Abstract
The problem of improper process management of fresh fruit distribution centers results in the quality of fresh fruits decreasing. Therefore, this research aims to develop a discrete-event simulation using the FlexSim program to apply in the fresh lychee distribution center used as a case study and to improve the process of the fresh lychee distribution center used as a case study to be appropriate and consistent with cold chain management. The sample group is 2 operators of the fresh lychee distribution center used as a case study who were selected by purposive selection. The research instruments consist of an interview form and a process analysis form of the fresh lychee distribution center used as a case study. Data were collected by interviewing and site observation about the process of the fresh lychee distribution center used as a case study. The imported data is evaluated using the Expert Fit program, simulation is carried out using the FlexSim program, and the simulation validity of the model is checked using t-tests with ready-made computer programs. The results of the research found that the simulation model of the fresh lychee distribution center used as a case study that was created can be used to represent actual operations. The original work process should be improved by controlling the temperature appropriately and reducing the operation time to the shortest possible by switching and adjusting the work steps that can be done. The results from the simulation found that the improvement of the working process of the fresh lychee distribution center used as a case study can reduce the total operation time by 5,926.11 seconds or 63.94 percent and can also reduce wages.
