    Abstract

    Penelitian ini bertujuan untuk menghasilkan LKPD praktikum berbasis Project Based Learning (PjBL) topik makromolekul pada pembuatan edible coating dari pati talas yang dapat digunakan oleh peserta didik kelas XII tingkat SMA/MA. Desain penelitian yang digunakan adalah educational design research yang dilakukan dua tahap yaitu tahap pendahuluan dan tahap pengembangan. Penelitian ini dilakukan di salah satu SMA di kabupaten Bandung dengan melibatkan partisipan 12 orang peserta didik dan 5 orang validator dengan 2 orang dosen Pendidikan Kimia dan 3 orang guru kimia SMA. Instrumen penelitian yang digunakan berupa, lembar angket analisis kebutuhan LKPD, lembar hasil optimasi, lembar uji kelayakan LKPD, lembar observasi, lembar rubrik penilaian LKPD dan lembar angket respon peserta didik. LKPD disusun berdasarkan prosedur praktikum hasil optimasi, sintaks PjBL, saran validator, dan unsur penyusun LKPD. Hasil optimasi diperoleh komposisi optimum untuk pembuatan edible coating yaitu gliserol 4% 1 mL, kitosan 3% 25 mL, dan pati talas 3%, sehingga buah yang dilapisi edible coating dari pati talas terjaga kekerasannya, tidak mudah mengkerut, dan memiliki susut bobot yang rendah. Hasil uji kelayakan LKPD praktikum yang dikembangkan pada aspek kesesuaian komponen LKPD dengan sintaks PjBL, kelayakan tata bahasa, kelayakan unsur penyusun LKPD, kelayakan tata letak dan perwajahan termasuk dalam kategori sangat baik. Keterlaksanaan praktikum berdasarkan hasil observasi keterlaksanaan sintaks PjBL dan hasil jawaban peserta didik terhadap LKPD yang dikembangkan termasuk dalam kategori sangat baik. Respon peserta didik terhadap praktikum dan LKPD praktikum yang dikembangkan termasuk dalam kategori baik. Sehingga LKPD praktikum yang dikembangkan layak digunakan sebagai bahan ajar di SMA kelas XII.

    This study aims to produce a practicum worksheet based on Project Based Learning (PjBL) on the topic of macromolecules in the manufacture of edible coating from taro starch that can be used by grade XII students of SMA/MA. The research design used is educational design research which is carried out in two stages, namely the preliminary stage and the development stage. This research was conducted in one of the SMA in Bandung district involving 12 students and 5 validators with 2 Chemistry Education lecturers and 3 SMA chemistry teachers. The research instruments used were in the form of a LKPD needs analysis questionnaire sheet, optimization result sheet, LKPD feasibility test sheet, observation sheet, LKPD assessment rubric sheet and student response questionnaire sheet. LKPD is compiled based on the optimization result practicum procedure, PjBL syntax, validator suggestions, and LKPD constituent elements. The optimization results obtained the optimum composition for making edible coating, namely glycerol 4% 1 mL, chitosan 3% 25 mL, and taro starch 3%, so that the fruit coated with edible coating from taro starch maintains its hardness, does not easily shrink, and has low weight loss. The results of the feasibility test of the developed LKPD practicum on the aspects of the suitability of the LKPD components with the PjBL syntax, the feasibility of grammar, the feasibility of the elements of the LKPD, the feasibility of the layout and appearance are included in the very good category. The implementation of the practicum based on the results of observations of the implementation of the PjBL syntax and the results of students' answers to the developed LKPD are included in the very good category. Students' responses to the practicum and the developed LKPD practicum are included in the good category. So that the developed LKPD practicum is suitable for use as teaching materials in high school class XII.
