<![CDATA[Abstrak Penelitian ini bertujuan untuk mengembangkan modul ajar berbasis etnomatematika untuk meningkatkan literasi matematis yang valid, praktis dan efektif untuk digunakan. Penelitian dilakukan di SMP Negeri 4 Tuhemberua Tahun Pelajaran 2023/2024 di kelas VII. Instrumen penelitian terdiri dari angket validasi ahli bahasa, materi, dan desain; angket respon peserta didik; angket respon guru dan tes hasil belajar peserta didik dalam menggunakan produk yang dikembangkan. Analisis data dilakukan secara kualitatif dan kuantitatif. Berdasarkan hasil penelitian, modul yang dibuat telah teruji sangat layak oleh validator ahli bahasa instrumen angket sebesar 98,66%, ahli bahasa pada modul sebesar 100%, ahli materi I sebesar 99,5%, ahli materi II sebesar 97,9%, ahli desain sebesar 94,2%. Modul yang dikembangkan sangat praktis digunakan dengan presentase 92,2%. Selanjutnya, modul juga efektif digunakan dengan presentase sebesar 87,10%. Berdasarkan hasil penelitian tersebut, modul berbasis etnomatematika tergolong efektif untuk meningkatkan literasi matematis siswa.

The research was conducted at SMP Negeri 4 Tuhemberua in the 2023/2024 academic year in class VII. The research instrument consisted of a validation questionnaire for linguists, materials, and design; student response questionnaire; teacher response questionnaire and student learning outcomes test in using the developed product. Data analysis was carried out qualitatively and quantitatively. Based on the results of the study, the module made has been tested very feasible by the validator linguist instrument questionnaire of 98.66%, language experts on the module by 100%, material experts I by 99.5%, material experts II by 97.9%, design experts by 94.2%. The developed module is very practical to use with a percentage of 92.2%. Furthermore, the module is also effective to use with a percentage of 87.10%. Based on the results of this study, the ethnomathematics-based module is classified as effective for improving students' mathematical literacy.
