Inventory control is one of the important things of working capital in a company. Economic Order Quantity (EOQ) could be decided from the safety stock, maximum inventory, and reorder point in a company. The aim of the research was to know the number of stock and inventory cost savings. The research used EOQ method on controlling the packaging cup 240 ml and carton box to know the amount of safety stock, maximum inventory, and reorder point in PT. XYZ. The result showed that the sum of buying the material based on EOQ method in the 2015, 2016 and 2017.In the 2015 the amount f packaging cup 240ml were 1.492.031 cups, the amount f carton box were 25.164 cartons, in the 2016 the sum of packaging cup 240 ml were 1.492.084 cups, the sum of cartoon box were 24.697 cartons, while in the 2017 the sum of packaging cup were 240 cups. Using the EOQ method can be known that inventory cost savings as the result of the decreasing of the order. Safety stock were around 447.406 for a 240ml cups and 9.319 for cartons box. Maximum inventory based on EOQ method were around 992.445 for 240 ml cups and 20.549 for cartons. Reorder point based on EOQ method were around 860.066 for a 240ml cups and 17.918 for cartons.

The Madurese consumes corn as the primary source of carbohydrates. However, currently, they are experiencing a shift in consumption from corn to rice. It is caused by the availability of abundant rice. Moreover, another reason is the process of processing corn requires a relatively long time. The purpose of this research is to develop instant Madura corn rice. The method used in this research is the Quality Function Deployment (QFD) method. Based on the House of Quality matrix obtained 16 attributes of consumer needs both in terms of products and packaging. Highest Attributes of the needs of consumers are attributes without preservatives for the product aspect and presenting attributes for the packaging aspect. There are 17 attributes of technical requirements needed to meet the attributes of consumer needs. Highest priority The technical requirements are the corn type attribute for the product side and the font-size attribute for the packaging aspect. The results of product comparisons with competitors, Madura corn rice products have advantages in the yellow color attribute. Furthermore, It needs to be improved attributes about the texture a little soft.
An industry's supply chain system must be intensely improved to improve the company's performance. Factors that influence a performance are reliability, responsiveness, agility or flexibility, cost and assets. The performance of milk fish supply chain at UD TBS has not yet been measured by the performance of each distributor, so it is not yet known how effective the performance of the supply chain and the factors that can affect its performance. The purpose of this study was to determine the factors that influence the performance of milk fish supply chains and DMU values by the DEA method. The results showed that the most influential factor was cash-to-cash cycle time (the time needed by the distributor to the company in ordering milkfish. The effectiveness value of 20 distributors was obtained 85% effective (green) and 10% ineffective (amber) and 5% ineffective (red).
