        abstract = {The Berseri Sejahtera Waste Bank in Cilacap still relies on manual record-keeping,
which causes slow administration, makes data vulnerable to loss, and lacks
transparency for customers. The waste collection service is also not systematically
managed. This research aims to design a web-based information system to
digitalize operations and overcome these obstacles. The system development
utilizes the prototype method through two iteration cycles. Cycle I focuses on the
core functionalities, including user management, transactions, waste collection,
and reporting. Based on the final evaluation of Cycle I, the development in Cycle II
was conducted by integrating the WhatsApp Gateway API from the Fonnte server
for real-time notifications, as well as optimizing the reporting filter using the
Carbon library. The system was successfully implemented and proven to improve
operational managerial efficiency. Functionality testing using Black Box Testing
demonstrated a 100\% valid success rate. Meanwhile, code logic testing using White
Box Testing on the deposit feature resulted in a cyclomatic complexity value of V(G)
= 3, where all logic paths were tested as valid, including the execution failure
scenario (database rollback).}
