Rancang Bangun Aplikasi Perencanaan Pengelolaan Kebutuhan Bahan Baku untuk Produksi Air Bersih pada PDAM Surya Sembada Kota Surabaya
Abstract: Perusahaan
Daerah Air Minum
(PDAM) Surya Sembada
Surabaya is a state company for providing
drinking water for
the residents of
Surabaya (Walikota :
2003). Until now,
PDAM had difficulty in
determining the optimum order
and inventory raw materials cost economically for production. Because the raw material planning is only
based on the actual usage of raw
materials used to produce water in the previous period. The problems
required application management
planning needs of
raw material in
PDAM which can help
in planning raw
material requirements . This
application applies the methods
Forecasting Triple Exponential Smoothing
Winter determining the
average demand for raw materials with the data pattern
of seasonal and
tend to trend ,
Re-Order Point (ROP)
determining time of
booking returned after the
inventory reaches a certain amount ,
and Economic Order
Quantity (EOQ) determining the
optimum number of
orders resulting in an
economical total cost of inventory
on problems of supply to demand
is not permanent and seasonal
pattern. From the results of trials, the
application is successfully helping and generate value planning needs quickly and
accurately. It can be seen
from the response
time calculation raw
material planning with
forecasting methods, ROP and EOQ less than 15 minutes .
