Abstract :
Inventory control can be described as an activity to determine the level and
quantity required of raw material supplies. The supply of spare parts is very
dependent on the number of requests in each period and in general the demand for
an item is not always fixed. In the aircraft maintenance process, aircraft spare parts
are divided into 3 types, namely consumable, rotable and repairable. Based on the
previous explanation, this study will classify spare parts using the ABC method,
besides that inventory control will also be carried out using periodic review
analysis for consumable material types in order to obtain a more efficient inventory
cost.
Based on the results of the analysis using the ABC method for classifying
spare parts, the results obtained for class A spare parts are 6% with a total cost of
IDR 33,181,475,535. For class B spare parts, 49 items or 49% were obtained with
a total cost of IDR 4,473,956,515. for class C spare parts, 43 items were obtained
with a total cost of IDR 34,425,689.41. From the results of the analysis between the
min max method and the P model periodic review method, the periodic review
method produces a total inventory cost that is smaller than the Min max method.
