Abstract
Penelitian ini bertujuan untuk mengetahui keefektifan LKPD berbasis proyek pengolahan limbah kulit buah naga dalam meningkatkan keterampilan berpikir kritis dan self-regulated learning peserta didik pada materi alternative energy. Penelitian dilakukan di SMAN 1 Sumberejo menggunakan metode quasi experiment dengan desain pretest-posttest nonequivalent group design. Sampel penelitian terdiri dari kelas X E1 dan X E4 dengan jumlah 66 peserta didik. Instrumen yang digunakan berupa soal esai keterampilan berpikir kritis dan angket self-regulated learning. Hasil penelitian menunjukkan rata-rata N-Gain keterampilan berpikir kritis sebesar 0,65 pada kelas eksperimen 1 dan 0,67 pada kelas eksperimen 2. Uji paired sample t-test menunjukkan nilai signifikansi 0,001 < 0,05 yang berarti terjadi peningkatan keterampilan berpikir kritis peserta didik. Sementara itu, uji One Way ANOVA menunjukkan tidak terdapat perbedaan peningkatan berdasarkan kemampuan awal peserta didik (0,165 > 0,05). Hasil angket self-regulated learning memperoleh persentase 89,93% dan 92,81% dengan kategori sangat tinggi. Selain itu, uji korelasi bivariat menunjukkan adanya hubungan positif antara keterampilan berpikir kritis dan self-regulated learning dengan nilai Pearson correlation sebesar 0,50 berkategori sedang. Dengan demikian, LKPD berbasis proyek pengolahan limbah kulit buah naga efektif dalam meningkatkan keterampilan berpikir kritis dan self-regulated learning peserta didik. Kata Kunci : LKPD Berbasis Proyek, Keterampilan Berpikir Kritis, SelfRegulated Learning This study aimed to determine the effectiveness of project-based LKPD using dragon fruit peel waste processing in improving students’ critical thinking skills and self-regulated learning on alternative energy material. The research was conducted at SMAN 1 Sumberejo using a quasi-experimental method with a pretest-posttest nonequivalent gr oup design. The sample consisted of classes X E1 and X E4 with a total of 66 students. The instruments used were essay tests on critical thinking skills and self-regulated learning questionnaires. The results showed that the average N-Gain of critical thinking skills was 0.65 in experimental class 1 and 0.67 in experimental class 2. The paired sample t-test showed a significance value of 0.001 < 0.05, indicating an improvement in students’ critical thinking skills. Meanwhile, the One Way ANOVA test showed no significant difference in improvement based on students’ initial abilities (0.165 > 0.05). The self-regulated learning questionnaire results obtained percentages of 89.93% and 92.81%, both categorized as very high. In addition, the bivariate correlation test showed a positive relationship between critical thinking skills and self-regulated learning with a Pearson correlation value of 0.50 in the moderate category. Therefore, project-based LKPD using dragon fruit peel waste processing was effective in improving students’ critical thinking skills and self-regulated learning.
