Abstract

The purpose of this research is to design and implement an automatic acrylic carving and cutting tool using a microcontroller-based 3-axis CNC machine. Computer Numerical Control (CNC) is a machine technology that is operated automatically to support the demand for a product that has a complex shape and high accuracy. In general, the construction of a 3-axis CNC machine and its working system is synchronization between the computer and its mechanics. This tool has a work process by utilizing the G-Code method as a command on the machine to carry out engraving and cutting automatically. The G-code was obtained from a previously designed image and then converted using the Aspire 9.0 software. Engraving and cutting is done by sending the G-code file to the microcontroller via the Universal G-code Sender software, then the microcontroller sends a signal to drive the motor driver which then drives the stepper motor so that the actuator movement is generated according to the image in the G-code file. Simultaneously the spindle motor will be active to engrave or cut acrylic. In this study, a trial scenario was carried out to determine the precision and accuracy of the tool, namely by engraving and cutting flat shapes such as squares, circles, triangles and segments. The percentage of success generated from this tool is 97,08% to 100%. Furthermore, testing is carried out to make products in the form of engraving writing, logos and calligraphy. Apart from that, we also tested cutting letters and key chains. When the test is carried out, the accuracy level is 1mm.

Abstract

Positive cases of COVID-19 continue to grow rapidly. This prompted the government to make new rules in the form of various types of health protocols. One of them is the implementation of the self-isolation protocol for confirmed COVID-19 patients. Self-isolation is a rule that requires confirmed patients to stay at home until the specified time limit to break the chain of COVID-19 development. However, it is suggested and as a rule that there are still many ODP and PDP who still violate the rules of self-isolation from the government. The ODP and PDP still roam freely without thinking about the impacts and risks to their surroundings. With the departure of confirmed patients, the risk of developing COVID-19 becomes greater. In this study, a confirmed patient locator bracelet was made that can map the position of the patient based on latitude and longitude. The latitude and longitude data from the bracelet is sent to the gateway by LoRa communication. LoRa communication is also used to minimize the dimensions of the bracelet. In addition to mapping the location of the patients, by applying the Heversine method this system is able to identify when a safe zone violation occurs in the form of a change in the color of the marker. In the future, it is hoped that this system will be able to handle the problem of developing COVID-19 caused by confirmed patients who still violate the self-isolation protocol.
