Penilitian ini bertujuan untuk menghasilkan perangkat pembelajaran matematika berbasis pemecahan masalah berorientasi pada kemampuan penalaran dan komonikasi matematika siswa  kelas X di SMK bidang keahlian akomodasi perhotelan. Jenis penelitian ini adalah penelitian pengembangan (Research and Development). Penelitian ini bertujuan utuk mengembangkan perangkat pembelajaran dengan menggunakan model pengembangan 3D (Define, Design, Develop) yang dikembangkan oleh Borg dan Gall.  Subyek penelitian ini adalah 65 siswa  kelas X SMK Negeri 6 Yogyakarta. Analisis data dilakukan dengan mengkonversi total skor aktual yang diperoleh menjadi data kualitatif skala lima. Penelitian ini menghasilkan perangkat pembelajaran matematika materi barisan dan deret  yang, meliputi  RPP, LKS, dan THB. Dari hasil validasi ahli, skor penilaian guru, penilaian siswa, observasi pembelajaran dan tes evaluasi menunjukkan bahwa RPP, LKS, dan THB  adalah  valid, praktis, dan efektif. Secara keseluruhan hasil penelitian menunjukkan bahwa perangkat pembelajaran yang dikembangkan adalah layak untuk digunakan.

It developed learning kits using   Borg and Gall development model, and the model was  modified so that it included only Define, Design, and Develop.   This study produced learning kits for the problem-based learning oriented reasoning ability and communication students for the topic of sequence and series. The kits consisted of lesson plan, student work sheet, and achievement test. The results of the validation   show that the developed kits are feasible to use and in the good category. The results of tryouts showed that the developed kits  are practical and effective to develop mathematics reasoning ability and mathematics communication of the students. The Practicality in tryout  was in good category with an average capability of being implemented in learning of 83.33 % and the field tryout us in the good category  with an average of improvement of 90.33%. Based on the  achievement test, it shows that  the achievement of learning outcomes with a minimum completeness is 78.33 %. Keywords: development, reasoning ability, communication of mathematics
