Abstract
The manual cassava slicing process that is still widely used is often time-consuming, unsafe, and dependent on human power. Most cassava slicing tools currently use human power to insert cassava and move the cutting knife, which can cause work accidents if not careful in operating it. Another thing that affects is when there is a power outage that causes the tool to stop operating, thus inhibiting the cassava slicing process. Therefore, a safer and more practical cassava slicing tool will be developed to increase productivity by utilizing a DC motor as the main driver, whose energy is supplied by a battery. With a semi-automatic system, cassava will be pushed by a linear actuator towards the cutting knife driven by a DC motor. This tool will later be supported by a proximity sensor that allows detection of the presence of cassava, so that the tool can only work when cassava is available. The battery functions as an energy source that can provide temporary power during a power outage and ensures that the device continues to function so that it can provide flexibility in its use. Use of the L298N motor driver to control the rotational speed of the DC motor on the linear actuator. The test results show that, the DC motor and battery-based cassava cutting tool is able to operate for 45 minutes without load and 30 minutes with load, with energy consumption increasing over time due to voltage and power reduction due to battery capacity weakening. The PZEM-017 sensor shows good measurement accuracy, with a voltage difference of 0.36–0.76 Volts (maximum error 4.264%), the highest current difference of 0.13 Ampere (error 2.995%), and a power difference of 2.41 Watts (maximum error 6.624%). The decrease in RPM and cutting speed is an indication of decreased mechanical efficiency due to reduced energy supply. As long as the voltage and current are still within optimal limits, the tool is able to cut cassava well and the results are stable.
