Abstract

Penelitian ini bertujuan menyusun perangkat pembelajaran yang berkarakteristik Problem Based Learning (PBL), menguji validitas, kefektifan dan kepraktisannya. Penelitian dilaksanakan di SMP Negeri 1 Keling Kabupaten Jepara dengan pendekatan Research and Development (R&D). Perangkat yang dikembangkan divalidasi oleh pakar, diuji keterterapannya pada skala kecil dan diuji efektivitasnya pada skala luas. Indikator efektivitas meliputi hasil belajar kognitif mencapai KKM ≥ 65, ketuntasan klasikal 85% tuntas belajar. Keterampilan berpikir siswa minimal 80% mencapai baik atau sangat baik. 80% siswa mempunyai sikap terhadap penolakan zat adiktif dan psikotropika. Hasil validasi silabus 97,1; validasi RPP 55; validasi LKS 73,7; validasi bahan ajar 174; dan validasi alat evaluasi 15,75.
