PENGARUH MODEL PROJECT BASED LEARNING PADA MATERI VARIASI ARAH DAN SUMBER CAHAYA MATA PELAJARAN FOTOGRAFI UNTUK MENINGKATKAN HASIL BELAJAR SISWA KELAS XI DKV DI SMKN 13 SURABAYA

THE EFFECT OF THE PROJECT-BASED LEARNING MODEL ON THE TOPIC OF VARIATIONS IN LIGHT DIRECTION AND SOURCES IN THE PHOTOGRAPHY COURSE ON IMPROVING THE LEARNING OUTCOMES OF 11TH-GRADE VISUAL COMMUNICATION DESIGN STUDENTS AT SMKN 13 SURABAYA

Tujuan penelitian ini adalah untuk mengetahui pengaruh penerapan model Project Based Learning (PjBL) terhadap hasil belajar siswa pada materi variasi arah dan sumber cahaya mata pelajaran Fotografi kelas XI Desain Komunikasi Visual (DKV) di SMKN 13 Surabaya. Penelitian ini dilatarbelakangi oleh rendahnya hasil belajar siswa yang masih berada di bawah nilai ketuntasan minimal. Penelitian menggunakan pendekatan kuantitatif dengan metode eksperimen dan desain Posttest-Only Control Group Design. Penelitian dilaksanakan di SMKN 13 Surabaya dengan subjek siswa kelas XI DKV. Data dikumpulkan melalui penilaian proyek fotografi menggunakan instrumen rubrik penilaian proyek. Analisis data dilakukan menggunakan uji normalitas, uji homogenitas, dan uji independent sample t-test. Hasil penelitian menunjukkan bahwa data berdistribusi normal dan homogen. Uji hipotesis memperoleh nilai signifikansi sebesar 0,010 < 0,05 sehingga hipotesis alternatif diterima. Rata-rata hasil belajar kelas eksperimen sebesar 82,50 lebih tinggi dibandingkan kelas kontrol sebesar 76,88. Dengan demikian, penerapan model Project Based Learning (PjBL) berpengaruh signifikan terhadap peningkatan hasil belajar siswa pada materi variasi arah dan sumber cahaya. Model PjBL disarankan sebagai alternatif pembelajaran pada mata pelajaran yang berorientasi pada praktik dan dapat dikembangkan pada materi maupun jenjang pendidikan yang berbeda.

The purpose of this study is to determine whether the implementation of the Project-Based Learning (PjBL) model in the Photography course for eleventh-grade Visual Communication Design (VCD) students at SMKN 13 Surabaya can improve students' learning outcomes regarding variations in light direction and light sources. Low student learning outcomes, as indicated by the average initial test scores of 68.96 in Class XI DKV 1 and 76.06 in Class XI DKV 2, which were below or equal to the minimum passing criterion of 76, served as the rationale for conducting this study. This study employed a quantitative approach using an experimental method with a Posttest-Only Control Group Design. The PjBL model was implemented in the experimental class, while the control class received conventional instruction without the PjBL model. Data were collected through product photography project assessments and analyzed using normality, homogeneity, and independent samples t-tests. The results showed that the data were normally distributed and homogeneous. The hypothesis test produced a significance value of 0.010 (< 0.05), indicating that the alternative hypothesis (Ha) was accepted. The experimental class achieved a higher mean score (82.50) than the control class (76.88). It can be concluded that the implementation of the Project-Based Learning (PjBL) model has a significant positive effect on students' learning outcomes in the Photography course, particularly on the topic of variations in light direction and light sources. Therefore, the PjBL model is recommended as an alternative instructional model for practice-oriented subjects and may be further implemented and investigated in different learning materials and educational settings.
