PENGEMBANGAN E-LKPD INTERAKTIF PENCEMARAN LINGKUNGAN BERBASIS INKUIRI TERBIMBING UNTUK MELATIHKAN KETERAMPILAN PROSES SAINS KELAS X SMA

DEVELOPMENT OF INTERACTIVE E-WORKSHEET ON ENVIRONMENTAL POLLUTION BASED ON GUIDED INQUIRY TO TRAIN SCIENCE PROCESS SKILLS OF GRADE 10 STUDENTS

        Keterampilan proses sains merupakan elemen penting dalam membentuk karakter ilmiah peserta didik. Namun, rendahnya pencapaian keterampilan ini di Indonesia menuntut inovasi pembelajaran yang mendukung proses ilmiah secara aktif. Materi pencemaran lingkungan relevan karena bersifat aplikatif dan dekat dengan kehidupan sehari-hari. Penelitian ini bertujuan menghasilkan E-LKPD interaktif berbasis inkuiri terbimbing pada materi pencemaran lingkungan untuk melatihkan keterampilan proses sains yang layak ditinjau dari validitas, kepraktisan, dan keefektifan. E-LKPD interaktif yang dikembangkan menghadirkan sejumlah keunggulan inovatif, yaitu: merekam waktu pengerjaan secara otomatis, terintegrasi dalam satu situs website tanpa perlu berpindah ke laman lain, dilengkapi dengan umpan balik otomatis pada tiap soal dan umpan balik keseluruhan, dapat diunduh dan dikerjakan secara offline. Model pengembangan yang digunakan adalah 4D yang diujicobakan secara terbatas pada 20 peserta didik kelas X-1 SMA Ta’miriyah Surabaya. Validitas E-LKPD ditelaah oleh tiga validator yaitu dosen ahli materi, ahli pendidikan, dan guru Biologi SMA, kepraktisan ditinjau dari keterlaksanaan aktivitas pembelajaran dan respon peserta didik, serta keefektifan ditinjau dari hasil belajar dan ketercapaian indikator keterampilan proses sains. Teknik analisis data yang digunakan yaitu deskriptif kuantitatif. Hasil penelitian menunjukkan E-LKPD interaktif ini skor validitasnya mencapai 98,89% (sangat valid). Kepraktisan ditinjau dari keterlaksanaan aktivitas pembelajaran sebesar 98% (sangat praktis) dan respons peserta didik sebesar 97,64% (sangat positif). Keefektifan menghasilkan ketuntasan tes keterampilan proses sains 100% dan ketercapaian indikator keterampilan proses sains mencapai skor N-gain sebesar 0,84. Dengan demikian, E-LKPD interaktif berbasis inkuiri terbimbing dinyatakan layak: valid, praktis, efektif, meningkatkan keterampilan proses sains kelas X SMA pada materi pencemaran lingkungan. 

Kata Kunci: E-LKPD interaktif, keterampilan proses sains, materi pencemaran lingkungan.

Science process skills are essential elements in shaping students’ scientific character. However, the low achievement of these skills in Indonesia highlights the urgent need for innovative learning approaches that actively support scientific inquiry. Environmental pollution is considered a relevant topic due to its applicative nature and close relation to daily life. This study aims to develop a guided inquiry-based interactive electronic student worksheet (E-LKPD) on environmental pollution that is feasible in terms of validity, practicality, and effectiveness for training science process skills. The developed interactive E-LKPD offers several innovative features, including automatic tracking of completion time, full integration within a single website without the need to switch between pages, automated feedback for each question and overall performance, and the ability to be downloaded and used offline. The development followed the 4D model and was tested on a limited scale with 20 tenth-grade students in Class X-1 at SMA Ta’miriyah Surabaya. The E-LKPD was validated by three experts: a subject matter expert, an education expert, and a senior high school biology teacher. Practicality was assessed through the implementation of learning activities and student responses, while effectiveness was evaluated based on learning outcomes and the achievement of science process skill indicators. The data were analyzed using descriptive quantitative methods. The results showed that the E-LKPD achieved a validity score of 98.89% (very valid). Practicality was rated at 98% based on implementation (very practical), and student responses reached 97.64% (very positive). In terms of effectiveness, 100% of students achieved mastery in the science process skills test, with an N-gain score of 0.84. Therefore, the guided inquiry-based interactive E-LKPD is considered feasible, valid, practical, and effective, for improving science process skills among tenth-grade students in the topic of environmental pollution.
