<![CDATA[Model problem based learning merupakan suatu pendekatan pembelajaran yang mendorong peserta didik untuk bersentuhan langsung dengan fakta permasalahan di lingkungan mereka secara nyata. SMAN 8 Banjarmasin adalah salah satu SMA yang belum terbiasa menggunakan model problem based learning. Penelitian ini bertujuan untuk mendeskripsikan (1) pengaruh penerapan model problem based learning terhadap hasil belajar materi konsep sistem ekskresi pada peserta didik kelas XI SMAN 8 Banjarmasin (2) hasil belajar materi konsep sistem ekskresi pada peserta didik kelas XI SMAN 8 Banjarmasin dengan menggunakan model problem based learning. Subjek penelitian ini sebanyak 69 orang peserta didik yang dibagi ke dalam 2 kelas yaitu XI MIPA 3 sebagai kelas kontrol menggunakan model direct intruction dan XI MIPA 2 sebagai kelas eksperimen menggunakan model problem based learning. Penelitian ini dilakukan dengan quasi experiment dengan desain penelitian the nonequivalent control group design. Teknik analisis data menggunakan uji Wilcoxon dan deskriptif. Hasil penelitian ini menunjukkan (1) penerapan model problem based learning materi konsep sistem ekskresi berpengaruh secara signifikan terhadap hasil belajar kognitif produk pada peserta didik kelas XI SMAN 8 Banjarmasin dengan nilai Asymp.Sig. (2-tailed) < 0,05 yaitu 0,000, (2) Hasil belajar yang meliputi kognitif proses dengan penerapan model problem based learning termasuk dalam dalam kategori baik, hasil belajar afektif perilaku berkarakter (tanggung jawab) dalam kategori baik, hasil belajar afektif perilaku berkarakter (santun) dalam kategori sangat baik, serta perilaku sosial (bekerjasama) dalam kategori sangat baik dan perilaku sosial (menyumbangkan pendapat) termasuk dalam kategori baik, dan hasil belajar psikomotorik termasuk dalam kategori baik Abstract The problem based learning model is a learning approach that encourages students to be in direct contact with real problems in their environment. SMAN 8 Banjarmasin is one of the high schools that is not used to using the problem based learning model. This study aims to describe (1) the effect of applying the problem-based learning model on learning outcomes of excretion system concept material in class XI students of SMAN 8 Banjarmasin (2) learning outcomes of excretion system concept material in class XI students of SMAN 8 Banjarmasin using the problem model based learning. The subjects of this study were 69 students who were divided into 2 classes, namely XI MIPA 3 as the control class using the direct instruction model and XI MIPA 2 as the experimental class using the problem based learning model. This research was conducted using a quasi-experimental design with the nonequivalent control group design. Data analysis techniques used Wilcoxon and descriptive tests. The results of this study indicate (1) the application of the problem based learning model of excretion system concept material has a significant effect on product cognitive learning outcomes in class XI students of SMAN 8 Banjarmasin with an Asymp.Sig value. (2-tailed) < 0.05, namely 0.000, (2) Learning outcomes which include cognitive processes with the application of problem based learning models are included in the good category, affective learning outcomes of character behavior (responsibility) are in the good category, behavioral affective learning outcomes character (politeness) in the very good category, as well as social behavior (cooperating) in the very good category and social behavior (contributing opinions) included in the good category, and psychomotor learning outcomes included in the good category.]]>
