| Summary: | Penelitian ini bertujuan untuk menghasilkan E-LKPD topik reaksi transesterifikasi pada pembuatan biodiesel berbasis green chemistry sebagai bahan ajar untuk meningkatkan literasi sains peserta didik. Desain penelitian diadaptasi dari model pengembangan educational design research dari Plomp (2013), dengan tahapan sebagai berikut: (1) tahap pendahuluan, (2) tahap pengembangan, dan (3) tahap penilaian. Instrumen penelitian yang digunakan berupa lembar pemetaan perumusan tujuan pembelajaran yang sesuai dengan aspek PISA 2018 dan kurikulum 2013, lembar optimasi percobaan, lembar validasi E-LKPD, lembar observasi uji pengembangan, lembar pedoman penilaian jawaban peserta didik dan lembar angket respon peserta didik. Hasil penelitian berupa rumusan tujuan pembelajaran yang mencakup konteks pembuatan biodiesel dan konten kimia mengenai struktur, tata nama, sifat, penggolongan, kegunaan, dan dampak suatu produk dari lemak pada aspek sikap, pengetahuan, dan keterampilan yang disusun berdasarkan KI, KD Kurikulum 2013 serta aspek Kompetensi PISA 2018. Hasil optimasi percobaan pembuatan biodiesel yang cocok digunakan di laboratorium SMA adalah 12 mL minyak dimasukkan ke dalam labu Erlenmeyer, 0,12 g KOH dilarutkan dengan 4,5 mL CH3OH lalu dimasukkan ke dalam labu Erlenmeyer berisi minyak, Labu Erlenmeyer ditutup dengan sumbat karet yang dilengkapi tabung reaksi berisi air. Labu Erlenmeyer tersebut dipanaskan dalam penangas air bersuhu 650C selama 10 menit sambil digoyangkan., kemudian hasil reaksi ditampung dalam botol vial, lalu diamati. Hasil uji pengembangan berdasarkan keterlaksanaan tahapan inkuiri termasuk kategori sangat baik, sedangkan berdasarkan secara keseluruhan jawaban peserta didik terhadap tugas-tugas yang diberikan sudah memenuhi kriteria ketuntasan belajar. Respon peserta didik terhadap pelaksanaan praktikum dengan E-LKPD yang dikembangkan termasuk ke dalam kategori sangat baik. This study aims to produce electronic worksheets on the topic of transesterification reactions in production of biodiesel based on green chemistry as teaching materials to increase student scientific literacy. The research design was adapted from the educational design research development model from Plomp (2013), with the following stages: (1) preliminary stage, (2) development stage, and (3) assessment stage. The research instruments used mapping sheets for the formulation of learning objectives that were in accordance with aspects of the 2018 PISA and 2013 curriculum, trial optimization sheets, electronic worksheets validation sheets, development test observation sheets, guide sheets for assessing student answers and student response questionnaire sheets. The results of the research are formulation of learning objectives which include the context of making biodiesel and chemical content regarding structure, nomenclature, properties, classification, function, and impact of product from fat on aspects of attitudes, knowledge, and skills which are arranged based on KI, KD Curriculum 2013 and aspects Competency of PISA 2018. The results of an optimization experiment for making biodiesel suitable for use in Senior High School laboratories are 12 mL of oil put into Erlenmeyer flask, 0.12 g of KOH dissolved with 4.5 mL of CH3OH and then put into Erlenmeyer flask filled with oil, the Erlenmeyer flask is closed with rubber stopper equipped with a test tube filled with water. Erlenmeyer flask was heated in water bath at 650C for 10 minutes while being shaken, then the reaction results were collected in vial, then observed. The results of development test based on the implementation of inquiry stages are in the very good category, while based on the overall student answers to assignments given they have met the learning completeness criteria. The student response to implementation of the practicum with the developed electronic worksheets was included in very good category. |
