Abstract

Raw materials are the main factor in the company to support the smooth production process, both in large companies and small companies. The problem of determining the amount of demand is an important issue in the company, because inventory has a direct effect on company profits. Mistakes in determining the amount of investment (embedded capital) in inventory will determine the company's profit. The purpose of this study is to find out the number of economical order sizes, reduce storage costs, and know when to make an order. This research is focused on the raw material of button mushrooms produced by PT. XYZ.To predict the number of productions that must be produced in the upcoming period using the moving average and single exponential smoothing method, the data in the previous period. The moving average method uses a moving average of 2,3,4,5 and 6. While a single exponential smoothing α = 0.1 - 0.9. The forecasting method used is single exponential smoothing with α = 0.8 resulting in a small MAD of 5,381. The result of controlling raw material inventory, the smallest total annual inventory cost is chosen. From here the EOQ model of raw material supply control system is a good raw material inventory control system because it has a total inventory cost of Rp. 8,809,552.29 smaller with a frequency of ordering 9 times when compared to the previous inventory control system of Rp. 12,847,932.69 used by the company.

Abstract

Each company has different ways to manage raw material inventory. Starting from the number of units of raw materials, time of use, as well as the amount of costs to purchase raw materials. The amount of raw material inventory that is minimal or too big is feared will be an obstacle of a company's productivity, so it needs a good raw material management pattern for the company. Policies in inventory management need to be formulated appropriately so as to achieve the objectives expected by the company. There are several methods to control inventory levels, including the Economic Order Quantity (EOQ) model. The EOQ method is used to determine the optimal amount of goods in one period by minimizing total inventory cost. The inventory cost consists of setup cost and holding cost. Some of the advantages of implementing EOQ policies in inventory management are that investments embedded in inventories can be kept to a minimum and the number of raw material orders adjusted for consumption needs. UD. Plastics is one of the middle-level industries that manage plastic waste located in Tejowangi Village Purwosari District that develops local resource potentials. Re-Order Point, according to EOQ method is 7,971 kg, whereas according to UD policy. Plastic Purwosari no return order. The frequency of optimum raw material feeding according to EOQ method is 4 times in one month, while policy according to UD. Purwosari +-plastic is 15 times in 1 month. Total inventory cost is optimal for 1 year according to EOQ method of Rp. 568,419.41, whereas according to UD policy. Plastic Purwosari Rp. 770.631,22. So there is a difference of Rp. 202.211,81. Companies need to re-examine the methods of control applied so far, because based on the results of processing by methods used by researchers, Total inventory cost can still be minimized. By using EOQ method in raw material procurement policy, the company will get a minimum quantity of raw material purchasing compared to the previous company policy.

Abstract

The Material Requirement Planning (MRP) method is used to control the supply of raw materials in a company. A company to implement policies in raw material planning must have the right calculation so that there are no advantages and disadvantages in the supply of raw materials. This study aims to determine whether the application of the Material Requirement Planning (MRP) method in the "Duta Collection" business unit in planning the supply of raw materials can run effectively and efficiently. Material requirements planning using MRP method in this paper uses the lot sizing method, where the lot sizing methods used are Lot-for-Lot, and Economic Order Quantity (EOQ), as well as using the Exponential smoothing and least squares forecasting formula as a reference for know the amount of raw material needs in the future. From the calculation of the cost of raw materials in 2016 the total cost of raw material inventories incurred by the Duta Collection business unit was Rp12,797,247,650. Whereas by using the MRP method the total cost incurred was the Lot-for-lot Method of Rp 35,904,531,000 and the Economic Order Quantity (EOQ) Method of Rp 5,886,092,567. From the two MRP methods above, it can be seen that the Economic Order Quantity (EOQ) method has the lowest total inventory cost of Rp 5,886,092,567, - meaning the company can minimize inventory costs by 2.2% of the costs incurred. So as such it is proven that one of these MRP methods can play a role in efficient cost of raw material inventory in the Duta Collection business Unit.
