Pengambilan sampel Uji coba skala besar tersebut secara convenience sample. Hasil penelitian ini meliputi data kualitatif dan data kuantitatif. Data kualitatif diperoleh dari instrumen penilaian kelayakan LKS tahap I sebesar 100%, tahap II yaitu, penilaian kelayakan isi materi 96,87%, penilaian kelayakan kebahasaan 84,62%, penilaian kelayakan penyajian 73,68%, serta angket tanggapan guru 75% dan angket tanggapan siswa 77,90%. Data kuantitatif diperoleh dari hasil belajar siswa setelah proses pembelajaran yaitu Tes evaluasi 8,67% dengan standar KKM 7,00. Dari hasil penelitian dapat disimpulkan bahwa LKS berpendekatan JAS materi ekosistem kelas VII layak dan dapat dikembangkan untuk pembelajaran. Abstract ___________________________________________________________________ This research was conducted to determine the feasibility of worksheet based on approach JAS to be developed as a learning material as well as discovering the response of teachers and students on the use of worksheet based on JAS as teaching materials. The research method used is Research and Development (R&D) which includes several stages: problem identification, data collection, product design, design validation by experts, correction , small-scale trials, product revisions, large-scale trials, revision products, and final products. The large-scale sampling is done by convenience sampling. Results of this study include qualitative data and quantitative data. The qualitative data is obtained from the feasibility assessment instruments LKS phase I of 100%, phase II, feasibility assessment materials 96.87%, the assessment linguistic appraisal criteria was 84.62%, the assessment of presentation expendience 73, 68%, as well as the questionnaire responses of 75% of teachers and students' questionnaire responses of 77.90%. Quantitative data is obtained from the results of student's learning after the learning process of evaluation tests at 8.67%. of standart KKM 7,00. From the results of this study. It is concluded that the worksheet based JAS material class VII ecosystem is feasible and able to develop for learning.
