<![CDATA[This study was motivated by the low level of student engagement in Islamic Religious Education (PAI) learning, which has resulted in suboptimal learning outcomes. The Project Based Learning (PjBL) model is considered an innovative learning approach that promotes active student participation through project-based activities. This study aimed to examine the effect of the PjBL model on the learning outcomes of Grade X students in Islamic Religious Education at SMA Al Hadi Bandung City. A quantitative approach with a quasi-experimental method employing a nonequivalent control group design was used. The sample consisted of 28 students in the experimental class and 27 students in the control class. Data were collected through observations, interviews, documentation, pretests, posttests, and questionnaires. The data were analyzed using normality and homogeneity tests, followed by an independent sample t-test. The findings revealed that the average pretest scores were 72.10 for the experimental class and 74.51 for the control class. Following the implementation of the PjBL model, the average posttest scores increased to 90.04 and 82.81, respectively. The hypothesis testing produced a significance value of 0.000 (<0.05), indicating that the implementation of the Project Based Learning model had a statistically significant effect on students' learning outcomes in Islamic Religious Education. These findings suggest that the PjBL model can serve as an effective student-centered learning approach to improve learning outcomes in Islamic Religious Education. Penelitian ini dilatarbelakangi oleh rendahnya keterlibatan siswa dalam pembelajaran Pendidikan Agama Islam (PAI) yang berdampak pada belum optimalnya hasil belajar. Model Project Based Learning (PjBL) dipandang sebagai salah satu alternatif pembelajaran yang mampu meningkatkan partisipasi aktif dan hasil belajar siswa melalui kegiatan berbasis proyek. Penelitian ini bertujuan untuk menganalisis pengaruh penerapan model PjBL terhadap hasil belajar PAI siswa kelas X di SMA Al Hadi Kota Bandung. Penelitian menggunakan pendekatan kuantitatif dengan metode quasi experiment dan desain nonequivalent control group design. Sampel penelitian terdiri atas 28 siswa pada kelas eksperimen dan 27 siswa pada kelas kontrol. Pengumpulan data dilakukan melalui observasi, wawancara, dokumentasi, tes (pretest dan posttest), serta angket. Analisis data menggunakan uji normalitas, uji homogenitas, dan independent sample t-test. Hasil penelitian menunjukkan bahwa rata-rata nilai pretest kelas eksperimen sebesar 72,10 dan kelas kontrol sebesar 74,51. Setelah penerapan model PjBL, rata-rata nilai posttest meningkat menjadi 90,04 pada kelas eksperimen dan 82,81 pada kelas kontrol. Hasil uji hipotesis menunjukkan nilai signifikansi sebesar 0,000 (<0,05), sehingga terdapat pengaruh yang signifikan antara penerapan model Project Based Learning terhadap hasil belajar PAI siswa kelas X di SMA Al Hadi Kota Bandung. Temuan ini menunjukkan bahwa model PjBL dapat menjadi alternatif pembelajaran yang efektif dalam meningkatkan hasil belajar PAI melalui pembelajaran yang berpusat pada peserta didik.]]>
