The Biology learning process in class XII IPA at SMA Negeri 1 Danau Panggang has so far been more dominant in applying conventional learning models which are characterized by 1) teacher-centered, 2) emphasis on receiving knowledge, 3) less variety, 4) less empowerment of all potential students, and 5) using a monotonous method, because the teacher is dominant as the center of learning resources as a result, there are still many students who are passive, most students do not dare to ask questions. Student activity in learning and discussion is still low, many students in the learning process seem to be passive. As a result, learning becomes boring and less passionate, so learning outcomes are low. The purpose of this study was to improve learning outcomes of Biology on the subject of enzymes and their functions through Modification of the Multiple Representation Learning Model in class XII IPA SMAN 1 Danau Panggang. The research method used is comparative descriptive. Data were taken from 23 students with details of 8 men and 15 women. Then from the data, the percentage value of student learning completeness classically is sought using a predetermined formula using instruments in the form of observations of teacher activities, observations of student activities and student learning outcomes. The results of the final study showed that the average value obtained was 76.52 and the completeness of learning outcomes was 100%. Meanwhile, the activities of teachers and students also increased. Teacher activity increased from 59.72% to 79% with criteria from good to very good. Student activity also increased from 48% to 65% with good criteria

Learning mathematics that tends to be monotonous will cause boredom and for students. This can be seen from their enthusiasm for learning. They pay attention when the teacher provides material and sample questions, but when working on the questions, they have difficulty. Therefore, it is necessary to think about ways of presenting and learning mathematics that are suitable for students, so that students can actively participate in the learning process. The suitable model is the cooperative model. One of the cooperative models is the STAD type. In this type, the teacher provides material, which in the next group of students will be deepened further. At the time of the teacher's presentation, students must really pay attention, so that later when doing quizzes they will not experience difficulties. In the group, all students can certainly master the material being studied. students of class X MIPA 1 in the even semester of the 2019/2020 Academic Year after participating in the learning process by applying the STAD type cooperative learning model. Methods of collecting data using the method of observation and tests. The technique used in this research is descriptive analytical technique, namely quantitative data obtained from quiz results that are processed using percentage descriptions and qualitative data obtained from observations about teacher and student activities are used as the basis for describing the successful application of the STAD type cooperative learning model. Student learning outcomes from cycle I and cycle II have increased. For the first cycle the average value is 54.17. While in the second cycle the average value is 67.92.
