ABSTRACT The use of media in teaching and learning can clarify students understanding of the subject matter and can make the learning process more interesting and effective . But the reality in the learning process , teachers are not using the medium of learning because teachers are not able to make instructional media and just rely on the book as a source of learning , thus making the students find it difficult to understand the material . Associated with it is developed interactive media on the material organization of life for SMP . This study aims to produce an interactive media organizations on the material of valid and practical life . This type of research is the development of research by using a 4 - D models which consists of 4 stages , namely , the definition (define) , design (design) , development (develop) and the spread (disseminate) , but the deployment phase (disseminate) is not done . Define phase consists of a curriculum analysis , analysis of students and media analysis . At the design stage to design interactive media . At this stage of develop test the validity and practicalities . Test validity by a validator which consists of 2 lecture of biology and 1 junior high school biology teacher . Test practicalities by 1 biology teacher and junior class VII Perti Padang . These data were analyzed with descriptive analysis . The results of the validity test of interactive media by validator shows that interactive media is in the valid criteria ie 86.25 % in terms of variable material / content, form of media , motivation , and language . Test results practicalities of interactive media by teachers indicate that interactive media is in a very practical criterion is 88.67 % and the test results demonstrate the practicalities of interactive media by students is located in a very practical criterion is 86.72 % in terms of practicality variable ease of use , availability time , the appeal of the device , interpreted the material , which is the same as the equivalent of teaching materials and evaluation. This suggests that interactive media on the material life of the resulting organization is valid and very practical .
