This study aims to produce a Roadmap that shows the relationship between the needs of what mathematics materials are needed in the electrical engineering department and roadmap-based applied mathematics textbooks that meet valid, practical and effective criteria to improve student mathematics learning outcomes. This study uses the Ploom development model by dividing the development stage into three phases. Test the validity of the Rodmap mathematics flow chart and Roadmap-based learning books developed through the self-evaluation stage and the expert assessment stage (1 mathematics expert, 1 electrical engineering expert, 1 language expert and 1 educational technology expert). Practicality tests are carried out to students in the electrical engineering department of UNP as users of Roadmap-based textbooks and effectiveness tests are carried out to students after using Roadmap-based textbooks. The results showed that the Roadmap validity test obtained an assessment of 3.76 with a very valid category, then the Roadmap-based textbook validity test by obtaining a score of 3,179 textbook practicality tests by small group stage students obtained an assessment of 88. 44% and the effectiveness test of the Small Group stage student learning outcomes test obtained 100% with the very effective category. Thus it can be concluded that the development of the roadmap design developed obtains results with valid, practical and effective categories to improve learning outcomes.
