Perancangan Sistem Informasi Penjualan dengan Metode Single Exponential Smoothing untuk Perencanaan Produksi

Studi Kasus: Mamis Bakery Bengkayang

Abstract

The development of information technology has encouraged business owners to utilize systems that can support data management and decision-making processes more effectively. One of the common problems faced by Micro, Small, and Medium Enterprises (MSMEs) is that sales recording and production planning are still carried out manually, making it difficult to determine production quantities that match market demand. This condition also occurs at Mamis Bakery Bengkayang, where sales data recording has not been managed systematically and production quantities are determined based solely on estimation without a clear calculation method. This study aims to design and develop a web-based sales information system integrated with the Single Exponential Smoothing (SES) method to support production planning at Mamis Bakery Bengkayang. The research method employed is software engineering with a quantitative descriptive approach. The developed system is capable of managing product data, customer data, sales transactions, customer orders, and forecasting processes based on historical sales data. The SES method was selected due to its simplicity and effectiveness in predicting fluctuating sales data. System testing was conducted using the black box testing method to ensure that all features function according to user requirements. The results indicate that the developed system is able to improve the management of sales data, accelerate report generation, and produce sales forecasts that can be used as a basis for determining production quantities in subsequent periods, thereby supporting more effective and efficient decision-making processes.
