Abstract

ABSTRAKPenelitian ini bertujuan untuk: (1) mendeskripsikan karakteristik, (2) validitas, dan (3) keterbacaan Lembar Kerja Siswa (LKS) dengan model dscovery learning pada pokok bahasan titrasi asam basa. Jenis penelitian ini adalah penelitian pengembangan dengan tahapan penelitian yang diadaptasi oleh Sugiyono. Tahap penelitian yang dilakukan adalah pengumpulan data, desain produk, validasi desain, revisi desain, uji coba lapangan terbatas, dan revisi produk. LKS yang dikembangkan terdiri dari dua subtopik bahasan yaitu titrasi asam basa dan kurva titrasi. Karakteristik LKS dengan model discovery learning pada pokok bahasan titrasi asam basa, yaitu (1) menggunakan sintak discovery learning dan (2) menyajikan fenomena/gambar yang spesifik. Validasi LKS melibatkan satu orang ahli isi, satu orang ahli desain dan media pembelajaran, satu orang ahli bahasa, dan satu orang praktisi. Uji coba terbatas melibatkan 9 siswa kelas XI SMAN 2 Negara. Hasil validasi menunjukkan bahwa LKS yang dikembangkan telah memenuhi kategori valid. Berdasarkan hasil uji keterbacaan oleh siswa diperoleh tingkat keterbacaan yang baik.  ABSTRACT       This study aimed to (1) describe the characteristics, (2) the validity, and (3) the readability of Student Worksheets (LKS) with discovery learning models in the acid base titration topic. This type of research is research and development with the research stages adapted by Sugiyono. The stages of the research conducted are data collection, product design, design validation, design revision, limited field trials, and product revisions. The developed worksheet consisted of two subtopics, namely acid base titration and titration curve. Characteristics of LKS with discovery learning models in the acid base titration topic, namely (1) using discovery learning syntax and (2) presenting a specific phenomenon/image. LKS validation involves one content expert, one design and learning media expert, one linguist, and one practitioner. Limited trials involving 9 students of class XI of SMAN 2 Negara. The validation results show that the developed LKS has meets the valid category. Based on the results of the readability test by students obtained a good level.
