PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK BERORIENTASI KIMIA HIJAU UNTUK MELATIHKAN KETERAMPILAN BERPIKIR KREATIF PADA MATERI LAJU REAKSI

DEVELOPMENT OF STUDENT WORKSHEETS GREEN CHEMISTRY ORIENTED TO TRAIN CREATIVE THINKING SKILLS ON REACTION RATE TOPIC

Penelitian ini bertujuan untuk menghasilkan lembar kerja peserta didik berorientasi kimia hijau untuk melatihkan keterampilan berpikir kreatif pada materi laju reaksi yang layak. Prinsip-prinsip kimia hijau yang dikaji pada penelitian ini terbatas pada prinsip kimia hijau nomor 1, 5, dan 12. Metode penelitian pengembangan menggunakan model 4-D (define, design, develop, dan disseminate) dan dibatasi hanya sampai tahap develop. Uji coba terbatas dilakukan kepada 35 peserta didik di kelas XI IPA 1 Sekolah Menengah Atas. Pengembangan lembar kerja peserta didik dinyatakan layak apabila memenuhi tiga aspek, meliputi aspek validitas, kepraktisan, dan keefektifan. Dinyatakan valid apabila mendapatkan nilai modus minimal 3 dari rentang nilai 1-5, serta dinyatakan praktis dan efektif jika didapatkan hasil persentase ≥61%. Hasil pengembangan lembar kerja peserta didik disimpulkan bahwa kelayakan lembar kerja peserta didik pada aspek validitas teoritis terdiri dari beberapa hal, yaitu kriteria isi yang memperoleh nilai modus 5, kriteria kebahasaan memperoleh nilai modus 5, kriteria penyajian memeperoleh nilai modus 5, kriteria kegrafikaan memperoleh nilai modus 4, kriteria kimia hijau memperoleh nilai modus 5, dan kriteria keterampilan berpikir kreatif memperoleh nilai modus 5. Kepraktisan lembar kerja peserta didik ditinjau dari angket respon peserta didik yang didukung oleh observasi aktivitas peserta didik dan keterlaksanaan pembelajaran yang masing-masing memperoleh hasil praktis sekali dengan rata-rata persentase sebesar 94,64%, 94,5%, dan 98,21%. Aspek keefektifan ditinjau dari hasil tes kemampuan berpikir kreatif yang memperoleh 0,85 yang berada pada kategori tinggi. Berdasarkan hasil validitas, kepraktisan, dan keefektifan dapat disimpulkan bahwa lembar kerja peserta didik yang dikembangkan dinyatakan layak untuk digunakan dalam proses belajar mengajar.

This study aims to produce worksheets of green chemistry-oriented learners to practice creative thinking skills on feasible reaction rate material. The principles of green chemistry studied in this study are limited to green chemistry principles number 1, 5, and 12. The development research method uses a 4-D model (define, design, develop, and disseminate) and is limited only to the develop stage. The limited trial was conducted to 35 students in grade XI Science 1 Senior High School. The development of student worksheets is considered feasible if it meets three aspects, including aspects of validity, practicality, and effectiveness. Declared valid if you get a mode value of at least 3 from a range of values 1-5, and declared practical and effective if you get a percentage result of ≥61%. The results of the development of student worksheets concluded that the feasibility of student worksheets in the aspect of theoretical validity consists of several things, namely content criteria that obtain a mode value of 5, language criteria obtain a mode value of 5, presentation criteria obtain a mode value of 5, graphic criteria obtain a mode value of 4, green chemistry criteria obtain a mode value of 5, and creative thinking skills criteria obtain a mode value of 5. The practicality of student worksheets is seen from student response questionnaires supported by observations of student activities and learning implementation, each of which obtained practical results once with an average percentage of  94.64%, 94.5%, and 98.21%. The effectiveness aspect is reviewed from the results of the creative thinking ability test which obtained 0.85 which is in the high category. Based on the results of validity, practicality, and effectiveness, it can be concluded that the worksheets of students developed are declared suitable for use in the teaching and learning process.
