PENGEMBANGAN LKPD PRAKTIKUM BERBASIS PROJECT BASED LEARNING PADA PEMBUATAN EDIBLE STRAW DARI PATI KACANG HIJAU TOPIK POLIMER
Penelitian ini bertujuan untuk mengembangkan LKPD praktikum berbasis project based learning melalui pembuatan edible straw dari pati kacang hijau pada topik polimer yang layak. Metode penelitian yang digunakan adalah Educational Design Research model Plomp & Nieveen, yang mencakup tahap pendahuluan, pengembangan, dan evaluasi. Partisipan dalam penelitian ini terdiri atas dua dosen Program Studi Pendidikan Kimia UPI dan tiga guru kimia SMA sebagai validator, empat orang observer, serta 12 peserta didik kelas XII dari salah satu SMA di Kabupaten Bandung yang terlibat dalam uji coba terbatas. Instrumen yang digunakan meliputi angket analisis kebutuhan, prosedur optimasi, lembar uji kelayakan LKPD, rubrik penilaian LKPD, lembar observasi, dan lembar angket respons peserta didik. Berdasarkan hasil optimasi, komposisi edible straw paling optimal yaitu 3 gram pati, 20 mL air, 2 gram gelatin, 1 mL gliserin dan 3 tetes essence makanan. Uji kelayakan pada aspek kesesuaian instruksi dengan tahapan PJBL, unsur penyusun LKPD, tata bahasa, serta tata letak dan perwajahan ada pada kategori sangat baik. Keterlaksanaan praktikum berdasarkan hasil observasi dan jawaban peserta didik terhadap LKPD yang dikembangkan termasuk dalam kategori sangat baik. Respons peserta didik terhadap praktikum menggunakan LKPD yang dikembangkan menunjukkan kategori sangat baik. Dengan demikian, LKPD praktikum berbasis PjBL ini dinyatakan layak digunakan sebagai bahan ajar pada pembelajaran kimia di jenjang SMA/MA/SMK. This study aims to develop a Project Based Learning based practicum worksheet (LKPD) through the production of edible straws from mung bean starch on the topic of polymers that is feasible for use in learning. The research method employed was Educational Design Research (EDR) by Plomp & Nieveen, which includes the preliminary, development, and evaluation phases. The participants in this study included two lecturers from the Chemistry Education Study Program at UPI and three high school chemistry teachers as validators, four observers, and 12 twelveth-grade students from a senior high school in Bandung Regency who were involved in the limited trial. The instruments used included a needs analysis questionnaire, optimization procedure, feasibility test sheets, observation sheets, assessment rubrics, and student response questionnaires. The results showed that teachers considered polymers important but abstract, indicating the need for practicum worksheets. The optimization results revealed the most optimal edible straw composition was 3 grams of starch, 20 mL of water, 2 grams of gelatin, 1 mL of glycerin, and 3 drops of food essence. The feasibility test on aspects of instruction alignment with PjBL stages, LKPD components, language, and layout were all in the very good category. The implementation of the practicum, based on observation and students’ responses in the worksheet, was effective and also categorized as very good. Furthermore, student responses indicated a very positive category. Thus, the PjBL-based practicum worksheet is declared feasible to be used as a learning material in chemistry education at the senior high school level SMA/MA/SMK.
