Research on the development of E-LKPD teaching materials based on problem solving approaches is motivated by teaching materials that have not been maximized and there is still no innovation at SMPN 1 Rumbia. This study aims to develop E-LKPD teaching materials based on a problem solving approach to meet the needs of learning productivity. The quality of product development must meet the criteria in terms of validity and practicality. This responses received a positive response from filling out student response questionnaires with a percentage value of 92% included in the "Very Practical" criteria. Thus it can be concluded that the E-LKPD is based on a problem solving approach on the two-variable linear equation system material that has been developed to be feasible and very practical to use in learning mathematics.study uses development research that refers to the Borg and Gall model which includes: potentials and problems, data collection, product design, design validation, design revisions, product trials, and product revisions. The instruments used were: an assessment questionnaire by material experts and media experts and a practicality questionnaire for student responses. The results of the assessment by material experts obtained an overall score of 176 with an average value of 4.38 included in the "Strongly Agree" interpretation category. The results of the media expert validation obtained an overall score of 135 with an average value of 3.89 included in the "Agree" interpretation criterion. The results of student.
