Pengembangan Lembar Kerja Siswa Berbasis Pendekatan Saintifik pada Materi Sistem Pernapasan di SMA Swasta Hoya Sejahtera

Penelitian ini bertujuan untuk mengembangan LKS Berbasis Pendekatan Saintifik Pada Materi Sistem pernapasan di SMA Swasta Hoya Sejahtera Kecamatan Somambawa Kabupaten Nias Selatan, berdasarkan tanggapan ahlizmateri, ahli media, dan ahlizbahasa. Metodezpenelitan ini menggunakan metode Research and Development (R&D). Desain penelitian dan pengembangan mengikuti desain penelitian dan pengembangan yang terdirizatas sepuluh langkah. Namun, Pada penelitianzinizhanya dibatasi sampai tujuhztahap, dikarenakan peneliti memiliki waktu yang sangat terbatas dan penyebaran penelitian ini juga sangat terbatas. LKS telah diuji kelayakannya oleh 3 orang validator ahli materi, 3 orang validator media, 3 orang validator ahli bahasa dan tanggapan 36 siswa terhadap Pengembangan LKS Berbasis Pendekatan Saintifik Pada Materi Sistem pernapasan di SMA Swasta Hoya Sejahtera Kecamatan Somambawa Kabupaten Nias Selatan. Hasil penelitian menunjukkan bahwa LKS Berbasis Pendekatan Saintifik pada Materi Sistem Pernapasan Manusia termasuk dalam kategori sangat layak, menurut ahli materi, ahli media dan ahli bahasa. Penilaian dari ahli materi memperoleh kelayakan dengan hasil rata-rata persentase 86% dengan kategori “sangat layak”. Penilaian ahli media memperoleh hasil rata-rata persentase 87% dengan kategori “sangat layak”. Penilaian ahli bahasa memperoleh rata-rata persentase 85% dengan kategori “sangat layak”, sedangkan siswa secara keseluruhan LKS berbasis pendekatan saintifik pada materi sistem pernapasan manusia memiliki rata-ratazpersentasezkelayakanzsebesarz86%zdengan kelayakan “sangat layak”.

This research method uses themethod Research and Development (R&D). The research and development design follows the research and development design which consists of 10 steps. However, in this study it was only limited to seven stages, because researchers had a very limited time and the spread of this research was also very limited. LKS has been tested for its feasibility by 3 material expert validators, 3 media validators, 3 linguist validators and 36 students' responses to the development of worksheets based on a scientific approach in respiratory system material at Hoya Sejahtera Private High School, Somambawa District, South Nias Regency. The results showed that worksheets based on a scientific approach to the material of the Human Respiratory System were in the very feasible category, according to material experts, media experts and linguists. The evaluation from material experts obtained eligibility with an average percentage of 86% in the "very feasible" category. The media expert's assessment obtained an average percentage of 87% with the "very feasible" category. The linguist's assessment obtained an average percentage of 85% with the "very feasible" category, while the overall student worksheets based on a scientific approach to the material of the human respiratory system had an average percentage of 86% with "very feasible" eligibility.
