<![CDATA[ABSTRACT Adolescence is a crucial transitional phase characterized by physical, cognitive, and psychosocial changes. Psychosocial issues, such as bullying, often trigger a decline in self-esteem, anxiety, and even depression among adolescents. This community service initiative aims to enhance the self-esteem and mental resilience of students at SMKN 39 Central Jakarta through an intervention involving the "Self-Strength Reflection Game." The implementation method comprises three main stages: (1) Preparation and Assessment, (2) Implementation, and (3) Evaluation and Follow-up Support. The results indicate an improvement in student understanding and awareness (with a 100% active participation rate) regarding recognizing emotions, identifying personal strengths, and transforming maladaptive behaviors into assertive ones. Furthermore, the initiative successfully produced a teaching module titled "Innovation for a Healthy, Bullying-Free School Family Resilience," a booklet, and reflection cards integrated with the school's School Health Unit (UKS). Keywords: Self-Strength Reflection, Self-Esteem, Adolescent Mental Health, Bullying, Healthy School.
