<![CDATA[This article presents learning media innovations in accordance with technological developments. The research problem is the difficulty of students understanding the human respiratory system material because the teacher uses the lecture method. In addition, there is no learning media to help students' concrete understanding. Learning media is needed to make it easier for students to understand the material. The research method used is Research & Development, ADDIE (Analysis, Design, Development, Implementation, and Evaluation). The purpose of this study was to determine the validity and effectiveness of SAC Application Assisted Human Respiratory System Material Learning Media for Elementary Schools. The subjects of this study were 17 fifth grade students at SDN Sumberagung 01, Jaken, Pati. The results of the validation of linguists were 100%, the validation of media experts was 97.5%, the validation of material experts was 98.5%, the validation of teachers (practitioners) was 98.9%. The N.Gain test is 0.90 and the percentage of student responses is 94.1%. The conclusion of this study is that Learning Media for Human Respiratory System Materials Assisted by the SAC Application for Elementary Schools is valid and effective for increasing learning outcomes in Natural Sciences subject matter for human respiratory systems in class V students.]]>
