Abstract

Meningitis is generally an infectious disease of the lining of the brain and spinal cord with manifestations of fever and stiff neck. Prevention efforts for meningitis include vaccination. Meningococcal polysaccharide vaccine (MPSV4) is a type of quadrivalent meningitis vaccine recommended to control meningitis outbreaks. In storage, this vaccine uses a cold chain and cool box with a temperature between 2-8˚C. For vaccination activities, the vaccine is stored in a cool box with a cool pack provided to maintain temperature stability in the cool box. A cool pack itself is a rectangular plastic container that is filled with water and then cooled in a refrigerator at a temperature of 2-8°C for a minimum of 24 hours. From the existing problems, the author had the idea to create an IoT-based MPSV4 Meningitis Vaccine Cool Box Temperature Monitoring and Controlling System Design. The working system of this tool, namely TEC, will maintain the cool box temperature according to needs. If the dht11 detects that the temperature is too high then both TECs will turn on, whereas if the temperature is stable then one of the TECs will turn off. The temperature inside the cool box will be displayed on the LCD and also sent via the NodeMCU ESP8266 to the Firebase database which will then be displayed on the smartphone in real time.

Abstract

The availability of clean water is a crucial factor in supporting sanitation and health in Islamic boarding schools, especially for bathing, washing, and toilet (MCK) facilities. Pondok Ma’had Al-Aqwam MAN Kendal faces poor water quality issues, such as murky water, unpleasant odors, and unsuitable acidity levels. This study aims to develop an Internet of Things (IoT)-based water quality monitoring information system to support real-time sanitation management in boarding schools. The system is designed using an ESP32 microcontroller integrated with pH, turbidity, and temperature sensors, displaying data directly through the Android-based Blynk application. It also includes an automation logic that activates the filtration pump when the pH or turbidity values fall outside the normal range. Testing results indicate that the system can accurately read and display water conditions and perform automatic re-filtration when water is deemed unfit for use. Expert and user validation yielded an average score of 90%, indicating the system is highly feasible for clean water management in boarding schools. Therefore, this system offers a practical and efficient solution for continuously monitoring and maintaining water quality.

Abstract

This article discusses the design of a smart trash bin system based on a microcontroller that can provide real-time notifications via the Telegram application when the trash volume reaches its maximum capacity or when unpleasant odors are detected. The system is designed to enhance the efficiency of waste management in an elementary school environment in Central Java, Indonesia. The developed device utilizes two ultrasonic sensors to detect object proximity and trash volume, as well as an MQ4 sensor to identify methane gas as an odor indicator. The NodeMCU serves as the central controller and network interface for sending notifications to Telegram. Testing results demonstrate that the system effectively detects the trash bin's condition and delivers timely and automated notifications to cleaning personnel. This innovation is expected to serve as a practical and effective solution in supporting a cleaner and healthier school environment.

Abstract

This study aims to develop a web-based inventory information system to improve operational efficiency and data accuracy at Toko Linnia Collection. The research method used is Research and Development (R&D) with a prototyping approach. The system was developed using PHP programming language and MySQL database, and includes key features such as automated stock recording, PDF reporting, and multi-user role management. The implementation results show a 65% improvement in recording efficiency, a significant reduction in data entry errors, and easier system access for both the owner and employees. Based on blackbox testing, all system features function as expected. In conclusion, the system effectively addresses the real needs of inventory management in MSMEs and provides a practical and reliable solution for inventory digitalization.
