<![CDATA[The implementation of regional autonomy in Indonesia is one form of implementation of the principle of decentralization that aims to increase the effectiveness of government administration, accelerate regional development, and realize public services that are more responsive to community needs. This study aims to analyze the implementation of regional autonomy from the perspective of Indonesian national law by focusing on the concept and legal basis of regional autonomy, its implementation in the national legal system, as well as the challenges and efforts to strengthen it. The research method used is normative legal research with a statutory and conceptual approach. The data used are primary, secondary, and tertiary legal materials analyzed qualitatively through literature studies. The results of the study indicate that regional autonomy has a strong constitutional basis in the 1945 Constitution of the Republic of Indonesia, specifically Article 18 and its regulations in laws and regulations governing regional government. From a national legal perspective, the granting of authority to regional governments is a form of decentralization that remains within the framework of the Unitary State of the Republic of Indonesia so that its implementation must be in line with the principles of legality, accountability, legal certainty, and national interests. The implementation of regional autonomy has provided space for local governments to develop policy innovations and improve the quality of public services, but still faces various obstacles such as institutional capacity imbalances, overlapping regulations, limited human resources, and suboptimal coordination between the central and regional governments. This study also found that strengthening the implementation of regional autonomy requires regulatory harmonization, increased capacity of government officials, effective oversight, transparent regional financial governance, and strengthened community participation in the policy-making process. Thus, the implementation of regional autonomy is not only an instrument of administrative decentralization, but also a legal mechanism that plays a vital role in realizing a democratic, efficient, and welfare-oriented government without neglecting the principle of unity and integrity in the Indonesian national legal system. ]]>
