Good teaching materials hold up excellent learning. Good quality chemistry teaching materials contain all conceptual and representation aspects. The material for hydrolysis of salt and buffer solution is difficult for students, so learning media sources is needed to make it easier for students to understand the material. Learning materials for the hydrolysis of salt and buffer solutions will be more effective and efficient if students learn to use teaching materials developed by the teacher. Therefore, the aims of this research were to 1) Develop teaching materials for the hydrolysis of salt and buffer solutions based on understanding chemical concepts, chemical representations, and representational competence and 2) Determine the feasibility of teaching materials on salt hydrolysis and buffer solutions based on understanding chemical concepts, chemical representation, and representational competence. The research method used was a research and development method with a 4-D development model limited to three stages: defining, designing, and developing. The research instruments used were a validation questionnaire worksheet and a readability test. This research and development outcome was a teaching material product that refers to the 2013 curriculum syllabus. This product was verified by two validators, one chemistry lecturer at the State University of Malang and one chemistry teacher. The overall validation results showed an average percentage of 87%, meaning the product was very valid. The product readability test was carried out on 25 senior high school science students at Pasuruan; the average eligibility percentage was 91%, which means very feasible criteria. Therefore, this teaching material has the potential to enter a further stage in a limited-scale or wide-scale trial so that it is ready to enter the dissemination stage.
