This study aims to determine the effect of the digitalization-based Project-Based Learning (PjBL) model on the science literacy of fifth-grade students in Science and Social Studies (IPAS) learning on the topic of water cycle changes at SDN 3 Sekarteja. This study employed a quantitative quasi-experimental approach with a nonequivalent control group pretest-posttest design. The sample was selected using a purposive sampling technique, consisting of class V B as the experimental class (18 students) receiving the digitalization-based PjBL model with animated videos, and class V A as the control class (18 students) receiving conventional instruction. Data were gathered through a multiple-choice science literacy test and student activity observation sheets. The results showed that the experimental class achieved a higher posttest mean score of 75.18 compared to 57.79 in the control class, with average N-Gain scores of 0.50 and 0.33, respectively, both falling into the moderate category. Hypothesis testing on the posttest data yielded a significance value of 0.003 and on the N-Gain data of 0.025 (p<0.05), confirming a statistically significant difference between both classes. The pretest data indicated no significant initial difference between the groups (p=0.087), confirming that post-treatment achievements were attributable to the intervention. Consequently, the digitalization-based PjBL model is proven effective in enhancing elementary students' science literacy. ABSTRAK Penelitian ini bertujuan untuk mengetahui pengaruh model Project-Based Learning (PjBL) berbasis digitalisasi terhadap literasi sains siswa kelas V pada pembelajaran IPAS materi perubahan siklus air di SDN 3 Sekarteja. Penelitian menggunakan pendekatan kuantitatif jenis eksperimen semu (quasi-experiment) dengan desain nonequivalent control group pretest-posttest design. Sampel ditentukan melalui teknik purposive sampling, terdiri atas kelas V B sebagai kelas eksperimen (18 siswa) yang memperoleh model PjBL berbantuan media video animasi digital serta kelas V A sebagai kelas kontrol (18 siswa) dengan pembelajaran konvensional. Data dikumpulkan menggunakan instrumen tes literasi sains pilihan ganda serta lembar observasi aktivitas belajar siswa. Hasil penelitian menunjukkan nilai rata-rata post-test kelas eksperimen mencapai 75,18, sedangkan kelas kontrol memperoleh 57,79 dengan perolehan N-Gain masing-masing sebesar 0,50 dan 0,33 dalam kategori sedang. Uji hipotesis data post-test menghasilkan nilai signifikansi 0,003 dan pada data N-Gain sebesar 0,025 (p<0,05), yang membuktikan adanya perbedaan capaian yang signifikan antara kedua kelas. Data pretest kedua kelompok menunjukkan tidak ada perbedaan kemampuan awal yang signifikan (p=0,087), sehingga keunggulan akhir dapat diatribusikan pada perlakuan model. Dengan demikian, penerapan model PjBL berbasis digitalisasi terbukti efektif meningkatkan literasi sains siswa sekolah dasar secara nyata.
