As the ideological and philosophical basis of the Indonesian state, Pancasila plays an important role in the formation of national laws and regulations. This journal examines three main aspects of the function of Pancasila in law. First, Pancasila serves as a normative framework to ensure that laws are in accordance with basic values such as justice, humanity, and unity. Second, Pancasila strengthens legal legitimacy and political consensus in the midst of modern political dynamics that are often polarized. Third, there are problems in implementing Pancasila values in law, such as inconsistencies between positive laws and people's aspirations, as well as bureaucratic constraints. In addition, the journal discusses how the values of Pancasila should be instilled and taught, how it helps strengthen constitutional democracy, as well as its relationship to economic law, human rights, environmental issues, and international law. This journal emphasizes how important it is to apply the principles of Pancasila in facing global challenges and maintaining the integrity of the nation. The research method used in this article is a qualitative approach with document analysis and literature studies on laws, court decisions, and other legal sources. The results of the study show that the application of Pancasila in law in Indonesia still faces various challenges, but it has great potential to strengthen the national legal system, especially in the aspects of social justice and constitutional democracy.

The application of Pancasila as an ethical foundation in law enforcement against criminal acts of terrorism in Indonesia highlights the importance of integrating humanitarian values and human rights principles. This article analyses how Pancasila, with its focus on social justice and humane treatment, distinguishes Indonesia's approach from repressive methods commonly applied in other countries. The research method used in this article is a descriptive qualitative approach, which includes document analysis as well as in-depth interviews with various stakeholders, including law enforcement, academics, and deradicalisation practitioners. The data obtained is analysed to evaluate the effectiveness of deradicalisation programmes based on the principles of Pancasila and its impact on reducing radicalisation as well as reintegration of former terrorism perpetrators. By emphasising the need for a balanced policy between security and human rights, the Pancasila-based approach proved to be more effective and sustainable in the long run. Challenges in the consistent application of Pancasila values are faced in the context of globalisation and advances in information technology. The results show that this approach not only reduces radicalisation but also facilitates the reintegration of former terrorism perpetrators into society. In conclusion, the application of Pancasila in law enforcement contributes significantly to national stability and can be a model for other countries in countering global terrorism.

The role of Pancasila as a source of law within the adat (customary law) system in Indonesia involves analyzing its alignment and contemporary challenges. Pancasila, as the state ideology, serves as a fundamental guide for the formulation and application of laws throughout Indonesia. However, integrating Pancasila's values into the diverse adat legal systems presents significant challenges regarding both value alignment and practical application. This study uses qualitative analysis with a case study approach to evaluate how Pancasila’s principles are implemented in adat law and assess how well these values align with existing adat norms. Findings indicate that despite efforts to reconcile Pancasila with adat law, there are several obstacles, including differences in value interpretation, resistance from indigenous communities, and difficulties in harmonizing national and adat laws. The article concludes that a more dialogic and inclusive approach is needed to align Pancasila with adat law and recommends policy reforms and enhanced understanding of Pancasila's values at the local level to ensure fair and sustainable legal enforcement.
