ABSTRACT This study examines efforts to combat terrorism in Indonesia from a criminal law perspective. Terrorism is a crime with special characteristics because it not only attacks individual victims but also threatens the sense of security of the community, public order, state stability, and humanitarian values. This study uses a normative legal research method with a statutory and conceptual approach. The main legal materials used include Law Number 5 of 2018, Law Number 15 of 2003, Government Regulation Number 77 of 2019, Presidential Regulation Number 7 of 2021, and BNPT Regulation Number 1 of 2025. The results show that countering terrorism in Indonesian criminal law is carried out through two approaches: penal and non-penal policies. Penal policies are implemented through the criminalization of acts of terrorism, the expansion of criminal liability for perpetrators, networks, financiers, organizations, and corporations, and the implementation of special criminal procedural law. Meanwhile, non-penal policies are implemented through national preparedness, counter-radicalization, deradicalization, victim protection, protection of law enforcement officers, and cross-agency coordination. This research confirms that criminal law in terrorism cases functions as a means of protecting society and, to some extent, acts as a primum remedium. However, its use must remain constrained by the principles of legality, proportionality, human rights protection, prudence, and due process of law. Therefore, the ideal counterterrorism approach is an integrated criminal policy model that combines the firmness of criminal law with humane, measurable, and rule-of-law social deterrence.
