low activity and student learning outcomes in a class are influenced by several factors, one of which is because the behavior and learning models used by the teacher are not yet correct in implementing a learning process. These problems can affect the activity and completeness of student learning outcomes, so there needs to be special instruments that make them more active, especially on the subject of biology which contains many scientific names such as on the subject of Plantae. The purpose of this study was to determine the collaboration of three discussion instruments with the task of learning media products in the form of power points to increase student activity and student learning outcomes of class X MIPA-1 on the subject of Plantae. This research method uses comparative descriptive analysis with a qualitative approach using simple formulas in the form of calculating averages and percentages. The results of this study indicate that the class average score is 83.64 with the completeness of learning outcomes 90.91% with this value the completeness criteria can be categorized as achieved with student activity increasing from 73.21% to 96.63% with the criteria categorized as very good

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
