The method used in this research is waterfall using 4 stages, namely analysis, design, coding, and testing. The selection of the waterfall method is because the stages in the waterfall are systematic in sequence. This certainly makes it easy for developers to create information systems. The results of this development resulted in an application entitled International Conference State University of Malang "ICON-UM". Based on the results of black-box testing, it is interpreted that all functions developed run optimally. This system can be a recommendation for international conference organizers.
