This study aims to identify conflict management strategies in building a harmonious school environment. The subjects of the study consisted of all teachers and students involved in inter-student conflict behavior in the 2023/2024 academic year, with samples taken from one class teacher. The research method used was qualitative, with data collected through observation, interviews, and documentation, as well as data analysis conducted descriptively qualitatively. The results of the study indicate that the role of teachers at SD Negeri 52 Banda Aceh is very effective in preventing and handling conflicts between students. The research process began with observation and discussion with the classroom teacher about the method to be used, followed by data collection carried out through observation, interviews, and documentation on October 12, 2024. Teachers apply various strategies, such as teaching positive values, implementing strict class rules, and running anti-conflict programs. Teachers' proactive response in handling conflict cases includes direct intervention, providing counseling, and involving parents. Although these efforts have a positive impact on students, challenges such as lack of special training, limited time, and lack of support from parents hinder the effectiveness of conflict management. Types of conflicts identified among students include verbal, psychological, and physical contact conflicts.
