The Effect of Professionalism on Employee Performance at the Department of Manpower, Industry, and Trade of Binjai City

Abstract

This study investigates the effect of professionalism on employee performance at the Department of Manpower, Industry, and Trade of Binjai City. A total of 50 respondents participated in this research, and the data were analyzed using descriptive statistics and simple linear regression analysis. The descriptive findings indicate that both professionalism (M = 4.70; SD = 0.43) and employee performance (M = 4.83; SD = 0.50) were rated at high levels, suggesting that employees demonstrate strong professional attitudes and achieve favorable performance outcomes. The regression analysis reveals that professionalism has a significant positive effect on employee performance, with a regression coefficient (B = 1.142), standardized Beta (β = 0.728), and t-value (8.367). These findings indicate that every one-unit increase in professionalism contributes to a 1.142-unit increase in employee performance, confirming the crucial role of professionalism in enhancing work outcomes. The constant value (9.105) also indicates that employee performance remains at a positive baseline level; however, increased professionalism further strengthens and improves overall performance. The model summary shows a correlation coefficient (R = 0.732) and a coefficient of determination (R² = 0.536), meaning that professionalism explains 53.6% of the variance in employee performance, while the remaining 46.4% is influenced by other factors not examined in this study. Overall, the findings highlight that professionalism is a significant determinant of employee performance in public sector institutions and should be continuously reinforced to improve organizational effectiveness.
