In the era of globalization and increasing intensity of competition, public companies in Indonesia are required to develop internal strategies that are able to support sustainability and performance improvement in a sustainable manner. This study aims to analyze the relationship between leadership style, work discipline, and compliance with the principles of good corporate governance (GCG) in companies that are members of the LQ45 index on the Indonesia Stock Exchange. The method used is a normative qualitative approach with document study techniques, using secondary data in the form of annual reports, sustainability reports, and related academic literature. The results show that the application of transformational leadership styles, characterized by employee empowerment, innovation, and sustainable motivation, is significantly positively correlated with the implementation of a structured work discipline system and adherence to GCG principles. These findings confirm that the integration between effective leadership and organizational discipline is a strategic foundation in creating an adaptive, competitive, and integrity work culture. This research makes an important contribution to strengthening contemporary management theory and corporate governance practices, as well as becoming a reference for companies in building a superior internal management system.

This study explores the role of logical principles as a scientific foundation in economics, highlighting how logic supports theory development, empirical analysis, and decision-making in this discipline. As the foundation of scientific methodology, logic ensures consistency, validity, and coherence in research, helping to avoid cognitive biases and logical fallacies that often arise in economic analysis. Using the Systematic Literature Review (SLR) method, this study synthesizes findings from various academic sources to explain the importance of logical principles such as deduction, induction, and probability in building economic theories and addressing challenges in modern economic research. In conclusion, the proper application of logic not only improves the quality of research but also the credibility of the resulting economic policies.
