Abstract

ABSTRAK CV Satya Furniture merupakan perusahaan yang bergerak di bidang industri Furniture, CV Satya Furniture memproduksi berbagai macam produk seperti rak, meja, etalase dan beberapa aksesoris pendukung untuk kebutuhan Indomaret. CV Satya Furniture masih memiliki kelemahan dalam proses pengadaan bahan baku dikarenakan belum ada divisi gudang yang mengatur input dan output dari bahan baku yang digunakan. Tujuan penelitian ini untuk menganalisis pengendalian persediaan bahan baku dan menentukan metode yang menghasilkan total biaya persediaan terendah. Penelitian ini bertujuan untuk menganalisis metode peramalan dan teknik lot sizing dalam pengendalian persediaan bahan baku produk Meja Pos Kasir pada CV Satya Furniture. Peramalan dilakukan menggunakan metode Double Exponential Smoothing dan Winter’s Method berdasarkan data historis selama satu tahun. Hasil analisis menunjukkan bahwa metode Winter’s Method dengan parameter α=0,5, γ=0,5, dan δ=0,5 memberikan nilai Mean Absolute Deviation (MAD) sebesar 4,8479, jauh lebih rendah dibandingkan Double Exponential Smoothing (MAD sebesar 22,447). Hal ini membuktikan bahwa Winter’s Method lebih akurat karena mampu mempertimbangkan komponen musiman, tren, dan tingkat. Pengendalian persediaan dilakukan menggunakan metode Material Requirement Planning (MRP) dengan teknik lot sizing Economic Order Quantity (EOQ) dan Lot for lot (LFL). Hasil perhitungan menunjukkan bahwa total biaya persediaan menggunakan EOQ sebesar Rp139.232.316,00, lebih tinggi dibandingkan LFL sebesar Rp72.732.000,00. Penggunaan LFL mampu menurunkan total biaya persediaan sebesar 47,7% dibandingkan EOQ. Teknik LFL menghasilkan biaya lebih efisien karena mengurangi total biaya persediaan karena tidak adanya biaya penyimpanan yang dikeluarkan untuk menyimpan bahan baku. Kata Kunci: Material Requirement Planning, Economic Order Quantity, Lot for Lot, Persediaan Bahan Baku ABSTRACT CV Satya Furniture is a company operating in the furniture industry that produces various products such as shelves, tables, display cases, and supporting accessories for Indomaret's needs. However, CV Satya Furniture faces challenges in the raw material procurement process due to the absence of a dedicated warehouse division to manage the input and output of raw materials. This study aims to analyze raw material inventory control and identify the method that minimizes total inventory costs. This research evaluates forecasting methods and Lot sizing techniques for managing raw material inventory, specifically for the Cashier Desk product at CV Satya Furniture. Forecasting uses the Double Exponential Smoothing and Winter's Method based on historical data collected over one year. The analysis results indicate that Winter's Method, with parameters α = 0.5, γ = 0.5, and δ = 0.5, yields a Mean Absolute Deviation (MAD) value of 4.8479, significantly lower than that of Double Exponential Smoothing, which has a MAD of 22.447. This result demonstrates that the Winter's Method is more precise as it can consider seasonal components, trends, and levels. Inventory control is conducted using the Material Requirement Planning (MRP) method, incorporating the Economic Order Quantity (EOQ) and Lot for Lot (LFL) lot sizing techniques. The calculation results indicate that the total inventory cost using EOQ is Rp139,232,316.00, which is higher than the LFL of Rp72,732,000.00. Using LFL can lead to a 47.7% reduction in total inventory costs compared to EOQ. The LFL technique is more cost-efficient as it reduces the overall inventory cost by eliminating the need for storage costs for raw materials. Keywords: Material Requirement Planning, Economic Order Quantity, Lot for Lot, Raw Material Inventory
