Penelitian ini bertujuan untuk mengembangkan suatu produk berupa perangkat pembelajaran matematika realistik dengan peta konsep pada materi trigonometri di kelas XI SMK yang meliputi: buku siswa, buku petunjuk guru, dan rencana pelaksanaan pembelajaran. Jenis penelitian ini adalah penelitian pengembangan. Subjek dalam penelitian ini adalah ahli, guru, dan siswa kelas XI SMK. Validitas perangkat pembelajaran didasarkan atas pendapat validator, kepraktisan didasarkan atas keterlaksanaan, respons guru dan siswa, dan keefektivan didasarkan atas hasil belajar matematika siswa. Pengembangan perangkat pembelajaran ini mengikuti prosedur pengembangan produk dari Plomp yang meliputi lima tahap, yaitu: (1) investigasi awal; (2) desain; (3) realisasi/konstruksi; (4) tes, evaluasi, dan revisi; dan (5) implementasi. Dalam penelitian ini, tahapan yang dilakukan hanya sampai menghasilkan produk final dan tidak dilakukan implementasi secara luas. Hasil penelitian menunjukkan bahwa perangkat pembelajaran matematika realistik ini telah valid, praktis, dan efektif yang memiliki karakteristik sebagai berikut. Buku siswa memiliki karakteristik: (1) berorientasi pada masalah realistik dan (2) disusun secara hierarkis dan sistematis melalui peta konsep. Buku petunjuk guru memiliki karakteristik: (1) memberikan gambaran mangenai keruntutan materi melalui peta konsep dan (2) memberikan gambaran mengenai kegiatan pembelajaran. Rencana pelaksanaan pembelajaran memiliki karakteristik yaitu disusun sesuai dengan karakteristik pembelajaran matematika realistikKata Kunci : pembelajaran matematika realistik, peta konsep,trigonometri, hasil belajar matematika This study aimed at developing products which were considering realistic mathematics teaching-learning instruments with concept map for trigonometry concepts at eleventh grade of vocational school which consist of studentâs textbook, teacherâs guidance book, and lesson plan. This was a developmental research. The subjects of this study were experts, teachers, and students of eleventh grade at vocational school. The quality of the teaching-learning instruments is considered from three aspects; validity, practicality, and effectiveness. The developmental of the teaching-learning instruments is based on the procedure of developing product by Plomp which includs five phases: (1) preliminary investigation; (2) design, (3) realization/construction, (4) test, evaluation, and revision; and (5) implementation. This study was conducted until gaining the final product and was not widely implemented yet. The result of this study showed that the developed realistic mathematics teaching-learning instruments had been valid, practics, and effective. The characteristics of studentsâ textbook were (1) mathematics realistic problems oriented and (2) designed hierarchically and systematically with the concept map. The characteristics of teachersâ textbook were (1) giving an overview of a coherent materials and (2) giving an overview of teaching-learning activities. The characteristics of lesson plan is designed based on the realistic mathematics educationkeyword : realistic mathematic education, the concept map, trigonometry, mathematic learning outcomes
