		abstract={PT. Gramedia is a company engaged in printing newspapers, magazines, books
and comics. Problems that occur in the warehouse of PT. Gramedia is a frequent
occurrence of shortages and excess material of paper material bookpaper. This
happens because ordering paper bookpaper to suppliers is only based on material
requests from the user without looking at the inventory status in the warehouse.
Research Methods Planning the needs of raw materials for paper material begins
with forecasting for needs in the coming year. Forecasting used is the Moving
Average forecasting method (2 months, 3 months, 4 months). Linear Trend
Forecasting. Exponential Smoothing (α0.7, α0.8 and α0,9) Forecasting. From the
results of forecasting calculations that have been tested validation using tracking
signal. Linear trends have the smallest error value and are within the control
limit. By knowing inventory data and the cost component data of paper bookpaper
material, then compared several methods namely Economic Order Quantity,
Order Quantity Period, Least Unit Cost, and Least Total Cost. From the
comparison, the results of the Least Total Cost method have the smallest total cost
of Rp. 370,890. Where the order is made in each period or does not apply the
merger period.

PT. Gramedia merupakan perusahaan yang bergerak di bidang percetakan koran,
majalah, buku dan komik. Permasalahan yang terjadi di gudang PT. Gramedia
adalah sering terjadi kekurangan dan kelebihan bahan baku material kertas
bookpaper. Hal ini terjadi karena pemesanan kertas bookpaper kepada supplier
hanya berdasarkan request material dari user tanpa melihat status persediaan di
dalam gudang. Metode Penelitian perencanaan kebutuhan bahan baku material
kertas bookpaper diawali dengan peramalan untuk kebutuhan di tahun yang akan
datang. Peramalan yang digunakan yakni metode Peramalan Rata-Rata Bergerak
(Moving Average) (2 bulan, 3 bulan, 4 bulan). Peramalan Trend Linier. Peramalan
Penghalusan Eksponensial (Exponential Smoothing) (α0,7, α0,8 dan α0,9). Dari
hasil perhitungan peramalan yang telah diuji validasi menggunakan tracking
signal. Trend linier memiliki nilai error terkecil dan berada dalam batas kendali.
Dengan mengetahui data persediaan dan data komponen biaya material kertas
bookpaper maka dibandingkan beberapa metode yakni Economic Order Quantity,
Periode Order Quantity, Least Unit Cost, dan Least Total Cost. Dari
perbandingan didapat hasil metode Least Total Cost memiliki total biaya yang
terkecil sebesar Rp 370,890 Dimana pemesanan dilakukan pada setiap periode
atau tidak berlaku penggabungan periode.
