<![CDATA[This study was motivated by the importance of positive character building in elementary school students for community development, but initial observations in grade 4 of Muhammadiyah Gilipanda Elementary School, Bima City showed that many students (8 out of 24) still showed negative characters such as lack of discipline and responsibility. This study aims to determine the effectiveness of implementing the social collaboration model in building positive character in students, as well as identifying obstacles faced by teachers. The focus of the problem is how the implementation of a social collaboration-based learning model can shape positive character and what obstacles are faced by teachers. This study used a descriptive qualitative approach for one month at Muhammadiyah Gilipanda Elementary School, with data collection techniques through observation, interviews, and documentation. The results showed that before the implementation of the model, most students lacked a sense of responsibility. The implementation of the social collaboration model, which involves group learning, parental and community involvement, and discussion forums to train cooperation, has been proven to be used to build positive character. It was concluded that the social collaboration model is effective in improving social skills, fostering positive characters such as cooperation and respecting differences, and has the potential to improve students' academic achievement.
