SIMULASI PENGARUH RISIKO SUPPLY CHAIN TERHADAP KETERLAMBATAN PENGADAAN MATERIAL BAJA TULANGAN DENGAN METODE MONTE CARLO
ABSTRACT: Work on the building
project requires a material that is more complex and involves many parties so
that the building project has a high complexity compared to other civilian
buildings. One of the complexity of such problems in the procurement of
materials. Some of the things that causes this problem is the existence of an
uncertainty in the supply of construction materials. Reinforcement steel is the
main ingredient in development , especially the construction of the building.
The need of reinforcing steel required at each work ranging from foundation
work , beams , plates and columns. Therefore, the availability of steel
reinforcement is a major priority so that there should be no delay in procurement.
Delays of this material may be caused by uncertainties in procurement activity.
Uncertainties in the procurement of materials sourced from four stages: stage
supply chain activities supply, control, process, and demand. The stages of the
supply chain to be a reference to analyze the possibility of delays in the
procurement of a material. Thus, this study aims to determine how much time
minimum and maximum time delay procurement of materials, the maximum possible
delay in work activities and work activities that are most likely and dominant
risk that affects the delay procurement of materials for steel material. The
major delays in the procurement of material obtained from the analysis of
probability and risk impact with monte carlo method and application assistance
crystal ball. In the procurement of steel material analysis showed that a
minimum delay of 2.20 days,17.05 days maximum, the maximum possible delay in
work activities 15.05 days, and delays in work activities that are most likely
9.24 days. Sources of risk that affect the delay is on the demand stage that
ordering additional material due to design changes, material delivery delays
due to financial problems, and ordering additional material due to changes of
function space.
