It is supporting the growth of industrial revolution 4.0 and at the same time also the answer for conducting teaching and learning activities during COVID-19 pandemic. The research goals to develop a system of flipped classroom based on guided inquiry learning on redox reactions and electrochemistry using Moodle as a learning management system that is valid and practical to support the teaching and learning activities for students and teacher. The research is an educational design research (EDR) using Plomp model consists of three stages: preliminary research, development or prototyping phases, and assessment phase. The preliminary research consists of needs and context analysis, literature review and the development of theoretical framework. The prototyping phase consists of prototype I until prototype IV with formative evaluation for each. In the prototype II, the validity of learning system was determined with the average validity score of 0.88 and is valid. In the prototype III, the practicality of learning system was determined with the average of practicality score of 85% is practical.
