The research method used is research and development (R&D) using the Bord and Gall model. This model includes 10 stages, namely 1) needs analysis, 2) planning, 3) initial product development, 4) product validation, 5) product revision, 6) main product trial, 7) product revision, 8) wide scale trial , 9) product revision, and 10) use and production. This research collects data through observation, interviews, documentation, and questionnaires (expert validation). These collection techniques will be analyzed to obtain final results.
