Test the Effectiveness of Mathematics Learning Media Based on Powtoon Animation Video in Junior High School on Two-Variable Linear Equation System Material

At this time, many students think that learning mathematics is difficult to understand. While Powtoon animation video-based mathematics learning media is still rarely applied, students feel bored. They do not understand the concept of material when the learning process uses the lecture method. The purpose of this study was to determine the effectiveness of using Powtoon animation video-based mathematics learning media on the material for the Two-Variable Linear Equation System in Junior High School. The type of approach used is a pre-experimental quantitative approach by applying a one-group pretest-posttest design. The research population includes all students of class VII-A at SMP NEGERI 1 NGIMBANG for the academic year 2020/2021, with 32 students consisting of 8 male students and 24 female students. Data collection techniques using tests and questionnaire sheets. While the data analysis technique used is normalized gain. The data obtained show differences in students' test results using the Powtoon animated video and before using the Powtoon animated video. The difference was seen from the average score of the students' test results before using the media of 36.41 and after using the media of 92.58. In addition, the research results from the N-Gain Test results show that the use of Powtoon animation video media is effective in learning mathematics. It is evidenced-based on the results of the expert test and media validation by obtaining 85% and 83.75%, which means that it belongs to the outstanding category. In comparison, the results of the student response questionnaire of 81.29% belong to the outstanding category. Students' test results get an average of 0.88% from the n-gain, which shows a high classification. This study indicates that Powtoon animation video media is effective in learning mathematics compared to learning that only uses the lecture method. 29% of it belongs to the outstanding category, then through the test results, students get an average of 0.88%, which is obtained from the n-gain, which means it shows a high classification.
