INTELLIGENT COCOA DRYER TECHNOLOGY BASED ON AN EMBEDDED SYSTEM

Abstract

Technology has become a basic need for humans, which is used by all groups from children to adults, experts and non-experts, in various aspects of their lives. Every innovation is created with the aim of having a positive impact on human life. Cocoa (Theobroma cacao L.) is a plant originating from South America. And cocoa is one of the mainstay commodities of the plantation sub-sector with high economic value and plays an important role in the development of plantations in Indonesia. However, the drying process still uses heat from sunlight, so whether the drying process takes a long time or not really depends on the intensity of the sunlight shining on it. With the Embedded System concept implemented using a microcontroller, embedded systems can provide real time responses. To be a solution for drying cocoa without sunlight and being able to see the temperature and moisture content of the cocoa, the tool "Intelligent Cocoa Drying Technology Based on an Embedded System" was created. In this research, Arduino Uno is used as a microcontroller, a DHT22 sensor to detect the heat temperature in the box, an RTC DS3231 to carry out scheduling and a SoilMoisture sensor to measure water content after drying and a motorbike battery as an electricity backup in the event of a power outage.
