The pandemic has become a concern in the field of education, which has made the conventional learning system switch to online; this means that educators innovate to create innovative teaching materials that access online and offline. The research objectives were to aim for (1) The improvement of student learning outcomes after being taught e-modules; (2) Student learning outcomes that met the minimum competency standards; (3) Student responses to e-modules. This study used test instruments and student response questionnaires. The research sample was 31 students of UNIMED chemistry education class 2020. The results showed an increase in student learning outcomes that achieved the high N-gain criteria of 0.74 and met the minimum competency standard, namely 80, and student responses were 89.04% in the excellent category, so the innovative KKNI-based e-module on oxygen and sulfur materials can be used as a reference for learning resources.

This study aimed to determine the needs of learning media in schools, the feasibility of the media created following the National Education Standards Agency (BSNP) criteria, and the effectiveness of the learning media on student learning outcomes. This research employed the ADDIE method (Analysis, Development, Design, Implementation, and Evaluation) involving 30 class X (tenth-grade) students. According to the analysis results of the Lectora Inspire media, the mean score of the content feasibility aspects was 3.88 (highly feasible), and the mean score of the presentation feasibility aspects was 3.89 (highly feasible). Furthermore, the developed media was implemented in the teaching and learning process to determine its effect on student learning outcomes. The test incorporated multiple-choice questions. In the implementation phase, the mean score of the pretest was 46.83, while the mean score of the posttest was 81.66. Afterward, the evaluation stage compared the posttest results and the school's passing grade (81.66 70), revealing that the developed learning media significantly affected student learning outcomes.
