and posttest scores (p = 0.000 < 0.05). Furthermore, the N-gain score of 0.48 was classified as moderate, indicating that the learning media effectively improved students' learning outcomes. Therefore, the PowerPoint Hyperlink-based interactive learning media is feasible and effective as an alternative learning resource for milling machine instruction in vocational high schools.
