The research examines how good corporate governance influences profitability among Indonesian oil and gas companies listed on IDX between 2019-2023. The study measures profitability through return on assets while assessing GCG via three components: Independent Board of Commissioners, Institutional Ownership, and Managerial Ownership. Using Eviews 12 software, researchers conducted panel data regression analysis on 9 companies across a five-year timeframe. The findings indicate that only Institutional Ownership significantly impacted profitability, while Independent Board of Commissioners and Managerial Ownership showed no meaningful effect on ROA. The research concluded that these GCG elements, when analyzed collectively, did not demonstrate substantial influence on profitability levels.
