Abstract

ABSTRAK Koperasi Industri Batur Jaya merupakan Industri Kecil Menengah yang bergerak pada bidang pengecoran logam dan permesinan. Koperasi Batur Jaya menggunakan sistem Make To Order (MTO), perusahaan hanya mengira-ngira dalam melakukan jumlah pembelian bahan baku. Dari hasil observasi didapatkan penemuan masalah manajemen rantai pasok kurang baik sehingga terjadi overstok atau kelebihan bahan baku. Penelitian ini bertujuan untuk mengetahui jumlah permintaan dimasa yang akan datang setiap bulan dengan peramalan, berapa jumlah pemesanan dan jadwal pemesanan bahan baku dengan metode Material Requirement Planning (MRP). Metode peramalan yang digunakan dalam penelitian ini adalah metode Moving Average, Single Exponential Smoothing dan Weighted Moving Averages. Teknik Lot Sizing yang digunakan dalam sistem Material Requirement Planning yaitu Lot for Lot (LFL), Period Order Quantity (POQ) dan Part Period Balancing (PPB). Dari metode yang diusulkan didapatkan hasil total biaya terkecil yaitu dengan menggunakan metode Period Order Quantity (POQ) sebesar Rp.25.479.968 . sehingga dari hasil penelitian menunjukkan bahwa penerapan metode Material Requirement Planning (MRP) dapat meminimalkan biaya kebutuhan sebesar Rp. 8.135.068 atau 24,2% dari perhitungan dengan metode Perusahaan. Kata Kunci : Pengendalian Persediaan, Material Requirement Planning, LFL, POQ, PPB. ABSTRACT The Batur Jaya Industrial Cooperative is a Small to Medium Industry engaged in metal casting and machining. The Batur Jaya Cooperative uses a Make To Order (MTO) system, the company only estimates the amount of raw material purchases. From the observation results, it was found that supply chain management problems were not good enough to cause overstock or excess raw materials. This study aims to determine the number of requests in the future every month with forecasting, the number of orders and the schedule for ordering raw materials using the Material Requirement Planning (MRP) method. The forecasting method used in this study is the Moving Average, Single Exponential Smoothing and Weighted Moving Averages methods. The Lot Sizing techniques used in the Material Requirement Planning system are Lot for Lot (LFL), Period Order Quantity (POQ) and Part Period Balancing (PPB). From the proposed method, the smallest total cost is obtained by using the Period Order Quantity (POQ) method of IDR 25,479,968. So, the research results show that the application of the Material Requirement Planning (MRP) method can minimize the requirement cost of IDR 8,135,068 or 24.2% of calculations using the Company method. Keywords: Inventory Control, Material Requirement Planning, LFL, POQ, PPB.
