Abstract

Penelitian ini bertujuan untuk mengetahui keterlaksanaan pembelajaran, keterampilan prdisini oses siswa dan ketuntasan hasil belajar kognitif produk siswa setelah penerapan model pembelajaran inkuiri pada materi pokok larutan penyangga. Jenis penelitian ini adalah deskriptif kuantitatif dan rancangan penelitian yang digunakan  adalah one shoot case study. Sasaran penelitian ini adalah siswa kelas XI SMA Mazraatul Ulum Paciran Lamongan. Instrument yang digunakan adalah lembar observasi keterlaksaan model pembelajaran inkuiri, lembar penilaian keterampilan proses, lembar soal tes keterampilan proses, dan lembar soal tes kognitif produk. Hasil penelitian menunjukkan bahwa (1) Persentase rata-rata keterlaksanaan model pembelajaran inkuiri pada pertemuan I sebesar 81,71% (sangat baik), pertemuan II sebesar 87,27% (sangat baik), dan pertemuan III sebesar 93,98% (sangat baik); (2) Nilai rata-rata keterampilan proses siswa sebesar 76 dengan ketuntasan klasikal siswa sebesar 72,41% (3) Ketuntasan klasikal hasil belajar kognitif produk siswa sebesar 86,20%.
