This study developed the Ethno Mandailing-Realistic Mathematics Education (Ethno Mandailing-RME) Model, assisted by Adobe After Effects, to improve elementary school students' numeracy literacy skills by integrating local Mandailing culture, especially Bagas Godang and Sopo Godang, into realistic mathematics learning through visual animation media. The study used a research and development approach based on the Plomp model, which includes the initial investigation, design, development, implementation, and evaluation stages, involving 125 fifth-grade students from three public elementary schools in Mandailing Natal Regency, comprising 69 students in the experimental class and 56 in the control class. The results of expert validation showed that the developed model was in the very valid category with an average score of 4.58. At the same time, the practicality aspect was reflected in the high teacher response rate (91%), student response rate (89%), and learning implementation rate (93%). The effectiveness test showed that the experimental class achieved higher average posttest and N-Gain scores than the control class, and statistical analysis confirmed a significant difference in numeracy literacy improvement. Thus, the Ethno Mandailing-RME Model, assisted by Adobe After Effects, has been proven valid, practical, and effective in improving numeracy literacy skills among elementary school students.
