Penelitian ini dilatarbelakangi oleh rendahnya pemahaman konsep siswa terhadap materi sistem pencernaan manusia serta belum optimalnya pemanfaatan media pembelajaran digital di SDN Sindang 1. Tujuan penelitian ini adalah untuk mengembangkan media pembelajaran interaktif berbasis Macromedia Flash 8 dan menguji kelayakan serta efektivitasnya dalam meningkatkan pemahaman konsep siswa kelas V. Metode yang digunakan adalah Research and Development (R&D) dengan model pengembangan ADDIE yang meliputi lima tahap: Analyze, Design, Development, Implementation, dan Evaluate. Subjek penelitian melibatkan dua kelas, yaitu kelas VA sebagai kelas eksperimen dan VB sebagai kelas kontrol. Media pembelajaran yang dikembangkan memuat materi, animasi proses pencernaan, simulasi sederhana, kuis interaktif, serta audio pendukung. Hasil validasi dari ahli media dan ahli materi menunjukkan bahwa media ini sangat layak digunakan dengan rata-rata skor kelayakan di atas 89%. Uji efektivitas dilakukan melalui pre-test dan post-test. Hasil analisis menunjukkan terdapat perbedaan signifikan antara hasil belajar kelas eksperimen dan kelas kontrol, dengan nilai t-hitung (4,270) > t-tabel (2,024) pada taraf signifikansi 0,05. Rata-rata nilai N-Gain sebesar 0,71 termasuk kategori tinggi. Dengan demikian, media pembelajaran berbasis Macromedia Flash 8 dinyatakan layak dan efektif dalam meningkatkan pemahaman konsep siswa pada pembelajaran IPAS, khususnya materi sistem pencernaan manusia.
This research was motivated by the low conceptual understanding of students regarding the human digestive system material and the suboptimal use of digital learning media at SDN Sindang 1. The purpose of this study is to develop interactive learning media based on Macromedia Flash 8 and to test its feasibility and effectiveness in improving the conceptual understanding of fifth-grade students. The method used is Research and Development (R&D) with the ADDIE development model, which consists of five stages: Analyze, Design, Development, Implementation, and Evaluation. The research subjects involved two classes: class VA as the experimental group and class VB as the control group. The developed learning media includes material content, digestive system animations, simple simulations, interactive quizzes, and supporting audio. Validation results from media and content experts indicate that the media is highly feasible, with an average feasibility score above 89%. Effectiveness testing was conducted using pre-tests and post-tests. The results of the analysis show a significant difference between the learning outcomes of the experimental and control classes, with a t-value (4.270) greater than the t-table value (2.024) at a significance level of 0.05. The average N-Gain score was 0.71, which is classified as high. Therefore, the Macromedia Flash 8-based learning media is declared to be feasible and effective for improving students’ conceptual understanding in IPAS learning, particularly on the topic of the human digestive system.
