Perancangan Aplikasi Pembelajaran Bahasa Inggris Berbasis Multimedia Menggunakan Metode Multimedia Development Life Cycle

English learning for 7th-grade students at SMP Swasta Nommensen currently faces several obstacles due to conventional teaching methods that rely on printed textbooks and expository lectures without digital interactive media support. This study aims to design and build a web-based English learning application integrated with four multimedia pillars (text modules, native speaker pronunciation audio, situational animation videos, and timed evaluation quizzes) using the Multimedia Development Life Cycle (MDLC) method. System modeling was constructed using Unified Modeling Language (UML) diagrams and a 3NF relational database. Testing was conducted through Black-Box Testing and media feasibility evaluations involving Subject Matter Experts, Media Experts, and 72 seventh-grade student respondents using 5-point Likert Scale questionnaires. The results show that the Black-Box testing achieved 100% functionality without logic errors. Feasibility evaluations yielded 92.00% from the Subject Matter Expert (Very Feasible), 96.00% from the Media Expert (Very Feasible), and an average acceptance score of 74.69% (Feasible) from the 72 student respondents, resulting in an overall average score of 87.56% (Very Feasible). Thus, this multimedia learning application is proven to be valid, reliable, and highly suitable to be implemented as a supplementary learning tool for English subject
