Abstract
Penelitian iniÃÂ merupakan penerapan model pembelajaran kooperatif berbasis demonstrasi kimia yang dimodifikasiÃÂ untuk meningkatkan pemahaman konsep kimia analitikÃÂ dan karakter mahasiswa.Penelitian ini menggunakan rancangan penelitian tindakan kelas (PTK) yang dilaksakan selama 4 siklus. Tahapan penelitian meliputi perencanaan, pelaksanaan tindakan, observasi, analisis dan refleksi. Subyek dalam penelitian ini adalah Mahasiswa Progdi. Pendidikan Kimia yang mengikuti matakuliah dasar dasar kimia aanalitik. Obyek penelitian ini adalah pemahaman mahasiswa pada konsep kimia analitik dan karakter kerja keras dan tanggung jawab.
Hasil penelitian menunjukkan bahwa nilai rata-rata pemahaman konsep kimia analitik mahasiswa pada siklus I (titrasi asam basa) sebesar 57,5ÃÂ siklus II (aplikasi titrasi asam basa) sebesar 65, siklus III (Titrasi pengendapan) sebesar 70, dan siklus IV (aplikasi titrasi pengendapan) sebesar 75. Peningkatan nilai karakter tanggung jawab adalah sebagai berikut: cukup (siklus I), baik (siklus II), baik (siklus III) dan sangat baik (siklus IV). Sedangakan untuk nilai karakter kerja keras mahasiswa adalah: cukup (siklus I), cukup (siklus II), baik (siklus III), dan baik (siklus IV).
Kesimpulan penelitian ini menunjukan bahwa penerapan model pembelajaran kooperatif berbasis demonstrasi kimia yang dimodifikasi dapat meningkatkan pemahaman konsep kimia analitik dan nilai karakter tanggung jawab dan kerja keras padaÃÂ mahasiswa.
