ABSTRACT Disasters caused by the eruption of Mount Semeru not only cause physical damage but also affect the mental condition of the victims, especially teenagers as one of the vulnerable groups who are going through psychosocial development in their lives. Teenagers after a disaster can experience anxiety, stress, depression, and even PTSD. This community service aims to improve stress management skills, rebuild a sense of safety, and enhance social connections within the community. This community service applied a psychosocial intervention method to improve knowledge, stress management skills, and peer support using growth focus resilience questionsare. From the analysis of measurement results from 19 respondents who underwent psychosocial interventions, there was a tendency for their psychological conditions to improve. This is evidenced by the average score increasing from 66.11 to 75.00 out of a maximum score of 80, indicating the potential of REM-JIWA in enhancing the adaptive ability and psychological resilience of post-disaster adolescents. Psychosocial interventions can reduce stress levels in teenagers and improve their knowledge of stress management and resilience in adolescents.
