ANALISIS POTENSI LKS PRAKTIKUM PADA TOPIK TITRASI ASAM-BASA BERBASIS INKUIRI TERBIMBING UNTUK MENGEMBANGKAN KETERAMPILAN PROSES SAINS

Penelitian ini bertujuan untuk menganalisis potensi LKS praktikum pada topik titrasi asam-basa berbasis inkuiri terbimbing untuk mengembangkan keterampilan proses sains. Metode penelitian yang digunakan adalah penelitian deskriptif kualitatif. Objek penelitian yaitu LKS praktikum berbasis inkuiri terbimbing pada penentuan konsentrasi asam klorida dalam pembersih keramik hasil pengembangan Risnawati (2016). Partisipan dalam penelitian ini adalah tiga orang dosen pendidikan kimia dan dua orang guru mata pelajaran kimia. Instrumen penelitian berupa lembar penilaian kesesuaian tahapan inkuiri terbimbing dengan indikator dan sub-indikator keterampilan proses sains, penilaian kesesuaian isi dalam LKS dengan indikator dan sub-indikator keterampilan proses sains dan penilaian analisis potensi LKS untuk mengembangkan keterampilan proses sains. Hasil penelitian menunjukkan tahapan inkuiri terbimbing memiliki kesesuaian dengan indikator dan sub-indikator keterampilan proses sains dengan kategori sangat baik dan isi dalam LKS praktikum memiliki kesesuaian dengan indikator dan sub-indikator keterampilan proses sains dengan kategori sangat baik, serta LKS praktikum pada topik titrasi asam-basa berbasis inkuiri terbimbing berpotensi mengembangkan seluruh indikator keterampilan proses sains yaitu mengamati/observasi, mengelompokkan/klasifikasi, menafsirkan/ interpretasi, meramalkan/prediksi, mengajukan pertanyaan, mengajukan hipotesis, merencanakan percobaan/penyelidikan, menggunakan alat/bahan/sumber, menerapkan konsep, melakukan komunikasi dan melaksanakan percobaan/penyelidikan. Kata kunci: Keterampilan Proses Sains, LKS Praktikum Berbasis Inkuiri Terbimbing, Titrasi Asam-Basa This research aims to analyze the potential of practicum worksheets on the topic of guided inquiry-based acid-base titration to develop science process skills. The research method used is descriptive qualitative research. The object of research is the guided inquiry-based practical worksheets in determining the concentration of hydrochloric acid in tile cleaner developed by Risnawati (2016). Participants in this study were three chemistry education lecturers and two chemistry teachers. The research instrument included the guided inquiry stage suitability assessment sheet with indicators and sub-indicators of science process skills, assessment of content suitability in student worksheets with indicators and sub-indicators of science process skills, assessment of analysis the potential of student worksheets to develop science process skills. The results of the assessment show that the guided inquiry stage had a very good agreement with the indicators and sub-indicators of science process skills and the content in practicum student worksheets corresponds to the indicators and sub-indicators of science process skills in a very good category, as well as practicum worksheets on the topic of guided inquiry-based acid-base titration has the potential to develop all indicators of science process skills namely observing, classifying, interpreting, predicting, asking questions, proposing hypotheses, planning experiments/investigations, using tools/ materials/sources, applying concepts, communicating and conducting experiments.
