PENGEMBANGAN ELEKTRONIK LEMBAR KERJA PESERTA DIDIK (E-LKPD) BERBASIS PROBLEM BASED LEARNING PADA MATERI PERUBAHAN LINGKUNGAN UNTUK MELATIHKAN KEMAMPUAN BERPIKIR KRITIS SISWA KELAS X : Mendukung SDG’s Poin 6 dan 12

THE DEVELOPMENT OF ELECTRONIC STUDENT WORKSHEETS (E-LKPD) BASED ON PROBLEM BASED LEARNING ON ENVIRONMENTAL CHANGE TO TRAIN CRITICAL THINKING SKILLS OF GRADE X STUDENTS: Supporting SDG’s Points 6 and 12

Penelitian pengembangan ini bertujuan untuk menghasilkan E-LKPD berbasis PBL pada materi perubahan lingkungan untuk melatihkan kemampuan berpikir kritis yang layak meliputi valid, praktis, dan efektif. Jenis penelitian merupakan penelitian pengembangan yang menggunakan model 4-D yang terdiri atas Define, Design, Development, dan Dessiminate. Penelitian ini menghasilkan dua E-LKPD yang berisi kegiatan pembelajaran dan memuat fitur-fitur sesuai dengan model pembelajaran PBL. Parameter yang digunakan dalam penelitian ini berupa validitas E-LKPD meliputi aspek kelayakan penyajian, aspek kelayakan isi, dan aspek kelayakan bahasa, kepraktisan E-LKPD berdasarkan keterlaksanaan aktivitas peserta didik dan respon peserta didik selama menggunakan E-LKPD, serta efektivitas ditinjau dari hasil belajar peserta didik pada hasil pretest-posttest dan ketercapaian indikator berpikir kritis. Validitas E-LKPD memperoleh nilai sebesar 96,3% terkategori sangat valid. Kepraktisan ditinjau dari keterlaksanaan pembelajaran sebesar 96% untuk E-LKPD pencemaran air, 95% untuk E-LKPD pencemaran tanah yang terkategori sangat praktis serta respon peserta didik terhadap E-LKPD berbasis PBL menunjukkan persentase 96% terkategori sangat praktis. Keefektifan ditinjau berdasarkan hasil belajar peserta didik dengan rata-rata 81% terkategori baik (efektif) dan ketercapaian indikator berpikir kritis peserta didik menunjukkan adanya peningkatan terhadap kemampuan berpikir kritis dengan N-gain 0,54 kategori sedang. Berdasarkan hasil data yang diperoleh menunjukkan bahwa E-LKPD dapat dikatakan telah memenuhi syarat kelayakan suatu bahan ajar dalam mendorong minat belajar peserta didik yang valid, praktis, dan efektif serta mendukung SDG’s poin 6 dan 12.

This development research aims to produce a Problem Based Learning (PBL) based electronic student worksheet (E-LKPD) on environmental change materials designed to cultivate students’ critical thinking skills. The quality of the developed E-LKPD was evaluated based on its validity, practicality, and effectiveness. The study employed the 4-D development model, which consists of the stages: Define, Design, Develop, and Disseminate. The final product consists of two E-LKPDs, each incorporating structured learning activities and features aligned with the PBL approach. The research parameters comprised the validity of the E-LKPD measured through presentation, content, and language appropriateness; its practicality assessed through the implementation rate of student activities and learner responses during use; and its effectiveness analyzed through pretest-posttest learning outcomes and the achievement of critical thinking indicators. The validity score reached 96.3%, classified as highly valid. The practicality, measured from the learning implementation, scored 96% for the water pollution E-LKPD and 95% for the soil pollution E-LKPD, both categorized as highly practical. In addition, 96% of students responded positively to the PBL-based E-LKPDs, reinforcing their practical value. As for effectiveness, the average student learning outcomes reached 81%, indicating a high (effective) category, while the critical thinking gain score (N-gain) averaged at 0.54, classified as moderate. The findings demonstrate that the developed E-LKPDs meet the essential criteria of an effective instructional resource being valid, practical, and effective while simultaneously fostering student engagement and supporting the attainment of Sustainable Development Goals (SDGs), particularly goals 6 and 12.
