The contribution of the transportation and warehousing sector in Indonesia in 2020 decreased to rank eight at 3.81% compared to 2019 data at rank seven at 4.41%, according to data from the Central Bureau of Statistics Indonesia (BPS). The decline in the transportation and warehousing business sector to the GDP contribution has resulted in oil and gas companies implementing a strategic advantage with cost leadership to achieve a strategic fit for efficient supply chain lubricants. The existence of service time limits in the warehouse for shipping and receiving lubricant products is essential in determining an efficient route. The addition of depot points as a solution to meet the demand for lubricants to the service level. The proposed depot point is obtained through K-Means Clustering and optimal route with limited truck capacity and service time in the warehouse using the CVRPTW (Capacitated Vehicle Routing Problem with Time Windows) method. The data is used to realize shipments of lubricant products in 2019-2021 in state-owned oil and gas companies in Indonesia. The realization data for 2019 describes the demand for pre-covid 19 lubricants. The realization data for 2020 is the demand for lubricants during covid 19, and the realization data for 2021 describes the demand for lubricants post-covid-19. The results obtained two proposed hub points at coordinates -6.59395726,107.47077792 and -7.388939,111.76971405. Furthermore, the increase in truck utility is 72%, and the total cost after adding a depot is 10% lower than the existing condition.
