THE DEVELOPMENT OF GUIDED INQUIRY-ORIENTED BILINGUAL WORKSHEET TO REHEARSE SCIENCE CHARACTER VALUE ON FACTORS THAT AFFACTED REACTION RATE TOPIC

Penelitian ini bertujuan untuk mengetahui kelayakan Lembar Kerja Siswa (LKS) bilingual berorientasi inkuiri untuk melatihkan nilai karakter sains pada materi faktor-faktor yang mempengaruhi laju reaksi yang diujicobakan secara terbatas di SMA Negeri 1 Manyar. Karakter sains yang dikaji dalam pengembangan LKS ini adalah disiplin, ingin tahu, teliti, jujur dan tanggung jawab. Rancangan penelitian menggunakan rancangan Penelitian dan Pengembangan dimana pada studi pengembangan dilakukan model pengembangan Thiagarajan (model 4D) yang hanya dilakukan sampai tahap pengembangan (development). Rancangan LKS ditelaah oleh 3 orang dosen kimia Universitas Negeri Surabaya dan di validasi oleh 3 orang dosen kimia Universitas Negeri Surabaya dan 1 orang guru Kimia SMA Negeri 1 Manyar. Hasil penelitan menunjukkan bahwa LKS yang dikembangkan layak digunakan sebagai  salah satu sumber belajar. Penilaian dosen dan guru kimia terhadap LKS sangat layak dengan presentase kriteria isi sebesar 90,63%, kesesuaian dengan model pembelajaran inkuiri sebesar 80,68%, kriteria penyajian sebesar  89,29%, kriteria kebahasaan sebesar 82,81% dan kriteria kegrafikan sebesar 86,61%.  Respon siswa terhadap LKS sangat layak dengan presentase sebesar 96,67%. LKS juga dapat melatihkan nilai karakter sains kepada siswa antara lain disiplin, ingin tahu, teliti, jujur, dan tanggung jawab dengan presentase kelima karakter adalah 80%-100%. Kata Kunci: Pengembangan Lembar Kerja Siswa (LKS), Pembelajaran Inkuiri, Nilai Karakter Sains The objective of this study was known the feasibility of bilingual worksheet with guided inquiry-oriented to rehearse science character value on topic of factors that affected on reaction rate. The bilingual worksheet has been tested to the limited group in SMA Negeri 1 Manyar. Science character in this experiment are discipline, curiosity, accurate, honest and responsibility. Design of this study used research and development design in which on development step used 4-D model by Thiagarajan. This step is only done through the development stage (development). This worksheet was analyzed by 3 chemistry lecturer of Surabaya State University and 1 chemistry teacher of SMA Negeri 1 Manyar. The result of this research show that bilingual worksheet which is developed is feasibility to be used as learning resource. Validation result toward Lecture toward bilingual worksheet by chemistry lecturer and teacher is very good with percentage of content criteria is 90.63%, suitability of guided inquiry learning model is 80.68%, presenting criteria is 89.29%, language criteria is 86.61%. Students responses for bilingual worksheet is very good with percentage is 96.67%. Bilingual worksheet can also rehearse science character value that are discipline, curiosity, accurate, honest and responsibility with all of science characters in this study the percentage is 80%-100%.
