Abstract :
Penelitian ini bertujuan untuk mengembangkan dan mengetahui kelayakan Lembar
Kerja Siswa (LKS) model Inquiry Based Learning (IBL) pada materi sel. Penelitian ini
merupakan penelitian dan pengembangan (Reseacrh and Development) menggunakan
model pengembangan yang dimodifikasi dari Jitu yang terdiri dari tahap menganlisis
kebutuhan (kebutuhan siswa, wawancara guru, dan silabus), merangcang media
pembelajaran, meminta saran dari pakar isi dan konstruk, revisi I, memvalidasi media
pembelajaran, revisi II, dan hasil produk. Instrumen dalam penelitian ini menggunakan
angket. LKS yang sudah selesai disusun diuji kelanyakan oleh reviewer terdiri dari ahli
materi, ahli bahasa, ahli media, angket tanggapan guru Biologi dan angket tanggapan
siswa kelas XI MIPA SMA Budi Warman 1 Jakarta Timur yang berjumlah 53 siswa.
Metode pengumpulan data dengan angket. Hasil penelitian yang telah dilakukan berupa:
1) dihasilkan LKS model Inquiry Based Leraning (IBL) pada materi sel kelas XI MIPA;
2) penilaian satu satu ahli materi diperoleh persentase rata-rata 87% dengan kategori
kelayakan ?Sangat Layak?. Penilaian satu ahli Bahasa diperoleh persentase rata-rata
85% dengan kategori kelayakan ?Sangat Layak?. Penilaian dari satu ahli media
diperoleh persentase rata-rata 90% dengan kategori kelayakan ?Sangat Layak?.
Penilaian oleh guru Biologi diperoleh persentase rata-rata 95% dengan kategori
kelayakan ?Sangat Layak?. Penilaian oleh 53 siswa diperoleh persentase rata-rata 75%
dengan kategori kelayakan ?Sangat Layak?. Berdasarkan data yang didapat, maka LKS
model Inquiry Based Learning (IBL) pada materi sel layak untuk dugunakan oleh siswa
kelas XI MIPA SMA Budi warman 1 Jakarta Timur./ The purposes of this research are to develop and determine the feasibility of Student
Worksheet inquiry-based learning models on cell material. This research is research and
development using a modified development model from Jitu which consists of the stage
of analyzing needs (student needs, teacher interviews, and syllabus), designing learning
media, asking for advice from content and construct experts, revision I, validating
learning media, revising II, and product results. The instrument in this study using
questionnaire. The worksheets that had been compiled were tested for questioning by
reviewers consisting of material experts, linguists, media experts, Biology teacher
responses questionnaires and student XI MIPA high school Budi Warman 1 high school
students in East Jakarta, totaling 53 students. Data collection method with a
questionnaire. The results of research conducted in the form of: 1) generated LKS
inquiry-based learning model) on cell material class XI MIPA; 2) assessment of one
material expert obtained an average percentage of 87% with the category of "Very
Eligible". One linguist's assessment obtained an average percentage of 85% in the "Very
Eligible" category. An assessment from one media expert obtained an average
percentage of 90% with the category of "Very Eligible". An assessment by a Biology
teacher obtained an average percentage of 95% with the "very Eligible " category.
Assessment by 53 students obtained an average percentage of 75% with the category of
"Very Eligible". Based on the data obtained, the LKS inquiry-based learning model on
cell material is suitable for use by students of class XI of Mathematics and Natural
Sciences Budi Warman 1 East Jakarta.
Keywords: development, LKS inquiry-based learning model, feasibility, cells.
