Abstract

ABSTRAK Perangkat pembelajaran mampu mewujudkan proses pembela jaran yang inovatif, inspiratif, menyenangkan serta menantang peser ta didik. Penelitian ini dilatarbelakangi oleh beberapa permasalahan diantaranya yaitu pada materi pencemaran lingkungan peserta didik masih tergolong rendah dan belum pernah diterapkannya pembelaja ran berbasis PBL-STEM di sekolah tersebut. Tujuan dari penelitian ini adalah untuk menganalisis prosedur pengembangan perangkat ajar, untuk menganalisis kelayakan perangkat ajar berbasis PBL STEM pada materi pencemaran lingkungan kelas X di SMA, dan un tuk menganalisis respon peserta didik dan pendidik terhadap pengembangan perangkat ajar berbasis PBL-STEM pada materi pencemaran lingkungan kelas X di SMA. Adapun penelitian ini menggunakan metode pengembangan R&D dengan model pengembangan 4D yaitu define, design, develop and disseminate. Instrumen pengumpulan data yang digunakan beru pa angket kepada ahli materi, ahli media, ahli bahasa, serta angket re spon peserta didik dan pendidik, wawancara dan dokumentasi. Hasil yang diperoleh dari validator ahli materi 1 dan ahli ma teri 2 mendapat nilai sebesar 96% dan 93% dengan kriteria sangat layak. Kemudian hasil presentase dari validator ahli media 1 dan ahli media 2 mendapat nilai sebesar 96% dan 98% dan ahli bahasa sebesar 96% dengan kriteria sangat layak. Sedangkan respon pendidik mendapat nilai sebesar 87% dengan kriteria sangat layak, dan hasil penilaian respon peserta didik dari hasil uji coba skala luas mendapat nilai sebesar 81% dan uji coba skala kecil mendapat nilai sebesar 85% dengan kriteria sangat layak. Maka dapat disimpulkan bahwa perangkat ajar berbasis PBL-STEM pada materi pencemaran ling kungan kelas X di SMA ini sangat layak digunakan dalam proses pembelajaran Biologi.

This research is motivated by several problems, including that in the material on envi ronmental pollution, students are still relatively low and PBL-STEM based learning has never been implemented in the school. The pur pose of this study is to analyze the procedure for developing teaching devices, to analyze the feasibility of PBL-STEM-based teaching devic es on environmental pollution material for class X in high school, and to analyze the responses of students and educators to the development of PBL-STEM-based teaching devices on environmental pollution ma terial for class X in high school. This study uses the R&D development method with the 4D de velopment model, namely define, design, develop and disseminate. The data collection instruments used are questionnaires to material ex perts, media experts, language experts, as well as student and educa tor response questionnaires, interviews and documentation. The results obtained from the validator of material expert 1 and material expert 2 got a score of 96% and 93% with very feasible criteria. Then the percentage results from the validator of media ex pert 1 and media expert 2 got a score of 96% and 98% and the lan guage expert 96% with very feasible criteria. While the educator's response got a score of 87% with very feasible criteria, and the results of the assessment of student responses from the results of large-scale trials got a score of 81% and small-scale trials got a score of 85% with very feasible criteria. So it can be concluded that the PBL-STEM based teaching device on environmental pollution material for class X in this high school is very feasible to use in the Biology learn ing process. Keywords: Environmental Pollution, PBL-STEM, Teaching Tools.
