Abstract

The crime of premeditated murder is a serious crime in the criminal law system regulated in Article 340 of the Criminal Code, with the element of “with premeditation” as the main differentiator from ordinary murder. This research examines the application of Article 340 of the Criminal Code in a murder case that occurred in Wonogiri in 2025, where the perpetrator allegedly killed his affair lover and made efforts to systematically disappear. The method used is normative juridical with statutory, conceptual, and case approaches, as well as descriptive-analytical qualitative analysis of primary, secondary, and tertiary legal materials. The results showed that proving the element of planning in Article 340 of the Criminal Code does not only refer to the intention of the perpetrator, but also to the existence of a time lag and a series of careful preparations, such as choosing a quiet place, removing traces by wrapping the body and casting the burial location. These actions indicate that the perpetrator had full control and awareness, so that this murder did not occur spontaneously or due to momentary emotional impulses. The complex motive of the affair strengthens the suspicion of a long-standing conflict that triggered the planning of the crime. Thus, the application of Article 340 of the Criminal Code against the perpetrators in this case is juridically and sociologically appropriate, providing a deterrent effect and maintaining the integrity of the criminal justice system in Indonesia. Proportional law enforcement against the crime of premeditated murder is important to uphold justice for victims and society.
