<![CDATA[The Laundry Unit of Assalaam Islamic Boarding School, Surakarta, continues to encounter challenges in managing member data, laundry transactions, payment processing, and report generation because these operational activities are handled separately. This fragmented process increases the risk of recording errors and reduces service efficiency. This study aims to develop a web-based Laundry Information System that integrates data management, balance top-up payments, pending transaction processing, and membership management to improve the effectiveness and efficiency of laundry services. The system was developed using the Waterfall software development methodology, consisting of requirements analysis, system design, implementation, testing, and maintenance. Laravel was employed as the development framework, with PHP as the programming language, MySQL as the database management system, and Unified Modeling Language (UML) for system modeling. The developed system successfully integrates student member management, laundry transaction processing, balance top-up payments, pending transaction handling, laundry staff management, receipt generation, and reporting into a single web-based application. System functionality was evaluated using Black Box Testing, which confirmed that all features operated according to the specified requirements. Furthermore, User Acceptance Testing (UAT) produced a user acceptance rate of 94.07%, indicating a high level of user satisfaction with the developed system. The implementation of the proposed system improves service speed, enhances the accuracy of data and transaction management, and increases the efficiency of report generation. These findings demonstrate that the system is suitable for implementation at the Laundry Unit of Assalaam Islamic Boarding School, Surakarta, and has the potential to support more effective and reliable operational management.]]>
