Abstract
This study aims to examine the effect of work discipline, work motivation, and career development on employee performance at PT Jaya Terus Abadi, North Lombok. This study employed a quantitative approach with a descriptive-associative research design. The population consisted of 39 employees, and saturated sampling was applied, involving all members of the population as respondents. Data were collected through questionnaires and analyzed using multiple linear regression with the assistance of IBM SPSS. The results indicate that work discipline has a positive and significant effect on employee performance. Work motivation also has a positive and significant effect on employee performance. Career development has a positive and significant effect on employee performance. Simultaneously, work discipline, work motivation, and career development have a positive and significant effect on employee performance. The coefficient of determination shows that the three independent variables explain 72.5% of the variation in employee performance, while the remaining 27.5% is explained by other factors outside the research model. These findings suggest that strengthening work discipline, enhancing employee motivation, and providing effective career development opportunities are important strategies for improving employee performance at PT Jaya Terus Abadi, North Lombok.
