Abstract
Penelitian ini bertujuan untuk menganalisis pengaruh penerapan praktikum isolasi DNA dengan teknik Kitchen Preparation terhadap keterampilan proses sains (KPS) dan penguasaan konsep siswa pada topik substansi hereditas. Penelitian ini menggunakan metode eksperimen dengan desain quasi-experimental menggunakan control group pretest-posttest. Partisipan penelitian adalah siswa kelas XI madrasah aliyah di Banda Aceh tahun ajaran 2023/2024 yang dipilih secara purposive sampling. Kelas eksperimen diberikan perlakuan berupa praktikum Kitchen Preparation, sementara kelas kontrol menggunakan modul pembelajaran dan media visual seperti video dan simulasi virtual lab. Hasil uji non-parametrik Mann-Whitney U menunjukkan tidak ada perbedaan signifikan dalam skor posttest keterampilan proses sains antara kelas eksperimen dan kontrol (p-value = 0,41 > 0,05). Selain itu, uji Mann-Whitney U pada penguasaan konsep menunjukkan adanya perbedaan signifikan antara kelas eksperimen dan kontrol (p-value = 0,01 < 0,05). Kelas eksperimen menunjukkan peningkatan penguasaan konsep yang lebih baik, dengan persentase siswa yang mencapai kategori n-gain tinggi dan sedang lebih besar dibandingkan kelas kontrol. Analisis korelasi Spearman menunjukkan hubungan positif yang kuat antara KPS dan penguasaan konsep di kelas eksperimen (koefisien korelasi = 0.639), lebih tinggi dibandingkan dengan kelas kontrol (koefisien korelasi = 0.479). Dengan demikian, meskipun tidak memberikan pengaruh yang signifikan terhadap peningkatan keterampilan proses sains antara kedua kelas, metode Kitchen Preparation terbukti lebih berpengaruh dalam meningkatkan penguasaan konsep siswa. Hasil ini mendukung penggunaan Kitchen Preparation sebagai pendekatan praktikum yang lebih unggul dalam pembelajaran topik hereditas di tingkat pendidikan menengah. This study aimed to analyze the impact of applying the DNA isolation practicum using the Kitchen Preparation technique on students' science process skills (SPS) and concept mastery on the topic of hereditary substances. The research employed an experimental method with a quasi-experimental design using a control group pretest-posttest approach. The research participants were students from grade XI of a Madrasah Aliyah in Banda Aceh for the academic year 2023/2024, selected through purposive sampling. The experimental class received treatment in the form of a Kitchen Preparation practicum, while the control class used learning modules and visual media such as videos and virtual lab simulations. The results of the Mann-Whitney U non-parametric test showed no significant difference in the posttest scores of science process skills between the experimental and control classes (p-value = 0.41 > 0.05). However, the N-Gain analysis revealed that the experimental class had a higher percentage of students reaching the high and medium N-Gain categories compared to the control class, indicating that the Kitchen Preparation method had a greater impact on improving students' science process skills. Additionally, the Mann-Whitney U test on concept mastery showed a significant difference between the experimental and control classes (p-value = 0.01 < 0.05). The experimental class demonstrated better improvement in concept mastery, with a higher percentage of students reaching the high and medium N-Gain categories compared to the control class. Spearman's correlation analysis showed a strong positive relationship between SPS and concept mastery in the experimental class (correlation coefficient = 0.639), which was higher than in the control class (correlation coefficient = 0.479). Therefore, although it did not significantly affect the improvement of science process skills between the two classes, the Kitchen Preparation method proved to have a greater impact on enhancing students' concept mastery. These results support the use of Kitchen Preparation as a superior practicum approach in teaching the topic of heredity at the secondary education level.
