e-Fungi: Using IoT to Monitor and Control The Growth of Fungi Causing Leather Goods Become Weathered

The leather industry is one of the small and medium industries that is experiencing rapid development in the Indonesian region. Even so, various problems apply to this business. One of them is related to the care that needs to be done on the leather which requires it to be stored in a place with a controlled temperature and environment because it tends to become a place for fungi growth. It is necessary to create an appropriate solution to help the problems that support the leather industry. e-Fungi will work as a system that can measure and control the temperature and humidity of a storage room for basic leather ingredients or products produced in real time. Also, the system will help and provide information about goods stock. This system will use DHT11 as a temperature and humidity sensor, bulb and DC fan as a temperature and humidity control system, an infrared sensor as a system for managing the number of goods, and the NodeMCU board module which will all be controlled using Arduino integrated via ThingSpeak. The results of system testing in the management of the number of goods have an accuracy value of 100% and the temperature and humidity sensor section has an accuracy of 95%. Meanwhile, the sending and reading of data by ThingSpeak web has a delay of 8.4 seconds and the percentage of error in the data transmission process is 4.7%.
