Abstract:
Inventory is the part that plays an important role in a company. Inventories
can be raw materials, goods in process and finished goods. For most
manufacturing companies, inventory is the greatest form of investment. A
company must be able to determine an appropriate inventory to get the maximum
benefit. Error in determining a stock can be fatal to the company itself. Therefore,
it takes a good inventory system that can make the production process continues
to run smoothly and produce the maximum profit.
Inventory management by using the method of P (R, T) will provide
recommendations to the PT "X" in determining the period of booking and the
amount of raw materials (75 yarns denier and 135 yarns denier for fabric of PS-TD-
1321, 135 yarns denier and 150 yarns denier for fabric of BS-TD-2317, 135
yarns denier and 150 yarns denier for fabric of BD-TD-3515, and starch) to be
booked. In addition, the method of Known Price Increase and Special Sale Price
is required to utilize the phenomenon of price changes that often occur in the
price of yarn that can produce the maximum Cost Saving.
The results of this study is an inventory system which is recommended to
PT "X" in determining the interval order and quantity of goods which must be
ordered by using the method of P (R, T). Method P (R, T) yields T and R
Optimum value for individual items and joint orders that will generate a minimum
total cost. It also recommended a method to utilize the phenomenon of change in
the price of yarn by using the method of Known Price Increase and Special Sale
Price for PT "X" to determine the number of special orders if there is an increase /
discount rates at one, more than one, or all types of yarns.
