Abstract: A mathematical model is a description of a system that uses mathematical concepts and language. The process of developing a mathematical model called mathematical modeling. Mathematical models are used not only in the natural sciences and engineering disciplines but also in social sciences (such as economics, psychology, sociology and political science, medical and dentistry) used a mathematical model that is most widespread. A model may help to explain the system and to study the effects of different components and to make predictions about the behavior. Mathematical models can take many forms including but not limited to dynamical systems, statistical models, differential equations or game theory models. In general, the mathematical model can include logical models as far as logic is taken as a part of mathematics. This research design a mathematical model of the palatine rugae subras deuteromelayu with a mathematical model approach fingerprints. Rugae palatine is an organ that has the unique properties of each individual person, palatine rugae can be analyzed through the number, length, direction and shape. The uniqueness of every shape and pattern of the palatine rugae can be used as the basis for the identification of individuals.
