This research aims to find out how law enforcement is carried out against perpetrators of recidivist criminal acts of theft. The research method used is juridical-normative which is analyzed qualitatively. The research results show that recidivism is the repetition of a criminal act by the same perpetrator, where the criminal act committed previously has been sentenced to a criminal sentence and has permanent legal force, and the repetition occurs within a certain period of time. When imposing a sentence, the judge does not mention the amount of additional prison sentence of 1/3 (one third) of the main criminal threat (the presence of a criminal aggravation due to recidivism reasons), because the judge will basically immediately impose a long sentence on the defendant. Crime prevention is a variety of proactive and reactive activities directed at perpetrators and victims, and in the social and physical environment, carried out before and after a crime occurs. There are two ways of dealing with recidivist crimes, namely, preventive and repressive.
