Abstract

The advancement of information technology has driven educational institutions to enhance the efficiency and quality of both academic and non-academic services through more integrated survey systems. Universitas Muria Kudus (UMK) still relies on manual survey methods, leading to data duplication, input errors, and delays in analysis. This study aims to design and develop a centralized questionnaire information system to improve survey management efficiency. Using the prototype method, the system was developed in two cycles: the first cycle included core features such as a dashboard, questionnaire management, reporting, and a login system, while the second cycle refined functionalities, including input validation, answer variations, search filters, and report export capabilities. BlackBox Testing was conducted to ensure optimal system functionality. The results indicate that the proposed system enhances efficiency, minimizes data errors, and accelerates survey result analysis, ultimately contributing to improved academic and non-academic services at UMK.

Abstract

Manual stock management, particularly through paper based record keeping, remains a challenge for culinary businesses such as Kava Coffee Shop in Kudus. Issues such as inaccurate records, delayed reordering, and the absence of notifications for expired or damaged ingredients can lead to stockouts or overstocking. This study aims to design a web-based inventory information system incorporating the Safety Stock and Reorder Point (ROP) methods to optimize the management of perishable raw materials. The system was developed using the Waterfall model, covering requirements analysis, design with Use Case and Activity Diagrams, feature implementation, and testing through the Black-box method. Key system features include minimum stock notifications, expiration tracking, transaction management, and damaged goods returns. Testing results show that the system performs according to specifications, achieving a 100% success rate across functional scenarios. Compared to previous studies, this system demonstrates superiority by being web-based, focusing on perishable goods, and offering integrated features. Therefore, the system can enhance record accuracy, accelerate decision-making, and ensure the availability and quality of raw materials at Kava Coffee Shop.
