Abstract

Kurangnya peran serta siswa dalam kegiatan pembelajaran menyebabkan siswa cepat jenuh sehingga dapat memperlambat tercapainya tujuan pembelajaran, salah satu tujuan pembelajaran kimia adalah kemampuan berkomunikasi. Pembelajaran yang dilakukan secara berkelompok dapat menimbulkan dampak yang negatif yaitu siswa hanya mengandalkan anggota dalam kelompoknya, sehingga tidak seluruh anggota kelompok berkontribusi dalam pembelajaran. Kondisi inilah yang menyebabkan kurangnya kemampuan berkomunikasi siswa. Penelitian ini bertujuan untuk memperoleh informasi tentang efektifitas MPKTGI terhadap kemampuan berkomunikasi siswa pada topik titrasi asam-basa semester dua di salah satu SMA Swasta di daerah Bandung. Metode penelitian yang digunakan adalah quasi experiment dengan desain penelitian pretest-postest control group design. Subjek penelitian terdiri dari 31 siswa kelas XI di kelas eksperimen dan 35 siswa di kelas kontrol. Hasil penelitian menunjukkan bahwa seluruh tahapan MPKTGI terlaksana sesuai dengan tahapan model pembelajaran tersebut. Kemampuan berkomunikasi siswa di kelas eksperimen lebih besar daripada kemampuan siswa di kelas kontrol, ditunjukkan dengan hasil uji statistika (uji-t) bahwa pada taraf signifikansi 0,05 terdapat perbedaan kemampuan berkomunikasi siswa yang signifikan pada topik titrasi asam-basa melalui penerapan MPKTGI. Selain itu, peningkatan kemampuan berkomunikasi siswa kelas eksperimen lebih tinggi dibandingkan dengan kelas kontrol dan siswa memberikan respon positif terhadap model pembelajaran ini.

Abstract

Peningkatan kualitas sumber daya manusia merupakan komitmen bersama yang harus dilakukan oleh berbagai elemen baik pemerintah maupun masyarakat. Meningkatkan kualitas sumber daya manusia berarti membekalinya dengan berbagai keterampilan dan kompetensi. Kemampuan tersebut dapat dimiliki melalui berbagai kegiatan baik kegiatan belajar maupun berlatih yang didukung dengan berbagai elemen. Keterbatasan guru terhadap lierasi dan juga kemampuan berfikir kritis, terkadang menjadikan pembelajaran kimia lebih bersifat teoritis, dimana hal ini diduga menjadi salah satu penyebab  rendahnya minat dan motivasi siswa untuk mempelajari kimia. Pengabdian Pada Masyarakat (P2M) tentang workshop pendalaman materi kimia karbon melalui Probleme based learning (PBL) dilakukan secara daring maupun luring dengan scenario setara 32 jp, yaitu 8 jp luring dan 24 jp daring. Adapun wilayah sasaran kegiatan P2M adalah MGMP kimia wilayah Pangandaran bekerjasama dengan guru-guru yang tergabung dalam MGMP Kabupaten Pangandaran, Kabupaten Ciamis, dan Kota Banjar. Adapun hasil yang diperoleh dari kegiatan P2M ini adalah analisis kurikulum dari beberapa sub-topik kimia karbon antara lain senyawa hidrokarbon, makromolekul senyawa organik, benzena, dan asam karboksilat. Selain analisis kurikulum peserta juga melakukan analisis konsepsi, analisis miskonsepsi, serta strategi pemblejaran menggunakan model PBL. Pada kegiatan ini guru-guru kimia kedepannya sangat membutuhkan workshop yang bertemakan pembelajaran berbasis PBL.Improving the quality of human resources is a joint commitment that must be carried out by various elements, both government and society. Improving the quality of human resources means equipping them with various skills and competencies. These abilities can be possessed through various activities, both learning and practicing activities that are supported by various elements. The teacher's limitations on literacy and critical thinking skills sometimes make chemistry learning more theoretical, which is thought to be one of the causes of the low interest and motivation of students to study chemistry. Community Service (P2M) regarding workshops on deepening carbon chemistry through problem based learning (PBL) conducted online and offline with a scenario equivalent to 32 jp, namely 8 jp offline and 24 jp online. The target area for P2M activities is the Pangandaran chemistry MGMP in collaboration with teachers who are members of the Pangandaran Regency, Ciamis Regency, and Banjar City MGMP. The results obtained from this P2M activity are curriculum analysis of several sub-topics of carbon chemistry, including hydrocarbon compounds, macromolecules of organic compounds, benzene, and carboxylic acids. In addition to curriculum analysis, the participants also carried out conceptual analysis, misconception analysis, and learning strategies using the PBL model. In this activity, future chemistry teachers really need workshops with the theme of PBL-based learning.
