Penelitian ini bertujuan untuk menghasilkan perangkat pembelajaran berbasis model IBMR, yang layak ditinjau dari kevalidan, kepraktisan, dan keefektifan. Model pengembangan yang digunakan pada penelitian ini adalah model Plomp dengan tahapan: 1) fase investigasi awal, 2) fase desain, 3) fase realisasi/konstruksi, 4) fase tes, evaluasi, revisi dan 5) fase implementasi. Perangkat pembelajaran yang telah dikembangkan divalidasi oleh tiga validator yang merupakan dosen FMIPA Universitas Negeri Surabaya. Tahap implementasi uji luas dilakukan di SMAN 1 Dagangan Kab.Madiun dengan subyek penelitian sebanyak tiga kelas. Desain uji coba one group pretest-posttest design. Pengumpulan data dilakukan dengan teknik validasi, observasi, tes kemampuan penyelesaian masalah, dan pengisian angket respon siswa terhadap pembelajaran. Data dianalisis secara deskriptif kuantitatif dan kualitatif. Data hasil penelitian yang diperoleh sebagai berikut: (1) validitas perangkat pembelajaran yang dikembangkan dianalisis dari tiga validator berkategori sangat valid; (2) keterlaksanaan pembelajaran dinilai oleh tiga pengamat dalam tiga kali pertemuan di tiga kelas dengan lembar observasi menunjukkan kategori sangat baik, (3) peningkatan kemampuan penyelesaian masalah fisika pada tiga kelas uji coba mayoritas menunjukkan kategori tinggi; (4) kemampuan multirepresentasi tiga kelas menunjukkan kategori tinggi yang berpengaruh pada kemampuan penyelesaian masalah fisika (4) siswa menunjukkan respon positif terhadap komponen pembelajaran dengan menggunakan model IBMR. Berdasarkan hasil analisis data, dapat disimpulkan bahwa perangkat pembelajaran berbasis model IBMR yang dikembangkan layak digunakan untuk meningkatkan kemampuan siswa menyelesaikan masalah fisika.

            This study aims to develop the learning materials based on the IBMR model, of its valid, practical, and effective. The Plomp model was used to develop them with the following phases: 1) the initial investigation, 2) the design, 3) the realization/ construction, 4) the test, the evaluation, and the revision and 5) the implementation. In this research, it used three validator and pengamats from State University of Surabaya for validating the learning material and observing the learning activities. The wide test implementation and assesment phases were carried out at SMAN 1 Dagangan Kab.Madiun with three classes as research subjects. One group pretest-posttest design was used to collect research data. The research instruments that used in this research were the sheets of validation, observation, problem solving skills tests, and filling out questionnaires for student responses to learning. The data obtained were analyzed descriptively, using quantitative and qualitative technic.The research results show: (1) the validity of the developed learning materials showing in very valid category, (2) the implementation of learning was assessed by three pengamats in three meetings, in three classes with the observation sheet showing the very good category, (3) the improving students' physics problem solving skill in the three test classes majority showed high category, (4) the multiplerepresentation ability of three classes shows a high category that affects the ability to solve physics problems almost and (5) all students give a positive response to the components of learning materials and process based on IBMR learning model. Based on the results, it can be concluded the learning materials based on IBMR learning model that developed is feasible to improve students' physics problem solving skills at Senior High School
