Abstract :
The Medali Mas weaving industry is one of the many weaving industries which has long been producing woven fabrics in various models and patterns. Problems faced by researchers regarding the supply of raw materials, due to the absence of controlling the amount of inventory of raw materials needed specifically, while the company is faced with demand uncertainty which is very influential on the procurement of raw material supplies. So the holding of research with forecasting methods to calculate the needs in one production period. The variable in this research is about controlling raw material inventory. The first is to collect raw material needs data. Perform forecasting with the Exponential Smoothing method ? = 0.15, and Moving Average N = 2. Next, the forecast results determine the smallest error value with the indicators MAD, MSE, and MAPE. After the chosen method will be used as a reference for forecasting in the next period. Then perform efficient safety stock and reorder point calculations for one production period. From the results of calculations on raw material yarn produces Maximum Inventory = 4287 kg; Safety Stock = 53 kg; Reorder Point = 128 kg while on the raw material paint Maximum Inventory = 304 kg; Safety Stock = 7 kg; Reorder Point = 12 kg. Kata Kunci : Forecasting, Stock, Reorder Point.Safety Stock.
