Polyesteris observed since it is imported fabric rawmaterial which mostly used in the company.The polyester usage predicted by regressionis continuously increases per month. Theforecasting result can be accepted becausethe tracking signal value is not more than ± 4.Whereas, EOQ method is more suitable to beused by the company since the inventory costis lower than the cost applying JIT concept. Itis possible to save 13% or 9,512,693.3 IDR.Moreover, by applying EOQ method, it alsodetermines the reorder point (ROP) andsafety stock inventory to guarantee thesmoothness of production activities.
