Keterampilan berpikir kritis penting dilatihkan pada peserta didik dalam menyelesaikan masalah aktual. Model pembelajaran yang dapat mengembangkan keterampilan berpikir kritis dengan memunculkan informasi dari pengalaman kehidupan sehari–hari dan masalah aktual yakni Problem Based Learning.  Penelitian ini bertujuan untuk menghasilkan suatu bahan ajar berupa LKPD berbasis problem based learning pada materi perubahan lingkungan untuk melatihkan keterampilan berpikir kritis peserta didik kelas X SMA yang valid, praktis, dan efektif. Penelitian ini merupakan penelitian pengembangan dengan menggunakan model 4D yang terdiri dari tahap define, design, develop, dan disseminate, namun pada tahap disseminate tidak dilakukan. Tahap pengembangan LKPD dilakukan di Jurusan Biologi, FMIPA, Universitas Negeri Surabaya. Ujicoba terbatas dilakukan pada 16 peserta didik kelas X SMA Negeri 1 Kota Mojokerto. Metode pengumpulan data yang digunakan adalah validasi, observasi, tes, dan hasil angket respon peserta didik. Hasil dari penelitian menunjukkan bahwa validitas LKPD berbasis problem based learning memperoleh modus keseluruhan dengan kategori sangat valid. Kepraktisan LKPD ditinjau dari hasil keterlaksanaan LKPD sebesar 95,13% dengan kategori sangat baik dan keterlaksanaan keterampilan berpikir kritis sebesar 90,77% dengan kategori sangat baik. Keefektifan LKPD ditinjau dari ketuntasan hasil belajar peserta didik sebesar 87,5% dengan kategori sangat tuntas, persentase ketuntasan indikator pembelajaran sebesar 90,63% dengan kategori sangat tuntas, persentase ketercapaian keterampilan berpikir kritis 81,5% dengan kategori sangat tinggi, dan persentase hasil angket respons peserta didik sebesar 95,31% dengan kategori sangat baik. Berdasarkan hasil yang telah diperoleh dapat disimpulkan bahwa Lembar Kegiatan Peserta Didik berbasis Problem Based Learning pada Materi Perubahan Lingkungan untuk Melatihkan Keterampilan Berpikir Kritis dinyatakan valid, praktis dan efektif sehingga dapat digunakan dalam proses pembelajaran.

Kata Kunci: Lembar kegiatan peserta didik, problem based learning, perubahan lingkungan, keterampilan berpikir kritis.

Critical thinking skill is important to train students solving an actual problem. Problem based learning is a learning model that can develop critical thinking skill by producing information based on life experiences and actual problem.  This study aimed to produce a valid, practical and effective student worksheet based on problem based learning in the environmental changes material to trained critical thinking skill for 10^th grade students. This study was used 4D model that consists of define, design, develop, and disseminate stages. However, the disseminate stage was not contributed in this study. The development stage of student worksheet was organized in Biology Department, Faculty of Mathematics and Natural Sciences, State University of Surabaya. Limited trials was conducted to the sixteen 10^th grade students of SMA Negeri 1 Mojokerto. Collecting data methods was validation, observation, tests, and students response questionnaire result. The results showed that the validity of student worksheet based on problem based learning was acquired overall mode in a valid category. The practicability of students worksheet was measured of 95,13% belong to the very good category, and the performance of critical thinking skill amounts 90,77% showed to the good category. The effectiveness of students worksheet could be viewed by the completeness in the result of students learning which amounts 87,5% in very completed category, thus the percentage of learning indicators was amount 90,63% which also in very completed category. The percentage of critical thinking skill achievement was 81,5% with the highest category and the percentage of students response questionnaire result was 95,31% which showed as the highest category. The result can be concluded that student worksheet based on problem based learning in environmental changes material to train critical thinking skill were valid, practical, and effective to used in teaching and learning process.
