Abstract

This study elucidates the role of secondary metabolites in green betel leaves (Piper betle) as antibacterial agents against Bacillus cereus, a bacterium causing various foodborne illnesses in humans. The experimental research was conducted at the Biology Laboratory, Faculty of Mathematics and Natural Sciences, Universitas Negeri Medan, utilizing Bacillus cereus bacterial isolates and extracting betel leaves using water. The measurement of inhibition zones was performed to evaluate the antibacterial activity of the betel leaf extract. The research results indicate the presence of an inhibition zone against Bacillus cereus growth, albeit categorized as weak. The measurements varied across repetitions, namely 2.6 mm, 3.35 mm, and 1.05 mm. The average of these three results was 3 mm.

Abstract

This study aims to develop and evaluate the “Environmental Monopoly” learning media based on QR Code technology to enhance students’ science literacy on environmental pollution material. The methods used include validation by subject matter experts and education practitioners, as well as feasibility testing with students. The results indicate that this media has good feasibility with validation scores of 72.5% for content feasibility, 75% for presentation, and 68.75% for language. Trials in seventh-grade classes showed that 92% of students felt more active, 85% showed improved understanding of the material, and 88% expressed satisfaction with the use of this media. These results suggest that “Environmental Monopoly” can be an effective and innovative learning tool to improve students’ science literacy.

Abstract

Penelitian ini bertujuan untuk mengembangkan permainan monopoli berbantuan teknologi QR Code sebagai media pembelajaran IPA pada topik keanekaragaman hayati Indonesia. Penelitian dilakukan di SMP Negeri 27 Medan. Model pengembangan yang digunakan dalam penelitian ini adalah ADDIE, yang mencakup tahapan Analyze, Design, Development, Implementation, dan Evaluation. Media monopoli ini divalidasi berdasarkan tiga aspek: materi, media, dan asesmen. Hasil validasi dari ahli materi memperoleh skor 85,38% (sangat layak), ahli media memperoleh skor 91,54% (sangat layak), dan ahli asesmen memperoleh skor 93,3% (sangat layak), dengan rata-rata keseluruhan validasi sebesar 90,74%. Respons guru menunjukkan skor tertinggi pada aspek visual (93,75%), sedangkan respons siswa menunjukkan skor kelayakan keseluruhan sebesar 91,13%, dengan aspek keterarikan memperoleh skor tertinggi sebesar 93,12%.

Abstract

This research aims to develop a monopoly game integrated with QR Code technology as a science learning media on Indonesian biodiversity topic. The Monopoly media was designed to be suitable and effective for junior high school science courses, specifically at SMP Negeri 27 Medan. The development process follows the ADDIE (Analyze, Design, Development, Implementation, and Evaluation) model with data analysis techniques from validation sheets (content, media, and assessment) and teacher and student assessments presented in the form of a summary list using a likert scale (maximum 5 and minimum 1) which is then interpreted qualitatively. Validation results showed high feasibility scores of 85.38% from content experts, 91.54% from media experts, and 93.3% from assessment expert. Teacher responses also indicated the score average value of 90.62%, while student responses showed an overall feasibility score of 91.13%, with attractiveness receiving the highest rating at 93.12%.
