Abstract


Tujuan penelitian ini untuk mengetahui kelayakan Lembar Kegiatan Siswa (LKS) pada materi Kesetimbangan Kimia dan respon siswa SMA. Sumber data diperoleh dari tim ahli meliputi dosen dan guru kimia sebagai penelaah dan validator. Rancangan penelitian ini adalah Research and Development (R&D), tetapi hanya dibatasi sampai tahap uji coba terbatas. Uji coba terbatas dilakukan terhadap 15 siswa kelas XI IPA 6 SMA Negeri 15 Surabaya. Instrumen penelitian yang digunakan berupa lembar telaah, lembar validasi, dan lembar angket. Analisis data dilakukan secara deskriptif kualitatif untuk hasil telaah dan deskriptif kuantiatif untuk hasil validasi terhadap kelayakan LKS serta respon siswa. Hasil penelitian menunjukkan bahwa LKS yang dikembangkan telah layak digunakan karena memenuhi kelayakan berdasarkan hasil validasi kriteria kesesuaian terhadap komponen Open-Ended Problem Solving dengan persentase 83,33%; kriteria kesesuaian dengan multiple representations dengan persentase 89,59%; kriteria isi dengan sebesar 88,92%; kriteria penyajian dengan persentase 92,32%; kriteria kebahasaan dengan persentase 87,50%; dan kriteria kegrafisan dengan persentase 89,72%. Persentase respon siswa untuk kriteria kesesuaian terhadap komponen Open-Ended Problem Solving dengan persentase 89,33%; kriteria kesesuaian dengan multiple representations dengan persentase 82,22%; kriteria isi dengan persentase 80%; kriteria penyajian dengan persentase 83,33%; kriteria kebahasaan dengan persentase 80%; dan kriteria kegrafisan dengan persentase 88,33%.

The aims of this research are to know the feasibility of student worksheet in Chemical Equilibrium matter and response of Senior High School students. The sources of data are resulted by lecturer and teacher of chemistry as reviewer and validator. Research design uses Research and Development (R&D) method but limited until limited trial step. The limited trial is conducted by 15 students of XI IPA 6 SMA Negeri 15 Surabaya. Research instruments are review sheet, validation sheet, and questionnaire sheet. Data analysis was done by qualitative descriptive for the result of student worksheet review and quantitative descriptive for the percentages of assessment result from validator and also from response of students. The result has showed that the student worksheet fulfilled the feasibility criteria for suitability with component of Open-Ended Problem Solving with percentage 83.33%; suitability with multiple representations with percentage 89.59%; content with percentage 88.92%; presentation with percentage 92.32%; language with percentage 87.50%; and graph with percentage 89.72%. The percentages of student response have fulfilled the feasibility criteria for suitability with component of Open-Ended Problem Solving with percentage 89.33%; for suitability with multiple representations with percentage 82.22%; content with percentage 80%; presentation with percentage 83.33%; language with percentage 80%; and graph with percentage 88.33%
Keywords: student worksheet, multiple representation, open-ended, problem solving, chemical equilibrium, feasibility
