Education plays a crucial role in instilling the values of national integration from an early age. Elementary school (SD) as the first formal education level has a great responsibility in shaping the character of students who have a deep understanding of national identity, tolerance, and respect for differences. Using a qualitative approach, this research aims to explore in depth how Pancasila Education plays a role in shaping the character of national integration in students of SD No. 1 Pangsan and how this character building contributes to preventing acts of violence in the school environment. Based on the results of interviews and observations with principals, teachers, committees and students, the results show that students at SD No. 1 Pangsan have been able to internalize the values of Pancasila and national integration in an effort to prevent violence in the school environment. The implementation of strengthening the character of national integrity through Pancasila Education at SD No. 1 Pangsan comprehensively for students is to have a better understanding of the importance of unity, tolerance, and respect for differences. They will also be more aware of the negative impacts of violence and have the skills to prevent and resolve conflicts peacefully. The internalization of Pancasila values will be reflected in students' daily attitudes and behaviours, such as respecting each other, helping friends, avoiding bullying, and participating in school activities. The recommendations for optimizing the formation of national integration character through Pancasila education in an effort to prevent acts of violence at SD No. 1 Pangsan are the active role of teachers to improve competence through training, create a conducive school atmosphere, and involve the role of parents and the community in shaping student character.
