Abstract

Penelitian ini bertujuan untuk mengembangkan e-modul praktikum laju reaksi kimia berbasis green chemistry serta mengkaji pengaruhnya terhadap keterampilan berpikir kritis peserta didik ditinjau dari gaya belajar visual dan kinestetik. Pengembangan e-modul menggunakan model Research and Development (R&D) 4D, yang meliputi tahap define, design, develop, dan disseminate, dengan pengintegrasian prinsip green chemistry dalam konteks fenomena kehidupan seharihari. Validasi produk dilakukan oleh ahli materi, media, dan bahasa menggunakan indeks Aiken’s V,serta dilanjutkan dengan uji coba skala kecil dan skala besar. Hasil validasi menunjukkan nilai Aiken’s V sebesar 0,97 (materi), 0,98 (media), dan 0,97 (bahasa), yang melampaui batas minimal 0,80 dan menunjukkan kategori sangat layak. Uji kelayakan oleh guru dan peserta didik memperoleh persentase di atas 94%, sehingga e-modul dinyatakan sangat layak digunakan dalam pembelajaran. Menggunakan analisis data statistik untuk implementasinya adalah anava desain Faktorial 2x2. Uji prasyarat menunjukkan data berdistribusi normal (Asymp. Sig. = 0,069 > 0,05) dan homogen (Sig. Levene = 1,000 > 0,05), sehingga layak dianalisis menggunakan uji statistik parametrik. Hasil analisis efektivitas menunjukkan bahwa penggunaan e-modul praktikum berbasis green chemistry berpengaruh positif dan signifikan terhadap keterampilan berpikir kritis peserta didik (p < 0,05). Analisis signifikansi menunjukkan hubungan yang sangat kuat antara penggunaan bahan ajar dan keterampilan berpikir kritis, baik pada peserta didik visual maupun kinestetik. Secara parsial, e-modul memberikan pengaruh yang lebih besar dibandingkan modul teks praktikum, baik pada peserta didik visual (t = 16,914; p = 0,000) maupun kinestetik t = 14,516). Dengan demikian, e-modul praktikum laju reaksi kimia berbasis green chemistry terbukti efektif dan unggul dalam meningkatkan keterampilan berpikir kritis peserta didik dengan karakteristik gaya belajar yang berbeda. ********* This study aims to develop a green chemistry–based chemical reaction rate practicum e-module and to examine its effect on students’ critical thinking skills in terms of visual and kinesthetic learning styles. The e-module was developed using the 4D Research and Development (R&D) model, which consists of the define, design, develop, and disseminate stages, with the integration of green chemistry principles in the context of everyday life phenomena.Product validation was conducted by content, media, and language experts using Aiken’s V index, followed by small-scale and large- scale field trials. The validation results showed Aiken’s V values of 0.97 for content, 0.98 for media, and 0.97 for language, all exceeding the minimum threshold of 0.80, indicating that the e-module is highly valid. The feasibility assessment by teachers and students yielded percentages above 94%, confirming that the e-module is highly feasible for use in learning activities.For implementation, the data were analyzed using a 2 × 2 factorial ANOVA design. The prerequisite tests indicated that the data were normally distributed (Asymp. Sig. = 0.069 > 0.05) and homogeneous (Levene’s Sig. = 1.000 > 0.05), making them suitable for parametric statistical analysis. The effectiveness analysis revealed that the use of the green chemistry–based practicum e-module had a positive and significant effect on students’ critical thinking skills (p < 0.05). Regression analysis showed a very strong relationship between the use of instructional materials and critical thinking skills for both visual and kinesthetic learners). Partially, the e-module exerted a greater influence than the text module-based practicum module, both for visual learners ( t = 16.914; p = 0.000) and kinesthetic learners (t = 14.516; p = 0.000). Therefore, the green chemistry–based chemical reaction rate practicum e-module is proven to be effective and superior in enhancing students’ critical thinking skills across different learning style characteristics.
