Corporate governance has become an important issue in business activities from time to time. Especially in 1997, a monetary crisis occurred in Asian countries, including Indonesia, which was caused by weak corporate governance practices. Corporate governance has evolved towards various corporate failures as a result of poor corporate governance. Corporate governance is an effort to make Good Corporate Governance the rules and guidelines for company management in managing company management. Article 5 of the Law on State-Owned Enterprises (SOEs) states that SOEs are required to implement GCG in their companies, PT. Garuda Indonesia (Persero) Tbk (GIAA) as a national airline owned by the Government of Indonesia (SOE). SOEs are required to apply GCG consistently and sustainably based on the Ministerial Regulation while still observing the provisions, norms that apply and the articles of association of SOEs. However, a state-owned airline, namely GIAA, is suspected of being trapped by GCG violations when publishing the 2018 financial year report that has been published. This shows that in this case SOEs have not obeyed the rules and the application of GCG in SOEs has not been able to handle cases of losses suffered by SOEs so far. Starting from here it can be seen that SOEs financial management has not been carried out effectively and efficiently. With the implementation of GCG, SOEs should be able to manage their business and company performance well. The purpose of this study is to analyze the application of the principles of transparency and accountability in Good Corporate Governance in connection with the submission of PT Garuda Indonesia Tbk's financial statements in 2018 by using the juridical normative approach with descriptive methods, more specifically the legal approach and conceptual approach. The results of this study indicate that the principles of transparency and accountability in GCG are not implemented in the case of PT. Garuda Indonesia Tbk based on a review of the Limited Liability Company Law, the SOEs Law, the Capital Market Law.
