Objective: This study aims to re-actualize Pancasila as a state ideology, especially the 3rd principle, namely Indonesian Unity. The meaning of unity is considered to be fading given the existence of Aceh, which in the past eighteen years has seen its status degraded, both explicitly and implicitly, especially about Aceh's authority as a special autonomous region.
Theoretical framework: this study compares constitutional theory through the text and context of Article 18B paragraph (1) of the 1945 Constitution and the Amendment Results. Next is the concept of asymmetric decentralization through Law Number 11 of 2006 concerning the Aceh Government (UUPA).
Method: The study used normative legal studies, where data collection is carried out using library research with a focus on the application of norms in the UUPA. Presented in a descriptive-analytical manner, by examining the implementation of UUPA based on juridical, historical, political, and social aspects, to find the concrete reality of the implementation of special autonomy in Aceh currently, and its projections in the future.
Results and Conclusions: The study shows that in the early days of Aceh's special autonomy, relations with the Central Government were constructive. Aceh has become the center of national mainstreaming. However, recently, conditions no longer work that way. The existence of the UUPA as a document for Aceh's development after the earthquake-tsunami and armed conflict is no longer a special concern for Jakarta, and this threatens the sense of unity of this country.
