ABSTRACTHydrometric measurement divided runoff into several components such as surface runoff, interflow, and baseflow. The current research carried out by hydrometric and hydrochemistry measurements to address obtain information about the flow contributors in watershed. End member mixing analysis (EMMA) used to define source area in watershed. This method require hydrochemistry data on event based. The stream chemistry was projected on to a subspace mixing (triangular space) and well bounded by third source area. To test the validity of EMMA model for the catchment studied, linear regression between predicted and measured of each solute concentration of stream water were performed. The research was conducted at Cakardipa micro watershed, Cisukabirus sub watershed, Upper Ciliwung watershed. Result of the research showed that source area of Cakardipa watershed predicted by end member mixing analysis (EMMA) using Ca and SO4 tracer were groundwater, soil water, and rain water about 47,3%, 28 %, and 24,7% respectively.
