Abstract

Chemical equilibrium is a material studied in class grade eleven for senior high school which consists of theory and practicum, so that teaching materials are needed that can support the characteristics of this material. This study aims to produce a chemical equilibrium e-module based on integrated guided inquiry (IGI) to reveal the level of validity and practicality. The type of research used is research and development (R&D). The development model used is Plom which consists of three stages, namely preliminary research, prototyping phase, and assessment phase. The research instrument used was a questionnaire in the form of a validity and practicality sheet. The data obtained from the research instrument were analyzed using the Aiken'V formula, and percentage. Based on the results of data analysis with the Aiken'V formula, the construct validity was 0.89 in the valid category, while for the technical, the Aiken'V value was 0.90% in the valid category. For the practicality assessment by the teacher, 91.49% was obtained in the very practical category and the practicality by the students was 87.84% in the very practical category. It is concluded that the product developed is valid and very practicaly
