The low learning outcomes of class XII students of industrial automation techniques in the subject of electropneumatic control systems are due to the fact that there are still many students who have difficulty understanding electropneumatics, lecture-oriented presentation of material causes students to be passive and bored because they tend to memorize concepts without knowing how the concept is formed. This causes students to not be able to learn independently. The purpose of this research is to develop teaching materials for electropneumatic control system learning e-modules in the industrial automation engineering department that have feasible, practical and effective criteria. This study uses research and development (R&D) methods with a 4D (four-D) development model. The results showed that the E-learning module was declared valid with a validity value of 0, 89 based on the validation of four material validators and in terms of media validity it was declared valid with a value of 0.88 from three validators. E-modules are stated to be very practical based on teacher and student responses. This shows that, E-modules are effectively used as one of the teaching materials in learning in improving student learning outcomes.
