Pengelolaan Supply Produk Waferstick dengan Mempertimbangkan Kapasitas Produksi dan Persediaan Barang Jadi di PT. Tiga Pilar Sejahtera Food,Tbk
Abstract: In general, planning
supply use the information from combination varying capacity and inventory to
plan the aggregate rates of production by time period for groups of product.
This research objective is PT. Tiga Pilar Sejahtera’s (TPS) that produces wafersticks.
In the company sometimes occured the wafersticks product can be not fulfilled.
This is happened because waferstick inventory unstable. This causes problems
that PT. Tiga Pilar Sejahtera (TPS) was less capable to fulfill the market’s
demands. To solve this PT TPS should be managing the working hours, workforces,
production capacity and finished goods inventory, they are called aggregate
planning. This research are determine safety stocks, planning supply and
material inventory planning.Managing supply of waferstick product is started by
forecast the demand. The forecast result is used to estimate safety stock of
waferstick. Then the forecasting result and safety stock become of input
Integer linier programming model to determine aggregate planning. The aggregate
planning is used to find optomal lot size of waferstick raw material. Then lot
sizing become input Planned Order Receipt in the Material Planning Requirements
(MRP). Forecast method used to forecast the demand is decomposition, this
method is he best method find estimation demand because it have more less MAD
than the other. The determination of the safety stock is actually more accurate
with the 90% by Romy & Yuli waferstick safety inventory is 1106 cartons and
2364 cartons for Pio. From aggregate planning there is back order in 13 th is
11 cartons. The planning cost for Romy & Yuli waferstick Rp 625.670.902,33
and Cost for Pio waferstick Rp 1.462.296.180,00. Waferstick material planning
by optimal lot size between 695 kilograms up to 8487 kilograms by waferstick
materials cost is Rp 6.315.520,00.
