Analysis predicts sales fluctuations in a peanut cake business, suggesting strategies for raw material management.
UD. Anugrah Exclusive is a peanut cake home industry in Binjai City that faces monthly sales fluctuations so that it has an impact on the management of raw material stocks. This study aims to build a sales prediction model using a simple linear regression method with sales data for the period January 2021–June 2025. Independent variables are in the form of time (months) and dependent variables are in the form of sales (pouch). The model is implemented in a web-based system using Python and MySQL and evaluated using Mean Absolute Percentage Error (MAPE). The results of the study resulted in a regression equation Y = 349.55 + 2.55X with a MAPE accuracy rate of 9.03%, which is in the very good category. The system built can help business owners estimate raw material needs, avoid the risk of overstock or lack of stock, and develop a more appropriate marketing strategy.
