Pengaruh Budaya Organisasi, Kepemimpinan, dan Kompetensi Karyawan Terhadap Kinerja Karyawan pada PT. Wastewater Management Service Makassar

This study examines the influence of organizational culture, leadership, and employee competence on employee performance at PT. Wastewater Management Service Makassar. Utilizing a quantitative approach with a causal-associative design, the study involved all employees (N=45) as the sample, using primary data collected through questionnaires and secondary data from company documentation. Data analysis included classical assumption tests (normality, multicollinearity, and heteroscedasticity), instrument validity and reliability tests, and multiple linear regression analysis. The findings indicate that all classical assumptions for regression analysis were met. The research instruments were declared valid and reliable. The multiple linear regression analysis showed that leadership had a positive and significant effect on employee performance (p < 0.001). Conversely, the influence of organizational culture (p = 0.066) and competence (p = 0.303) on employee performance was not statistically significant when considered individually. However, collectively, the three independent variables had a significant effect on employee performance (p < 0.001), with an R² value of 0.758. This indicates that 75.8% of the variance in employee performance can be explained by these variables. The findings highlight the importance of effective leadership in enhancing performance at PT. Wastewater Management Service, even though organizational culture and competence did not show significant individual effects in this study. The study recommends improving leadership quality through structured training and development programs, as well as evaluating and enhancing organizational culture and employee competency development initiatives to optimize performance. Differences in these findings compared to previous studies are discussed in the context of the specific characteristics of PT. Wastewater Management Service.
