Abstract

Introduction: PT PAL Indonesia is one of the largest shipyard industries in Indonesia, Based on the results of the survey conducted, there were several unsafe acts and unsafe conditions observed. The aims of this study aim to analyze the effect of personality, characteristics of individuals and safety management practices on safety performance of workers in the Commercial Ship Division of PT PAL Indonesia Surabaya. Method: This study used a cross-sectional design and simple random sampling method, involving 104 worker samples from a population of 139 workers. The dependent variable was personal safety performance, while the independent variables were personal awareness, safety management practices safety training and individual characteristics. Primary data were collected through questionnaires, observations and interviews. This study includes univariate analysis, bivariate analysis with Chi-square test and multivariate analysis using logistic regression analysis. Results: Based on the results of logistic regression analysis, the effect of conscientiousness personality with safety performance (ρ=0.013), the effect of safety management practices with safety training (ρ=0.000), the effect of age variables with safety performance (ρ=0.024) and the effect of working period variables with safety performance (ρ=0.024). Conclusion: There are effects of conscientiousness, personality, age, working period, safety management practices, and safety training on safety performance of workers at PT PAL Indonesia in 2023. This research can improve work safety performance by understanding the factors that influence it and companies can design more effective safety strategies.

Abstract

Musculoskeletal Disorders (MSDs) referred to complaints affecting the muscles and bones, ranging from sprains to chronic disorders that carried a risk of disability. Proper ergonomic implementation supported workers' health, comfort, and productivity, while poor ergonomics could trigger complaints. Identifying work positions, processes, and layouts was necessary to prevent MSDs. This study analyzed the effect of Workplace Stretching Exercise (WSE) on MSDs complaints among building construction project workers in Malang Regency. This study employed a quantitative approach with a Quasi-Experimental design and the Pretest-Posttest Control Group method. The study results indicated differences in MSDs complaints before and after the WSE intervention, demonstrating the effectiveness of the intervention. Ordinal regression analysis showed that several factors had a significant effect on MSDs complaints, including age 17-25 years (ρ=0.016), age 26-35 years (ρ=0.004), very low work posture (ρ=0.006), low work posture (ρ=0.008), work duration (ρ=0.007), low workload (ρ=0.023), moderate workload (ρ=0.015), and the WSE intervention (ρ=0.020). These findings indicated that, in addition to individual and work-related factors, the implementation of WSE played a role in reducing MSDs complaints among building construction project workers in Malang Regency. The researchers recommended that workers maintain optimal body posture, apply safe lifting techniques, avoid prolonged static positions, and perform regular stretching exercises as a preventive measure against musculoskeletal injuries

Abstract

Musculoskeletal Disorders (MSDs) are complaints involving muscles and bones, ranging from sprains to chronic conditions that may lead to disability. Proper ergonomic implementation promotes workers’ health, comfort, and productivity, while poor ergonomics can increase MSD risk. This study aimed to analyze the effect of Workplace Stretching Exercise (WSE) on MSD complaints among construction workers in Malang Regency. A quantitative approach with a quasi-experimental pretest–posttest control group design was applied. Of 94 workers, 76 were selected using simple random sampling. Data covered individual (age, tenure, BMI, habits) and work-related factors (posture, duration, workload). The dependent variable was MSD complaints before and after WSE intervention. Statistical analysis using ordinal regression revealed a significant decrease in MSD complaints after WSE. Factors significantly associated with reduced MSDs included younger age, better posture, shorter work duration, lower workload, and the WSE intervention itself (p < 0.05).
