Abstract

This study aims to examine the impact of work environment (X1), work motivation (X2), and job satisfaction (X3) on teacher performance (Y) at SMP Negeri 3 in South Tangerang City. The study employs a quantitative approach with a survey method, and data were collected through the distribution of questionnaires to 40 teachers. The analysis technique used is multiple linear regression with the assistance of SPSS software version 27 to test the impact of independent variables on the dependent variable. The results indicate that the work environment significantly affects teacher performance, with a regression coefficient of 0.534, meaning that the better the work environment, the higher the teacher's performance. Meanwhile, work motivation (X2) does not have a significant effect on teacher performance, with a low coefficient of 0.184, suggesting that motivation is not the main factor influencing teacher performance at SMP Negeri 3 in South Tangerang City. In contrast, job satisfaction (X3) has a positive and significant impact on teacher performance, with a coefficient of 0.559, indicating that higher job satisfaction leads to better performance. The regression equation obtained is Y = -12.759 + 0.534 X1 + 0.184 X2 + 0.559 X3, which reflects the influence of each factor on teacher performance. Based on these results, it can be concluded that the work environment and job satisfaction are important factors in improving teacher performance, while work motivation does not have a significant impact. Therefore, the school administration should focus more on improving the work environment and enhancing teacher job satisfaction to encourage better performance. This study provides recommendations for school managers to address these two factors in efforts to improve teacher performance.

Abstract

Employee performance is a crucial factor in supporting a company's success, particularly in the tourism sector, which demands optimal human resource quality. Factors such as work motivation, work environment, and work discipline are believed to significantly influence employee performance. However, the extent to which these three factors contribute to improved employee performance in tourism companies still requires empirical research. This study aims to determine the partial effect of work motivation, work environment, and work discipline on employee performance at PT. Wisata Titiannusantara Pelangi. The study population comprised all 40 employees, with the sampling technique using the saturation method (sampling the entire population). Data analysis was performed using multiple linear regression processed using SPSS version 22. The results show that work motivation has a positive and significant effect on employee performance, meaning that the higher an employee's motivation, the better their performance. The work environment also proved to have a positive and significant effect on performance, indicating that a comfortable and supportive work environment can improve employee performance. Furthermore, work discipline has a positive and significant effect on employee performance, indicating that discipline in carrying out tasks contributes significantly to achieving optimal work results. Overall, this study confirms that motivation, work environment, and work discipline are important factors that must be considered by management in efforts to improve employee performance, especially in companies operating in the tourism sector.
