摘要:This study aims to look at the effect of the implementation of the use of the "Protein Concentration Analysis" module on student learning outcomes and responses to Biochemical II learning. This research is a type of research and development (Research and Development) which aims to investigate patterns and sequences of growth or change as a function of time. Based on the results of this study it is known that the average pretest score of students before using the module is 56.34 ± 11.65 with the lowest score of 33, and the highest score of 73, and the most scores obtained by students range from 60-69, while the average posttest results the average student after using the module is 84.68 ± 8.67, with the lowest score of 60, and the highest score of 100. Based on the learning outcomes that have been carried out it is known that the learning process using the module gives an increase in learning outcomes in Chemistry Education students VI Semester FKIP UNIB. The results of the questionnaire responses of students to learning activities using modules are in the good category which is at a score of 46.8, and the response of students to the modules used in learning is at a score of 19.2 with good categories.
