This research the purpose to set criteria for decision making in the quantity of inventory stock. To
reduce the amount of inventory of the storage plant a case study of plastic molding, This research by
collecting data from a given quantity of finished product inventory. Found that the problem isthe volumes of
finished inventories are much more than necessary. Due to the forecast of a factory method with dislocation.
Then define the analysis method using ABC Analysis with all finished product and how to control the
inventory of each group (Class) group A (Class A) and Group B (Class B), Use the determination level of the
oµª´Ã¨ª·¥µ«µ­¦r¸
$GYDQFHG6FLHQFH
amount of finished product inventory in stock and shortage goods. Using the 80/20 theory as a basis for the
decision and used as Replenishment system (replenishment), Group C (Class C) change the method
manufacturing to store (make to stock: MTS), Is based on a purchase order (make to order: MTO), After
updating Forecasts in Group A and B found that. Can reduce the amount of inventory in stock 33.86 percent.
