Abstract

Teaching materials are one of the important factors that influence the success or failure of learning. The learning resources used in SMA Negeri 15 Semarang are in the form of textbooks that do not contain the latest research results. There needs to be a complete and interesting teaching supplement so that learning about the digestive system material contains research results. This study aims to develop a digestive system teaching supplement that is suitable for use in learning and can improve students' understanding of concepts and self-awareness. The research design is Research & Development (R&D) with a 4D model, through the stages of define, design, develop, and disseminate. The define stage is used to make design and develop of teaching supplements. The teaching supplements that are developed are then tested for feasibility (expert validation, teacher responses, student responses) and their effectiveness in learning the digestive system. The subjects of this study were students of grades XI and XII of SMA Negeri 15 Semarang. The results of the study showed that the validity of the media and materials was in the very valid criteria. Teacher responses and student responses were in the very feasible criteria. The teaching supplements that were developed can also improve students' understanding of concepts with moderate criteria and the average self-awareness of students towards the dangers of obesity including very good criteria. It can be concluded that the developed digestive system teaching supplement is suitable for use in learning and can improve students' conceptual understanding and self-awareness of the dangers of obesity.
