This study aims to analyse the effect of intrinsic motivation and work discipline on employee performance with organisational commitment as an intervening variable at Puskesmas Siwalan, Pekalongan Regency. The research sample consisted of 58 employees, and the data were analysed using the Structural Equation Modeling (SEM) method with the Smart PLS tool. The results showed that intrinsic motivation and work discipline had a positive and significant effect on employee performance. Organisational commitment also proved to be a variable that mediates the relationship significantly. The findings underscore the importance of strengthening intrinsic motivation and work discipline as key factors for improving performance in the healthcare work environment. This study provides practical implications for health centre management to develop performance improvement strategies through strengthening employee motivation and commitment.
