Abstract

Fruit stores face the challenge of determining optimal prices to maximize profits while considering stock constraints, costs, and demand. This research uses a linear programming approach with the simplex method to solve this problem. The data used includes reseller prices, selling prices, stock capacity and market demand for seven types of fruit. The manual process with the simplex method was validated using QM for Windows software. The research results show that this method is successful in determining the optimal combination of selling price and production quantity, which provides a maximum profit of IDR 666,000 per day. This approach provides a strategic solution for fruit shop managers in making data-based decisions.

Abstract

The rapid development of Internet of Things (IoT) and cloud computing technologies has significantly transformed the way organizations manage information. Management Information Systems (MIS) are no longer limited to data recording and reporting functions but have evolved into integrated systems capable of providing real-time information to support strategic decision-making. This article aims to examine the role, benefits, and challenges of implementing Management Information Systems in the era of IoT and cloud computing. The research method employed is a literature review, drawing on relevant journals, books, and scientific publications. The results indicate that the integration of IoT and cloud computing into MIS can enhance operational efficiency, data accuracy, and system flexibility. However, several challenges remain, particularly related to data security, privacy issues, and the readiness of human resources.
