The objective of this study is to develop Interactive Multimedia to overcome the difficulty faced by students in problem-solving skills and calculation in the Engineering Materials course, specifically on Isomorphous Binary Phase Diagrams. The Interactive Multimedia was developed using the Design-Based Research approach and used as learning media during the Engineering Materials course’s learning process. Based on preliminary research on Engineering Material course learning, 63% of students faced difficulties in learning the Phase Diagrams subject. In general, 50% had difficulties in the mastery and calculation contained in the Phase Diagrams subject. This is because the Engineering Materials course has a characteristic of abstract, complex, and dynamic concepts. The study used an experimental method with the One Group Pre-test and Post-test design. The participants in the study as a research subject were 44 students from Mechanical Engineering. The results of the study showed that Interactive Multimedia is capable to overcome the difficulties of students' in the Isomorphous Binary Phase Diagram subject. It is because interactive multimedia can attract the attention of students in the lesson material delivery, thereby increasing their interest in learning this material. It also showed that the difficulties can be overcome by the implementation of Interactive Multimedia during the learning process.
