Pengaruh Self-Efficacy dan Stres Kerja terhadap Kinerja Karyawan pada Kantor Pusat PT Kimia Farma Diagnostika Jakarta

Abstract

Human resources are a strategic asset that plays an important role in determining a company's success, including PT Kimia Farma Diagnostika Jakarta. Based on observations conducted during an internship, employees were found to work beyond the designated working hours, indicating work demands that may contribute to work stress. In addition, employees' self-efficacy is an important aspect to consider in supporting their performance when facing work demands. This study aims to determine the effect of self-efficacy and work stress on employee performance at PT Kimia Farma Diagnostika Jakarta, both partially and simultaneously. This study employed a quantitative method with an associative approach. Data were collected through questionnaires distributed to 42 employees and analyzed using validity tests, reliability tests, classical assumption tests, and multiple linear regression analysis with the assistance of SPSS. The results showed that self-efficacy had a positive and significant effect on employee performance, while work stress also had a positive and significant effect on employee performance. Simultaneously, self-efficacy and work stress had a positive and significant effect on employee performance, with a contribution of 86.6%, while the remaining 13.4% was influenced by other factors outside the scope of this study. These findings imply that efforts to improve employee performance should consider employees' confidence in their ability to complete tasks as well as the work stress they experience.
