This study uses a qualitative method with a descriptive approach. Data collection techniques are carried out through observation, interviews, and documentation with research subjects including Pancasila Education teachers, vice principals for student affairs, and 20 class XI students of SMA N 1 Sukoharjo. The results of the study indicate that the implementation of Pancasila values is carried out through the instillation of humanity, unity and cooperation, habituation of attitude reflection, and learning related to bullying problems in everyday life. In addition, there are anti-bullying preventive efforts carried out by teachers such as instilling moral and character values, providing anti-bullying socialization to students, and teachers as role models for students. The obstacles found include teachers' understanding that still needs strengthening in implementing Pancasila values, learning strategies that have not fully involved all students actively, limited effectiveness of learning resources in dealing with the development of social media, low social involvement of some students, school environmental conditions that are still influenced by bullying behavior, support for school policies that need to be consistently strengthened, and the influence of factors outside the school such as social interactions and social media.]]>
