Inventory management is one of serious problem faced by companies. PT Garuda Putra – Putri Jaya (PT GPPJ Pati) is company which produce snack, like coated peanuts, soybean snack, and pillus. With a purpose to support production’s fluency which is afected in consumer demand fulfillment’ fluency, then PT GPPJ Pati management try to assure the availability of roll pack material. But, the failure in inventory management causing overstock in inventory of roll pack material which showed in high value of Days of Inventory (DOI). Based from preliminary research for knowing factors that affected to higher value of DOI, was concluded that the higher value of DOI caused by determination of order quantity that only consider farecast of roll pack material’s need, quantity of safety stock, and outstanding inventory in warehouse without calcuation process and still using intuition and experience of worker. Based form preliminary research, this research try to compared inventory control policy used by company (current policy), and (r,Q) inventory model based form forecasting with uncertainty demand, yield, and lead time which developed by Mohammed Zied Babai [Baba06]. Study of policy comparison was done with implementation of spreadsheet simulation with two policy scenario. From this simulation and policy analysis, was concluded that scenario 2 is best inventory control policy because deliver smallest DOI value, i.e. 36.02 days, and lowest inventory cost, i.e. Rp 5,775,116.41
