Students' science process skills in chemistry learning will help students develop their thinking so they can prove the theories they have learned from maximum learning. Maximum learning is seen when students have a good understanding of what they have learned. In fact, students' science process skills are still relatively low, which has an impact on students' difficulty in understanding learnin…
This research aims to produce PBL-Based LKPD on the subject of chemical concepts and environmental management (green kimis) in everyday life.
