Abstract

The public service management system at the Ministry of Religious Affairs Office, Jayapura Regency, remains reliant on manual processes, resulting in inefficiencies such as prolonged processing times, data redundancy, and challenges in tracking service requests. This study aims to design and develop a web-based Integrated One-Stop Service (IOSS) system to enhance service efficiency, accuracy, and accessibility. The Rational Unified Process (RUP) methodology was employed as the system development framework due to its structured, iterative, and flexible approach to managing the software development lifecycle. The design phase commenced with a needs analysis conducted through in-depth interviews with employees and service users to identify system requirements and existing challenges. The system design encompassed the development of an intuitive user interface prototype and a comprehensive database to support IOSS operations. System evaluation through black box and usability testing methods yielded a 100% functionality success rate and a user satisfaction score of 4.46 on a scale of 1 to 5, indicating that the system operates effectively. The findings demonstrate that the developed system significantly improves public accessibility and satisfaction with government services. This study contributes to the advancement of public service digitalization, fostering a more efficient and responsive service delivery system.

Abstract

Water level is an important parameter in monitoring hydrological dynamics, particularly in drainage channels, as significant changes can trigger flooding and disrupt public activities, including in the Faculty of Mathematics and Natural Sciences (FMIPA) campus at Sam Ratulangi University. This study aims to design and implement an early warning system for water level based on the Internet of Things (IoT) that can provide real-time notifications via Telegram. The system utilizes the ESP32 microcontroller, HC-SR04 Ultrasonic Sensor, and Raindrop Sensor to detect rainfall and measure water levels in the drainage channel. The system is designed using the Waterfall model and tested with a black-box approach. Notifications are automatically sent to Telegram when the water level status reaches the "Alert" or "Overflow" category, and will stop once the status returns to "Safe." The test results show that the system functions accurately, the network connection is stable, and notifications are sent in a timely manner. This study contributes to local flood mitigation and enhances the preparedness of the academic community towards rising water levels.
