PT. XYZ is a company engaged in the process of making eucalyptus oil. The company produces eucalyptus oil where the main raw material is eucalyptus leaves. This company has problems in controlling the supply of raw materials of eucalyptus leaves caused by the erratic demand of eucalyptus oil by consumers. The company experiences a state of excess inventory which results in high inventory costs and lack of inventory resulting in production that does not fulfill orders. Based on the above problems, inventory control is carried out using the continuous review system backorder and lost sales method. The purpose of this study is to control the inventory of eucalyptus leaves so as to minimize inventory costs. The continuous review system backorder and lost sales method will be compared with the company method and the best method is chosen with the minimum total cost. The results of the calculation obtained the minimum total inventory cost with the continuous review system backorder method of Rp.2,459,692,004, while the company's method of Rp2,595,684,800, so as to get a cost savings of Rp.135,992,796 with an efficiency of 5.2%. The number of raw material orders per message in November 2019 - October 2020 amounted to 1,812 tons, with a total cost of supplying raw materials amounting to Rp 2,544,762,825.   Keywords: Continuous, Control, Inventory.

Spreadsheet Software

Businesses that carry inventory as a means of responding to customer demand must decide when to place inventory orders and how much to order. A model for selecting an optimal order quantity and reorder point in the continuous review system is implemented in spreadsheet software. Historical data on period demand and lead time is processed by performing a statistical test to select a mixture distribution for lead time demand. This distribution is incorporated into an expected shortage calculation and cost model where shortages incur lost sales and/or goodwill costs. The lead time demand distribution selection is evaluated through experiments. In examples, employing an incorrect distribution leads to expenditures between one and eighteen percent higher than those experienced with the correct model. A mismatch of the backorder or lost sales model with the correct underlying assumptions leads to expenses between four and thirteen percent larger than necessary in an example problem.
