This research examines the effectiveness of using audiovisual media in teaching human anatomy at school level. The literature review was carried out by analyzing various trusted sources, such as scientific journals, books and online articles. The research results showed that the application of audiovisual media was proven to increase students' understanding and learning achievement in human anatomy subjects. The most effective audiovisual media are animated videos, 3D anatomical images, and interactive simulations. Appropriate use of audiovisual media helps students understand the structure and function of the human body better. Conclusion: Audiovisual media is an effective learning strategy to improve students' understanding and learning achievement in human anatomy subjects. Teachers need to use appropriate and varied audiovisual media in learning human anatomy to achieve optimal learning outcomes

This study aims to determine the effect of fermentation duration on the bioethanol yield and to determine the optimal fermentation time using Saccharomyces cerevisiae yeast. The research method involved several main stages: preparation of banana peel samples, acid hydrolysis (using H₂SO₄) to convert polysaccharides into glucose, and anaerobic fermentation. The fermentation times used in this study were 3, 5, 7, and 9 days with a constant concentration of Saccharomyces cerevisiae inoculum. The bioethanol content was measured using a distillation method followed by alcohol content measurement using an alcohol meter or gas chromatography (GC). The results showed that fermentation time had a significant effect on the bioethanol yield. The bioethanol content increased until it reached an optimal point on the 5th day (or adjust according to your data) with a content of ...%, and tended to decrease at longer fermentation times due to the depletion of nutrients in the medium and the accumulation of by-products that inhibited yeast growth. Based on these results, it can be concluded that banana peel waste is effective for use as a bioethanol substrate with an optimal fermentation time of 5 days.
