PENGEMBANGAN E-LKPD BERBASIS GUIDED DISCOVERY DENGAN MEMANFAATKAN WEB OLABS UNTUK MENINGKATKAN KETERAMPILAN PROSES SAINS TERINTEGRASI MATERI FOTOSINTESIS

DEVELOPMENT OF A GUIDED DISCOVERY-BASED E-WORKSHEET UTILIZING THE OLABS WEBSITE TO ENHANCE INTEGRATED SCIENCE PROCESS SKILLS IN PHOTOSYNTHESIS MATERIAL

Keterampilan proses sains terintegrasi sangat diperlukan untuk meningkatkan kualitas pendidik di Indonesia. Penelitian ini bertujuan untuk mengembangkan E-LKPD berbasis Guided Discovery untuk meningkatkan keterampilan proses sains terintegrasi pada materi fotosintesis yang layak berdasarkan validitas, kepraktisan, dan keefektifan. Penelitian ini menggunakan ,model 4D (Define, Desaign, Develop dan Disseminate). Metode pengumpulan data melalui wawancara terbatas dan menggunakan instrument validasi, angket respon peserta didik, lembar observasi aktivitas peserta didik, dan lembar tes kemampuan keterampilan proses sains terintegrasi pretest-posttest. Subjek penlitian ini berjumlah 20 siswa kelas 12 IPA SMAN 20 Surabaya. Berdasarkan hasil analisis E-LKPD yang dikembangkan mendapat validitas rata-rata sebesar 96,8% dengan kategori sangat valid, sehingga dikatakan layak digunakan sebagai bahan ajar. Hasil kepraktisan E-LKPD mendapatkan kategori sangat praktis berdasarkan respon peserta didik yakni sebesar 97,6%. Keefektifan E-LKPD berdasarkan pretest-posttest memperoleh skor N-gain sebesar 0.79 dengan kategori peningkatan tinggi, sehingga E-LKPD efektif digunakan dalam kegiatan pembelajaran. Dapat disimpulkan bahwa E-LKPD berbasis Guided Discovery yang dikembangkan dinyatakan valid, praktis, dan efektif digunakan sebagai bahan ajar dalam pembelajaran serta mampu meningkatkan keterampilan proses sains terintegrasi peserta didik.

Integrated science process skills are essential for improving the quality of education in Indonesia. This study aims to develop a Guided Discovery-based electronic student worksheet (E-LKPD) to enhance integrated science process skills in photosynthesis material, evaluated in terms of validity, practicality, and effectiveness. The research employed the 4D model (Define, Design, Develop, and Disseminate). Data collection methods included limited interviews and the use of validation instruments, student response questionnaires, student activity observation sheets, and integrated science process skills tests (pretest and posttest). The research involved 20 twelfth-grade science students at SMAN 20 Surabaya. Based on the analysis, the developed E-LKPD obtained an average validity score categorized as "highly valid," with a validation percentage of 96.8%, indicating its feasibility as a teaching material. The practicality of the E-LKPD was rated as "highly practical" based on student responses, achieving a score of 97.6%. The effectiveness of the E-LKPD, based on the N-gain score from the pretest-posttest results, reached 0.79, which falls into the "high improvement" category. It can be concluded that the developed Guided Discovery-based E-LKPD is valid, practical, and effective for use as a teaching material and can enhance students' integrated science process skills.
