Understanding Driver Performance: The Mediating Impact of Discipline on Motivation, Skills, and Work Culture at PT Hiba Logistic

This study investigates the mediating role of discipline in the relationship between motivation, work skills, work culture, and drivers' performance at PT Hiba Logistic (Hilog). Utilizing an explanatory research design, this study explores causal relationships among the variables to test hypotheses and uncover new insights. The independent variables include motivation (X1), work skills (X2), and work culture (X3), with discipline (Z) serving as the mediating variable and performance (Y) as the dependent variable. Structural Equation Modeling with Partial Least Squares (SEM-PLS) was employed for data analysis using the SmartPLS 4.0 application. The findings reveal the following: (1) motivation significantly influences discipline, (2) work skills do not significantly influence discipline, (3) work culture significantly influences discipline, (4) motivation does not significantly influence performance, (5) work skills do not significantly influence performance, (6) work culture significantly influences performance, (7) discipline significantly influences performance, (8) discipline significantly mediates the relationship between motivation and performance, (9) discipline does not significantly mediate the relationship between work skills and performance, and (10) discipline significantly mediates the relationship between work culture and performance. These findings provide practical insights into the critical role of discipline in driver performance and its implications for enhancing workplace dynamics. e job skills, and performance variables [10]. Discipline has a significant effect on mediating work culture and performance variables
