Abstract :

This corn drying is done to increase the storage capacity and increase the economic value of the corn and the corn used has been shelled by reducing the water content to a maximum of 14% if the corn is said to be dry. The heating element here is very important to accelerate drying, the more elements used, the faster the time required for the drying process. To detect room temperature and humidity, a DHT11 sensor and a water content sensor are needed to determine the water content in the corn. The research method used in writing this article is a literature study by comparing the results of water content sensor measurements in experiments according to SNI. The results of the lowest water content measurement which has a water content of 13.4% with a time of only 120 minutes and 100 g of corn. The study of the water content value with the lowest value in the test can be used as a reference for designing a corn dryer prototype with a heating element using a DHT11 sensor and an Arduino Uno-based water content sensor.
