Developing Physics Learning Tools Based on Local Wisdom in the Form of Musical Instrument of Gandrang Bulo Dance as Learning Source in Sound Wave

This was a development research that aimed to (1) produce physics learning tools based on local that are feasible  to be used in  learning, and (2) determine the quality of learning tools  that have been developed. This research was using 4D model which consisted of defining, designing, developing. and disseminating.  Learning tools that were developed consist of Lesson Plan (RPP), Student Worksheets (LKPD), teaching materials, and learning media. The results of the feasibility test showed that the learning tools were in the good and feasible categories based on qualitative and quantitative assessments of experts, physics teachers, and peers with an average score of 26,4 – 35,2. In addition, the results of testing the learning tools in 30 randomly selected students showed a result of the average response responses of students of 3.08 with good and feasible categories to be used in the learning process on a larger scale. Furthermore, each phase of activity contained in the lesson plan has been carried out very well in each of its meetings based on the observations of learning implementation with achievement scores reaching 80% - 100%
