Abstract
Penelitian ini bertujuan untuk mengetahui pengaruh penerapan LKPD praktikum berbasis Project Based Learning (PjBL) terhadap keterampilan berpikir kritis peserta didik pada penjernihan air dengan koagulan alami. Metode penelitian yang digunakan adalah metode pra-eksperimen dengan desain penelitian one group pretest-posttest. Penelitian ini dilakukan di salah satu SMA Negeri di Kota Bandung dengan melibatkan partisipan sebanyak 35 peserta didik dan 5 orang validator yang terdiri dari 2 orang dosen dan 3 orang guru kimia. Instrumen penelitian yang digunakan yaitu lembar keterlaksanaan proyek, lembar observasi, LKPD praktikum berbasis PjBL dan rubrik penilaian LKPD, serta soal pretest-posttest. Hasil penelitian menunjukkan bahwa seluruh tahapan model pembelajaran PjBL pada proyek penjernihan air dengan koagulan alami mempunyai keterlaksanaan 100% (sangat baik). Indikator keterampilan berpikir kritis peserta didik yang muncul yaitu seluruh indikator yang meliputi indikator memberikan penjelasan sederhana, membangun keterampilan dasar, strategi dan taktik, klarifikasi lebih lanjut, serta menyimpulkan yang diperoleh dari data hasil pengolahan lembar observasi secara keseluruhan yang memperoleh skor dengan rentang 87%-93% dan berdasarkan data pengolahan tugas jawaban LKPD dengan rentang skor sebesar 83-100% yang termasuk ke dalam kategori sangat baik. Pengaruh penerapan LKPD praktikum berbasis PjBL terhadap keterampilan berpikir kritis peserta didik pada penjernihan air dengan koagulan alami memperoleh rata-rata N-gain sebesar 0,604 yang termasuk ke dalam kategori sedang. Hal ini menunjukkan bahwa penerapan LKPD praktikum berbasis PjBL pada penjernihan air dengan koagulan alami berpengaruh terhadap keterampilan berpikir kritis peserta didik. This research aims to determine the effect of the application of Project Based Learning (PjBL) based practicum worksheets on students' critical thinking skills on water purification with natural coagulants. The research method used was a pre-experiment method with a one group pretest-posttest research design. This research was conducted in one of the public high schools in Bandung City by involving participants as many as 35 students and 5 validators consisting of 2 lecturers and 3 chemistry teachers. The research instruments used were project implementation sheet, observation sheet, PjBL-based practicum worksheets and worksheet assessment rubric, and pretest-posttest questions. The research results show that all stages of the PjBL learning model in the water purification project with coagulants have 100% implementation (very good). The indicators of students' critical thinking abilities that emerged were all indicators which included indicators of elementary clarification, basic support, strategies and tactics, advanced clarification, inference obtained from the data resulting from processing the observation sheet as a whole, which obtained a score in the range of 87%- 93% and based on worksheets answer task processing data with a score range of 83%-100% which is included in the very good category. The effect of implementing PjBL-based practical LKPD on students' critical thinking skills in purifying water with natural coagulants obtained an average N-gain value of 0.604, which is in the medium category. This shows that the application of PjBL-based practicum worksheets on water purification with natural coagulants has an effect on students' critical thinking skills.
