Abstract

Penelitian ini bertujuan untuk mencari pengaruh model Project based learning melalui Praktikum Fermentasi terhadap Pemahaman Konsep Bioteknologi Siswa Kelas XII Madrasah Aliyah Pondok Pesantren Modern Raudhatul Fikri Sei Cina Tahun Pembelajaran 2026/2027. Penelitian ini menggunakan pendekatan kuantitatif dengan metode quasi experiment dan desain Nonequivalent Control Group Design. Sampel penelitian berjumlah 36 siswa yang terdiri atas 18 siswa kelas eksperimen dan 18 siswa kelas kontrol. Kelas eksperimen diberikan pembelajaran menggunakan model Project based learning melalui praktikum fermentasi, sedangkan kelas kontrol diberikan pembelajaran konvensional. Pengumpulan data dilakukan menggunakan tes pemahaman konsep berupa 30 soal pilihan ganda yang diberikan sebagai pretest dan posttest. Data dianalisis menggunakan uji normalitas, uji homogenitas, uji N-Gain, dan Independent Samples t-Test dengan bantuan SPSS. Hasil penelitian menunjukkan bahwa terdapat peningkatan pemahaman konsep yang lebih tinggi pada kelas eksperimen. Rata-rata N-Gain kelas eksperimen sebesar 86,99% dengan kategori tinggi, sedangkan kelas kontrol sebesar 43,71% dengan kategori rendah. Hasil uji hipotesis menggunakan Independent Samples t Test menunjukkan nilai signifikansi sebesar 0,000 < 0,05, sehingga H₀ ditolak dan H₁ diterima. Rata-rata hasil tes kelas eksperimen sebesar 93,78, sedangkan kelas kontrol sebesar 74,00, dengan selisih rata-rata sebesar 19,78 poin. Dengan demikian, dapat disimpulkan bahwa terdapat pengaruh yang signifikan dan positif dari penerapan model Project based learning melalui praktikum fermentasi terhadap pemahaman konsep bioteknologi siswa kelas XII Madrasah Aliyah Pondok Pesantren Modern Raudhatul Fikri Sei Cina Tahun Pembelajaran 2026/2027. Kata kunci : Project Based Learning, Praktikum Fermentasi, Pemahaman Konsep, Bioteknologi. ================================================================================================ This study aimed to determine the effect of the model through fermentation practicum on students’ understanding of biotechnology concepts in Grade XII at Madrasah Aliyah Pondok Pesantren Modern Raudhatul Fikri Sei Cina during the 2026/2027 academic year. This research employed a quantitative approach using a quasi-experimental method with a Nonequivalent Control Group Design. The research sample consisted of 36 students, comprising 18 students in the experimental class and 18 students in the control class. The experimental class was taught using the model through fermentation practicum, while the control class was taught using conventional learning. Data were collected using a concept-understanding test consisting of 30 multiple-choice questions administered as a pretest and posttest. The data were analyzed using normality test, homogeneity test, N-Gain test, and Independent Samples t-Test with the assistance of SPSS. The results showed that the improvement in students’ understanding of biotechnology concepts was higher in the experimental class. The average N-Gain score of the experimental class was 86.99%, categorized as high, while the control class obtained an average N-Gain score of 43.71%, categorized as low. The hypothesis test using the Independent Samples t-Test resulted in a significance value of 0.000 < 0.05, indicating that H₀ was rejected and H₁ was accepted. The experimental class obtained a mean posttest score of 93.78, while the control class obtained a mean posttest score of 74.00, with a mean difference of 19.78 points. Therefore, it can be concluded that the implementation of the model through fermentation practicum has a significant and positive effect on students’ understanding of biotechnology concepts in Grade XII at Madrasah Aliyah Pondok Pesantren Modern Raudhatul Fikri Sei Cina during the 2026/2027 academic year. Keywords: Project-Based Learning, Fermentation Practicum, Concept Understanding, Biotechnology.
