Abstract

Palm oil mill (PKS) is a factory made from fresh fruit bunches (FFB) of palm oil which will be processed into palm oil or crude palm oil (CPO) and palm kernel (kernel). After the oil is seen to be separated from the sludge, the oil extraction process is carried out using an oil skimmer which is carried out manually by the operator so that it takes a long time and does not run effectively. The method of solving the problem is because so far it is still using the oil skimmer manually so a control system is needed for the oil skimmer so that it can take oil automatically using Arduino Mega 2560 as a control system and linear actuator as a motor that takes the oil. Based on the test results when the motor driver is given an input voltage, the output voltage value of the motor driver at the R_PWM pin is 4.94 V and the L_PWM pin is 4.93 V. Testing the linear actuator output voltage when the linear decreases by -11.45 V and when the linear increases by 11.53 V. Testing the output voltage on the push button when the push button start (green) is pressed at 4.97 V and when released is 0,02 V. The push button stop (red) is pressed at 0,02 V and when released is 4 .98 V. Testing the output voltage when the object approaches the proximity sensor is 5 V and when the object moves away from the sensor is 0.02 V, the average total error from ultrasonic sensor testing is 3.89%, and the overall tool testing is carried out 20 times and 18 times. times corresponds to 2 times does not match, it can be concluded that the accuracy of the tool is 90%.
