LEMBAR KERJA PESERTA DIDIK (LKPD) BERWAWASAN GREEN CHEMISTRY UNTUK MENINGKATKAN KEMAMPUAN LITERASI SAINS PADA MATERI ASAM BASA

STUDENT WORKSHEET WITH GREEN CHEMISTRY INSIGHT TO INCREASE SCIENCETIFIC LITERACY ABILITY ON THE MATTER OF ACID BASE

Penelitian ini bertujuan untuk mendeskripsikan kelayakan Lembar Kerja Peserta Didik (LKPD) berwawasan green chemistry untuk meningkatkan kemampuan literasi sains pada materi asam basa. Prinsip green chemistry pada LKPD ini dibatasi pada 3 prinsip green chemistry nomor 1 yaitu mencegah terjadinya limbah, nomor 5 yaitu gunakan pelarut yang aman, dan nomor 12 yaitu meminimalkan terjadinya kecelakaan. Metode penelitian mengacu pada tahapan penelitian model pengembangan 4-P (pendefinisian, perancangan, pengembangan, dan penyebaran). Penelitian ini dibatasi sampai tahap pengembangan dan dilakukan uji coba terbatas kepada 12 peserta didik di salah satu SMA Negeri di Surabaya. Analisis data menggunakan metode deskriptif kuantitatif. Kelayakan ditinjau dari kevalidan, kepraktisan, dan keefektifan. LKPD dinyatakan valid, praktis, dan efektif jika diperoleh hasil persentase ≥61%. Hasil penelitian menunjukkan kelayakan LKPD ditinjau dari validitas isi sebesar 91,67% dan validitas konstruk sebesar 94,26% dengan kriteria sangat valid. Kepraktisan LKPD ditinjau dari aktivitas peserta didik sebesar 95% dengan interpretasi sangat baik dan respon peserta didik sebesar 95,09% dengan interpretasi sangat praktis. Keefektifan LKPD ditinjau dari nilai pretest dan posttest aspek literasi sains dengan skor N-gain sebesar 0,88 dalam kategori tinggi.

The study aims to describe the feasibility of student worksheet with green chemistry insight to increase scientific literacy ability on the matter of acid base. The principles of green chemistry in this student worksheets were limited 3 principles of green chemistry number 1 is preventing waste. number 5 is using safe solvent. and number 12 is minimizing the occurrencence of accidents.The research method was referred to the stage of 4-D development model (define, design, develop, and desseminate). This study is limited to the stage of development and limited test was conducted to 12 students of a state Senior High School. Analysis of the data uses quantitative descriptive methods. Feasibility in terms of validity, practicality, and effectiveness. Worksheet is stated to be valid, practical, and effective if the percentage results are obtained ≥61%. The result showed that the feasibility of student worksheets is reviewed from content validity a percentage of 91.67% and construct validity a percentage of 94.26% with very valid criteria. The practicality of student worksheets is reviewed from observation of student activities a percentage of 95% with very good interpretations and response of student a percentage of 95.09% with very practical interpretations. The effectiveness of the student worksheets reviewed from pretest and posttest of scientific literacy with N-gain score of 0.88 high category.
