This study aims to improve the motivation to learn the Al-Qur'an Surah At-Tin in grade V students of SD Negeri 091601 Dolok Merangir through the application of the Cooperative Learning learning model. This model is considered capable of creating an interactive and collaborative learning environment, so that students can learn more enthusiastically and meaningfully. The research method used is Classroom Action Research (CAR) which is carried out in two cycles. Each cycle includes the stages of planning, implementation, observation, and reflection. The results of the study showed that the application of Cooperative Learning had a positive impact on students' learning motivation. In the first cycle, although there were several obstacles such as students' lack of initial understanding of group assignments, the results of observations showed an increase in student participation in group discussions. The second cycle succeeded in overcoming these obstacles by providing more detailed guidance to students, so that they were more confident and actively involved in learning. The increase in students' learning motivation can be seen from several indicators, including increased student activity in asking questions, discussing, and completing assignments in groups. In addition, students showed a more positive attitude towards learning the Al-Qur'an Surah At-Tin, marked by their increased attendance and interest in participating in the learning process. This study also found that Cooperative Learning provides space for students to help each other and work together, so that they can understand the material better. This approach helps students feel valued and more confident in expressing their opinions. The collaborative process that is established increases students' sense of responsibility for learning and supports the development of their social skills. Data analysis from the learning motivation questionnaire showed a significant increase between the first and second cycles. The average value of student motivation in the first cycle reached 65%, while in the second cycle it increased to 85%. This shows that the Cooperative Learning model effectively encourages student involvement in learning the Al-Qur'an Surat At-Tin. From the results of the study, it can be concluded that the application of the Cooperative Learning model can significantly increase student learning motivation. In addition, this model can be an effective alternative in creating an active, interactive, and enjoyable learning process. Therefore, teachers are advised to consider using Cooperative Learning in learning, especially for subjects that require in-depth understanding such as the Al-Qur'an Surat At-Tin
