PENGEMBANGAN LKPD BERBASIS ETNOMATEMATIKA MATERI LUAS PERMUKAAN BANGUN RUANG PADA KELAS VI SEKOLAH DASAR

"DEVELOPMENT OF STUDENT WORKSHEETS (LKPD) BASED ON ETHNOMATHEMATICS ON THE TOPIC OF SURFACE AREA OF SOLID FIGURES IN GRADE VI ELEMENTARY SCHOOL"

Penelitian ini merupakan penelitian pengembangan bahan ajar dengan model ADDIE (Analyze, Design, Development, Implementation dan implementation) di sekolah dasar. Tujuan penelitian ini adalah mengetahui proses pengembangan LKPD berbasis etnomatematika materi luas permukaan bangun ruang pada kelas VI sekolah dasar, mengetahui kelayakan yang ditinjau dari aspek kevalidan, kepraktisan dan keefektifan media, dan mengetahui respon pendidik serta peserta didik dalam penggunaan LKPD berbasis etnomatematika. Analisis data kevalidan diperoleh melalui validasi oleh ahli media dan materi. Tingkat kevalidan LKPD diperoleh dari hasil uji validasi oleh ahli materi sebesar 96% dengan kategori sangat valid, dan uji validasi oleh ahli media sebesar 96% dengan kategori sangat valid. Analisis data kepraktisan diperoleh melalui angket respon pendidik dan peserta didik. Tingkat kepraktisan LKPD diperoleh dari hasil angket respon peserta didik sebesar 95,5% dengan kategori sangat praktis dan angket respon pendidik sebesar 92,5% dengan kategori sangat praktis. Teknik analisis data keefektifan LKPD diperoleh dari hasil perhitungan ketuntasan belajar akhir berdasarkan aspek pengetahuan dan keterampilan sebesar 85,1% dengan kategori sangat efektif. Berdasarkan hasil data yang diperoleh, maka dapat disimpulkan bahwa LKPD berbasis etnomatematika memiliki nilai kevalidan, kepraktisan dan keefektifan yang tinggi sehingga layak digunakan oleh peserta didik dalam pembelajaran matematika materi bangun ruang pada kelas VI sekolah dasar.

This study is a research on the development of teaching materials using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation) in elementary schools. The aim of this research is to understand the process of developing worksheets (LKPD) based on ethnomathematics for the topic of surface area of three-dimensional shapes in sixth-grade elementary school, to determine the feasibility in terms of validity, practicality, and effectiveness of the media, and to understand the responses of educators and students in using ethnomathematics-based worksheets. The validity data analysis was obtained through validation by media and material experts. The validity level of the worksheets was obtained from the validation test results by material experts at 96%, categorized as very valid, and from the validation test by media experts at 96%, categorized as very valid. The practicality data analysis was obtained through questionnaires from educators and students. The practicality level of the worksheets was obtained from the student response questionnaire at 95.5%, categorized as very practical, and from the educator response questionnaire at 92.5%, categorized as very practical. The effectiveness data analysis technique of the worksheets was obtained from the calculation of final learning completeness based on knowledge and skills aspects at 85.1%, categorized as very effective. Based on the data obtained, it can be concluded that ethnomathematics-based worksheets have high validity, practicality, and effectiveness values, thus suitable for use by students in learning mathematics for the topic of three-dimensional shapes in sixth-grade elementary school.
