Abstrak

            Pada masa Pembelajaran Jarak Jauh (PJJ) secara online diperlukan bahan ajar elektronik yang dapat memfasilitasi dalam pembelajaran biologi sekaligus melatihkan keterampilan proses sains terintegrasi untuk memaksimalkan pembelajaran online. Salah satu metode yang menuntun dalam proses penemuan untuk memfasilitasi ketrampilan proses sains terintegrasi yaitu Guided Discovery (GD). Tujuan penelitian ini adalah mengembangan bahan ajar untuk menghasilkan e-LKPD berbasis guided discovery untuk melatih keterampilan proses sains terintegrasi pada materi fotosintesis yang layak berdasarkan validitas, kepraktisan, dan keefektifan. Penelitian ini mengunakan pengembangan model 4-D yakni Define, Design, Develop, tanpa Disseminate. Data penelitian yang didapatkan dari pengembangan e-LKPD ini berasal dari hasil telaah, validasi oleh para ahli, data hasil observasi keterlaksanaan oleh observer, dan data hasil pretest dan posttest serta data respon peserta didik. Kriteria penilaian untuk validitas dinyatakan valid apabila persentasenya ≥ 61%, sedangkan penilaian kepraktisan dinyatakan praktis apabila persentase observasi keterlaksanaan mencapai ≥ 51% dan dikategorikan efektif berdasarkan ketuntasan indikator keterampilan proses sains terintegrasi apabila peserta didik mendapat skor tes ≥ 75. Data yang diperoleh kemudian dianalisis secara deskriptif kuantitatif. Hasil analisis menunjukkan bahwa e-LKPD yang dikembangkan mendapat persentase validitas sebesar 98,05% dengan kategori sangat valid. Hasil kepraktisan mendapatkan persentase sebesar 84,77% dengan kategori sangat praktis. Hasil keefektifan mendapatkan beberapa hasil diantaranya ketuntasan tes keterampilan proses sains terintegrasi sebesar 92%, ketercapaian indikator keterampilan proses sains terintegrasi sebesar 89,3%, dan respon positif peserta didik terhadap e-LKPD yang dikembangkan sebesar 96,8%. Dengan begitu, e-LKPD yang dihasilkan berdasarkan aspek validitas, kepraktisan dan keefektifan dinyatakan layak untuk digunakan dalam pembelajaran.

Abstract

In the online distance learning period, electronic teaching materials that can facilitate learning biology as well as train integrated science process skills are needed to maximize online learning. One method that guides the discovery process to facilitate integrated science process skills is Guided Discovery. This study was conduct to produce e-LKPD based on guided discovery to train integrated science process skills on photosynthetic material that are feasible based on validity, practicality, and effectiveness. This research used the 4-D development model namely Define, Design, Develop, without Disseminate. The data were obtained from the result of reviews, validation by experts, observation of compliance by observers, pretest and posttest results and also student responses. The assessment criteria for validity were declared valid if the percentage is ≥ 61%, while the practicality assessment is declared practical if the percentage of observations of compliance reach ≥ 51% and is categorized as effective based on the completeness of the indicators of integrated science process skills if the student gets a test score of ≥ 75. The data were analyzed using descriptive quantitative tehnique. The results showed that the developed e-LKPD has a validity percentage of 98.05% with a very valid category. The practicality results get a percentage of 84.77% with a very practical category. The results of the effectiveness of obtaining several results include the completeness of the integrated science process skills test of 92%, the achievement of the integrated science process skills indicator of 89.3%, and the positive response of students to the developed e-LKPD of 96.8%. That way, the e-LKPD produced based on the aspects of validity, practicality and effectiveness is declared suitable for use in learning.
