<![CDATA[ABSTRACT This study aims to determine the effect of the Problem Based Learning model on students' creativity and collaboration in science learning. The study is motivated by the importance of developing 21st-century skills, particularly creative thinking and collaboration, which still need improvement in classroom learning. The Problem Based Learning model is applied because it uses contextual problems as the starting point of learning, encouraging students to think creatively, discuss ideas, and collaborate to find solutions. This research employed a quantitative approach using a quasi-experimental design with a posttest only control design. The sample consisted of 23 students in the experimental class and 24 students in the control class selected through random sampling. The research instruments included a creativity test, a collaboration questionnaire, and a collaboration observation sheet. The data analysis results showed that the Independent Sample t-test for creativity obtained a sig. (2-tailed) value of 0.000 < 0.05 and the collaboration test also obtained a sig. (2-tailed) value of 0.000 < 0.05. In addition, the MANOVA test showed a significance value of 0.000 < 0.05, indicating that the Problem Based Learning model simultaneously affects students' creativity and collaboration. These findings indicate that the Problem Based Learning model is effective in improving students' creativity and collaboration in science learning. ABSTRAK Penelitian ini bertujuan untuk membuktikan pengaruh model Problem Based Learning terhadap kreativitas dan kolaborasi siswa dalam pembelajaran IPA. Penelitian ini dilatarbelakangi oleh pentingnya pengembangan keterampilan abad ke-21, khususnya kemampuan berpikir kreatif dan bekerja sama yang masih perlu ditingkatkan dalam proses pembelajaran di sekolah. Model Problem Based Learning digunakan karena menempatkan masalah kontekstual sebagai titik awal pembelajaran sehingga mendorong siswa berpikir kreatif, berdiskusi, dan berkolaborasi dalam menemukan solusi. Penelitian ini menggunakan pendekatan kuantitatif dengan desain eksperimen semu (Quasi-Experimental Design) tipe posttest only control design. Sampel penelitian terdiri dari 23 siswa pada kelas eksperimen dan 24 siswa pada kelas kontrol yang dipilih melalui teknik random sampling. Instrumen penelitian meliputi tes kreativitas, angket kolaborasi, dan lembar observasi kolaborasi. Hasil analisis data menunjukkan bahwa uji Independent Sample t-test pada kreativitas memperoleh nilai sig. (2-tailed) 0,000 < 0,05 dan pada kolaborasi juga memperoleh nilai sig. (2-tailed) 0,000 < 0,05. Selain itu, uji MANOVA menunjukkan nilai signifikansi 0,000 < 0,05 yang menegaskan bahwa model Problem Based Learning secara simultan berpengaruh terhadap kreativitas dan kolaborasi siswa. Temuan ini menunjukkan bahwa model Problem Based Learning efektif meningkatkan kreativitas dan kemampuan kolaborasi siswa dalam pembelajaran IPA.]]>
