The training program carried out at the Serang Class IIA Prison is still not in accordance with the word good. Because there are still several problems found, namely the limited means of learning infrastructure such as the lack of training tools, learning places that cause the learning process to be not optimal, teaching materials that are still lacking, and relatively short learning time, as well as the lack of tutors' understanding of adult education in delivering materials to learning residents. For this reason, this study aims to find out how the implementation of the training can improve the life skills of inmates in the Serang Class IIA Prison. This research uses a descriptive method through a qualitative approach. The results of the study showed that barbering training was able to improve the life skills of inmates, especially in psychomotor, cognitive, and affective aspects.
