Abstract

ABSTRAK Kemampuan berpikir kreatif dan kemampuan komunikasi merupakan dua keterampilan abad ke-21 yang sangat penting bagi peserta didik dalam menghadapi tantangan global. Berdasarkan hasil pra penelitian di MAN 1 Bandar Lampung, kemampuan berpikir kreatif siswa kelas X hanya mencapai kategori cukup kreatif, sedangkan kemampuan komunikasi berada pada kategori kurang. Kondisi ini menunjukkan bahwa model pembelajaran yang digunakan belum mampu mengoptimalkan kedua kemampuan tersebut secara bersamaan, sehingga diperlukan model pembelajaran Project Based Learning berbasis Pendekatan Saintifik. Penelitian ini bertujuan mengetahui pengaruh model pembelajaran PjBL berbasis Pendekatan Saintifik terhadap kemampuan berfikir kreatif dan kemampuan komunikasi siswa kelas X pada materi bioteknologi. Metode yang digunakan adalah penelitian kuantitatif dengan desain Quasy Experiment tipe Nonequivalent Control Group Design. Teknik pengumpulan data menggunakan tes, observasi, dan dokumentasi, dengan populasi peserta didik kelas X yang diambil melalui Teknik Cluster Random Sampling, terdiri atas kelas eksperimen (X.7, 33 peserta didik) dan kelas kontrol (X.3, 32 peserta didik). Instrumen diuji dengan validitas Corelation Pearson Product Moment dan reliabilitas koefisien Alpha Cronbach, serta uji prasyarat analisis berupa uji normalitas Klomogrov Sminov dan uji homogenitas Test Of Homogenity Of Varience, yang keduanya menunjukkan hasil berdistribusi normal dan bersifat homogen. Hasil analisis data menggunakan uji t (independent sample t�test) diperoleh nilai Sig sebesar 0,00 atau ≤ 0,05, yang berarti model pembelajaran PjBL berbasis Pendekatan Saintifik berpengaruh terhadap kemampuan berfikir kreatif peserta didik, serta nilai kemampuan komunikasi kelas eksperimen yang lebih tinggi dibandingkan kelas kontrol. ABSTRACT Creative thinking and communication skills are two crucial 21st-century skills for students facing global challenges. Preliminary research at MAN 1 Bandar Lampung revealed that the creative thinking skills of Grade X students fell into the "moderately creative" category, while their communication skills were rated as "poor." This situation indicates that the current learning model has not effectively optimized both skills simultaneously; therefore, a Project-Based Learning model incorporating a scientific approach is required. This study aims to determine the effect of a Scientific Approach-based Project-Based Learning (PjBL) model on the creative thinking and communication skills of Grade X students regarding the topic of biotechnology. A quantitative research method was employed using a quasi-experimental design—specifically, the Nonequivalent Control Group Design. Data collection involved tests, observation, and documentation, with the study population consisting of Grade X students selected via cluster random sampling: an experimental class (X.7, 33 students) and a control class (X.3, 32 students). The instruments were validated using the Pearson Product-Moment Correlation and tested for reliability using Cronbach's Alpha coefficient; prerequisite analysis included the Kolmogorov-Smirnov normality test and the Test of Homogeneity of Variance, both of which indicated that the data were normally distributed and homogeneous. Data analysis using the independent sample t-test yielded a significance (Sig.) value of 0.00 (≤ 0.05), indicating that the PjBL learning model based on the Scientific Approach influences students' creative thinking skills; additionally, the experimental class demonstrated higher communication skill scores compared to the control class.
