Development of E-Modules Based on Batak Toba Local Wisdom on Biodiversity to Improve Learning Outcomes of Grade X Students

Abstract

Penelitian ini bertujuan untuk mengembangkan E-Modul berbasis kearifan lokal Batak Toba pada materi keanekaragaman hayati, serta mengetahui kelayakan, respon peserta didik, dan pengaruhnya terhadap hasil belajar siswa kelas X SMA Negeri 2 Pematangsiantar. Penelitian ini menggunakan metode Research and Development (R&D) dengan model pengembangan ADDIE (Analysis, Design, Development, Implementation, Evaluation) yang dipadukan dengan desain Pretest-Posttest Control Group Design. Sampel penelitian ditentukan melalui teknik purposive sampling, yaitu kelas X-4 sebagai kelas eksperimen dan kelas X-10 sebagai kelas kontrol, masing-masing berjumlah 36 siswa. Data dikumpulkan melalui angket validasi ahli, angket respon peserta didik, serta tes hasil belajar berbentuk soal pilihan ganda, kemudian dianalisis secara deskriptif dan melalui uji independent sample t-test. Hasil penelitian menunjukkan bahwa E-Modul yang dikembangkan dinyatakan sangat layak berdasarkan penilaian delapan validator pada aspek isi materi, penyajian, desain, dan bahasa. Peserta didik juga memberikan respon yang sangat positif terhadap penggunaan E-Modul. Rata-rata nilai posttest kelas eksperimen meningkat dari 48,0% menjadi 81,3%, lebih tinggi dibandingkan kelas kontrol yang meningkat dari 26,3% menjadi 68,1%. Hasil uji independent sample t-test menunjukkan nilai signifikansi sebesar 0,024 (< 0,05), yang berarti terdapat pengaruh signifikan penggunaan E-Modul terhadap hasil belajar siswa. Dengan demikian, E-Modul berbasis kearifan lokal Batak Toba layak digunakan sebagai bahan ajar alternatif yang mampu meningkatkan hasil belajar peserta didik pada materi keanekaragaman hayati.

This study aimed to develop an E-Module based on Batak Toba local wisdom on biodiversity materials, and to determine its feasibility, students' responses, and its effect on the learning outcomes of tenth-grade students at SMA Negeri 2 Pematangsiantar. This study used the Research and Development (R&D) method with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation) combined with a Pretest-Posttest Control Group Design. The sample was determined through purposive sampling, namely class X-4 as the experimental class and class X-10 as the control class, each consisting of 36 students. Data were collected through expert validation questionnaires, student response questionnaires, and multiple-choice learning outcome tests, then analyzed descriptively and through an independent sample t-test. The results showed that the developed E-Module was categorized as very feasible based on the assessment of eight validators covering content, presentation, design, and language aspects. Students also gave a very positive response to the use of the E-Module. The average posttest score of the experimental class increased from 48.0% to 81.3%, higher than the control class which increased from 26.3% to 68.1%. The independent sample t-test showed a significant value of 0.024 (< 0.05), indicating a significant effect of the E-Module on students' learning outcomes. Thus, the Toba Batak local wisdom-based E-Module is feasible to be used as an alternative teaching material that can improve students' learning outcomes on biodiversity material.
