The research method used is the research and development method (Research and Development/R&D). The results of the research that has been done show the feasibility of LKPD according to material experts and media experts. Material validation was carried out twice, so that an average score of 45 was obtained with a percentage of 90% and included in the "Very Good" category while media validation was carried out twice, so that an average score of 40 was obtained with a percentage of 80% and included in the category " Well". This is supported by the results of field trials from small group trials obtained an average score of 43.9 with a percentage of 87.8% so that it has a very good category and the results of the teacher's response obtained an average score of 44 with a percent value 88% has a very good category.
