Abstract

ABSTRAK Seseorang memiliki kecerdasan intelektual, sikap yang baik dan keterampilan yang memberi manfaat dikemudian hari bagi dirinya sendiri maupun lingkungan sekitar dengan adanya pendidikan. Proses pembelajaran biologi harus diperbaharui, semula pembelajaran (teacher centered) artinya pendidik sebagai sumber belajar menjadi pembelajaran berpusat pada peserta didik (student centered). Oleh karena itu model yang peneliti gunakan yaitu Model pembelajaran problem based learning berbantuan Liveworksheets dengan materi sistem pernapasan yang bertujuan untuk memberikan inovasi terdapat vitur seperti melihat cuplikan video atau audio tujuannya untuk meningkatkan kemampuan berpikir kritis pada peserta didik tercapai. Penelitian ini adalah jenis kuantitatif dengan menggunakan metode Quasi eksperimen. Populasi dalam penelitian ini adalah seluruh peserta didik kelas XI IPA SMA N 08 Bandar Lampung sebanyak 105 peserta didik yang didistribusikan dalam 4 kelas. Sampel pada penelitian ini diambil dengan teknik cluster random sampling dan memperoleh kelas XI IPA 2 sebagai kelas kontrol dan kelas XI IPA 4 sebagai kelas eksperimen. Berdasarkan hasil analisis data pretest dan posttest yang menggunakan uji Independent Sample T-Test untuk menjawab hipotesis. Uji normalitas dilakukan menggunakan uji Shapiro-Wilk. Kemudian uji homogenitas dilakukan menggunakan uji homogeneity of variances. Hasil penelitian menunjukkan bahwa terdapat pengaruh problem based learning berbantuan Liveworksheets terhadap kemampuan berpikir kritis peserta didik kelas XI pada materi sistem pernapasan di SMA Negeri 08 Bandar Lampung yang ditunjukkan pada nilai sig. 0.000 < 0.05 artinya H0 ditolak H1 diterima. Hal ini menunjukkan bahwa terdapat pengaruh model pembelajaran problem based learning berbantuan Liveworksheets terhadap kemampuan berpikir kritis peserta didik kelas XI pada materi sistem pernapasan di SMA Negeri 08 Bandar Lampung. Kata Kunci : Kemampuan berpikir kritis, Liveworksheets, problem based learning, dan Sistem pernapasan. iii ABSTRACT A person has intellectual intelligence, good attitude and skills that will benefit himself and the environment in the future with education. The biology learning process must be renewed, originally learning (teacher centered) means that educators as learning resources become student centered learning (student centered). Therefore, the model that researchers use is a problem-based learning model assisted by Liveworksheets with respiratory system material which aims to provide innovation with features such as viewing video or audio footage, the aim is to improve students' critical thinking skills. This research is a quantitative type using quasi-experimental methods. The population in this study were all students of class XI IPA SMA N 08 Bandar Lampung totaling 105 students who were distributed in 4 classes. The sample in this study was taken by cluster random sampling technique and obtained class XI IPA 2 as the control class and class XI IPA 4 as the experimental class. Based on the results of the pretest and posttest data analysis using the Independent Sample T-Test to answer the hypothesis. The normality test was performed using the Shapiro-Wilk test. Then the homogeneity test was carried out using the homogeneity of variances test. The results showed that there was an influence of problem-based learning assisted by Liveworksheets on the critical thinking skills of class XI students in the material on the respiratory system at SMA Negeri 08 Bandar Lampung which was indicated by the sig. 0.000 < 0.05 means that H0 is rejected, H1 is accepted. This shows that there is an influence of the problem-based learning model assisted by Liveworksheets on the critical thinking skills of class XI students on the respiratory system material at SMA Negeri 08 Bandar Lampung. Keywords: Critical thinking skills, Liveworksheets, problem based learning, and the respiratory system.
