... g consists of an alpha test and a beta test to determine the level of product feasibility and test the effectiveness of products on student learning outcomes. The instruments that used to collect data were observation sheet, interview guidelines, scoring questionnaires, and test. The data that have been collected were analysed by qualitative descriptive technique. The results of this study can be concluded: 1) Learning media is very good. 2) Learning material is very good. 3) The individual test result is very good. 4) The small group test result is very good. 5) The final product trial result is very good. The android-based chemistry learning media produced is worthy to be used and effectively used in upper class students and middle class students, but it is not yet effective to be used in lower class students.
