Human Resource Performance Improvement Model Based on K3 Management System, Work Culture and Job Satisfaction at PLN UP3 Tolitoli
Abstract
The performance of Human Resources (HR) in the Technical Service Unit (Yantek) at PT PLN UP3 Tolitoli is a critical element in ensuring reliable electricity services to the community. However, challenges such as non-compliance with Occupational Health and Safety (OHS) procedures, poorly internalized work culture, and low job satisfaction hinder the improvement of employee performance. This study aims to identify and analyze the direct and indirect effects of the Occupational Health and Safety Management System and Work Culture on HR Performance, with Job Satisfaction as a mediating variable. The novelty of this research lies in the integration of job satisfaction as a mediating variable between OHS management systems and work culture toward HR performance—an approach rarely explored specifically in the electricity sector within remote areas such as Tolitoli. This study provides empirical evidence to fill the research gap related to how technical field work culture and safety systems affect operational performance through employees’ psychological well-being. A quantitative method was applied using the Partial Least Square Structural Equation Modeling (PLS-SEM) approach. Data were collected from 100 Yantek employees at PT PLN UP3 Tolitoli using a structured questionnaire. The results of this study show that out of the seven proposed hypotheses, six are accepted and one is rejected. The Occupational Health and Safety Management System (SMK3) does not significantly affect Job Satisfaction, as indicated by a P-Value of 0.052 > 0.05 and a T-Statistic of 1.898 < 1.96. Organizational Culture has a positive and significant effect on Job Satisfaction with a P-Value of 0.000 < 0.05 and a T-Statistic of 5.601 > 1.96. The Occupational Health and Safety Management System also has a positive and significant effect on Human Resource Performance, as shown by a P-Value of 0.004 < 0.05 and a T-Statistic of 2.191 > 1.96. Organizational Culture has a positive and significant effect on Human Resource Performance, with a P-Value of 0.000 < 0.05 and a T-Statistic of 3.565 > 1.96. Job Satisfaction also positively and significantly affects Human Resource Performance, supported by a P-Value of 0.000 < 0.05 and a T-Statistic of 4.468 > 1.96.
