Penelitian ini bertujuan untuk mengetahui pengaruh penerapan e-LKPD berbasis STEMEC terhadap peningkatan kemampuan berpikir kritis dan pembentukan karakter siswa. Penelitian menggunakan pendekatan kuantitatif dengan desain quasi experiment yang melibatkan kelas eksperimen dan kelas kontrol. Pengumpulan data dilakukan melalui pre-test dan post-test serta lembar observasi. Hasil penelitian menunjukkan bahwa penerapan e-LKPD berbasis STEMEC efektif meningkatkan kemampuan berpikir kritis siswa, ditunjukkan oleh peningkatan nilai rata-rata dari 42 menjadi 87 serta perbedaan signifikan antara kelas eksperimen dan kontrol . Selain itu, pembelajaran ini juga mampu membentuk karakter positif siswa, seperti rasa ingin tahu, tanggung jawab, kerja keras, komunikatif, kreatif, dan peduli lingkungan. Dengan demikian, e-LKPD berbasis STEMEC efektif dalam meningkatkan kemampuan berpikir kritis dan karakter siswa.

This study aims to determine the effect of implementing STEMEC-based e-LKPD on improving students’ critical thinking skills and character development. The study employed a quantitative approach with a quasi-experimental design involving an experimental class and a control class. Data were collected through pre-tests, post-tests, and observation sheets. The results showed that the implementation of STEMEC-based e-LKPD was effective in improving students’ critical thinking skills, as indicated by the increase in the average score from 42 to 87 and a significant difference between the experimental and control classes. In addition, this learning approach also contributed to the development of positive student character, such as curiosity, responsibility, hard work, communicativeness, creativity, and environmental awareness. In conclusion, STEMEC-based e-LKPD is effective in improving students’ critical thinking skills and character. Keywords: e-LKPD, STEMEC, critical thinking, student character
