Abstract
This study aims to analyze the influence of motivation, work discipline, and supervision on the work effectiveness of civil servants (ASN) at the Kediri Regency Trade Office. The research employed a quantitative approach with an associative design. The population consisted of 55 civil servants, all of whom were included as the sample using a saturated sampling technique. Data were collected using a five-point Likert scale questionnaire and analyzed through validity and reliability tests, classical assumption tests, multiple linear regression, t-tests, F-tests, and the coefficient of determination (Rยฒ). The results revealed that motivation, work discipline, and supervision each had a positive and significant partial effect on work effectiveness. Simultaneously, the three variables also had a significant effect on work effectiveness. The coefficient of determination (Rยฒ) value of 0.488 indicates that motivation, work discipline, and supervision explain 48.8% of the variation in work effectiveness, while the remaining 51.2% is influenced by other factors not examined in this study. These findings highlight the importance of strengthening motivation, enforcing consistent work discipline, and implementing effective supervision to enhance civil servantsโ work effectiveness.
