PENGEMBANGAN MEDIA DIGITAL INTERAKTIF REDLE (RESPIRATORY DIGITAL LEARNING) UNTUK MENINGKATKAN HASIL BELAJAR IPA PESERTA DIDIK KELAS V SEKOLAH DASAR MATERI SISTEM PERNAPASAN MANUSIA

DEVELOPMENT OF INTERACTIVE DIGITAL MEDIA REDLE (RESPIRATORY DIGITAL LEARNING) TO ENHANCE SCIENCE LEARNING OUTCOMES OF GRADE V ELEMENTARY SCHOOL STUDENTS IN THE HUMAN RESPIRATORY SYSTEM MATERIALS

Penelitian ini merupakan penelitian pengembangan media pembelajaran interaktif REDLE (Respiratory Digital Learning) dengan menggunakan model ADDIE (Analyze, Design, Development, Implementation dan implementation) dengan materi sistem pernapasan manusia pada mata pelajaran IPA di kelas V  sekolah dasar. Penelitian ini bertujuan menilai kevalidan, kepraktisan, dan keefektifan produk media yang dikembangkan serta bertujuan untuk meningkatkan hasil belajar peserta didik pada materi terkait. Penelitian dilakukan di SDN Manukan Kulon dengan subjek penelitian merupakan 1 guru beserta 25 peserta didik kelas VC sebagai kelas eksperimen dan 30 peserta didik kelas VA sebagai kelas kontrol. Hasil penelitian menunjukkan kesuksesan media ini. Pertama, hasil validasi media REDLE mencapai skor 95,29% dengan kategori sangat valid. Validasi materi REDLE menghasilkan skor 90%, juga dengan kategori sangat valid. Kedua, kepraktisan REDLE menghasilkan persentase respon guru sebesar 94,74% dan dikategorikan sangat praktis. Respon peserta didik diperoleh persentase 95,5%, juga dikategorikan sangat praktis. Ketiga, keefektifan REDLE didapat dari persentase N-Gain antara kelas eksperimen dan kelas kontrol. Didapati perbedaan persentase N-Gain di kelas eksperimen sebesar 62%, kelas kontrol sebesar 44%. Hasil uji beda menunjukkan  bahwa nilai signifikansi sebesar 0,001 < 0,050, yang artinya terdapat perbedaan yang signifikan pada nilai N-Gain kelas eksperimen dan kelas kontrol. Secara keseluruhan, penggunaan media pembelajaran interaktif REDLE terbukti berpengaruh dalam meningkatkan hasil belajar peserta didik dalam pembelajaran IPA materi sistem pernapasan manusia di kelas V SD.

This study is a development research of interactive learning media called REDLE (Respiratory Digital Learning) using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation) with the topic of the human respiratory system in the science subject for fifth-grade elementary school students. The study aims to assess the validity, practicality, and effectiveness of the developed media product, as well as to enhance students' learning outcomes on the related topic. The research was conducted at SDN Manukan Kulon with the research subjects consisting of 1 teacher and 25 students in class VC as the experimental group, and 30 students in class VA as the control group. The results of the research indicate the success of this media. Firstly, the validation results of REDLE media reached a score of 95.29% with a category of very valid. The validation of REDLE material yielded a score of 90%, also with a very valid category. Secondly, the practicality of REDLE resulted in a percentage of teacher response of 94.74% and categorized as very practical. Student responses obtained a percentage of 95.5%, also categorized as very practical. Thirdly, the effectiveness of REDLE was obtained from the N-Gain percentage between the experimental and control groups. The difference in N-Gain percentage in the experimental group was found to be 62%, while in the control group it was 44%. The significance test results showed that the significance value was 0.001 < 0.050, which means there is a significant difference in the N-Gain values between the experimental and control groups. Overall, the use of interactive learning media REDLE has been proven to have an impact on improving students' learning outcomes in science learning, particularly on the topic of the human respiratory system in fifth-grade elementary school.
