Abstract

This research and development study of BPBL (Blended Problem-Based Learning) teaching materials aimed to measure their effectiveness on students’ learning outcomes in extraction and chromatography courses, as well as on students’ soft skills. Based on a preliminary questionnaire regarding the need for developing BPBL teaching materials, students reported difficulties in understanding the concepts of extraction and chromatography, resulting in learning outcomes that did not meet the required standards. Students also recognized that improving soft skills is important for personal development, social participation, and success in the workplace. BPBL teaching materials combine blended learning and problem-based learning approaches. The use of coffee as a contextual topic was intended to provide meaningful learning experiences and help students more easily understand the concepts in extraction and chromatography courses. The effectiveness of BPBL teaching materials on students’ learning outcomes showed an n-gain score of 0.64 (64%), while the effectiveness on students’ soft skills showed an n-gain score of 0.31 (31%). Both results were categorized as having moderate effectiveness.
