Abstract

This study aims to determine the effect of competence and work motivation on employee performance at PT PAL Indonesia. The research method used is a quantitative approach with a sample of 92 employees selected through proportional stratified random sampling. Data analysis techniques employ multiple linear regression with t-test and F-test for hypothesis testing. The results show that competence and work motivation have a positive and significant effect on employee performance, both partially and simultaneously. The coefficient of determination (R²) value of 54.3% indicates that competence and work motivation contribute significantly to improving employee performance, while the remaining percentage is influenced by other factors. These findings emphasize the importance of competence development and motivation improvement to support optimal employee performance.

Abstract

This study aims to analyze the influence of celebrity endorsers, electronic word of mouth (e-WOM), and lifestyle on purchasing decisions for Eiger Adventure products. A quantitative approach was employed with data collected through questionnaires distributed to consumers who have purchased Eiger products. Multiple linear regression analysis was used to examine the effect of each variable. The findings show that simultaneously, celebrity endorsers, e-WOM, and lifestyle significantly influence purchasing decisions. However, partially, only celebrity endorsers and e-WOM have significant effects, while lifestyle does not. These findings highlight that promotional efforts through public figures and consumer reviews in digital media contribute more strongly to purchasing decisions than lifestyle factors. Therefore, companies are advised to maximize the role of endorsers and e-WOM strategies.
