| dc.description.abstract | In the distribution of Fuel (BBM) for Pertamina Shop (PERTASHOP), Teluk Kabung Fuel Terminal (TBBM) utilizes a hub facility. This hub was built with the primary purpose of reducing the distance between TBBM Teluk Kabung and PERTASHOP. Additionally, the hub serves as a breaking point, receiving a large quantity of BBM and then redistributing it into smaller amounts according to PERTASHOP's demand. Currently, TBBM Teluk Kabung plans to increase the number of existing hubs. Therefore, an analysis is required to determine the optimal number of hubs that can optimize the reduction of distance, travel time, waiting time, and total Tanker Truck (MT) capacity. The analysis of the optimal number of hubs employs the Location Routing Problem (LRP) model, which combines the Location Allocation Problem (LAP) and the Vehicle Routing Problem (VRP) with the development of alternative scenarios. Alternative scenarios are the possibilities of the number of hubs that will yield the best results for the LRP model. The number of alternative scenarios is obtained from the LAP results using the Set Covering Problem (SCP) and further developed using the P-Median model. In the VRP calculations, four variants are considered: Multi Trip VRP (MTVRP), VRP with Time Window (VRPTW), Heterogeneous Fleet VRP (HFVRP), and VRP with road classification. The research findings indicate that the fifth alternative scenario with 6 hubs has a total distance of 15,602.47 km, a total travel time of 364.09 hours, and the smallest average waiting time of 10.72 hours. On the other hand, the third alternative scenario with 4 hubs has the smallest total MT capacity, which is 654 liters. | en_US |
