Abstract

In the competitive world of business, demand forecasting is a critical aspect of inventory management. Errors in estimating demand can result in various negative impacts, such as excess inventory that increases storage costs or stock shortages that can lead to lost sales opportunities. UD. Haili often faces challenges in managing inventory due to unpredictable fluctuations in demand. In some cases, demand for certain products experiences sudden spikes, while at other times demand drops sharply. This creates the risk of inventory imbalances, leading to increased operational costs and the potential loss of customers. The objective of this study is to apply the single exponential smoothing (SES) method in forecasting demand for goods so that the forecasting results can provide strategic recommendations for UD. Haili in managing inventory based on the forecasting results. The forecasting results using the developed forecasting application indicate that round shrimp paste has the smallest MAPE, using an alpha of 0.4 with 1.26%, square shrimp paste uses an alpha of 0.1 with 1.98%, and triangular shrimp paste uses an alpha of 0.1 with 4.53%.

Abstract: Fitri Keramik Shop sells various types of ceramics. In this research, the researcher created a system that can make it easier to predict demand for ceramics in the following month based on the categories in Fitri Keramik by explaining the correct method for forecasting, one of the methods that can be used is Double Exponential Smoothing (DES) which is a forecasting method using uses a number of new actual demand data to generate forecast values for future demand by finding the average value as a forecast for the future period. The results of predicting demand for ceramics using an alpha value of 0.3 and having the lowest error rate are May 2023, Terraso: 176; Mosaic : 169; Standard Ceramic Floor: 163; Squared : 117.            Keywords: Analysis, Double Exponential Smoothing, Predicting Demand.  Abstrak: Toko Fitri Keramik melakukan penjualan berbagai jenis keramik. Pada penelitian ini, peneliti membuat sistem yang dapat memudahkan dalam meramalkan permintaan keramik pada bulan berikutnya berdasarkan kategori yang ada pada Fitri Keramik dengan memaparkan metode yang tepat dalam peramalan, salah satu metode yang dapat digunakan yaitu Double Exponential Smoothing (DES) yang merupakan metode peramalan dengan menggunakan sejumlah data aktual permintaan yang baru untuk membangkitkan nilai ramalan untuk permintaan dimasa yang akan datang dengan mencari nilai rata-rata tersebut sebagai ramalan untuk periode yang akan datang. Hasilnya dari memprediksi permintaan keramik dengan menggunakan nilai alpa 0,3 dan memiliki nilai tingkat error terendah yaitu Mei 2023, Teraso : 176; Mozaik : 169; Keramik Lantai Standart: 163; Kuadrat : 117. Kata kunci: Analisis, Double Exponential Smoothing, Memprediksi Permintaan.

Abstract

The rapid development of information technology in today's digital era has significantly impacted organizational performance, particularly in data management and resource planning. One organization that heavily relies on accurate data availability is the Indonesian Red Cross (PMI), especially its Blood Donor Unit (UDD). UDD PMI of Asahan Regency faces challenges in determining monthly blood donor targets to maintain stable blood stock. A shortage of blood supply can be fatal for patients requiring transfusions. Therefore, a system is needed to forecast the number of blood donors, allowing for more accurate decision-making. This study utilizes the Weighted Moving Average (WMA) method to predict the number of blood donors for the following month based on historical data from March 2024 to March 2025. The WMA method is chosen for its ability to assign greater weight to recent data, making the forecast more relevant and accurate. The results of this research are expected to assist UDD PMI Asahan Regency in anticipating blood needs and maintaining optimal stock availability.
