The Effect of Work Motivation, Work Environment on Sustainable Employee Performance Mediated by Job Satisfaction Passengers Service Division PT USS

This study examines the impact of work motivation and work environment on long-term employee performance, with job satisfaction serving as a mediator, involving 94 permanent employees of the Passengers Service Division at PT USS. The study was conducted because employees in the ground handling sector have a strategic role in supporting the smooth operation of flights and airport services; however, high workload dynamics, strict safety standards, and demanding working conditions can affect their job satisfaction and the sustainability of their performance. A standardized questionnaire with a 5-point Likert scale was used to obtain quantitative data, which was then analyzed using Structural Equation Modeling-Partial Least Squares with SmartPLS 4.0 software to test seven hypotheses. The findings reveal that work motivation and work environment have a positive and considerable impact on long-term employee performance, and that job satisfaction significantly moderates the impact of work motivation and work environment on long-term employee performance.
