Abstract

This study aims to analyze how the quality of training programs, organizational support, and innovative culture contribute to improving the competence of trainees at BPTT Darman Prasetyo PT Kereta Api Indonesia (Persero). A quantitative approach was used, involving 97 respondents as research samples. The research instruments were first evaluated through validity and reliability tests to ensure the accuracy and consistency of the measurements. The next stage included a series of classical tests for normality, multicollinearity, and heteroscedasticity to ensure that the analysis model met the relevant statistical requirements. After all analyses were completed, linear multiple regression was applied to identify and measure the contribution of each variable to the improvement of participants' competencies. The results of the analysis show that organizational support has a positive and significant effect on strengthening competency. The quality of the training program and innovative culture also show a positive effect, but have not yet reached a level of significance in terms of competency. The findings of this study confirm that adequate organizational support is a dominant element in encouraging an increase in the competency of training participants.

Abstract

This study aims to analyze the effects of workload and job stress on the performance of ShopeeFood drivers through work motivation as a mediating variable in Yogyakarta. The study employed a quantitative approach, involving 120 ShopeeFood drivers as respondents selected using purposive sampling. Data analysis was conducted using Partial Least Squares-Structural Equation Modeling (PLS-SEM). The results show that workload has a positive and significant effect on work motivation and driver performance. Conversely, job stress has a negative and significant effect on work motivation but does not have a significant direct effect on performance. Work motivation was found to have a positive and significant effect on performance and to mediate the effects of both workload and work stress on performance. The research model also demonstrated good predictive power, with an R-squared value for performance of 0.844. These findings confirm that work motivation is a key factor in improving the performance of ShopeeFood drivers; therefore, the company needs to strengthen strategies that can maintain and enhance the work motivation of its driver partners
