<![CDATA[Civil servant performance is an important determinant of public organizational effectiveness because it is directly related to task accomplishment and service quality. This study examines the effects of Employee Commitment and Job Satisfaction on the Performance of civil servants at the Kediri Middle-Type Customs and Excise Supervision and Service Office. A quantitative, verificative, explanatory research design was employed. The population comprised 82 employees, and 50 employees were selected through purposive sampling based on three criteria: not being assigned outside the city, holding an executive position, and being under 40 years of age. Data were collected using a Likert-scale questionnaire and analyzed with Structural Equation Modeling-Partial Least Squares (SEM-PLS) using SmartPLS 4.0. The results show that Employee Commitment has a positive and significant effect on Performance (β = 0.702; t = 7.183; p < 0.001), while Job Satisfaction also has a positive and significant effect (β = 0.274; t = 2.650; p = 0.008). The R² value for Performance is 0.918, indicating that the two predictors explain 91.8% of the variance. Employee Commitment is the dominant predictor with an f² value of 1.045, while Job Satisfaction has an f² value of 0.159. The study concludes that strengthening employees’ attachment, loyalty, sense of belonging, and responsibility, together with maintaining satisfaction with job-related aspects, can support higher civil servant performance. Interpretation should nevertheless consider the incomplete discriminant validity and the VIF value of 5.735 for both predictors]]>
