RANCANG BANGUN MODEL PERSEDIAAN DAN PEMILIHAN PEMASOK BAHAN BAKU KELAPA PARUT KERING DI PT. X
ABSTRACT: PT. X
is an integrated
agro-industry coconut company.
The main products
produced are desicated coconut
from coconut grain
with a shelf
life of 7
days as raw
materials. The company currently constrained
in 30-40% expired
stock at the
warehouse and insufficient
capacity of the warehouse. Another
problem is the
supply of raw
materials (desicated coconut)
from suppliers around 20-35% did
not comply with the specifications of diameter ≥ 10 cm. Seeing these conditions
required the model
design of inventory
and supplier selection
with a balance
of shelf life
and storage capacity as well as alternative suppliers that capable to
provide raw materials (desicated coconut) with a diameter ≥ 10 cm continually.
The method used in the design of this model is the development of
methods Economic Order
Quantity (EOQP) and
lagrange multiplier used
for the economic lot
size ordering and
fulfillment warehouse storage
capacity as well
as methods Analitycal Hierarchy
Process (AHP) for
the selection of
alternative suppliers that
meet the specifications of raw
materials and economical ordering quantity lots. The results of the design of this
model produced economically ordering lot size 300.000 coconuts with total
inventory cost Rp. 55,5 million and
is the District
1 alternative suppliers.
In accordance with the
results of analysis and expert opinion that the study
design was verified and valid models.
