Penelitian ini bertujuan : (1) menghasilkan LKPD berbasis problem based learning yang layak pada mata pelajaran momentum dan impuls untuk peserta didik kelas X MIA (2) mengetahui keefektifan produk dalam meningkatkan minat belajar dan hasil belajar. Penelitian ini merupakan penelitian pengembangan (RD) dengan model 4-D menurut Thiagarajan. Subjek penelitian adalah MIA 1 dan MIA 2 MAN Godean. Instrumen penelitian meliputi LKPD, angket pretest dan posttest minat peserta didik, angket respon peserta didik, dan soal pretest dan posttest yang sudah dinyatakan valid dan reliabel. Teknik analisis dilakukan berdasarkan normalized gain. Hasil penelitian menunjukkan: (1) LKPD yang dikembangkan layak digunakan dengan kategori baik dan reliabel dengan kategori excellent, (2) peningkatan minat belajar peserta didik pada kelas X MIA 1 dan kelas X MIA 2 berturut-turut memiliki nilai normalized gain sebesar 0,3 dan 0,31 dengan kategori sedang, sedangkan peningkatan hasil belajar peserta didik pada kelas X MIA 1 dan kelas X MIA 2 berturut-turut memiliki nilai normalized gain sebesar 0,7 dengan kategori tinggi dan 0,58 dengan kategori sedang. Kata kunci: LKPD, Problem Based Learning, Hasil Belajar, Motivasi Belajar Abstract This research aimed to : (1) produce a student’s worksheet based the problem based learning that is appropriate on the subjects of momentum and impulse for students of class X MIA (2) discover the effectiveness of product in increasing the interest and the achievement of students. This research was a research and development (RD) using the 4D model by Thiagarajan. The subjects of this research were students in X MIA 1 and X MIA in Godean Islamic Senior High School. Instruments of this research were LKPD, pretest and posttest questionnaire of students' interest, student's response questionnaire, and pretest and posttest questions that have been declared valid and reliable. The analysis technique was based on normalized gain. The result showed that: (1) the developed student’s worksheet is proper done with good category and reliable to use it with excellent category. (2) the improvement of the interest of students in class X MIA 1 and class X MIA 2 that has the normalized gain value of 0.30 and 0.31 with middle category for both, whereas the achievement of students in class X MIA 1 and class X MIA 2 has the normalized gain value of 0.70 with high category and 0.58 with middle category. Keywords: student’s worksheet, problem based learning, the interest of physics instruction, the achievemnt of physics instruction.
