Abstract

ABSTRACTThe purpose of this research is to design and make a real tool in the form of a drying cabinet for cocoa beans. Because this solution can relieve the farmers who previously drained the cocoa beans in the sun. This drying cabinet uses the Arduiono Uno 328P control and heater element as a heater. This cabinet is also equipped with a DC motor mechanical device to drive the cocoa drying container. This tool is also equipped with a DHT12 sensor which is a resistive sensor whose value changes depending on the water content of the cocoa beans. The sensor plays a role in detecting the temperature and humidity of the seeds in the cacao drying room. Then the output inverting amplifier voltage is read by the ADC Arduino UNO 328p microcontroller, which is then processed and displayed on the LCD. The test results showed that the measuring instrument made was able to measure the amount of water contained in cocoa beans in the range of water content measurement from 60% to 7.5%. Keyword: Cocoa Beans, Temperature, Arduino, DC Motor, DHT Sensor

Abstract

Today's technological developments are growing rapidly, but there are still jobs that are done manually and semi-manually. This paper aims to develop a control system to coordinate the work of tools using an electric motor, which is very helpful in the process of cutting onions in large quantities and is more efficient in spending production costs because the tool designed is an automatic onion cutter. This research method begins with the collection of materials and data related to onion cutters, production of onion cutters, and testing of onion cutters. The measurement results of the tool show that every component in the automatic onion cutter works well and optimally; the measurement process is carried out properly and thoroughly. This optimal work result is supported by Arduino Uno. The Arduino Uno microcontroller acts as a tool controller. In the main system, the onion cutter is controlled by the Arduino Uno with the Arduino programming language. This automatic onion cutting system will work when the onion you want to cut has been inserted into a cross-section that has been equipped with an ultrasonic sensor, and then the onion cutting process is carried out. Compared with the manual method, the cutting time is almost the same. It's just that the advantages of slicing with this tool, the resulting slices are relatively more uniform. Besides that, another advantage is that it doesn't hurt the eyes of the onion slicer. So that this tool can be used by small entrepreneurs and onion farmers to increase productivity and the community's economy.
