Penelitian yang berjudul “Pengembangan Lembar Kerja Siswa (LKS) Praktikum Inkuiri Terbimbing Pada Sifat-Sifat Penyangga Obat Tetes Mata” bertujuan untuk membuat LKS praktikum berbasis inkuiri terbimbing. Langkah penelitian yang dilakukan yaitu tahap pengembangan dan tahap validasi. Sumber data pada penelitian ini adalah LKS praktikum dalam 10 buku kimia SMA kelas XI yang beredar, siswa kelas XI di salah satu SMA di Kota Cimahi, 3 orang dosen Departemen Pendidikan Kimia FPMIPA Universitas Pendidikan Indonesia, dan 2 orang guru kimia SMA. Instrument penelitian yang digunakan adalah indikator keterampilan inkuiri, lembar analisis LKS komtekstual, lembar penilaian kesesuaian LKS dengan konsep, lembar penilaian tata bahasa dalam LKS yang dikembangkan, lembar indikator ketercapaian keterampilan inkuiri, lembar observasi keterlaksanaan tahapan inkuiri, pedoman jawaban siswa terhadap tugas-tugas dalam LKS yang dikembangkan, serta angket respon siswa. Hasi penelitian pada tahap pengembangan menunjukkan bahwa dari 7 LKS dalam 10 buku kimia SMA kelas XI rata-rata hanya memiliki ketercapaian indikator keterampilan inkuiri sebesar 21,43% dan tidak ada LKS yang bersifat kontekstual. Keterlaksanaan praktikum menggunakan LKS yang dikembangkan tergolong baik sekali 98,59%. Berdasarkan penilaian guru dan dosen terhadap LKS praktikum yang dikembangkan tergolong baik sekali 91,77%.
