The development of a PQ4R-based electronic activity sheet on the material of ion balance and pH of the buffer solution aims to develop a valid electronic activity sheet and determine user responses in learning. The research method used is the research and development (R&D) method by applying a 4-D development model which includes Define, Design, Develop and Disseminate. Pandemic conditions cause research to only be carried out until the Develop stage which was followed by one-on-one trials,

The data analysis technique used is to calculate the results of the validation percentage score and user response. The results of the study explain that the PQ4R-based electronic activity sheet developed has been categorized as "valid" according to 2 material validation experts and 2 media validation experts based on the feasibility of content, PQ4R characteristics, language, presentation, display, and software utilization with average scores are 100%, 96.42%, 97.5%, 87.5%, 99%, and 98.21%. One-on-one trials were carried out on 3 students with different abilities to get comments that were used as improvements to the electronic activity sheet. The results of the user response test for 3 teachers and 20 students were categorized as "very good" with scores of 92.59% and 84.87%, respectively.
