ABSTRACT
This research is motivated by the demand of 21st century on a learning approach that helps students to build their knowledge based on real-world contexts. This learning approach is called Problem Based Learning. This research aims to collect information regarding the implementation of Problem Based Learning in the context of maintaining the freshness of Soursop juice. The method used in this research is pre-experiment, and the design used in this research is one group pretest posttest design. This research is carried out on one of SMAN (public high school) in Bandung. The subjects of this research consist of 32 students of class XII IPA. The instruments used in this research are teaching and learning plan assessment format, LKS assessment format, attitude and skill asessment format, and test items. The implementation of Problem Based Learning in the students’ mastery of concepts is measured based on the results of pretest and posttest that are analyzed using SPSS v. 20 for Windows. The result of this research shows that the teachers’ performance in planning and implementing Problem Based Learning is excellent (95%). The students’ performance in performing Problem Based Learning is also excellent in the aspect of cognitive (81%), attitude (96%), and skill (92%). The students’ mastery of concepts is increased significantly by 40%. Based on this statistical test, there is a significant improvement in the students’ mastery of concepts after they are given the treatment of Problem Based Learning. This shows that the implementation of Problem Based Learning is effective in improving the students’ mastery of concepts.
