Abstract

ABSTRAK PT Gramasurya berbisnis di bidang percetakan dan penerbitan di Yogyakarta. Produk unggulannya yaitu majalah suara muhammadiyah (SM) yang diproduksi berdasarkan permintaan pelanggan. Setiap bulan permintaan tidak tetap, namun biasanya berkisar diantara 36.000 oplag. Permintaan yang fluktuatif dari Maret 2021 sampai Februari 2024 menjadi masalah karena dalam pemesanan bahan baku perusahaan belum menerapkan metode khusus, dan hanya menggunakan metode perkiraan berdasarkan jumlah stok di gudang. Kurang efektifnya perencanaan menyebabkan overstock bahan baku kertas HVS 58 gram sebanyak 1001 rim. Tujuan penelitian yaitu mengetahui perencanaan, pengendalian persediaan, serta metode pemesanan agar dapat memberikan hasil optimal dengan biaya minimal. Metode yang cocok digunakan yaitu Material Requirement Planning (MRP) dengan Lot For Lot (LFL), Economic Order Quantity (EOQ), dan Period Order Quantity (POQ). Penggunaan Lot For Lot (LFL), menghasilkan biaya minimal yaitu Rp 2.320.000 dibandingkan yang dijalankan perusahaan, sehingga dapat menghemat biaya persediaan sebesar Rp 1.948.127 dengan persentase 46%. Kata Kunci: Lot Sizing, Majalah, Material Requirement Planning, Persediaan ABSTRACT PT Gramasurya operates in the printing and publishing industry in Yogyakarta. The Suara Muhammadiyah (SM) magazine, its flagship product, is produced according to customer demand. The demand varies each month but generally falls within the range of 36,000 copies. The fluctuating demand from March 2021 to February 2024 poses a problem for the company because they have not implemented a special method for ordering raw materials. Instead, they rely on an estimated method based on the warehouse's stock amount. An excess of 1001 reams of 58-gram HVS paper raw materials is due to inadequate planning. The study aimed to identify efficient planning, inventory control, and ordering techniques to achieve optimal outcomes at minimal expenses. Material Requirement Planning (MRP) with Lot For Lot (LFL), Economic Order Quantity (EOQ), and Period Order Quantity (POQ) are recommended methods. Implementing Lot For Lot (LFL) reduces costs to IDR 2,320,000, resulting in savings of IDR 1,948,127, equivalent to 46% of inventory costs. Keywords: Lot Sizing, Magazine, Material Requirement Planning, Inventory
