This study aims to explain student learning activities and compare the learning outcomes of experimental and control classes on environmental pollution materials. The study was carried out at SMA N 1 Plumbon classes X MIPA 1 and X MIPA 2. This study's research design is an experimental design of this design in the form of a Pretest-Posttest Control Group Design. The data for this study was gathered through observations and tests. Because of the high category, the findings showed increased student learning activities, with an average score of 70.72%. There were substantial variations in student learning results in the experimental class, which used waste as a hidden curriculum and obtained an average score of N-Gain of 0.51 medium criteria, compared to the control class, which obtained an average score of N-Gain of 0.28 low criteria. The obtained significance value was 0.030, which is lower than 0.05, it is conclude that using waste as a hidden curriculum can increase student learning outcomes and activities.ABSTRAK: Penelitian ini bertujuan untuk mendeskripsikan aktivitas belajar siswa dan menganalisis perbedaan hasil belajar siswa kelas eksperimen dengan kelas kontrol pada materi pencemaran lingkungan.
