ABSTRACT
Stockout and overstock are the trigger factors for increased costs. Overstock will result in waste in the cost of saving, but if the inventory is small, there will be a potential loss of opportunity for profit if the actual demand is greater than the estimated inventory and trigger customer disappointment.
This research is applied research. For the planning of medicine and consumer goods inventory management, ABC analysis is carried out to find out the products that become classes A, B, and C. Results of 51 class A product analysis are predicted using the moving average method for the needs of January 2019 and calculated EOQ and ROP.
The results of the comparison of total company costs compared to the EOQ
model produce smaller results and save more costs.
Interviews were conducted with the head of finance and head of marketing regarding the current inventory control system, as well as brainstorming the causes of frequent stockouts using fishbone diagrams.
The main causes of frequency of frequent stockouts using fishbone diagrams are: (1) lack of communication and coordination between planners, marketing, and warehouses; (2) there are no sales plans; and (3) estimated stock requirements that are less than demand and vice versa (planning does not match reality).
Keywords: ABC analysis, inventory control, fishbone, EOQ, stockout.
