Kualitas Sumber Daya Manusia (SDM) pada abad ke-21 perlu diperhatikan terutama dalam berbagai keahlian dan keterampilan yang dimiliki, seperti kemampuan kerja tim, kemampuan komunikasi, literasi, rasa keingintahuan yang besar, berpikir kritis, dan kreativitas. Oleh karena itu, penelitian ini bertujuan untuk memperoleh kelayakan LKPD berorientasi kimia hijau untuk melatihkan keterampilan berpikir kreatif pada materi larutan elektrolit dan non elektrolit. Terdapat tiga prinsip kimia hijau yang diterapkan pada pengembangan LKPD ini, prinsip nomor 1 yaitu mencegah terjadinya limbah, prinsip nomor 7 yaitu menggunakan bahan baku terbarukan, dan prinsip nomor 12 yaitu meminimalkan terjadinya kecelakaan kerja. Pengembangan LKPD ini menggunakan model pengembangan 4-D yang terdiri dari empat tahap yaitu, define (pendefinisian), design (perancangan), develop (pengembangan) dan disseminate (penyebaran). Namun, penelitian ini dibatasi sampai tahap develop (pengembangan). Kelayakan LKPD yang dikembangkan ditinjau dari kriteria kevalidan, kepraktisan, dan keefektifan. LKPD yang dikembangkan dinyatakan valid ditinjau dari skor validitas isi dan validitas konstruk. Hasil validasi pada kriteria validitas isi memperoleh skor modus 5 dengan kategori sangat baik, sedangkan validitas konstruk memperoleh skor modus 4 dengan kategori baik. LKPD yang dikembangkan dinyatakan praktis ditinjau dari hasil angket respon peserta didik dan didukung dengan hasil observasi aktivitas peserta didik serta hasil observasi keterlaksanaan pembelajaran selama uji coba terbatas yang masing-masing mendapatkan persentase sebesar 96.98%; 95.28%; dan 92.21% dengan kategori sangat praktis. LKPD yang dikembangkan dinyatakan efektif ditinjau dari peningkatan nilai pretest-posttest keterampilan berpikir kreatif peserta didik yang dianalisis dari perhitungan nilai N-gain dan memperoleh skor sebesar 0.74 dengan kategori tinggi. Berdasarkan hal tersebut dapat disimpulkan bahwa LKPD berorientasi kimia hijau untuk melatihkan keterampilan berpikir kreatif pada materi larutan elektrolit dan non elektrolit dinyatakan layak digunakan karena telah memenuhi kriteria kevalidan, kepraktisan, dan keefektifan.

The quality of Human Resources (HR) in the 21st century needs to be considered, especially in terms of various skills and expertise, such as teamwork ability, communication skills, literacy, great curiosity, critical thinking, and creative. Therefore, this research aims to obtain the feasibility of student worksheet orientation green chemistry to train creative thinking skills in electrolyte and non-electrolyte solution material. There are three principles of green chemistry that are applied in the development of this student worksheet, namely the 1st principle is waste prevention, the 7th principle is use of renewable feedstocks, and the 12th principle is inherently safer chemistry for accident prevention. The development of this student worksheet uses a 4-D development model which consists of four stages, namely define, design, develop and disseminate. However, this research is limited to the develop stage. The feasibility of the student worksheet being developed is reviewed from the criteria of validity, practicality and effectiveness. The student worksheet developed was stated valid in terms of content validity and construct validity scores. The validation results for the content validity criteria obtained a mode score of 5 in the very good category, while construct validity obtained a mode score of 4 in the good category. The student worksheet that was developed was stated to be practical in terms of the results of the student response questionnaire and supported by the results of observations of student activities and the results of observations of learning implementation during limited trials, each of which obtained a percentage of 96.98%; 95.28%; and 92.21% in the very practical category. The student worksheet developed was stated effective in terms of the increase in the pretest posttest score of students' creative thinking skills which was analyzed from the calculation of the N-gain value and obtained a score of 0.74 in the high category. Based on this, it can be concluded that student worksheet orientation green chemistry to train creative thinking skills in electrolyte and non-electrolyte solution material is stated feasible for use because it meets the criteria for validity, practicality and effectiveness.
