Methods: This research used a non-equivalent control group quasi-experimental study design, with a purposive sampling technique and a sample of 30 students in the control group and 31 students in the treatment group. Interventions involve OSH education through Youth4OSH e-learning, which is provided three times over three weeks. Data analysis utilized the Wilcoxon signed-rank test and Mann-Whitney U Test.
 Results: The results of the Wilcoxon signed-rank test showed that there was an increase in the scores of knowledge (p= 0.000), attitudes (p= 0.000), and practices (p= 0.000) in the treatment group. Furthermore, differences in enhancement scores of knowledge, attitudes, and practices between the treatment group and the control group are observed using the Mann-Whitney U test, which showed a p-value of 0.000 (p<0.05).
Conclusions: There were differences in knowledge, attitudes, and practices of safety behavior before and after receiving Youth4OSH e-learning education.
