<![CDATA[AbstrakTujuan dari penelitian dan pengembangan pendidikan ini adalah untuk (1) mengembangkan dan mendeskripsikan karakteristik perangkat pembelajaran yang selaras dengan model problem based learning melalui penalaran induktif pada topik laju reaksi. (2) mendeskripsikan validitas dan tingkat keterbacaan, dan (3) mengetahui keefektifan dari perangkat pembelajaran melalui uji coba pendahulu. Penelitian dan pengembangan (R&D) ini mengikuti model Borg dan Gall (1989) yang dibatasi pada tahap uji coba pendahuluan. Hasil penelitian dan pengembangan ini mampu mewujudkan perangkat pembelajaran model problem based learning dengan efektif. Perangkata pembelajaran yang dikembangkan dapat menghasilkan perangkat yang konsisten dan selaras mengikuti model problem based learning melalui penalaran induktif dengan pendekatan saintifik, memiliki tingkat validitas dan uji keterbacaan sangat baik dan baik., mendapatkan hasil belajar yang signifikan dengan nilai Normalitas Gain Score 0,55 dengan kategori sedang secara keseluruhan, penilian perindikator termasuk kategori tinggi untuk satu indikator dan sedang untuk enam indikator, peningkatan rata-rata pretest 23,27 menjadi rata-rata posttest 65,18, penilian aktivitas siswa dengan pendekatan saintifik 5 M dilihat dari penilian LKS secara umum meningkat, dan hasil tanggapan siswa terhadap proses pembelajaran dengan model problem based learning malalui penalaran induktif tergolong baik.Kata Kunci: model pembelajaran problem based learning, laju reaksi, penalaran induktif, pendekatan saintifik, dan perangkat pembelajaranAbstractThe purpose of this research and development education are to (1) develop and describe characteristics of learning devices that are in harmony with the problem based learning model through inductive reasoning on the topic of reaction rates, (2) describing the validity and readability level, and (3) knowing the effectiveness of learning device through a preliminary trial. This research and development (R & D) follows the Borg and Gall (1989) model which was limited to the preceding trial stage. The results of this research and development are able to realize a problem based learning model learning device effectively. It can, the results show that learning devices are consistent and harmonious can follow the problem based learning model through inductive reasoning with a scientific approach, have a very good and good level of validity and readability test, get significant learning outcomes with nilia Normality Gain Score 0.55 with categories is being Indicator evaluators are included in the high category for one indicator and medium for six indicators. The increase in the average pretest 23.27 becomes the average posttest 65.18, the assessment of student activity with the scientific approach 5 M seen from the LKS assessment generally increases, and the results of student responses to the learning process with problem based learning models through inductive reasoning are good .Keywords: problem based learning model, reaction rate, inductive reasoning, saintific approach, and learning tool]]>
