Pengembangan Lembar Aktivitas Peserta Didik Berbasis Project Based Learning untuk Meningatkan Kemampuan Literasi Sains Pada Materi Kimia Hijau

Pada era keterampilan abad 21 terjadi perkembangan ilmu pengetahuan dan teknologi seiring waktu. Kemampuan literasi sains dalam pembelajaran kimia abad 21 perlu untuk ditingkatkan. Berdasarkan hasil studi PISA 2022 skor literasi peserta didik Indonesia masih tergolong rendah yakni peringkat ke-67 dari 81 negara. Pembelajaran yang berpusat pasa guru dengan metode ceramah membuat peserta didik tidak terdorong memiliki kemampuan literasi sains. Penelitian ini bertujuan untuk menghasilkan lembar aktivitas peserta didik dengan model PjBL untuk meningkatkan literasi sains  pada materi kimia hijau. Metode penelitian yang digunakan adalah Research and Development dengan model 4D (define, design, develop, disseminate), namun terbatas sampai tahap pengembangan (develop). Kelayakan LAPD ditinjau dari aspek validitas, kepraktisan, dan keefektifan. Data hasil validasi diperoleh dari pengisian lembar validasi yang diisi oleh 2 dosen kimia UNESA dan 1 guru kimia SMA. LAPD dinyatakan valid berdasarkan perolehan modus sebesar 5 pada aspek validitas isi dan konstruk. Uji coba LAPD dilaksanakan di MA Unggul Sabira IIBS, Mojokerto dengan jumlah responden sebanyak 32 peserta didik kelas XI SMA. LAPD dinyatakan efektif berdasarkan hasil N-Gain tes kemampuan literasi sains memperoleh rata-rata skor N-Gain sebesar 0,83 dengan kategori tinggi. LAPD dinyatakan sangat praktis berdasarkan hasil keterlaksanaan pembelajaran selama tiga kali pertemuan memperoleh modus sebesar 5 dengan kategori terlaksana dengan sangat baik. Hasil observasi aktivitas peserta didik memperoleh rata-rata persentase aktivitas relevan sebesar 98,63%. Hasil respon peserta didik memperoleh rata-rata persentase sebesar 96,69% dengan kategori sangat baik. Berdasarkan hasil validitas, kepraktisan, dan keefektifan menunjukkan bahwa LAPD yang dikembangkan layak untuk digunakan peserta didik.

In the 21st century, there has beenadvancement in science and technology. Therefore, the ability toread and write science in 21st-century chemistry learning needs to be improved.Based on the results of the 2022 PISA study, the literacy scores of Indonesian students are stillrelatively low, ranking 67th out of 81 countries. This is due toteacher-centered learning with lecture methods that do not encourage studentsto develop scientific literacy skills. Therefore, this studyaims to produce student activity sheets using thePjBL model to improve science literacyin green chemistry material. Thus, the research method usedis Research and Development with the 4D model (define, design,develop, disseminate), but limited to the development stage (develop).The feasibility of the LAPD is reviewed from the aspects of validity, practicality, and effectiveness.The validation data was obtained from the validation sheet filled out by two UNESA chemistry lecturers and one high school chemistry teacher. The LAPD was declared valid based ona mode of 5 in terms of content and construct validity. The LAPD trialwas conducted at MA Unggul Sabira IIBS, Mojokerto, with a total of32 high school 11th grade students as respondents. The LAPD was declared effective based on the results of the N-Gain test of science literacy skills, which obtained an average N-Gain score of 0.83, categorized as high. The LAPD was declared very practical based on the results of the implementation of learning during three meetings, which obtained a mode of 5, categorized as very well implemented. The results of student activity observations obtained an average percentage of relevant activities of 98.63%. The results of student responses obtained an average percentage of 96.69% in the very good category. Based on the observation results of student activities, the average percentage of relevant activities was 98.63%. The results of student responses obtained an average percentage of 96.69% in the very good category. Based on the observation results of student activities, the average percentage of relevant activities was 98.63%. The results of student responses obtained an average percentage of 96.69% in the very good category. Based on the observation results of student activities, the average percentage of relevant activities was 98.63%. The results of student responses obtained an average percentage of 96.69% in the very good category. Based on the observation results of student activities, the average The results of the observation ofstudent activity obtained an average percentage of relevantactivity of 98.63%. The results of student responses obtained an average percentageof 96.69% in the excellent category. Based on the results of validity,practicality, and effectiveness, it was shown that the LAPD developed was suitablefor use by students.
