PENGEMBANGAN E-LKPD BERBASIS PROBLEM BASED LEARNING MATERI SISTEM PENCERNAAN UNTUK MELATIHKAN LITERASI SAINS SISWA KELAS XI SMA GUNA MENDUKUNG TERWUJUDNYA SDGs 3

DEVELOPMENT OF E-LKPD BASED PROBLEM BASED LEARNING ON THE DIGESTIVE SYSTEM TO TRAIN SCIENCE LITERACY OF GRADE XI HIGH SCHOOL STUDENTS TO SUPPORT THE REALIZATION OF SDGs 3

Literasi sains menjadi salah satu kemampuan yang perlu dikembangkan dalam pembelajaran biologi agar peserta didik mampu memahami dan menerapkan konsep ilmiah. Namun, capaian literasi sains peserta didik Indonesia masih tergolong rendah sehingga diperlukan pembelajaran yang lebih kontekstual. Salah satu materi yang berpotensi melatihkan literasi sains adalah sistem pencernaan karena menyajikan berbagai permasalahan autentik kehidupan sehari-hari. Oleh karena itu, diperlukan bahan ajar yang mampu memfasilitasi peserta didik dalam menyelesaikan permasalahan tersebut. Penelitian ini bertujuan mengembangkan E-LKPD berbasis Problem Based Learning (PBL) pada materi sistem pencernaan untuk melatihkan literasi sains peserta didik sekaligus mendukung pencapaian Sustainable Development Goals (SDGs) poin 3 “Kesehatan dan Kesejahteraan”. Metode pada penelitian ini menggunakan model 4D (Define, Design, Develop, dan Disseminate). Uji coba dilakukan pada 36 peserta didik kelas XI SMA Sunan Giri Menganti. Data penelitian dikumpulkan melalui lembar validasi, observasi, angket, serta Pre-Test dan Post-Test. Hasil penelitian menunjukkan bahwa E-LKPD yang dikembangkan memenuhi kriteria sangat valid dengan persentase validitas sebesar 96,7%, sangat praktis berdasarkan keterlaksanaan pembelajaran sebesar 98,3% dan respons peserta didik sebesar 98,6%, serta efektif dalam melatihkan literasi sains yang ditunjukkan oleh rata-rata nilai N-Gain sebesar 0,75 dengan kategori tinggi. Dari hasil yang didapatkan tersebut, E-LKPD yang dikembangkan mampu melatihkan literasi sains karena peserta didik dapat memahami dan menyelesaikan permasalahan kesehatan berdasarkan bukti ilmiah mengenai pola makan sehat, pemenuhan gizi seimbang, dan pencegahan gangguan pencernaan sehingga mendukung pencapaian SDGs poin 3.

Scientific literacy is a crucial skill to develop in biology education, enabling students to understand and apply scientific concepts. However, scientific literacy levels among Indonesian students remain low, necessitating a more contextual approach to learning. The digestive system is a particularly suitable topic for fostering scientific literacy, as it presents various authentic, real-life issues. Consequently, there is a need for instructional materials that facilitate students in addressing these issues. This study aimed to develop an electronic student worksheet (E-LKPD) based on the Problem-Based Learning (PBL) model, focusing on the digestive system, to cultivate students' scientific literacy while supporting the achievement of Sustainable Development Goal (SDG) 3: "Good Health and Well-being." The study employed the 4D development model (Define, Design, Develop, and Disseminate). Trials were conducted with 36 Grade XI students at SMA Sunan Giri Menganti. Data were collected through validation sheets, observations, questionnaires, and pre- and post-tests. The results demonstrated that the developed E-LKPD met the criteria for being highly valid (96.7% validity score), highly practical (98.3% learning implementation rate and 98.6% student response rate), and effective in fostering scientific literacy (indicated by an average N-Gain score of 0.75, falling into the high category). These findings suggest that the developed E-LKPD successfully fosters scientific literacy by enabling students to understand and resolve health-related issues such as healthy eating habits, balanced nutrition, and the prevention of digestive disorders based on scientific evidence, thereby supporting the achievement of SDG 3.
