SUMMARY
Pengembangan Modul Reaksi Redoks berorientasi PBL (Problem Based Learning) telah dilakukan . Jenis penelitian ini adalah Research and Development (R and D) yang telah dimodifikasi sesuai kebutuhan. Penelitian ini meliputi empat tahap, yaitu analisis kebutuhan materi, perancangan dan pengembangan modul, standarisasi modul berdasarkan BSNP (Badan Standar Nasional Pendidikan) oleh Dosen dan Guru Kimia serta uji coba kepada 12 orang siswa kelas X-MIPA3 SMA Negeri 14Medan. Hasil penelitian menunjukkan bahwa modul yang dikembangkan memenuhi kriteria BSNP, dengan kelayakan isi (3,58), kelayakan bahasa sebesar (3,56); kelayakan penyajian (3,65); dan kelayakan kegrafikan 3,72 serta siswa memberi tanggapan sangat baik terhadap bahan ajar modul yang disusun dengan perolehan skor rata-rata angket sebesar 3,45. Development of PBL-oriented Redox Reaction Modules (Problem Based Learning) has been implemented. This research belongs to the type of Research and Development (R and D) study that has been modified as needed. This study includes four stages, namely material requirements analysis, module design and development, module standardization based on BSNP (National Education Standards Agency) by Chemistry Lecturers and Teachers, and trials conducted on 12 students of class X-MIPA3 Medan 14 High School. The results of the study indicate that the module developed fulfills the BSNP criteria, with content eligibility (3.58), language feasibility of (3.56); presentation feasibility (3.65); and graphical feasibility of 3.72, and students gave very good responses to module teaching materials compiled with the acquisition of an average score of 3.45 questionnaires
