Pengembangan Lembar Kegiatan Peserta Didik Berbasis Problem Based Learning pada Materi Bakteri untuk Melatihkan Keterampilan Literasi Sains Peserta Didik Kelas X

The Development of Student Worksheet Based on Problem Based Learning on Bacteria Topic to Train Science Literacy Skill of Students in Class X

Penelitian ini bertujuan untuk menghasilkan LKPD berbasis Problem Based Learning pada materi bakteri untuk melatihkan keterampilan literasi sains peserta didik kelas X SMA yang valid, praktis dan efektif. Penelitian ini menggunakan model 4-D yang terdiri dari tahap define, design, develop dan disseminate, namun pada tahap disseminate tidak dilakukan. Penelitian menggunakan uji coba terbatas pada 35 peserta didik kelas X di SMAN 14 Surabaya. Data dianalisis dari hasil validasi, keterlaksanaan LKPD dalam kegiatan pembelajaran, hasil pengerjaan LKPD, hasil belajar dan respon peserta didik secara statistik deskriptif kualitatif dan kuantitatif. Hasil validasi menunjukkan LKPD dinilai sangat valid dengan skor validasi sebesar 3,65. Kepraktisan LKPD diukur berdasarkan keterlaksanaan LKPD dalam pembelajaran dan hasil pengerjaan LKPD oleh peserta didik. Keterlaksanaan LKPD memperoleh persentase sebesar 100%. Hasil pengerjaan LKPD 1 dan 2 memperoleh nilai 72,0 dan 92,8. Ketuntasan indikator literasi sains dari pengerjaan LKPD 1 dan 2 memperoleh persentase sebesar 83,7% dan 100%. Keefektifan LKPD diukur berdasarkan hasil belajar dan respon peserta didik. Hasil belajar peserta didik ditinjau dari rata-rata nilai pre-test sebesar 40,5 dan rata-rata nilai post-test sebesar 90,2. Respon peserta didik mendapatkan skor rata-rata 93,3% dengan kategori sangat baik. Dengan demikian LKPD berbasis PBL dinyatakan sangat valid, praktis dan efektif untuk digunakan dalam pembelajaran materi bakteri.

The research aimed to produce a Problem Based Learning student worksheet on bacteria topic to practice student science literate skills of 10th grade senior high school which valid, practical and effective. This research used 4-D model consist of define, design, develop and disseminate, but at stage of disseminate is not done. This research had been held in limited implementation for 35 students in SMAN 14 Surabaya. Data obtained from validation, observation, student test and questionnaire were analyzed qualitatively and quantitatively using descriptive statistics. The validation result showed that the student worksheet were properly with the value of 3.65. The practicality of worksheet is measured based on the observation of worksheet and the result of worksheet work. The observation of worksheet get a percentage of 100%. The result of worksheet work 1 and 2 scored 72.0 and 92.8. The completeness of science literacy indicators from worksheet work 1 and 2 get a percentage of 83.7% and 100%. Student achievement was effective based on students achievement and responses. Students achievement average score was 40.5 on pre-test and 90.2 on post-test. The students responses get an average score of 93.3% which is categorized as very good. Therefore, student worksheet based on Problem Based Learning on bacteria toppic was valid, practical and effective to be used in learning activities.
