Many studies show the effectiveness of using the Flipped Learning model to increase students' understanding. However, there are scant research results that integrate PowerPoint in Flipped Learning to improve students' understanding. The present study aimed to describe the effectiveness of the PowerPoint-Based Flipped Learning model in increasing students' understanding. The recent study is an experimental study with 115 participants divided into a class with a PBFL model, a class with a Flipped Learning model, and a class with a conventional model. The sampling technique used was random cluster sampling, and the data collection was collected through documentation and test method. By using the One-Way ANOVA test, it was found that there was a difference in the mean between the three classes with a significant difference below 0.05. Therefore, a post-hoc test was carried out using the Scheeffe test. The results showed that integrating PowerPoint in the Flipped Learning model significantly increased students' understanding of the material being taught compared to the other classes. All in all, integrating PowerPoint is shown to help strengthen the Flipped Learning-based learning process to improve students' understanding. In addition, this research can still be expanded by broadening the range of research subjects.
