This study aims to determine the effectiveness of learning biology on the respiratory system material based on integrated multimedia character education at SMAN 2 Percut Sei Tuan TP 2021/2022. The sample used in this study was one class (40 people). This research is quantitative descriptive. The instruments used to collect data are multiple choice tests and questionnaires. The data collection method used in this study was observation, interviews, questionnaires and tests (multiple choice) as a result of student learning given a score. The percentage of students' learning completeness (80%) or 24 students are said to be complete because they get a score that exceeds the KKM limit and (20%) or 6 students are not complete because the student is not able to get a score above the KKM limit. Thus, it can be concluded that learning biology on the material of the multimedia-based respiratory system integrated character education at SMAN 2 Percut Sei Tuan TP 2021/2022 is quite effective.

Student Worksheet (LKPD) is one way to support and activate learning activities so that students and teachers can interact more effectively, which can improve learning activities and student achievement. Because PhET media encourages creativity, it can help students' creative thinking skills. 4D technique, PhET Simulation helps the development of LKPD. In this study, data collection used observational methods, questionnaires, tests, and documentation methods. In this study, descriptive analysis and N-gain test were used for data analysis. Two material experts, learning experts, design experts, seventh grade science teachers, and 32 seventh grade students of SMP N 2 Sunggal became the sample. Based on the approval of LKPD, learning experts, and learning materials experts and design experts, class VII science teachers and 32 students of class VII SMP N 2 Sunggu. Based on expert validation, learning experts and LKPD material design experts, the participant's response was very good and the LKPD materials assisted by PhET Simulation could improve students' creative thinking skills, which can be seen from the N-gain calculation, which is 0.71 high categories.
