The purpose of this research is to create an animation-based learning media of corrosion processes in the subject of Corrosion and Coating at the Department of Mechanical Engineering Education, Universitas Pendidikan Indonesia, Bandung. The learning media program can be directly installed and accessed on personal computers for learning purposes. The research was conducted in 2016 and started with concept exploration to find the necessary product model, followed by its development through many test steps and correction procedures. The last step was product validation through quasi-experiments on a number of students taking the corrosion class. The result is animation-based interactive media that demonstrates good criteria in terms of a media expert judgment value of 78.3%, students’ response of 83.0%, and a subject matter expert judgment value of 89.0%. Validity tests show that the media has a significant effect on the increase in the number of students who reach minimum standard competency.
