IMPLEMENTASI PROBLEM BASED LEARNING PADA MATERI PENCEMARAN LINGKUNGAN UNTUK MENINGKATKAN KETERAMPILAN SISWA DALAM MEMECAHKAN MASALAH 

IMPLEMENTATION OF PROBLEM BASED LEARNING ON ENVIRONMENTAL POLLUTION MATERIAL TO IMPROVE STUDENTS' PROBLEM SOLVING SKILLS 

    Penelitian ini bertujuan untuk mendeskripsikan keterampilan pemecahan masalah, keterlaksanaan pembelajaran, dan respons siswa setelah penerapan model Problem Based Learning (PBL) pada materi pencemaran lingkungan. Penelitian ini menggunakan desain one group pretest-posttest dan melibatkan 30 siswa kelas VII A di UPT SMPN 10 Gresik. Data dikumpulkan melalui tes, observasi, dan angket. Hasil penelitian menunjukkan peningkatan keterampilan pemecahan masalah dengan nilai N-Gain sebesar 0,65 (kategori sedang), keterlaksanaan pembelajaran mencapai 100% (kategori sangat baik), dan respons siswa terhadap pembelajaran sebesar 87% (kategori sangat baik). Berdasarkan temuan tersebut, disimpulkan bahwa penerapan model PBL pada materi pencemaran lingkungan dapat meningkatkan keterampilan pemecahan masalah siswa.

This study aims to describe problem solving skills, learning implementation, and student responses after the application of the Problem Based Learning (PBL) model on environmental pollution material. This study used a one group pretest-posttest design and involved 30 students of class VII A at UPT SMPN 10 Gresik. Data were collected through tests, observations, and questionnaires. The results showed an increase in problem solving skills with an N-Gain value of 0.65 (medium category), learning implementation reached 100% (very good category), and student response to learning was 87% (very good category). Based on these findings, it is concluded that the application of the PBL model on environmental pollution material can improve students' problem solving skills.
