The influence of leadership style, work environment and competency on employee performance: job satisfaction as an intervening variable at the Labour and Transmigration Office in the Province of Riau Islands
Purpose: This study aimed to analyze the effect of Leadership Style, Work Environment, and Competence on Employee Performance through Job Satisfaction as an intervening variable at the Riau Islands Provincial Manpower and Transmigration Office, totaling 105 employees of the Riau Islands Provincial Manpower and Transmigration Office.
Methodology: The research method uses a quantitative approach with partial least squares (PLS) analysis techniques using SmartPLS version 4.0.
Results: The results show that Leadership Style and Work Environment have a positive but insignificant effect on Employee Performance, while Competence and Job Satisfaction have a positive and significant effect. Furthermore, Leadership Style, Work Environment, and Competence have a positive and significant effect on Job Satisfaction. Job Satisfaction does not mediate the effect of Leadership Style on Performance, but it does mediate the effects of Work Environment and Competence on Employee Performance.
Conclusions: Competence is a direct driver of employee performance, whereas Leadership Style and Work Environment exert their influence indirectly through Job Satisfaction. Enhancing job satisfaction can significantly improve performance.
Limitations: This study was limited to one government office in a specific province, which may affect the generalizability of the findings. The use of self-reported data may also introduce biases.
Contribution: This study contributes to the public sector human resource development literature by identifying key factors that influence employee performance and highlighting the mediating role of job satisfaction.

SintaConservation of palm wine using ultraviolet radiation
Purpose: This study aimed to explore the effectiveness of ultraviolet (UV) radiation in the conservation of palm wine by reducing its microbial load, specifically mold, yeast, and bacteria.
Research Methodology: Palm wine was conserved by sterilization with ultraviolet rays. The time of contact of the rays and the intensity of the rays with palm wine were varied. The microorganisms considered include molds, yeasts, and bacteria.
Results: The results showed that the microbial load of sterilized palm wine decreased with time of contact with the rays. The microbial load of the wine before and after sterilization was determined. Moreover, the microbial load further decreased during the storage of the sterilized samples. In fact, sterilization time of 240 seconds (4 minutes) reduced the mould and yeast from to and then to zero after 10 days of preservation.
Conclusions: UV radiation is an effective method for reducing microbial contamination in palm wine, with an optimal sterilization time of 240 s providing the best results. This sterilization process not only reduced microbial presence immediately but also extended the shelf life of palm wine during storage.
Limitations: This study did not examine the impact of stirring palm wine during sterilization on microbial load reduction, which could potentially influence the treatment’s effectiveness.
Contribution: This study established an ideal sterilization time of 240 s (4 min) for palm wine, providing an effective method for its preservation and ensuring its safety for consumption.
