Indonesia finally has its own Criminal Code; the country no longer uses the criminal code inherited from Dutch East Indies colonialism. Nonetheless, the New Criminal Code is effective three years after its launch, which is in 2026. By reviewing literature, this article explores the New Criminal Code and its link to relations to terrorism and terrorism financing laws. This article aims to understand how far terrorism is addressed in the Indonesian New Criminal Code. This article may help counter-terrorism practitioners, academics, and policymakers to employ legal instruments as much as possible to prevent terrorism. Regarding the preparation of terrorism, the New Criminal Code outwardly revises what is already listed in the Law no. 5/2018 where anyone who prepares acts of terrorism whether intentionally or unintentionally is eligible for criminalization. There have been several criticisms of the New Criminal Code, such as its overlapping with other laws, the contradiction of regulations stated in the New Criminal Code, and its low support on restorative justice for children affiliated with terrorist organizations.
