This research examines the implementation of the proportionality principle in the
diversion process for child abuse cases involving both child perpetrators and
victims at the investigation level in Polresta Sleman. Utilizing a normative legal
research method with a juridical-normative approach, the study analyzes secondary
and primary legal materials, including legislation and literature, complemented by
interviews with investigators. The research reveals that while the diversion process
aligns with Law Number 11 of 2012 on Juvenile Criminal Justice System, significant
challenges persist in its practical implementation. Factors impeding successful
diversion include conflicts between perpetrators and victims, compensation
disputes, and investigators' limited capacities. The findings demonstrate that
despite comprehensive legal frameworks protecting children's rights, the actual
implementation of diversion remains suboptimal. Key obstacles include differing
interests between parties, inadequate negotiation mechanisms, and insufficient
understanding of proportionality principles. The study concludes that systematic
efforts are necessary to enhance investigators' skills, develop more holistic conflict
resolution approaches, and ensure the best interests of children are consistently
prioritized within the juvenile justice system, ultimately recommending more
nuanced and child-centered strategies for addressing juvenile offenses.
