Efforts to Improve Students' Understanding in Mathematics Subjects to the Introduction to the Concept of the Smallest Multiple Partnership (KPK) Using Dakon Numbers Media

Learning mathematics on the subject of the Least Fellowship (KPK) is very important to be taught in elementary schools for reasons related to reality. Based on observations, this material is considered difficult because the method used by the teacher is still conventional and does not use learning media, from the results of an interview study conducted on 18 students only one student can answer it, therefore a new method is needed to overcome this problem. Researchers used dakon media on the grounds that in the learning process students were invited to be active in learning activities by being given a stimulus in the form of media. In accordance with the respondent's learning theory where learning is produced from experience with an environment in which there is a relationship between stimulus and response. The objectives of this study were: (1) to find out how to increase understanding of the KPK material, (2) to find out the students' interest in learning using Dakon media. This study used the PTK method which adopted the Kemmis a Taggart model which consisted of two cycles. Data collection was carried out through interviews, observation, filling out questionnaires and tests, analyzed by reflection in each cycle. The results showed a significant increase in both student understanding and student interest. Acquisition of student learning outcomes with an average in cycle I reached 70 with a percentage of 44% completeness, cycle II with an average of 92 and a percentage of completeness of 100%.n
