- The process of scheduling a lecture at a university is a process that has an important role. With a system that can perform scheduling by shortening the process and the absence of conflicting schedules, lecture activities will run in an orderly manner. This research will discuss about the process of scheduling lecture at Al Azhar University of Indonesia (UAI) by using genetic algorithm. Analysis of system requirements is done in accordance with business process scheduling lectures at UAI. In this genetic algorithm there is a hard constrain and soft constrain that can be determined according to need, such as a lecture schedule should not be any that incline with other lecture schedules. The system can record schedules that can be met and also can't be met lecturers, so that when in the process of scheduling, the system can find another replacement time. There is a change in the business process of lecture scheduling in UAI, and also has an impact on the development of lecture scheduling information system. There is an input and output json file that is used for communication between existing lecture scheduling information systems with genetic algorithm scheduling system.
