Abstract

This study aims to develop a mobile-based graphic design learning media using the Interactive Demonstration approach and to evaluate its feasibility and effectiveness in improving students’ learning outcomes. The study employed a Research and Development (R&D) method using the Agile development model, which consists of requirements analysis, design, development, testing, and deployment. The product was implemented for Grade XI Graphic Design students at SMK Negeri 13 Medan. Product quality was evaluated through material expert validation, media expert validation, user acceptance testing, and Blackbox testing, while its effectiveness was measured using a pretest–posttest design analyzed through an Independent Samples t-test. The results indicate that the developed Android-based learning media functions properly across different devices and provides interactive features that support graphic design learning. Expert validation and user acceptance demonstrated that the media achieved a very high level of feasibility. Furthermore, students who used the mobile learning media achieved significantly higher learning outcomes than those who learned using conventional modules. These findings suggest that mobile-based learning media integrated with the Interactive Demonstration approach is both feasible and effective for supporting graphic design instruction in vocational education.

Abstract

COVID-19 yang berasal dari virus SARS-CoV-2, telah menjadi pandemi global sejak tahun 2020 dan menjadi endemik pada awal tahun 2023. Penelitian ini bertujuan untuk memodelkan penyebaran COVID-19 di Provinsi Sumatera Utara dengan menggunakan model SIR (Suspected, Infected, Removed). Model SIR yang dikembangkan oleh Kermack dan McKendrik digunakan untuk membagi populasi menjadi tiga kelompok: berpotensi terinfeksi (Suspected), terinfeksi (Infected) dan pulih/meninggal (Removed). Model matematika ini telah banyak digunakan dalam studi penyebaran COVID-19. Kajian ini menggunakan data yang diperoleh dari Kementerian Kesehatan RI selama kurun waktu 1 tahun 8 bulan, terhitung sejak Januari 2022 hingga September 2022. Data tersebut meliputi jumlah kasus COVID-19 dan status pasien di Provinsi Sumatera Utara. Dengan menggunakan model SIR, dimungkinkan untuk memprediksi penyebaran penyakit COVID-19 di antara penduduk di Sumatera Utara.
