Pengembangan Lembar Kerja Peserta Didik Elektronik (E-LKPD) Pertumbuhan dan Perkembangan Tumbuhan Berbasis Guided Discovery untuk Melatihkan Keterampilan Proses Sains Terintegrasi

Keterampilan proses sains terintegrasi (KPST) merupakan salah satu tuntutan abad ke-21. Model guided discovery dapat diterapkan dalam pembelajaran untuk melatih keterampilan proses sains terintegrasi. Tujuan penelitian adalah menghasilkan E-LKPD Pertumbuhan dan Perkembangan Tumbuhan berbasis guided discovery untuk melatihkan keterampilan proses sains terintegrasi yang layak secara teoretis dan empiris. Penelitian ini merupakan penelitian pengembangan menggunakan mode 4D  yang terdiri dari define, design, develop, disseminate. Penelitian ini hanya sampai tahap develop. Kelayakan teoretis berdasarkan hasil validasi meliputi aspek penyajian, isi dan kebahasaan. Kelayakan empiris diperoleh dari nilai tes keterampilan proses sains terintegrasi dan respons peserta didik. E-LKPD dikategorikan layak secara teoretis jika mendapat skor ≥ 2,51. E-LKPD dikategorikan  layak secara empiris jika persentase peserta didik pada ketercapaian indikator keterampilan proses sains terintegrasi memperoleh  ≥ 76% dan respons peserta didik kriteria kuat ≥ 61%. Data dianalisis secara deskriptif kuantitatif. Hasil kelayakan teoretis pada uji validasi memperoleh skor 3,86 (sangat valid). Kelayakan empiris E-LKPD ditunjukkan hasil tes menunjukkan ketercapaian indikator  KPST memperoleh kriteria baik hingga sangat baik  yaitu merumuskan masalah, merumuskan hipotesis, mengidentifikasi variabel, melaksanakan percobaan, menyajikan data, menganalisis data, merumuskan kesimpulan berturut-turut sebesar 96,7%;91,7%; 86,6%;91%; 96%;78,3%; 91,7%, serta hasil respons peserta didik 97,25% (sangat kuat). E-LKPD dinyatakan layak secara teoretis dan empiris digunakan pada pembelajaran.

Integrated science process skills are one of the demands of the 21st century. The guided discovery model can be applied in learning to train integrated science process skills. The research aims to produce an E-LKPD based on guided discovery  for plant growth and development to train integrated science process skills that are theoretically and empirically feasible. This research is development research using the 4D mode, which consists of defining, designing, developing, and disseminating. This research only reached the development stage. Theoretical feasibility based on the validation results includes presentation, content, and language aspects. Empirical feasibility is obtained from the integrated science process skills test-score and students’ responses. E-LKPD is categorized as theoretically feasible if it scores ≥ 2.51. E-LKPD was classified as empirically feasible if the percentage of students on the achievement of integrated science process skills indicators ≥ 76% and strong criteria student responses ≥ 61%. The results of theoretical feasibility in the validation test obtained a score of 3.86 (very valid). The empirical feasibility of   E-LKPD is shown by the test results showing the achievement of integrated science process skills indicators obtaining good to very good criteria, namely formulating problems, formulating hypotheses, identifying variables, carrying out experiments, presenting data, analyzing data, formulating conclusions successively by 96.7%; 91.7%; 86.6%; 91%; 96%; 78.3%; 91.7%, and the results of students' responses 97.25% (very strong). E-LKPD is declared theoretically and empirically feasible to use in learning.

Key words: E-LKPD, guided discovery, growth and development of plants, integrated process skills.
