Implementasi Metode Jeopardy Capture The Flag Sebagai Media Pembelajaran Cyber Security Berbasis Website (Studi Kasus: Kompetensi Keahlian TJKT SMK Negeri 1 Wanayasa)

This study addresses the need for practical cybersecurity learning media for vocational students, particularly in the Computer and Network Engineering (TJKT) program. The research aimed to develop and evaluate SkawanCTF, a website-based learning platform that applies the Jeopardy Capture The Flag (CTF) approach. The platform was developed using the Research and Development method with the Four-D model, consisting of Define, Design, Develop, and Disseminate. System requirements and workflows were designed using Unified Modeling Language, while implementation used Next.js, Tailwind CSS, Supabase, and Vercel. Functional testing was conducted using Black Box and White Box approaches. Learning outcomes were evaluated through pre-test and post-test scores, while user perceptions were collected using a five-point Likert questionnaire. The evaluation involved 168 students. The total pre-test score was 995 and the post-test score was 1,602, producing an N-Gain value of 0.8861 (88.61%), categorized as high. User perception reached an average score of 3.88, categorized as agree. The reported functional tests passed all tested scenarios across 37 modules. These findings indicate that SkawanCTF can operate as an accessible practice medium and received positive responses from participating students. Further evaluation with comparison groups and validated instruments is recommended.
