This study aimed to examine and analyze the effects of competence, discipline, and organizational culture on the performance of Small and Medium Industries (SMIs) in Jayapura City, with work motivation as a mediating variable. The study employed a quantitative approach using a survey method. The population consisted of SMI business actors in Jayapura City, with a sample of 233 respondents selected through purposive sampling. Data were collected using questionnaires and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS 4. The results showed that (1) competence did not have a significant effect on work motivation, indicating that higher competence among business actors did not necessarily increase their work motivation; (2) discipline had a significant positive effect on work motivation, indicating that higher levels of discipline were associated with greater work motivation; (3) organizational culture had a significant positive effect on work motivation, indicating that stronger organizational cultural values enhanced work motivation; (4) competence had a significant direct effect on SMI performance but did not have a significant indirect effect through work motivation; (5) discipline had significant direct and indirect effects on SMI performance through work motivation; (6) organizational culture had significant direct and indirect effects on SMI performance through work motivation; and (7) work motivation had a significant effect on SMI performance. These findings suggest that improving SMI performance requires an integrated approach that combines competence development, discipline enhancement, organizational culture strengthening, and increased work motivation.
