The inventory plays an important role for company business, because most of the <br /> <br /> working capital will be absorbed in the inventory value, which will burden the <br /> <br /> financial cash flow of the company. The inventory has to be managed at the <br /> <br /> optimum level, to make balance between the service level and the inventory level. <br /> <br /> This research gives an alternative method for calculation of safety stock that <br /> <br /> correlates the value factors and the risk factors of starting materials. <br /> <br /> The retrospective data at 2017 is collected for 550 items of raw materials and 725 <br /> <br /> items of packaging materials. The value factor is calculated using ABC analysis, <br /> <br /> while the risk factor is calculated using some parameters (supplier audit, <br /> <br /> percentage of rejection and complaint, delay of delivery, and function of starting <br /> <br /> materials). Then, the value and the risk factors are combined for determination of <br /> <br /> the value-risk score (VR score) used for safety stock calculation. The comparison <br /> <br /> study of amount and value of safety stock is compared with the current method in <br /> <br /> company A and the Z score method. <br /> <br /> The result of the research showed that the VR score method can reduce the <br /> <br /> inventory value of raw materials by 34% compared with the current method in <br /> <br /> company A. The VR score method for the packaging materials recommends to <br /> <br /> raise 50% of safety stock compare with the current method, but still lower than <br /> <br /> safety stock calculation using the Z score method. This is because in company A, <br /> <br /> the risk score of packaging materials is higher than raw materials, so packaging <br /> <br /> materials require higher safety stock level. <br />
