Abstract

Employee performance is a key factor in supporting the success of public organizations, including the Medan Belawan Primary Tax Office, which plays a strategic role in tax services and state revenue. This study aims to analyze the effect of work discipline and work facilities on employee performance with work motivation as a mediating variable. The study used a quantitative approach with a survey method of all 100 employees of the Medan Belawan Primary Tax Office, so the sampling technique used was a census. Data were collected through questionnaires and analyzed using the Partial Least Squares (PLS) method with the help of SmartPLS software. The results show that work discipline has a positive and significant effect on employee performance and work motivation. Work facilities also have a positive and significant effect on employee performance and work motivation. Furthermore, work motivation has a positive and significant effect on employee performance. The indirect effect test showed that work motivation was able to mediate the effect of work discipline on employee performance, as well as mediate the effect of work facilities on employee performance. The coefficient of determination value showed that work discipline and work facilities were able to explain 35.9% of the variation in work motivation, while work discipline, work facilities, and work motivation together were able to explain 55.2% of the variation in employee performance. Based on these results, it can be concluded that improving the performance of employees at the Medan Belawan Tax Office does not only depend on the implementation of work discipline and the provision of adequate work facilities, but is also greatly influenced by the level of employee work motivation. Therefore, management is expected to strengthen disciplinary policies, improve the quality of work facilities, and create a work environment that can encourage employee motivation in order to improve performance and the quality of public services.

Abstract

The research analysis aims to analyze the organizational culture and work environment on employee performance at the Medan Perjuangan District Office. The data analysis technique used is the associative research method with the help of the SPSS version 23 program. This study uses multiple linear regression analysis. The sample in this study was 100 respondents. Primary data collection used a questionnaire. The results of the study indicate that the organizational culture variable has a t count of 3.651 and a t table of 1.984723, so t count > t table (3.651 > 1.984723) with sig. 0.000 < 0.05 so that the results of the study accept H1. It can be explained that the organizational culture variable (X1) influences the employee performance variable of the Medan Perjuangan Sub-district Office. The work environment variable has a t count of 2.345 and a t table of 1.984723, so t count > t table (2.345 > 1.984723) with sig. 0.021 < 0.05 so that the results of the study accept H1. It can be explained that the work environment variable (X2) influences the employee performance of the Medan Perjuangan Sub-district Office. The value obtained is f count = 92.290 > f table 3.09 with sig. 0.000 < 0.05. So it can be concluded that H1 is accepted. Where the variables of organizational culture (X1) and work environment (X2) simultaneously have a positive and significant effect on the performance of employees at the Medan Perjuangan District Office.

Abstract

This study aims to analyze the influence of organizational culture and rewards on employee performance with work motivation as a mediating variable at the National Narcotics Agency (BNN) of North Sumatra Province. Employee performance is an important factor in achieving organizational strategic goals, especially at the BNN, which faces the complexity of narcotics circulation and demands for quality rehabilitation services. Organizational culture and rewards are expected to influence employee performance directly and through work motivation. The type of research used is quantitative with a survey approach. The research population consists of all 84 permanent employees of the North Sumatra Provincial BNN. Data were collected through questionnaires and analyzed using Partial Least Squares (PLS). The results showed that organizational culture had a positive and significant effect on employee performance and work motivation. Rewards had a positive and significant effect on work motivation but did not significantly affect employee performance directly. Work motivation played a significant role as a mediator, so that organizational culture and rewards could improve employee performance through work motivation. The R² value shows that organizational culture, rewards, and work motivation can explain 91.9% of the variation in employee performance. These findings imply that the North Sumatra Provincial Narcotics Agency needs to strengthen its organizational culture, implement a fair reward system, and encourage employee work motivation through independence, autonomy, and recognition of their contributions. This approach is expected to improve employee performance consistently and professionally.

Abstract

The increasing global emphasis on sustainability has accelerated investments in renewable energy technologies, positioning sources like solar, wind, and hydroelectric power as vital alternatives to fossil fuels. Despite significant progress, integrating renewable energy into existing grids remains challenging due to variability in energy output, grid instability, and inefficiencies in energy storage systems. This study investigates the potential of machine learning (ML) to revolutionize the renewable energy sector by enhancing energy forecasting, grid management, and energy storage optimization. Using a combination of supervised learning, deep learning, and reinforcement learning techniques, we developed predictive and optimization models based on historical and real-time datasets. Additionally, structural equation modeling (SEM) with SmartPLS was employed to analyze the relationships between key variables, such as machine learning algorithms, renewable energy sources, sustainability performance, and operational efficiency. The results indicate that machine learning significantly improves energy forecasting accuracy, grid reliability, and storage efficiency, with R-squared values of 0.685 for operational efficiency and 0.588 for sustainability performance. These findings highlight the transformative role of ML in optimizing renewable energy systems and achieving sustainable energy goals. While ML offers promising solutions for renewable energy challenges, further research is needed to address real-time data integration, model scalability, and economic feasibility. This study provides a foundation for future innovations, emphasizing the importance of intelligent, data-driven strategies in advancing global energy sustainability.

Abstract

This study aims to analyze the influence of Work Motivation and Work Environment on Employee Performance through Job Satisfaction as a mediating variable. The research employed a quantitative approach using a survey method involving 30 employees as respondents. A census sampling technique was applied, in which all members of the population were included as research respondents. Data were analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS) with the SmartPLS software. The measurement model evaluation demonstrated that all indicators satisfied the convergent validity criterion, with outer loading values exceeding 0.70. In addition, all constructs met the reliability requirements, with Cronbach's Alpha and Composite Reliability values greater than 0.70 and Average Variance Extracted (AVE) values above 0.50. The structural model results revealed that Work Motivation had a positive and significant effect on Job Satisfaction (β = 0.398), Work Environment positively and significantly influenced Job Satisfaction (β = 0.342), Work Motivation positively and significantly affected Employee Performance (β = 0.236), Work Environment positively and significantly affected Employee Performance (β = 0.287), and Job Satisfaction had the strongest positive and significant effect on Employee Performance (β = 0.401). Furthermore, Job Satisfaction was found to partially mediate the relationships between Work Motivation and Employee Performance, as well as between Work Environment and Employee Performance. The coefficient of determination indicated that the proposed model explained 52.1% of the variance in Job Satisfaction and 61.2% of the variance in Employee Performance. These findings suggest that improving employees' work motivation and creating a supportive work environment can enhance job satisfaction, which in turn contributes to better employee performance.
