The purpose of this study is to produce android-based GES-Math learning media on the material of a two-variable linear equation system (TVLES) and to know the validity, effectiveness, and practicality of the learning media in increasing students' interest and motivation. This research includes research and mining (R&D). The development model used in this study is 4D (Four D Models) consisting of 4 stages of development, including: define, design, development, and disseminated. This android-based GES-Math learning medium was developed with the help of an articulate storyline application. The subject of this study is Gowa State Junior High School. The learning media trial was conducted twice, namely a small-scale trial followed by 6 students from grade VIII-2 and a largescale trial followed by all grade VIII-2. The instruments used in this study are media validation sheets by validators, study result tests, and student response questionnaires. Based on the validation results obtained an average of 4 (very valid). While the results of the analysis of the questionnaire response of students obtained an average result of 3.9 (very practical). Meanwhile, the intermediate test of study results obtained by 86 means that the resulting product is already eligible for use because it meets the criteria of validity, practicality, and effectiveness.
