This study aims to improve students' learning outcomes in zakat learning through the Problem Based Learning (PBL) model. The method used is Classroom Action Research (CAR) with two cycles that include planning, implementation, observation, and reflection. The results of the study showed that the implementation of PBL improved students' understanding and participation. In cycle 1, learning motivation increased, but there were still students who were less active. Improvements in cycle 2, such as more intensive guidance and relevant case studies, showed a significant increase in students' understanding and involvement. In conclusion, PBL is effective in improving zakat learning outcomes, encouraging students to think critically, and understanding the concept of zakat in theory and practice.
