PENGEMBANGAN MEDIA PEMBELAJARAN INTERAKTIF BERBASIS VIDEO POWTOON DAN GAME EDUCAPLAY UNTUK MENINGKATKAN PEMAHAMAN FOTOSINTESIS SISWA

Abstract

ABSTRACT The difficulty experienced by fourth-grade students at SDN 4 Rowomarto in understanding photosynthesis is related to the abstract nature of the topic and the limited use of learning media that support process visualization. This study aimed to develop interactive learning media based on Powtoon videos and Educaplay games for teaching photosynthesis and to determine their validity, practicality, and effectiveness. This study employed a Research and Development (R&D) method using the ADDIE model, consisting of Analysis, Design, Development, Implementation, and Evaluation stages. The participants were fourth-grade students at SDN 4 Rowomarto. The research instruments included expert validation sheets, teacher response questionnaires, student response questionnaires, and pretest and posttest assessments. The results showed that the media obtained validation scores of 83% from the media expert and 88% from the material expert, with an overall average of 85.5%, categorized as highly valid. The practicality results showed teacher responses of 92.5%, limited-trial student responses of 92.81%, and extensive-trial student responses of 88.65%, all categorized as highly practical. Effectiveness was indicated by an increase in learning mastery from 87.5% on the pretest to 100% on the posttest. Thus, the developed media met the criteria of validity, practicality, and effectiveness as an alternative for teaching photosynthesis to fourth-grade elementary school students. ABSTRAK Kesulitan siswa kelas IV SDN 4 Rowomarto dalam memahami materi fotosintesis berkaitan dengan karakteristik materi yang bersifat abstrak dan keterbatasan penggunaan media pembelajaran yang mendukung visualisasi proses. Penelitian ini bertujuan untuk mengembangkan media pembelajaran interaktif berbasis video Powtoon dan game Educaplay pada materi fotosintesis serta mengetahui tingkat kevalidan, kepraktisan, dan keefektifannya. Penelitian menggunakan metode Research and Development (R&D) dengan model ADDIE yang meliputi Analysis, Design, Development, Implementation, dan Evaluation. Subjek penelitian adalah siswa kelas IV SDN 4 Rowomarto. Instrumen penelitian meliputi lembar validasi ahli, angket respons guru, angket respons siswa, serta tes pretest dan posttest. Hasil penelitian menunjukkan bahwa media memperoleh validasi ahli media sebesar 83% dan ahli materi sebesar 88%, dengan rata-rata 85,5% berkategori sangat valid. Kepraktisan media memperoleh respons guru sebesar 92,5%, respons siswa pada uji coba terbatas sebesar 92,81%, dan uji coba luas sebesar 88,65%, seluruhnya berkategori sangat praktis. Keefektifan ditunjukkan oleh peningkatan ketuntasan belajar dari 87,5% pada pretest menjadi 100% pada posttest. Dengan demikian, media yang dikembangkan memenuhi kriteria valid, praktis, dan efektif sebagai alternatif pembelajaran materi fotosintesis bagi siswa kelas IV sekolah dasar.
