Penelitian ini bertujuan untuk menghasilkan Lembar Kerja Peserta Didik (LKPD) untuk kelas IV dalam pembelajaran Ilmu Pengetahuan Alam dan Sosial (IPAS) pada materi wujud zat dan perubahannya di SDN 032 Tarakan serta menghasilkan LKPD yang layak digunakan dan mengetahui respon kemenarikan LKPD yang ditinjau dari validasi ahli materi, ahli bahasa, ahli media dan ahli praktisi serta angket respon siswa terhadap kemenarikan LKPD. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan model pengembangan ADDIE yang terdiri dari lima tahap: Analysis (analisis), Design (desain), Development (pengembangan), Implementation (implementasi), dan Evaluation (evaluasi). Hasil validasi ahli materi diperoleh skor persentase sebesar 95%, validasi ahli bahasa diperoleh skor persentase sebesar 94,4%, validasi ahli media diperoleh skor persentase sebesar 92,5%, dan validasi ahli praktisi diproleh skor persentase sebesar 92,5% sehingga mendapat skor rata-rata persentase yaitu sebesar 93,6% dengan kategori sangat valid. Adapun hasil respon siswa terhadap kemenarikan LKPD pada saat uji coba terbatas diperoleh skor persentase sebesar 79% dengan kategori menarik dan 83% pada uji coba lapangan dengan kategori sangat menarik.

This study aimed to produce Student Worksheets (LKPD) for class IV in Natural and Social Sciences (IPAS) learning on material phase transitions and their changes at SDN 032 Tarakan as well as producing LKPD that is suitable for use and knowing the response to the attractiveness of the LKPD in terms of validation material experts, language experts, media experts, practitioner experts, and student response questionnaires regarding the attractiveness of LKPD. The research method used is Research and Development (R&D) with the ADDIE development model which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. The results of material expert validation obtained a percentage score of 95%, linguist validation obtained a percentage score of 94.4%, media expert validation obtained a percentage score of 92.5%, and practitioner expert validation obtained a percentage score of 92.5% so that it received the average percentage score of 93.6% with a very valid category. The results of students' responses to the attractiveness of the LKPD during the limited trial obtained a percentage score of 79% in the interesting category and 83% in the field trial in the very interesting category.
