This system design aims to develop a web-based tourism information system for Bungus Teluk Kabung sub-district office and create applications that can be implemented in this sub-district office. This system research method is built on a website platform and runs online. The research method uses the system development life cycle (SDLC) with the waterfall model approach, which consists of 5 phases, namely: a) Analysis b) Design c) Implementation d) Maintenance e) Planning. The programming language used is (PHP), and the database application uses a data processor (MySql) as the database (RDBMS). The system design tools use Unified Modeling Language (UML) method with 4 (four) diagrams according to the design requirements, namely use case diagrams, activity diagrams, class diagrams and sequence diagrams. The tourism information application in the sub-district office of Bungus Teluk Kabung facilitates visitors to find information and tourist places in the study area.
