<![CDATA[ABSTRACT This research was motivated by the low learning outcomes of students in Indonesian language learning content, this was obtained from the results of the pre-test which was used as pre-cycle data. This research aims to determine the Indonesian language learning outcomes of class 3 students by applying the Problem Based Learning model using EDUDOMI media. The method used in this research is classroom action research carried out collaboratively based on lesson study. Data collection techniques in this research are observation, interviews, tests and documentation. This research was carried out in the pre-cycle, cycle I and cycle II stages. The implementation of cycles I and II is carried out based on lesson study with plan, do and see activities. The subjects of this research were 24 students in class 3B at SDN Lawang Gintung 2. The research results at the pre-cycle stage showed that the average percentage obtained was 49.16%, in cycle I the average learning outcome obtained was 76.25%, and in cycle II the average learning outcome obtained for cognitive aspects of students worth 93.33%. Based on the percentage obtained, this research, entitled Application of the Problem Based Learning Model with EDUDOMI Media to Improve Indonesian Language Learning Outcomes for Grade 3 Elementary School Students, was declared successful.
