Assessment of instructional media experts get a percentage of 71.25% (Feasible). 4) Implementation, trial use of the product to get a percentage of product eligibility to get a percentage value of 84% (Very Feasible) and produce test scores in the form of pre-test and post-test as follows: The results of the experimental class assessment, obtained the average total value of the electrical materials section in the pre-test 37 and post-test 70, while from the sub-section of the electric current circuit, the average value of the total pre-test is 40 and the post-test is 75. In the control class assessment results, obtained the average total value of the electrical materials section in the pre-test of 45 and post-test of 56, while from the direct current electric section subsection the total average value at the pre-test is 54 and the post-test is 68. Based on these results, the development of this study is very feasible to be used as a learning support media that provides a significant increase in value in the experimental class. \u0000ABSTRAK \u0000Penelitian dan pengembangan ini untuk mengetahui kelayakan media pembelajaran dan menghasilkan modul pembelajaran elektronik berbasis e-learning dengan aplikasi edmodo dalam mata Dasar Listrik dan Elektronika sebagai media penunjang pembelajaran.
