Development of Physical Distancing Detector (PDD) Integrated Smartphone to Help Reduce the Spread of Covid-19

摘要

The Government of Indonesia has issued rules on how to avoid covid-19 transmission, namely through various means including social distancing (SD) and physical distancing (PD), at least 1 meter. Until now to run the PD protocol based only on estimates, there has been no safe distance detection tool between humans. Therefore, the purpose of this research is to develop a safe distance detection tool in conducting a viable PD, named Pysical Distancing Detector (PDD. It consists of (a) ultrasonic sensor, (b) speaker, (c) Arduino, (d) Bluetooth, (e) battery, (f) micro. Physical Distancing Detector consists of a combination of components consisting of a lipo battery that can be recharged by the LIPO charger module. The electrical power generated by lipo batteries is used for microcontrollers (in this case used nano arduino). As for detecting the distance used by ultrasonic sensors, signals generated by ultrasonic sensors will be processed by microcontrollers. Ultrasonic sensors are mounted on the cap on the sides of the face - back and right - left of the hat. The result of this microcontroller is the sound emitted by the buzzer and the data sent by the Bluetooth module to the android gadget (HP) that has been equipped with software (applications). The results of this PPD test showed that the tool was meticulous at a "critical" distance of 1.5 m to 2 m. This tool can then be utilized in various people working in offices or strategic agencies that provide services to many people, such as health care, education, public services, public order (police), banking, food needs, oil and gas fuels, economy, communication, industry, export and import, distribution, logistics, and needs.
