Abstract

INDONESIA: Penelitian ini bertujuan untuk mengembangkan Lembar Kerja Mahasiswa (LKM) terintegrasi keterampilan proses sains pada materi makrozoobentos yang layak dan praktis serta meningkatkan keterampilan proses sains mahasiswa. Metode penelitian yang digunakan yaitu R&D (Research and Development) dengan desain model 3D (Define, Design, dan Development). Instrumen penelitian ini terdiri dari angket validasi ahli, angket uji keterbacaan, tes pre-test serta post-test untuk melihat uji peningkatan hasil belajar, dan angket respons mahasiswa untuk menilai kepraktisan. Hasil penelitian menunjukkan bahwa validasi ahli yang terdiri dari validasi materi sebesar 83% kategori sangat layak, validasi media sebesar 78% kategori layak, validasi praktisi dosen pengampu sebesar 92% kategori sangat layak, dan uji keterbacaan sebesar 88,9 % kategori sangat layak. Peningkatan keterampilan proses sains mahasiswa sebesar 0,79 dengan kriteria n-gain tinggi. Indikator merencanakan percobaan dan menggunakan alat dan bahan memiliki skor n-gain tinggi. Hasil respons mahasiswa menunjukkan persentase 90,5% berkategori sangat baik. Lembar Kerja Mahasiswa yang dikembangkan layak digunakan serta praktis sebagai media pembelajaran dan dapat meningkatkan keterampilan proses sains mahasiswa pada materi makrozoobentos. ENGLISH: This research aims to develop Student Worksheets (LKM) that integrate science process skills on macrozoobentos materials that are feasible and practical and improve students' science process skills. The research method used is R&D (Research and Development) with 3D model design (Define, Design, and Development). This research instrument consists of an expert validation questionnaire, a readability test questionnaire, a pre-test and post-test test to see the test to improve learning outcomes, and a student response questionnaire to assess practicality. The results of the study showed that expert validation consisting of material validation of 83% of the category was very feasible, media validation of 78% of the feasible category, validation of practitioners of teaching lecturers of 92% of the category was very feasible, and readability test of 88.9% of the category was very feasible. An increase in students' science process skills of 0.79 with a high n-gain criterion. The indicator planned experiments and used tools and materials had a high n-gain score. The student response results showed that the percentage of 90.5% was categorized as very good. The Student Worksheets developed are suitable for learning media and can improve students' science process skills in macrozoobentos materials.
