This study aims to examine the effect of the green education-based Project-Based Learning (PjBL) model on students' collaboration skills and environmental awareness in the science subject (IPAS) at SDN 169 Pekanbaru. A quasi-experimental design with a non-equivalent control group pretest-posttest design was employed, involving 36 students in the experimental class (Class IIID) and 31 students in the control class (Class IIIC). The experimental group received instruction using the PjBL model integrated with green education principles, while the control group received conventional instruction. Data were collected through an observation rubric for collaboration skills and a questionnaire for environmental awareness attitudes, then analyzed using IBM SPSS Statistics 25. The results indicated a significant improvement in collaboration skills in the experimental class, with a posttest mean of 84.14 (N-Gain = 0.753, high category), compared to the control class mean of 68.42 (N-Gain = 0.488, medium category). An independent sample t-test yielded t = 9.856 with p = 0.000 < 0.05, and Cohen's d = 2.48, indicating a very large effect size. For environmental awareness, the experimental class achieved an N-Gain of 0.665, compared to the control class N-Gain of 0.599. Although the between-group posttest difference was not statistically significant (p = 0.128), the within-group improvement was significant (t = -19.62; p = 0.000). These findings suggest that the green education-based PjBL model significantly improves collaboration skills and meaningfully fosters environmental awareness among elementary school students. Abstrak Penelitian ini bertujuan untuk mengkaji implementasi model pembelajaran Project-Based Learning (PjBL) berbasis green education terhadap keterampilan kolaborasi dan sikap peduli lingkungan siswa pada mata pelajaran IPAS di SDN 169 Pekanbaru. Penelitian menggunakan desain kuasi-eksperimen dengan non-equivalent control group pretest-posttest design, melibatkan 36 siswa kelas eksperimen (Kelas IIID) dan 31 siswa kelas kontrol (Kelas IIIC). Kelompok eksperimen memperoleh pembelajaran dengan model PjBL terintegrasi prinsip green education, sedangkan kelompok kontrol menggunakan pembelajaran konvensional. Data dikumpulkan melalui lembar observasi keterampilan kolaborasi dan angket sikap peduli lingkungan, kemudian dianalisis menggunakan IBM SPSS Statistics 25. Hasil penelitian menunjukkan peningkatan signifikan keterampilan kolaborasi pada kelas eksperimen dengan rata-rata posttest 84,14 (N-Gain = 0,753, kategori tinggi), dibandingkan kelas kontrol 68,42 (N-Gain = 0,488, kategori sedang). Uji independent sample t-test menghasilkan t = 9,856 dengan p = 0,000 < 0,05 dan Cohen's d = 2,48 (efek sangat besar). Untuk sikap peduli lingkungan, N-Gain kelas eksperimen sebesar 0,665 melampaui kelas kontrol 0,599; meskipun perbedaan antarkelompok belum signifikan secara statistik (p = 0,128), peningkatan dalam kelompok eksperimen terbukti sangat signifikan (t = -19,62; p = 0,000). Temuan ini menunjukkan bahwa model PjBL berbasis green education secara signifikan meningkatkan keterampilan kolaborasi dan secara bermakna menumbuhkan sikap peduli lingkungan siswa sekolah dasar.
