This study aims to develop interactive multimedia learning media on science subjects using Adobe Flash as a learning media for SD IVC classes. This development is in the form of learning media products in an interactive CD. The method used in this study uses the Research and Development (R & D) method with a 4D model that has 4 stages of development, namely define, design, development, and desseminate. The results of the validation test show that interactive multimedia learning media in science subjects are declared good with the results of validation by media experts 3.75 with very valid categories, expert material 3.5 with very valid categories, and by 3.54 users in good categories. Based on the N-Gain of 0.60 with the medium category and it can be said that the effectiveness of interactive multimedia as a learning media is classified as effective. Based on these results, it can be concluded that the development of interactive multimedia on science subjects using adobe flash as an instructional media for SD IVC is declared feasible and effective to be used in the learning and teaching process.

This study aims to improve the learning outcomes of elementary school science students by using interactive multimedia on human skeleton material. This interactive multimedia is a learning media product in the form of an interactive CD. Based on information obtained by researchers that the lack of enthusiasm of students in science subjects, because students do not have a real picture of how the material process is explained. Therefore, this media is very important to support the learning process of science. The method used in this study uses the Research and Development (R&D) method with the 4D model which has 4 stages of development namely define, design, development, and disseminate. The results of the use of interactive multimedia on students showed that the average pretest score was 57.33 while the average posttest score was 84.17. Based on N-Gain of 0.60 in the medium category and it can be said that the effectiveness of interactive multimedia as a learning medium is classified as effective. Based on these results, it can be concluded that there is an increase in science learning outcomes for students of SDN 034 Taraibangun class IV using interactive multimedia on human skeleton material.
