ABSTRACT: This study aims to analyze the impact of organizational commitment on employee performance with job satisfaction as a mediating variable among non-ASN employees at the Department of Transportation of Surabaya City, Motor Vehicle Testing Unit Tandes. The research method used is quantitative with an explanatory survey design. Data were collected from 45 non-ASN employees using structured questionnaires with a Likert scale. Data analysis was performed using Structural Equation Modeling-Partial Least Square (SEM-PLS). The results show that organizational commitment has a positive and significant effect on employee performance (β = 0.42, p < 0.001), both directly and through job satisfaction as a mediating variable. Job satisfaction significantly mediates the relationship between organizational commitment and employee performance (β = 0.26, p < 0.05). The model explains 45.1% of the variance in employee performance (R² = 0.451). This research highlights the importance of fostering a supportive organizational culture and improving job satisfaction to enhance employee performance and overall organizational effectiveness.
