Development of teaching material in mathematics “Sapta Maino Education” on topics of plane geometry

This study aims to produce and develop learning media based on Android applications and Arduino microcontrollers which are named "Sapta Maino Education". The development of learning media based on Sapta Maino Education is done to be able to attract students motivation in learning, especially the material to build flat side spaces. In addition to that, learning can adjust technological developments and teachers are expected to be able to spur creativity in making learning media that follows the development of the era. This research uses research and development methods with the ADDIE development model. The data collection method uses an instrument in the form of a questionnaire. Validation involves two material experts and two media experts, then a trial run on students. The results of this study are in the form of learning media based on Sapta Maino Education consisting of Android and Arduino LED Cube applications. The results of the assessment of media experts got a percentage of 89.4%. Material experts 86.21%., And the percentage of respondents or students amounted to 89.4%. All three are included in the "very decent/very good" category. The results of the study have the disadvantage that the material is only limited to the material Cubes and Beams. Based on the results of the assessment by media experts, material experts and usage tests by respondents, it can be concluded that learning media based on Sapta Maino Education is very feasible to use.
