Abstract

This study aims to analyze the influence of leadership, organizational culture, and motivation on employee performance, both partially and simultaneously, at PT. XYZ, an automotive component manufacturing company in Indonesia. This study employed a quantitative approach with a survey method involving 133 respondents selected through proportional random sampling. Data analysis was performed using multiple linear regression, preceded by validity and reliability tests, and classical assumption tests. The results showed that the three independent variables— leadership, organizational culture, and motivation—have a positive and significant effect on employee performance, both partially and simultaneously. This study contributes to the development of human resource management theory and provides practical implications for increasing productivity through leadership strategies, work culture, and motivation.
