Abstract : Antiseptic is a chemical substance that destroys microorganisms or inhibits work to prevent an infection system. One example of an antiseptic is alcohol. Alcohol, a primary ingredient for hand sanitizers, is now experiencing shortages due to the pandemic in Indonesia. These requests are generally intended for the sterilization and sanitation needs of a company that operates as an alcohol distributor, PT. X has received a lot of requests for alcohol due to the Covid-19 pandemic. Modeling and simulation can be done using the Monte Carlo method to meet the above requirements. After seeing the number of product requests, the next step is to send the product until the customer well receives it. Delivery is unbeatable with existing demand. The problem was that the product delivery was unbeatable with the vehicle capacity. So the shipping costs are pretty high. Companies can use the Vehicle Routing Problem (VRP) method that arises. The solution to the VRP problem is obtained by the Saving Matrix method. From this research, the expected demand (expected value) of 163.2 drums of alcohol per day differs from the average demand of 159 drums of alcohol using a simulation for 30 days and distribution routes, giving a distance of 228. km or with a proportion of savings of 31.84%.
