This study aims to: 1) develop learning device through problem-based learning model with adobe flash are valid, practice, and effective; 2) analyze the combinatoric ability students in class XI of MAN 2 Deli Serdang through learning device developed by problem-based learning model with adobe flash. The type of This research is development research using the development model of the Thiagarajan 4-D model. Based on the results of trial I and trial II that have met valid criteria according to experts, were tested in class XI-MIA of MAN 2 Deli Serdang. The results of the analysis of the data obtained indicate that learning device based on PBL-AAF met the criteria of practice from the implementation of the learning device can be said good, effectiveness and can improve combinatoric ability.
