Abstract

ABSTRAK Integritas akademik yang rendah, seperti menyontek dan plagiarisme, masih menjadi persoalan di dunia pendidikan dan berdampak pada rendahnya tanggung jawab serta kejujuran peserta didik dalam belajar. Kondisi ini tidak hanya memengaruhi sikap belajar, tetapi juga menghambat pengembangan keterampilan esensial abad ke 21, yakni kemampuan berpikir kreatif dan komunikasi matematis. Keterampilan tersebut menuntut peserta didik untuk mampu menghasilkan ide-ide baru sekaligus menyajikannya secara runtut, logis, dan mudah dipahami.Namun, pra-penelitian menunjukkan bahwa peserta didik SMP N 8 TBB masih mengalami kesulitan dalam menghasilkan ide-ide baru dan menyampaikan gagasan secara runtut. Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran Project Based Blended Learning dan integritas akademik terhadap kemampuan berpikir kreatif dan komunikasi matematis. Penelitian menggunakan metode quasi experiment dengan posttest-only control group design melibatkan kelas VIII-E sebagai eksperimen (PjB2L) dan VIII-F sebagai kontrol (Direct Instruction). Instrumen berupa tes dan angket, dengan analisis data menggunakan Two Way MANOVA. Hasil penelitian menunjukkan bahwa PjB2L berpengaruh signifikan terhadap kemampuan berpikir kreatif dan komunikasi matematis dibandingkan dengan Direct Instruction, karena mendorong peserta didik aktif dalam proyek, mengidentifikasi masalah, merancang solusi, serta mengkomunikasikan hasil kerja kelompok, sedangkan integritas akademik memberikan kontribusi besar karena peserta didik berintegritas tinggi cenderung disiplin, jujur, dan konsisten. Analisis Partial Eta Squared menunjukkan bahwa pengaruh utama model pembelajaran dan integritas akademik lebih besar dibanding interaksinya, karena adanya tumpang tindih pengaruh antarvariabel. Dengan demikian, PjB2L yang didukung integritas akademik terbukti berpengaruh terhadap kemampuan berpikir kreatif dan komunikasi matematis peserta didik. Kata kunci: Berpikir kreatif matematis, komunikasi matematis, Project Based Blended Learning, integritas akademik ii ABSTRACT Low academic integrity, such as cheating and plagiarism, remains a problem in education and impacts students' low level of responsibility and honesty in learning. This condition not only affects learning attitudes but also hinders the development of essential 21st-century skills, namely creative thinking and mathematical communication skills. These skills require students to be able to generate new ideas and present them in a coherent, logical, and understandable manner. However, pre-research shows that students at SMP N 8 TBB still experience difficulties in generating new ideas and conveying ideas coherently. This study aims to determine the effect of the Project-Based Blended Learning model and academic integrity on creative thinking and mathematical communication skills. The study used a quasi experimental method with a posttest-only control group design, involving class VIII-E as the experimental class (PjB2L) and class VIII F as the control class (Direct Instruction). The instruments were tests and questionnaires, with data analysis using Two-Way MANOVA. The results of the study showed that PjB2L had a significant effect on creative thinking and mathematical communication skills compared to Direct Instruction, because it encouraged students to be active in projects, identify problems, design solutions, and communicate the results of group work, while academic integrity made a major contribution because students with high integrity tended to be disciplined, honest, and consistent. Partial Eta Squared analysis showed that the main effect of the learning model and academic integrity was greater than the interaction, due to the overlapping influence between variables. Thus, PjB2L supported by academic integrity was proven to have an effect on students' creative thinking and mathematical communication skills. Keywords: Creative mathematical thinking, mathematical communication, Project Based Blended Learning, academic integrity
