    Abstract

    Perangkat pembelajaran berperan penting dalam menciptakan proses belajar yang efektif, salah satunya adalah Lembar Kerja Peserta Didik (LKPD). Studi pendahuluan menunjukkan bahwa LKPD di sekolah dasar umumnya belum memenuhi kriteria yang baik dan jarang memanfaatkan model pembelajaran model RADEC (Read, Answer, Discuss, Explain, Create) secara kontekstual. Penelitian ini bertujuan mengetahui karakteristik LKPD yang digunakan di sekolah dasar, mengembangkan LKPD berbasis RADEC pada materi siklus air, serta mendeskripsikan hasil uji coba produk. Metode yang digunakan adalah Design-Based Research (DBR) model Reeves, dengan teknik pengumpulan data melalui wawancara, studi dokumen, validasi ahli, dan angket respons guru serta peserta didik. Hasil validasi ahli materi memperoleh skor 87,3% (sangat layak), dan ahli desain 83,33% (sangat layak). Uji coba peserta didik menunjukkan praktikalitas sebesar 80% (baik) pada tahap pertama dan 94% (sangat baik) pada tahap kedua. Dengan demikian, LKPD berbasis RADEC yang dikembangkan valid, praktis, dan layak digunakan dalam pembelajaran IPA di sekolah dasar. Learning tools play a crucial role in creating an effective learning process, one of which is the Student Worksheet (LKPD). Preliminary studies indicate that LKPD in elementary schools generally do not meet good criteria and rarely utilize the RADEC (Read, Answer, Discuss, Explain, Create) learning model contextually. This study aims to determine the characteristics of LKPD used in elementary schools, develop a RADEC-based LKPD for the water cycle, and describe the results of product trials. The method used was the Reeves Design-Based Research (DBR) model, with data collection techniques including interviews, document studies, expert validation, and teacher and student questionnaire responses. The validation results from the material experts obtained a score of 87.3% (very acceptable), and from the design experts 83.33% (very acceptable). The student trials showed a practicality of 80% (good) in the first phase and 94% (very good) in the second phase. Thus, the developed RADEC-based LKPD is valid, practical, and suitable for use in science learning in elementary schools.
