Forming students' character through education is an essential process in enhancing human dignity. One significant approach is through extracurricular activities, which not only develop students' potential, interests and talents, but also form attitudes of discipline, responsibility and self-confidence. This research aims to understand the role of extracurricular activities in forming the character of class VII students at SMP N 20 Surakarta. The research method used is descriptive qualitative with a case study approach, involving interviews, observation and documentation. The research results show that student involvement in extracurricular activities improves social skills, interests, talents, and creates positive habits such as cooperation, conflict management, and mature personality development. However, there are challenges in implementation, such as the lack of support for facilities and policies from schools. Therefore, a more effective and relevant extracurricular management strategy is needed to maximize its impact on students' character education.

In initial observations at SMP Negeri 20 Surakarta, various emotional and behavioral problems were found among students, including self-injurious behavior due to emotional stress, such as friendship conflicts and social pressure. This phenomenon highlights the importance of psychosocial interventions to increase awareness of mental health among adolescents. Adolescence, as a critical period of biological, psychological and social development, is vulnerable to internal and external conflicts that can affect mental well-being. Data shows that the prevalence of emotional mental disorders in adolescents is increasing, with risk factors including academic pressure, poor interpersonal relationships, and lack of mental health awareness and support. To overcome this, community service activities in the form of mental health psychoeducation were carried out at SMP Negeri 20 Surakarta. This activity includes training in managing emotions, strengthening interpersonal relationships, and increasing student awareness about the importance of mental health. Results show increased student understanding and awareness, as well as positive impacts on psychological well-being, social skills, and academic achievement. It is hoped that this program will be the first step in supporting adolescent mental health and reducing the risk of psychological disorders in the future.
