Abstract

The controlling planning of raw material needs in a company is very important to keep productivity on production activityand its influence on the material procurement cost. UD. Jaya Abadi Solution is one of the company that produces various fodder from the waste of animal feed manufacturing factory. The fluctuation often happens in raw material availability for production process especially “tumpi” raw materialwhich causes the production process is not optimal. The purpose of the research is to control “tumpi” raw material availability by using Economic Order Quantity (EOQ) method and Period Order Quantity (POQ) methodand to know the different cost between the company calculation and EOQ and POQ methods caculations. The methods used in this research are Economic Order Quantity (EOQ) method and Period Order Quantity (POQ) method, these methods are expected to be able to cope the fluctuation of the “tumpi” raw material availability. Based on the result of the research using Economic Order Quantity (EOQ) method and Period Order Quantity (POQ) method yielded is EOQ value of 220 tons with total cost of Rp. 113.165.509, while POQ value is 205 tons with the total cost of Rp. 113.285.546. The different cost produced is 19 % compared to the company total cost.

Summary

Menghitung Nilai Reorder Point

Data historis pemakaian bahan baku tumpi dapat dilihat pada Gambar 2. Teknik pengumpulan data yang digunakan dalam penelitian ini adalah sebagai berikut : 1. Data primer adalah data-data dalam penelitian yang diperoleh secara langsung dari lapangan oleh narasumber melalui observasi dan wawancara. Ada 2 metode dalam pengumpulan data primer yaitu observasi dan wawancara. Adapun dokumen yang diambil dari lokasi penelitian yaitu data pemakaian tumpi, data-data biaya pemesanan, biaya penyimpanan dan data lead time. Pengolahan data yang digunakan pada penelitian ini ada 2 yaitu pengendalian persediaan bahan baku menggunakan metode EOQ dan metode POQ serta perbandingan selisih antara hasil perhitungan perusahaan dengan hasil perhitungan menggunakan metode Economic Order Quantity (EOQ) dan metode Period Order Quantity (POQ). Biaya pemesanan untuk pengadaan bahan baku tumpi dapat dilihat pada tabel 1.
