The Influence of Organizational Culture, Leadership and Motivation on Human Resource Development with Continuous Improvement as a Moderating Variable at the Regional Secretariat Medan City

This study is motivated by the importance of human resource development in improving public organizational performance, particularly at the Regional Secretariat of Medan City, which still faces issues such as low employee motivation, suboptimal leadership, and inconsistent implementation of organizational culture. The objective of this study is to analyze the influence of organizational culture, leadership, and motivation on human resource development, with continuous improvement as a moderating variable. The research employs a quantitative approach using an associative method, with a saturated sample of 213 civil servants. Data were collected through questionnaires and analyzed using SEM-PLS with SmartPLS software. The results indicate that organizational culture, leadership, and motivation have a positive and significant effect on human resource development, with motivation as the most dominant variable. Furthermore, continuous improvement significantly strengthens the relationship between independent and dependent variables. The R-square value of 0.968 indicates a strong explanatory power of the model. The study concludes that enhancing organizational culture, leadership quality, and work motivation, supported by systematic continuous improvement, can effectively optimize human resource development.
