Summary

Penelitian ini bertujuan untuk mengembangkan perangkat pembelajaran praktikum pemisahan campuran teknik sublimasi dengan melakukan penelitian kelompok dengan pendekatan saintifik untuk meningkatkan keterampilan berpikir kritis dan mendeskripsikan kelayakan perangkat pembelajaran praktikum. Dalam penelitian ini, keterampilan berpikir kritis siswa yang diukur dilihat dari lima aspek sesuai indikator Inch (2006), yaitu: tujuan, pertanyaan terhadap masalah, asumsi, informasi dan konsep. Kelayakan dari perangkat praktikum sublimasi dilihat dari tiga aspek- validitas, kepraktisan dan keefektifan. Perangkat praktikum bersama perangkat pembelajaran (perangkat praktikum, RPP dan LKS) dengan lembar observasi dan kuesioner dikembangkan dengan Penelitian & Pengembangan (R&D) berdasarkan Borg and Gall. Perangkat praktikum kemudian dinilai dengan uji coba terbatas, uji coba luas dan penelitian kelas pada tiga sekolah swasta di Bandung. Pengembangan perangkat kemudian dinilai dan divalidasi oleh ahli (untuk aspek validitas), implementasi dari perangkat pembelajaran praktikum di observasi oleh observer (untuk aspek kepraktisan dan keefektifan). Kemudian dilakukan analisis kuantitatif dan dideskripsikan secara kualitatif. Hasil dari penelitian menunjukkan bahwa pengembangan perangkat praktikum sublimasi dinyatakan layak secara validitas, kepraktisan dan keefektifitasan. Perangkat praktikum dinyatakan valid berdasarkan penilaian ahli, dinyatakan praktis dan efektif ketika diimplementasikan di kelas praktikum pemisahan campuran teknik sublimasi, serta dapat meningkatkan keterampilan berpikir kritis siswa; The research aimed to develop practicum device of separation mixtures with sublimation techniques by conducting group investigation of scientific approach to increase students' critical thinking skills and describe their feasibility. In this research, students' critical thinking skills were judge by five indicators based on Inch (2006), there are: pupose, question at issue, assumption, information and concept. Then, the intended feasibility includes three aspects-validity, practicality, and effectiveness aspect. The practicum device accompanied with teaching materials (i.e., syllabus, lesson plan, students' books, and students' worksheets) were developed using Research & Development methods as proposed by Borg and Gall. The practicum device developed were used for the 7th grade students at three private junior high school in Bandung. The developed device were further assessed and validated by an expert (for validity aspect), the implementation of the practicum device in the class were observed by a number of observers (for practicality and effectiveness aspects). The results then were analyzed quantitatively and described qualitatively. The findings of the research showed that the developed practicum device of sublimation experiment were feasible because of their validity, practicality, and effectiveness. This means that the device were valid according to the expert's judgments, were practical and effective when implemented in the sublimation separation of mixtures experiment learning process, and were able to increase students' critical thinking skills.
