Abstract

Abstrak: Penerapan model pembelajaran diskusi kelas teknik buzz group bertujuan meningkatkan prestasi belajar siswa materi pokok hidrokarbon. Penelitian dilaksanakan pada kelas X SMAN 1 Gunungsari.  Fokus penelitian ini adalah nilai post-test yang dianalisis dengan uji-t. Diperoleh thitung sebesar 2,23. Nilai thitung dikonsultasikan pada ttabel dengan taraf signifikan 5% diperoleh ttabel 1,684. Nilai thitung..> ttabel sehingga penerapan model pembelajaran diskusi kelas  teknik buzz group berpengaruh secara signifikan terhadap prestasi belajar kimia siswa kelas X SMAN 1 Gunungsari.Kata kunci :   model pembelajaran diskusi kelas, teknik buzz group, prestasi belajar. Abstract: The implementation of Class Discussion model through buzz group technique, in increasing students’ achievement in Hydrocarbon materials. The research is conducted on first year students senior high school at SMAN 1 Gunungsari. The focus of this research was on the post-test which analyzed by using t-test.  It found t-count is 2.23. The value of t-count consults to t-table with 5 % of level significant found t-table is 1.684. The value of t-count > t-table, that the implementation of Class Discussion model through buzz group technique has a significant influence toward students’ achievement chemistry course in first year senior high school at SMAN 1 Gunungsari.Key words: class discussion model, buzz group technique, learning achievement.

Abstract

Abstrak: Tujuan penelitian ini untuk menyelidiki penerapan media demonstrasi kimia yang dimodifikasi untuk mengatasi miskonsepsi mahasiswa pada topik sel elektrokimia. Penelitian dilaksanakan menggunakan penelitian tindakan kelas berbasis lesson study yang dilaksanakan  selama 2 siklus, yaitu siklus I menggunakan metode konvensional dan siklus II media demonstrasi kimia yang dimodifikasi.Hasil penelitian menunjukan bahwa miskonsepsi mahasiswa pada topik sel elektrokimia terkait dengan konsep transfer elektron, pembawa muatan listrik dalam rangkaian luar/kawat penghantar, mekanisme aliran listrik dalam larutan elektrolit dan jembatan garam, serta mekanisme aliran elektron maupun aliran listrik dalam sel galvani. Penerapan media demonstrasi kimia yang dimodifikasi dapat meningkatkan pemahaman konsep. Hal ini terbukti adanya peningkatan persentase mahasiswa yang mampu memperbaiki miskonsepsi, yaitu: transfer elektron 15%, pembawa muatan listrik dalam rangkaian luar/kawat penghantar 34%, mekanisme aliran listrik dalam larutan elektrolit dan jembatan garam 20%, mekanisme aliran elektron maupun rangkaian aliran listrik dalam sel galvani 25% dan 18%Dari hasil penelitian ini dapat disimpulkan bahwa media demosntrasi kimia yang dimodifikasi dapat mengatasi miskonsepsi karena merupakan cara pembelajaran yang dapat menyajikan fenomena kimia pada tingkat makroskopis, submikroskopis dan simbolik.  Kata kunci: demonstrasi kimia dimodifikasi, miskonsepsi, sel elektrokimia

Abstract

This research aims to increase the chemistry literation of students through the Integrated Problem Based Learning Model with Ethno Chemistry Sasambo in Analytical Chemistry lecture. The subject of this research is all 86 students who are taking the Chemistry Analytical lecture. Meanwhile, the object is chemistry literation in several aspects such as content, context, competition, and attitude and the response of students toward conducting an Integrated Problem-Based Learning model with local culture in the salt production process. The research methodology used in this research is action class research in three cycles. Each cycle consists of planning, observation, and evaluation-reflection. Results of this work gained are: (1) Increase in students' chemistry literation from mid to high category that can be seen as cycle 1 is 62.8 as enough category, cycle 2 is 70.7 as enough category, and cycle three is 76.7 as high category. (2) Students' response shows that 95% of them stated that they are very interested and wanted more and vary integrated of local culture.
