<![CDATA[This study was motivated by the demands of twenty-first-century science education, which require elementary school students to develop scientific literacy and environmental responsibility. However, the implementation of Science and Social Studies (IPAS) learning on the topic of harmony in ecosystems in fifth grade elementary schools remains largely theoretical and focused on memorizing concepts without fostering students’ environmental awareness. The main problem addressed in this study was the low level of environmental awareness among fifth-grade students. Therefore, this study aimed to develop innovative Social Emotional Learning (SEL) based IPAS learning materials on the topic of harmony in ecosystems. This study employed a Research and Development (R&D) method using the 4D model, which consists of four stages: Define, Design, Development, and Disseminate. The subjects of this study were 35 fifth-grade students at SDN 2 Tambakrigadung. The research instruments included validation sheets, student response questionnaires, and student activity questionnaires. The results showed that the developed Social Emotional Learning (SEL)-based Science and Social Studies (IPAS) learning materials met the criteria of validity and practicality for classroom implementation. The validity of the learning materials was demonstrated through expert validation, while their practicality was evidenced by students learning activities and positive responses during the implementation trials. Therefore, the SEL based IPAS learning materials on the topic of harmony in ecosystems were considered valid and practical for use in elementary school learning. ABSTRAK Penelitian ini dilatarbelakangi oleh pendidikan sains abad-21 yang mengharuskan siswa sekolah dasar memiliki kemampuan literasi sains dan tanggung jawab terhadap lingkungan. Namun, implementasi pembelajaran IPAS pada materi harmoni dalam ekosistem kelas V di SD masih berbentuk teoritis dan hafalan konsep tanpa mengaitkan rasa kepedulian terhadap lingkungan di sekitar. Fokus masalah dalam penelitian ini adalah rendahnya kepedulian lingkungan yang dimiliki oleh siswa kelas V SD. Tujuan dari penelitian ini yaitu untuk mengembangkan inovasi perangkat pembelajaran IPAS berbasis Social Emotional Learning pada materi harmoni dalam ekosistem. Metode penelitian yang digunakan adalah metode pengembangan Research and Development (R&D) dengan model pengembangan 4D yang meliputi empat tahapan yaitu define, design, development, dan disseminate. Subjek penelitian yang digunakan adalah 35 siswa kelas V SDN 2 Tambakrigadung. Instrumen penelitian yang digunakan berupa lembar validasi, angket respon siswa dan angket aktivitas siswa. Hasil penelitian menunjukkan bahwa perangkat pembelajaran IPAS berbasis SEL yang dikembangkan memenuhi kriteria valid dan praktis untuk digunakan dalam proses pembelajaran. Validitas perangkat ditunjukkan oleh hasil penilaian para ahli, sedangkan kepraktisan perangkat ditunjukkan oleh aktivitas dan respons siswa selama uji coba. Dengan demikian, perangkat pembelajaran IPAS berbasis Social Emotional Learning pada materi harmoni dalam ekosistem dinyatakan valid dan praktis untuk digunakan.]]>
