This activity was motivated by the phenomenon of violence in schools, both by students and by teachers. Symptoms of bullying behaviors such as verbal, physical, social, and cyberbullying can be found in junior and senior high schools in Purwokerto, Indonesia. This Participatory Action Research aims to establish preventive and intervention programs against student bullying. Before empowering students and teachers, it begins with mapping the problem of bullying, building relationships with stakeholders, planning preventive and curative actions. Community change is accomplished through workshops on bullying prevention and treatments, the formation of anti-bullying agents, and focus group discussions. The results of this activity are shown by the increase in knowledge of bullying in students, the construction of anti-bullying agents, preventive actions in the form of anti-bullying campaigns with poster media, the preparation of standard operating procedures for bullying intervention programs.
