Abstract

The aim of this research is to evaluate raw material inventory control at the UMKM Asy-syifa Bakery and determine the most economical order quantities and costs. The data used is a report on the purchase and use of wheat flour raw materials at the UMKM Asy-syifa Bakery in 2023. The data analysis technique compares raw material inventory costs between the Economic Order Quantity Method and the Just In Time Method. The standard requirement for wheat flour is 6050 kilograms, sugar is 651 kilograms, eggs are 480 kilograms, margarine is 120 cartons, and milk is 360 liters. Based on the calculations that have been carried out, the cost of raw material inventory using the Order Quantity Economic method is 2,746,327 rupiah and the cost using the Just In Time method is 3,446 231 rupiah, with a difference in 2023 of 699,904 rupiah, which is equivalent to around 20.3% of the total cost inventory. The results show that the EOQ method is more efficient than Just In Time.

Abstract

This study aims to evaluate the inventory control system of PT Citra Adilancar which can minimize inventory costs by comparing the company's total inventory cost system. So a research was carried out using the Just In Time method to reduce excess raw materials and the kanban method to expedite the Just In Time course so that there is no excess raw material anymore. The objects of this research were plate raw materials, holo iron, angle iron, resin, talc, fiber, catalyst and putty with several variables. The dependent variable is optimal raw material inventory and minimum total inventory cost, while the independent variables are raw material inventory data, raw material ordering costs, holding costs, demand data, and ordering data. The method used in this study is the Just In Time and Kanban method, which can reduce excess raw materials and produce on time. With the storage method the company has a total inventory cost of Rp. 213,130,000. The inventory system with the Just In Time method has a total cost of Rp. 183,967,500. From the results of these calculations, the minimum inventory cost is obtained using the Just In Time method. And make related proposals to change the inventory control system. To create an accurate Just In Time system, a kanban card is then designed.
