Abstract

Atomic structure is one of the materials studied in phase E SMA/MA. This material is abstract and very important for further chemistry material. Teaching materials that can help students understand the concept are needed. There has been an atomic structure e module that has been valid and very practical but has not been tested for its effectiveness on learning outcomes. This study aims to test the effectiveness of atomic structure e-modules on student learning outcomes. The type and design of the research is pre-experimental and one group Pretest-Posttest using purposive sampling. Based on the results of data analysis, the N Gain test results were 79% with effective, meaning that the e-module of atomic structure can effectively improve the learning outcomes of students.

Abstract

Reports of the chemical constituents of Andrographis paniculata showed that this plant produced various secondary metabolites with antibacterial activity. Further exploration of bioactive compounds from A. paniculata can also be conducted by analyzing its endophytic fungi. Isolation of endophytic fungi from the twig of A. paniculata obtained three isolates of endophytic fungi. One of the isolates, RS-2, was fermented on rice media and extracted with ethyl acetate to give the EtOAc extract. The EtOAc extract from fungus RS-2 was analyzed for their antibacterial and phytochemical screening. The results exhibiting the EtOAc extract of fungus RS-2 has activity to inhibite bacterial growth. Overall, the study of the antibacterial activity of endophytic fungus obtained from the twig of A. paniculata was firstly carried out in this study

Abstract

Stoikiometri merupakan salah satu materi kelas XI SMA/MA pada kurikulum merdeka. Materi ini dianggap sulit dipahami oleh peserta didik karena karakteristik materinya yang abstrak dan banyak perhitungan. Belajar mandiri perlu dilakukan untuk meningkatkan pemahaman peserta didik. Hal ini dapat dilakukan dengan memanfaatkan media sosial, sesuai dengan salah satu karakteristik peserta didik saat ini yaitu menyukai media pembelajaran menggunakan teknologi dengan format audio-visual. Media sosial efektif digunakan untuk belajar mandiri seperti TikTok. Belum ditemukan akun TikTok yang membahas tuntas materi stoikiometri untuk kelas XI SMA/MA. Oleh karena itu, penelitian ini ditujukan untuk mengembangkan media pembelajaran melalui TikTok pada materi stoikiometri serta mengungkap validitasnya. Jenis penelitian ini adalah Educational Design Research dengan model pengembangan Plomp yang dibatasi sampai prototipe II meliputi tahap preliminary research dan prototyping stage. Penelitian dilaksanakan di Departemen Kimia FMIPA UNP dan SMAN 9 Padang.  Subjek penelitian ini adalah dosen Kimia FMIPA UNP, guru kimia, dan peserta didik kelas XI SMAN 9 Padang. Data hasil validasi diolah dan dianalisis menggunakan rumus Aiken’s V. Hasil validasi menunjukkan media valid dengan nilai 0,86.

Abstract

Hukum-hukum dasar kimia merupakan materi pembelajaran kimia kelas X SMA/MA. Karakteristik materinya abstrak dan banyak hitungan, sehingga materi tersebut sulit dipahami peserta didik. Untuk memahami materi pelajaran ini dengan lebih baik, diperlukan belajar mandiri. TikTok adalah salah satu sumber belajar mandiri di media sosial yang dapat digunakan pada era modern. Penggunaan platform ini membantu memicu antusiasme dalam belajar karena mayoritas murid menggunakan TikTok. Namun, belum ditemukan akun yang menggunakan platform tersebut untuk membagikan media belajar tentang materi hukum dasar kimia. Oleh karena itu, penelitian dengan tujuan mengembangkan media belajar menggunakan platfrom TikTok pada materi hukum-hukum dasar kimia dan mengetahui kevalidan. Jenis penelitian ini adalah educational design research menggunakan model pengembangan Plomp. Dengan tahapan preliminary stage, prototyping stage, dan assesement phase. Penelitian ini dibatasi pada tahap prototype III. Data validasi dikumpulkan dengan menggunakan kuesioner validasi. Materi tersebut divalidasi oleh lima orang: dua guru kimia dan tiga dosen kimia. Formula Aiken's V digunakan dalam proses analisis data. Berdasarkan hasil pengujian media belajar, kategori valid menghasilkan nilai Aiken’s V rata-rata sebesar 0,88. Media belajar menggunakan TikTok sebagai sumber belajar mandiri yang valid dan dapat diterapkan pada materi hukum-hukum dasar kimia.
