The increasing number of motor vehicles increases air pollution due to vehicle exhaust emissions containing hazardous substances such as carbon monoxide (CO), carbon dioxide (CO2), and hydrocarbons (HC). This system designs and builds a motor vehicle exhaust emission detection system, which can monitor air quality from vehicle exhaust, by developing a detection tool based on the Arduino UNO R3 …
The development of Internet of Things (IoT) technology provides opportunities in the development of automated systems for agriculture. The Smart Mini Greenhouse system based on the Internet of Things (IoT) is designed to monitor and regulate environmental conditions automatically to support the growth of vegetables plants, especially lettuce. This system uses an ESP32 microcontrollers as a cont…
Administrative services in faculty study programs require an effective queuing system to improve service quality. This research focuses on designing a queue number printer system that supports six counters, aiming to speed up the service process, minimize waiting duration, and increase user satisfaction. The methods applied include user needs analysis, hardware and software development, and ope…
Real-time river monitoring is crucial for increasing awareness of changes in river surface height and flow velocity, as well as helping reduce the risk of disasters such as flooding. One of the main challenges is heavy rainfall, which can cause sudden water rises. This research aims to design an Internet of Things (IoT)-based river flow and water level monitoring system. The system uses optocou…
The design of an efficient queue system is very much needed in administrative services to improve the convenience and effectiveness of services. This study aims to design and implement a six-counter queue display system using a P10 LED module panel in the administration room of the Faculty of Computer Science Study Program, Sriwijaya University. The design of this system includes hardware in th…
The availability of clean water that is stable and well-managed is a fundamental necessity, particularly in residential areas with independent water distribution systems, such as the one implemented in Griya Gerbang Emas Housing Complex. However, this system still faces challenges in monitoring water flow rates, pressure levels, and the service life of water filters, which are currently checked…
ABSTRACT Administrative services in faculty study programs require an effective queuing system to improve service quality. This research focuses on designing a queue number printer system that supports six counters, aiming to speed up the service process, minimize waiting duration, and increase user satisfaction.

This research developed a "Water Filter Cartridge Replacement Warning System Based on Flow Speed and Turbidity of Filtered Water" using Arduino Uno as a microcontroller. The implementation of the system is carried out using a waterflow sensor to measure water discharge and a turbidity sensor to measure water turbidity. Then the pressure value is obtained from the calculation of the linear equat…
Hydroponics is a soil-free agricultural system that relies on water as the primary medium for delivering nutrients to plants. To ensure optimal plant growth, regular monitoring of water level and nutrient concentration is essential. This study aims to design a web service-based monitoring system capable of displaying real-time data on water level and nutrient concentration. The system is develo…
