Illegal electricity tampering remains a serious issue in the electricity sector as it causes losses to PT PLN, disrupts the stability of the electricity distribution system, and endangers public safety. This research aims to examine the mechanisms for resolving cases of illegal electricity connections and the implementation of law enforcement against offenders at PT PLN UP3 Banda Aceh. This research uses an empirical legal method with a sociological-juridical approach. Data were obtained through interviews, observations, documentation studies, and literature reviews, which were then analyzed descriptively and qualitatively. The research results show that the resolution of electricity current addition cases is carried out through administrative and criminal mechanisms. Administrative resolution begins with an inspection by the Electricity Usage Regulation Officers (P2TL) to identify violations of electricity usage. Violations are classified into P1 (power limit violations), P2 (manipulation of electrical measuring devices), P3 (a combination of P1 and P2), and P4 (illegal use of electricity by non-PLN customers). For P1, P2, and P3 violations, PLN imposes administrative sanctions in the form of follow-up bills, compensation payments, temporary disconnection of electricity, and dismantling of installations. Meanwhile, violations that meet the elements of a criminal offense based on Law Number 30 of 2009 concerning electricity, specifically P4 violations or those causing significant losses and disrupting the electricity network, are resolved through the criminal justice process. This study concludes that administrative resolution is more dominantly applied, while criminal law enforcement is used for serious violations to achieve legal certainty, recovery of losses, orderly use of electrical power, and a deterrent effect on the perpetrators.
