The continuous expansion of modern shopping centers has created significant information barriers for consumers when searching for target stores. Paper-based directory maps only provide static floor plan information and cannot fulfill real-time, precise location-finding needs. This study aims to design and implement a Hybrid-based mobile directory application using the Scrum agile development method, with Grand Batam Mall as a case study. The Hybrid application is built using standard web technologies such as HTML, CSS, and JavaScript, enabling a single codebase to run on both iOS and Android platforms. The Scrum framework, through Product Backlog, Sprint Planning, Daily Scrum, and Sprint Review, enables rapid response to requirement changes and effective development progress control. The research was conducted through five stages: data collection, problem identification, requirements analysis, application design, and system implementation. Testing employed Black Box Testing to verify application functionality. The results show that the Scrum method effectively supports iterative development of the directory application, achieving a 100% pass rate in functional testing and maintaining development duration within the predetermined schedule. This study provides a technical scheme and process framework that can serve as a reference for the design and development of shopping center directory applications.

River water quality is a critical indicator of environmental health and ecosystem sustainability. In Indonesia, many rivers experience significant water quality degradation due to uncontrolled industrial, domestic, and agricultural activities. Conventional monitoring methods involving manual sampling and laboratory analysis are time-consuming, costly, and unable to provide real-time data. This study aims to design and build a web-based river water quality monitoring information system using Internet of Things (IoT) technology for early detection of environmental pollution. The system integrates pH sensors, TDS (Total Dissolved Solids) sensors, and temperature sensors connected to an ESP32 microcontroller, transmitting data wirelessly to a cloud-based server. The system was developed using the Waterfall methodology, consisting of requirements analysis, system design, implementation, testing, and maintenance. Features include real-time monitoring, automatic water quality classification, dashboard visualization, early warning notifications, historical data, and automated reporting. Data were collected through direct sensor measurements on river water samples over 30 days. Testing was conducted using Black Box Testing and User Acceptance Testing (UAT) with 30 respondents. The results show that the system successfully increases monitoring duration from 8 hours to 24 hours per day, improves pollution detection accuracy from 60% to 92%, and reduces problem detection time from 12 hours to 1 hour. The UAT results show a user satisfaction score of 4.36 (very good category). This study concludes that the web-based IoT water quality monitoring system is effective for early detection of river pollution and can be implemented in various locations with different river characteristics.
