Abstract

Various welding accident cases indicate hazardous conditions, highlighting the need for occupational health and safety management training for students at SMKN 2 Pekanbaru. This study adopts a quantitative, cross-sectional design, using a survey of all 39 students in the 12th-grade welding department. The study adopts a non-probability sampling method, using saturated sampling. Data were collected using a questionnaire to assess students' understanding of occupational health and safety management in welding practices. The study analyzes the data using multiple linear regression processed through SPSS. The results show that there is no partial effect of health management on the implementation of welding practices, as the t statistic < the t table value (2.055 < 2.208). At the same time, occupational safety affects the implementation of welding practices (4.598 > 2.208). Additionally, there is a simultaneous effect (F test) of health management and occupational safety on the implementation of welding practices, where F count > F table (15.330 > 3.25). Health management does not influence welding practices, whereas occupational safety does. It is advisable to provide health management training and conduct regular occupational safety training before students begin welding practices.

Abstract

The increasing use of digital technology in higher education has intensified screen exposure among lecturers, potentially affecting workload and health outcomes. This study examines the effect of screen exposure on lecturers’ health, with workload as a mediating variable, at the Indonesian University of Science and Technology. A quantitative causal-associative design was employed using a census method involving 65 permanent lecturers. Data were collected through an online questionnaire and analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS). The analysis included validity and reliability testing, coefficient of determination (R²), predictive relevance (Q²), and hypothesis testing. The results indicate that screen exposure has a positive and significant effect on workload and a direct significant effect on lecturers’ health. However, workload does not have a significant direct effect on health and does not mediate the relationship between screen exposure and health. These findings suggest that adverse health effects related to screen exposure occur primarily through direct physiological and visual mechanisms. The model demonstrates strong explanatory and predictive power. This study contributes to empirical evidence on digital workload and occupational health in Indonesian higher education and offers practical implications for ergonomic and screen time management policies
