One of the sectors to strengthen vocational education is conducting graduate searches. The aim is to map or find out the activities of alumni after graduating from school. The extent to which the competency of alumni obtained from the school can be absorbed and needed by industry. Several systems are in place that allow for completion of tracing. However, not all of these systems meet the school's desired needs. So it is necessary to design the system by adjusting the needs of the school. In the early stages of the research conducted a series of needs analysis to determine system specifications. One of them is object-oriented programming analysis design using UML modeling by applying four UML diagrams, namely class diagrams, activity diagrams, use case diagrams, and sequence diagrams.
