The scheduling problem faced by the paintshop at motorcycle manufacturing industry, begins with how to complete the scheduling by minimizing setup time. Setup time is caused by the change of color in the production process paintshop. When a color change occurs in the paintshop production process, equipment must be cleaned before use for the next color. Therefore the scheduling generated by the paintshop at motorcycle manufacturing industry should be able to minimize the setup time caused by the color change. <br /> <br /> <br /> <br /> <br /> In addition to the minimization of setup time, delivery part to assembling line become one of the performance that must be fulfilled by paintshop section. The delivery paintshop section must be in accordance with the due date, if the delivery does not match the due date will have an impact on the line stop assembling. One study that considered the above problem is batch scheduling problem. The basic idea of this scheduling is to minimize total actual flow time on the shopfloor production. <br /> <br /> <br /> <br /> <br /> The method used in this research is the squential method. The first method is to sort the part that will be produced by the paintshop section by minimizing setup time using TSP algorithm. The second method is to schedule the results of the first method with a batch scheduling algorithm to minimize the actual total flowtime. <br /> <br /> <br /> <br /> <br /> From the result of model development, it is found that the total value of actual flowtime part in production floor is better than current model. From the scheduling results show that the results of the development of the scheduling model does not need to start production at t = 0. It can be used by the production department for more productive activities such as maintenance and GKM . Or by other means the production can obtain a greater amount of capacity than the slack time from the development of the scheduling model. In addition to the slack time, the development of the scheduling model also produces the minimum number of batches produced by the paintshop section with a total actual flowtime value of at least 50 units per batch
