PENGEMBANGAN LEMBAR KEGIATAN PESERTA DIDIK (LKPD) BERBASIS LEARNING CYCLE 7E MATERI PENCEMARAN LINGKUNGAN UNTUK MELATIHKAN KETERAMPILAN PROSES SAINS

THE DEVELOPMENT OF STUDENT WOKRKSHEET BASED ON LEARNING CYCLE 7E ENVIRONMENTAL POLLUTION MATERIALS TO TRAIN SKILLS OF SCIENCE PROCESSES

Abstrak

Tujuan penelitian ini adalah (1). menghasilkan LKPD berbasis Learning Cycle 7E materi pencemaran lingkungan untuk melatihkan keterampilan proses sains yang valid, praktis dan efektif. (2). mendeskripsikan validitas LKPD. (3) mendeskripsikan kepraktisan LKPD. (4). mendeskripsikan keefektifan LKPD. LKPD yang dikembangkan  terdiri dari 2 LKPD. Topik LKPD 1 uji toksisitas larutan detergen terhadap ikan. Topik LKPD 2 fitoremediasi tanaman eceng gondok terhadap kualitas larutan detergen. LKPD dikembangkan dengan desain penelitian 4D yaitu define, design, develop dan disseminate tetapi tahap disseminate tidak dilakukan. Pengembangan LKPD dilakukan di Jurusan Biologi Universitas Negeri Surabaya. Kegiatan pembelajaran dilakukan sebanyak 3 kali pertemuan. Uji coba terbatas dilakukan pada 20 peserta didik kelas X MIPA 3 di SMA Negeri 1 Manyar Gresik. Parameter dalam penelitian ini adalah validitas LKPD ditinjau dari hasil validasi komponen isi, komponen penyajian, komponen kebahasaan, komponen kesesuaian dengan model Learning Cycle 7E dan komponen kesesuaian dengan keterampilan proses sains, kepraktisan LKPD ditinjau dari hasil observasi keterlaksanaan LKPD yang digunakan peserta didik selama kegiatan pembelajaran dan keefektifan LKPD ditinjau dari ketuntasan hasil belajar dan keterampilan proses sains. Analisis data dilakukan secara deskriptif kuantitatif. Berdasarkan hasil penelitian menunjukkan bahwa rata-rata hasil validasi LKPD sebesar 3,97 dengan kategori sangat valid. Kepraktisan LKPD sebesar 94,06% dengan kategori sangat praktis. Keefektifan LKPD ditinjau dari ketuntasan hasil belajar sebesar 90% dan keterampilan proses sains sebesar 95% dengan kategori sangat efektif.

Kata kunci: Learning Cycle 7E, Keterampilan proses sains, Pencemaran lingkungan.

Abstract

          The purpose of the study is to (1).  produce LKPD based on Learning Cycle 7E environmental pollution material to train valid, practical and effective science process skills. (2). describe the validity of LKPD. (3). describe the practicality of LKPD. (4). describe the effectiveness of LKPD. The developed LKPD consists of 2 LKPD. LKPD Topic 1 toxicity test for detergent solutions to fish. LKPD Topic 2 phytoremediation of water hyacinth plants on the quality of detergent solution. LKPD was developed with the 4D research design namely define, design, develop and disseminate but the disseminate stage was not carried out. LKPD development is carried out in the Department of Biology, State University of Surabaya. Learning activities carried out 3 times meeting. Limited trials were conducted on 20 students of Class X MIPA 3 in SMA Negeri 1 Manyar Gresik. The parameters in this study are the validity of LKPD in terms of the result of the validation of the content component, the presentation component, the linguistic component with the Learning Cycle 7E model and the conormance component with the science process sklis, the practicality of LKPD in terms of observations of LKPD implementation used by students during learning activities and the effectiveness of LKPD in terms of completeness of learning outcomes and science process skills. Data analysis was performed descriptively quantitative. Based on the results of the study showed that the average results of the LKPD validation was 3.97 with a very valid category. The practicality of LKPD is 94.06% with a very practical category. The effectiveness of LKPD in terms of completeness of learning outcomes was 90% and science process skills was 95% with a very effective category.

Keywords: Learning Cycle 7E, Science process skills, Environmental pollution.
