Abstract
The low level of students' conceptual understanding of junior high school (SMP) students regarding flat-sided solid geometry material is caused by conventional teaching methods, limited digital media, and teaching materials that have not been linked to local culture (ethnomathematics), causing students to tend to memorize formulas without understanding the concepts in depth. This research aims to develop and determine the validity, practicality, and effectiveness of an interactive mathematics E-LKPD (Electronic Student Worksheet) based on ethnomathematics of local Magetan architecture for flat-sided solid geometry material for junior high school students. The research uses a Research and Development (R&D) approach with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The research subjects were eighth-grade students of SMP Negeri 1 Kawedanan, selected through purposive sampling, comprising class VIII-B for the limited trial (10 students) and class VIII-A for the field trial (27 students). Data were collected through interviews, observations, expert validation questionnaires, student response questionnaires, and pre-tests and post-tests, analyzed using descriptive percentage statistics, Paired Sample T-Test, Wilcoxon Signed Rank test, and N-Gain. The results showed a validity of 89.6% (very valid), practicality of 88.4% in the limited trial and 85.7% in the field trial (very practical), and effectiveness with N-Gain in the moderate category (0.533 and 0.421) accompanied by classical mastery above 80%. Based on the analysis results, it is known that this E-LKPD is valid, practical, and effective, so it can be used as an alternative teaching material that integrates local culture into the learning of flat-sided solid geometry at the junior high school level.
