This study analyzes the direct and indirect effects of motivation, work ability, and compensation on the performance of soldiers at the Pacitan Naval Base, with organizational commitment as a mediating variable. It is based on the hypothesis that these three factors positively influence performance both directly and through organizational commitment. The study employed a quantitative causal-explanatory design, encompassing all 44 soldiers at the base through a saturation sample method. Structured questionnaires were used to collect data, and Structural Equation ModelingPartial Least Squares (SEM-PLS) was used to analyze it.Five variables were examined: motivation, work ability, compensation, organizational commitment, and performance. All measurement instruments were valid and reliable. The findings demonstrate that motivation, job capability, and compensation exert substantial direct influences on both performance and organizational commitment. Nonetheless, only work ability exhibits a large indirect effect on performance via organizational commitment.. The coefficient of determination (R²) values are 0.824 for organizational commitment and 0.880 for performance, with a Q² value of 0.979, demonstrating high predictive relevance. These findings emphasize the need to strengthen soldiers work ability, motivation, and compensation to enhance performance. Organizational commitment, while supportive, plays a complementary role. The study underscores the value of integrating psychological and organizational strategies in military human resource management to achieve optimal performance outcomes.
