Geometry learning at the Junior High School (SMP) level frequently faces challenges due to the abstract nature of the objects, which impacts students' low spatial literacy. This issue is exacerbated by the dominance of conventional teaching methods that lack interactive digital media. This community service activity aims to enhance students' spatial literacy at SMP IT Qoshrul Muhajirin through learning assistance using ethnomathematics-based digibooks. The method employed consists of four stages: Planning, Acting, Observing, and Reflecting. Data were collected through observation, student response questionnaires, as well as pre-test and post-test instruments. The results indicate a significant improvement in students' spatial literacy by 22.70%, with the average score increasing from 43% in the initial stage to 65.70% following the assistance. Furthermore, 91.3% of students provided positive responses regarding the ease of use of the media, and 90.4% felt more motivated in learning. It can be concluded that the use of ethnomathematics-based digibooks is effective as an innovative learning solution capable of integrating digital technology with local cultural values to optimize students' spatial abilities.
