Penerapan E-LKPD Berbasis Model Guided Inquiry dalam Melatihkan Keterampilan Proses Sains Terintegrasi (KPST) Materi Fotosintesis Kelas XI SMA

Abstract

Keterampilan proses sains terintegrasi (KPST) merupakan kemampuan penting dalam pembelajaran biologi pada Kurikulum Merdeka, namun penguasaannya dijenjang SMA masih tergolong rendah. Tujuan studi ialah mengevaluasi efisiensi implementasi E-LKPD berlandaskan guided inquiry pada bahasan fotosintesis untuk mendongkrak keahlian proses sains yang terintegrasi bagi subjek didik. Melalui format one group pretest–posttest, penelitian ini menyertakan 22 peserta didik kelas XI MIPA yang kemudian diproses secara deskriptif kuantitatif memanfaatkan teknik persentase serta nilai normalized gain (n-gain). Temuan studi memaparkan progres capaian edukatif sekaligus kompetensi proses sains terintegrasi dengan skor rata-rata dari 43 saat awal menjadi 82 saat akhir serta indeks N-gain 0,7 pada level sedang. Pertumbuhan ini terekam bagi semua indikator KPST. Realisasi pengajaran maupun operasionalisasi E-LKPD berada pada taraf sangat baik melalui raihan persentase rata-rata 95%, disertai peningkatan aktivitas peserta didik dari 90% menjadi 96% 4selama proses pembelajaran. Reaksi subjek didik pun memaparkan evaluasi sangat positif dengan raihan 90%. Hasil tersebut menandakan bahwa media E-LKPD model guided inquiry bagi materi fotosintesis tergolong efektif maupun praktis dimanfaatkan untuk melatihkan kompetensi proses sains terintegrasi dalam ruang lingkup materi fotosintesis ini.

Integrated science process skills (KPST) are important abilities in biology learning in the Merdeka Curriculum; however, mastery at the senior high school level remains relatively low. The aim of the study is to evaluate the effectiveness of implementing E-LKPD based on guided inquiry on the topic of photosynthesis to enhance integrated science process skills among students. Using a one group pretest-posttest format, this study involved 22 students from class XI MIPA, which was then processed descriptively quantitatively using percentage techniques and normalized gain (n-gain) scores. The study findings demonstrate progress in educational achievement as well as integrated science process competencies, with an average score increase from 43 at the beginning to 82 at the end and an N-gain index of 0.7 at a moderate level. This growth was observed across all KPST indicators. The implementation of teaching and the operationalization of E-LKPD were rated as very good with an average percentage achievement of 95%, alongside an increase in student activity from 90% (meeting 1) to 96% (meeting 2) during the learning process. Student feedback also indicated a very positive evaluation with a score of 90%. These results indicate that the E-LKPD media using a guided inquiry model for the photosynthesis material is effective and practical for training integrated science process competencies within the scope of this photosynthesis material.
