Abstract
Company X is a distribution company and has a function as Regional Distribution
Center (RDC) for the region of Jakarta. RDC supplies margarine to its five
distribution centers (DCs). Current Reorder Point (ROP) replenishment system
often makes RDC Jakarta running out of stock when the orders come from the
DCs. Distribution Requirements Planning (DRP) is considered as a method to
solve the company's problem. The objective of this research is to analyze
potential enhancement of the company logistics performance using DRP method
instead of ROP for period August - October 2006.
On DRP's calculation, the author divides 4 planning scenarios. DRP scenario 1
and 2 use practical method which ignores the relationship among DRP inputs
theoretically (forecasting, order quantity and safety stock is considered
independent one another). DRP scenario 3 and 4 use theoretic method which
considers the relationship every DRP inputs theoretically. Then, the four scenarios
will be simulated with real condition at the company for period August - October
2006. The result will be compared with ROP method for the same period.
Based on the DRP and ROP overall performance indicators comparison using
service level and cost / investment criteria for period August - October 2006, the
results are: For DCs level, DRP scenario 1 and 2 have the same performance with
ROP meanwhile DRP scenario 3 and 4 have the better overall performance (20 -
30%) than ROP. For RDC level, DRP scenario 1 and 2 have the better overall
performance (15 — 20 %) than ROP meanwhile DRP scenario 3 and 4 have much
better overall performance than ROP. Based on these realities, the conclusion is
DRP method has the better overall performance than ROP without sacrificing its
five DCs performance. / Perusahaan X adalah perusahaan distribusi produk margarin dan berrlingsi sebagai
Regional Distribution Center (RDC) wilayah Jakarta RDC memasok produk
margarin ke lima Distribution Center (DC). Sistem replenishment metode reorder
point (ROP) yang digunakan perusahaan saat ini sering membuat RDC Jakarta
kehabisan persediaan saat pesanan datang dari DC Untuk mengatasi masalah
tersebut, penulis memberikan usulan perbaikan performansi logistik perusahaan
dengan menggunakan metode Distribution Requirements Planning (DRP) Tujuan
penelitian adalah menganalisis potensi peningkatan performansi logistik
perusahaan dibeberapa area yang saat ini menggunakan metode ROP bila diganti
dengan menggunakan metode DRP.
Dalam perhitungan DRP, penulis membagi menjadi 4 skenario perencanaan DRP
skenario 1 dan 2 menggunakan metode praktis yang tidak memperhatikan
keterkaitan hubungan masukan DRP yang akan digunakan secara teoritis
(peramalan, order quantity dan safety stock dianggap independen satu dengan
yang lainnya). DRP skenario 3 dan 4 menggunakan metode teoritis yang
memperhatikan keterkaitan hubungan masukan DRP secara teoritis. Keempat
skenario DRP kemudian disimulasikan dengan kondisi aktual perusahaan periode
Agustus - Oktober 2006. Setelah itu dibandingkan hasil performansinya dengan
metode ROP untuk periode yang sama.
Berdasarkan hasil perbandingan indikator performansi metode ROP dengan DRP
menurut kriteria service level dan biaya / investasi secara keseluruhan untuk
periode Agustus - Oktober 2006, diperoleh hasil pada tingkat DC: Metode DRP
skenario 1 dan 2 memberikan hasil keseluruhan yang tidak lebih baik daripada
metode ROP namun DRP skenario 3 dan 4 memberikan hasil keseluruhan yang
lebih baik (20 - 30%). Sedangkan pada tingkat RDC, DRP skenario 1 dan 2
memberikan hasil keseluruhan yang lebih baik (15 - 20%) daripada metode ROP
namun DRP skenario 3 dan 4 memberikan hasil keseluruhan yang jauh lebih baik
(50%). Berdasarkan hal tersebut, maka peningkatan performansi perusahaan
(RDC Jakarta) yang menggunakan metode ROP dapat ditingkatkan melalui
penggunaan metode DRP tanpa mengorbankan performansi yang telah dicapai
oleh kelima DC sebelumnya.
