Abstract

Kurikulum SMALB terdiri atas bidang akademik dan keterampilan. Keduanya dapat diajarkan melalui pembelajaran berorientasi kewirausahaan. Kewirausahaan yang diintergrasikan kedalam materi kimia dapat dilakukan dengan mengembangkan LKS berorientasi chemo-entrepreneurship. Tujuan penelitian mengembangkan LKS chemo-entrepreneurship yang layak untuk melatihkan kemampuan entrepreneur siswa tunarungu. Jenis penelitian adalah Research and Development (R&D). Instrumen penelitian terdiri atas lembar telaah, lembar validasi, lembar observasi aktivitas, lembar tes, dan angket respon. Sumber data ialah 1 dosen kimia, 1 dosen PLB, 1 guru IPA SMALB, dan 6 siswa tunarungu SMALB Karya Mulia. Teknik pengumpulan data terdiri atas angket, observasi, dan tes kemudian dianalisis secara deskriptif. LKS dikatakan layak dengan kriteria baik atau sangat baik jika memperoleh persentase ≥69% untuk kelayakan secara teoritis, dan ≥61% dengan kriteria baik atau sangat baik untuk kelayakan secara empiris. Kelayakan teoritis ditinjau dari hasil validasi meliputi kriteria isi, kebahasaan, penyajian, dan kegrafisan dengan rentang persentase tiap-tiap kriteria adalah 80,00% – 93,33%; 80,00% – 93,33%; 80,00% – 93,33%; dan 80,00% – 86,67%, sehingga secara teoritis LKS dikatakan layak dengan kriteria baik dan sangat baik.

Type of research is Research and Development (R&D). The research instrument consisted of study sheet, validation sheet, observation activity sheet, test sheet, and student questionnaire. Data resource are 1 chemistry lectures, 1 PLB lecture, 1 science teacher in SMALB, and 6 students with hearing impariment in SMALB Karya Mulia. Technique of data collection consist of study, validation, observation, and test then analysed by descriptive. Students activity sheet proper if get percentage ≥69% with good or very good criteria for theoretic advisability, and  ≥69% with good or very good criteria for empiric advisability.
