    Abstract: A problem to allocate n number of employees in a directorate/division into a given set of organizational shifts is the Employee Timetabling Problem (ETP). The main purpose of employee timetabling in this research is the allocation of n employees who should be assigned each day so that no idle workers. To solve the ETP and the main purpose of this research in create mathematical modeling represented 0-1 Integer Linear Programming (ILP) Model. The ETP is solved by considering two criteria as the constraints, there are the organizational rules and employee’s requirement with the objective function that is to minimize the number of employees to minimize labor costs. About 0-1 ILP Model obtained from process organization data input and employee data input. Employee data input can be done manually or automatically from database with the help of Software Excel. The 0-1 ILP Model solved by framework SCIP optimization suite which then implemented into application of ETP simulation that are developed by Software Microsoft Visual Studio.
