Oleh karena itu, peningkatan hasil belajar menjadi aspek yang penting untuk memastikan siswa dapat mengaitkan konsep-konsep pembelajaran dengan permasalahan di lingkungan sekitar. Penelitian ini bertujuan untuk mengetahui pengaruh penerapan model pembelajaran Dilemma-STEAM terhadap hasil belajar siswa pada materi Pencemaran Lingkungan. Model pembelajaran Dilemma-STEAM merupakan perpaduan antara dilemma stories dan pendekatan STEAM (Science, Technology, Engineering, Art, Mathematics). Penelitian ini merupakan Quasi-experiment dengan desain penelitian one group pretest-posttest, yang dilaksanakan pada siswa kelas X-2 di SMA Negeri 5 Kabupaten Tangerang. Instrumen yang digunakan meliputi soal pretest dan posttest, modul ajar, LKPD, serta lembar observasi. Data yang diperoleh dianalisis secara deskriptif dengan menggunakan Microsoft Excel dan analisis inferensial dengan menggunakan SPSS 26.0. Hasil analisis menunjukkan bahwa adanya perbedaan sebelum dan setelah diterapkannya model pembelajaran Dilemma-STEAM terhadap hasil belajar siswa. Hasil ini dibuktikan pada hasil uji hipotesis yang memperoleh nilai sig. (2-tailed) sebesar 0.000 < 0.05. Dengan demikian H0 ditolak dan H1 diterima. Temuan ini diperkuat dengan peningkatan hasil rata-rata pretest 29.759 menjadi hasil rata-rata posttest 80.482. Dengan demikian, model pembelajaran Dilemma-STEAM efektif dalam meningkatkan hasil belajar siswa pada materi Pencemaran Lingkungan. abstract: Learning outcomes are one of the important indicators in evaluating the success of the learning process because they reflect students' level of understanding of the material, mastery of skills, and ability to apply knowledge in real life. Therefore, improving learning outcomes is an important aspect to ensure that students can relate learning concepts to problems in their surroundings. This study aims to determine the effect of applying the Dilemma-STEAM learning model on students' learning outcomes in the subject of Environmental Pollution. The Dilemma-STEAM learning model is a combination of dilemma stories and the STEAM approach (Science, Technology, Engineering, Art, Mathematics). This study is a quasi-experiment with a one-group pretest-posttest design, conducted on students in class X-2 at SMA Negeri 5 Kabupaten Tangerang. The instruments used include pretest and posttest questions, teaching modules, worksheets, and observation sheets. The data obtained were analyzed descriptively using Microsoft Excel and inferentially using SPSS 26.0. The analysis results showed that there was a difference before and after the implementation of the Dilemma-STEAM learning model on student learning outcomes. This result was proven by the hypothesis test, which obtained a sig. (2-tailed) of 0.000 < 0.05. Thus, H0 was rejected and H1 was accepted. This finding was reinforced by the increase in the average pretest score from 29.759 to the average posttest score of 80.482. Therefore, the Dilemma-STEAM learning model is effective in improving students' learning outcomes on the topic of Environmental Pollution date: 2025 date_type: published pages: 175 institution: UNIVERSITAS SULTAN AGENG TIRTAYASA department: PENDIDIKAN KIMIA thesis_type: sarjana thesis_name: sarjana citation: AMALIA, FIRDA (2025) PENERAPAN MODEL PEMBELAJARAN DILEMMA-STEAM UNTUK MENINGKATKAN HASIL BELAJAR SISWA PADA MATERI PENCEMARAN LINGKUNGAN.
