Abstract

Penelitian ini bertujuan untuk mengembangkan LKPD praktikum berbasis inkuiri terbimbing
topik makromolekul pada pembuatan bioplastik dari pati singkong yang dapat digunakan
oleh peserta didik kelas XII tingkat SMA/MA. Desain penelitian yang digunakan adalah
educational design research dengan metode penelitian deskriptif kualitatif. Penelitian ini
melibatkan partisipan 12 orang peserta didik dan 5 orang validator dengan 2 orang dosen
kimia dan 3 orang guru kimia SMA. Instrumen penelitian yang digunakan berupa lembar
hasil optimasi, lembar hasil uji kelayakan LKPD, lembar observasi, lembar rubrik penilaian
LKPD dan lembar angket respon peserta didik. LKPD disusun berdasarkan hasil optimasi,
saran validator, dan indikator keterampilan inkuiri. Hasil optimasi pada pembuatan bioplastik
dari pati singkong diperoleh komposisi bubuk agar-agar 0,5 gram dan volume air 35 mL
untuk setiap 2 gram pati singkong dan 1 mL gliserin, sehingga menghasilkan bioplastik yang
kaku dan tidak mudah sobek. Hasil uji kelayakan LKPD praktikum yang dikembangkan pada
aspek kesesuaian komponen terhadap indikator keterampilan inkuiri dan kelayakan konsep
mendapat kategori sangat baik, kelayakan kesesuaian tata bahasa, tata letak serta perwajahan
termasuk dalam kategori baik sampai sangat baik. Keterlaksanaan praktikum berdasarkan
hasil observasi keterlaksanaan tahapan inkuiri dan hasil jawaban peserta didik pada LKPD
yang dikembangkan termasuk dalam kategori baik sampai sangat baik. Respon peserta didik
terhadap praktikum dan LKPD praktikum yang dikembangkan termasuk dalam kategori baik,
sehingga dapat disimpulkan bahwa LKPD praktikum yang dikembangkan layak digunakan
sebagai bahan ajar di SMA kelas XII.

This study aims to develop a guided inquiry-based practicum student worksheet (LKPD) on
the topic of macromolecules in the production of bioplastics from cassava starch, intended
for senior high school (SMA/MA) students in Grade XII. The research design used is
educational design research with a descriptive qualitative research method. This study
involved 12 student and 5 validators, consisting of 2 chemistry lecturers and 3 high school
chemistry teachers. The research instruments used include an optimization result sheet, a
feasibility test sheet for the LKPD, an observation sheet, an LKPD assessment rubric sheet,
and a student response questionnaire sheet. The LKPD was developed based on optimization
results, validator suggestions, and inquiry skill indicators. The optimization results in the
production of bioplastics from cassava starch showed a composition of 0.5 grams of agar
powder and 35 mL of water for every 2 grams of cassava starch and 1 mL of glycerin,
resulting in rigid and tear-resistant bioplastics. The feasibility test results of the developed
practicum LKPD on the aspect of component suitability to inquiry skill indicators and
concept feasibility were categorized as very good, and the feasibility of language, layout, and
presentation were categorized as good to very good. The implementation of the practicum,
based on the observation of the implementation of inquiry stages and the students' answers
on the developed LKPD, was categorized as good to very good. Student responses to the
practical activity and the developed practical LKPD were also rated from good. Therefore, it
can be concluded that the developed LKPD for practical work is suitable for use as teaching
material in Grade XII of senior high school.
Keywords: LKPD, guided inquiry, practical work, bioplastic, starch
