Pengembangan Perangkat Perkuliahan Berbasis Problem Based Learning Pada Materi Bioremidiasi Untuk Memfasilitasi Keterampilan Pemecahan Masalah

Development of Lecture Devices Based on Problem Based Learning on the Bioremidiation Material to Facilitate Problem Solving Skills

Perangkat perkulihaan yang dikembangkan merupakan perangkat perkuliahan berbasis PBL yang dapat memfasilitasi mahasiswa dalam meningkatkan keterampilan pemecahan masalah melalui studi reverensi dan studi kasus pada masalah bioremidiasi yang diberikan. Tujuan penelitian pengembangan adalah menghasilkan perangkat perkuliahan berbasis PBL pada materi bioremidiasi yang dapat memfasilitasi keterampilan pemecahan masalah. Model yang digunakan dalam penelitian pengembangan yaitu modifikasi ADDIE (Analyze, Design, Development, Implement, Evaluate ) dengan rancangan penelitian Prettes and Posttest Design. Data diperoleh dengan teknik validasi, teknik observasi dan teknik tes. Produk yang telah dikembangkan divalidasi oleh ahli materi dan ahli media. Hasil validasi berupa skor yang dianalisis secara kuantitatif, sedangkan komentar dan saran dianalisis secara kualitatif. Uji keefektifan dilakukan dengan menerapkan produk yang dikembangkan menggunakan rancangan  one group prettest and posttest design. Subjek uji coba penelitian yaitu 20 mahasiswa S1 Biologi di Universitas Negeri Surabaya dengan sampel yang di tentukan secara purposif. Waktu pelaksanaan uji coba pada bulan Maret 2020. Hasil penelitian meliputi validitas, kepraktisan, dan kefektifan. Hasil validitas sebagai berkut: RPS 3,36; SAP 3,34 dan LKM 3,36, sedangkan kepraktisan dengan rata-rata skor 4 serta keefektifan dengan kenaikan Ngainnya 0,78. Peningkatan hasil belajar dianalisis secara deskriptif dengan Ngain score. Berdasarkan uraian di atas dapat disimpulkan bahwa perangkat perkuliahan valid, praktis, dan efektif sehingga dapat memfasilitasi keterampilan pemecahan masalah.

The lecture device developed is a PBL-based lecture tool that can facilitate students in improving problem solving skills through reference studies and case studies on given bioremediation problems. The purpose of development research is to produce PBL-based lecture tools on bioremediation materials that can facilitate problem solving skills. The model used in development research is the modification of ADDIE (Analyze, Design, Development, Implement, Evaluate) with the research design Prettes and Posttest Design. Data obtained by validation techniques, observation techniques and test techniques. Products that have been developed are validated by material experts and media experts. The results of the validation are scores that are analyzed quantitatively, while comments and suggestions are analyzed qualitatively. The effectiveness test is done by implementing a product that was developed using a one group prettest and posttest design. The subjects of the research trial were 20 undergraduate biology students at Surabaya State University with the sample determined purposively. The time of the trial run in March 2020. The results of the study include validity, practicality, and effectiveness. The results of validity as follows: RPS 3.36; SAP 3.34 and LKM 3.36, while practicality with an average score of 4 and effectiveness with an increase of 0.78 Ngainnya. Improved learning outcomes were analyzed descriptively with Ngain score. Based on the description above it can be concluded that the lecture devices are valid, practical, and effective so that they can facilitate problem solving skills.
