Abstract
During the pandemic the learning process was conducted online and partly done face-to-face so that every day there are still students and employees who are in the campus environment. One of the prevention of covid transmission is done by spraying disinfectant when passing through the front gate of the campus. A design a prototype of an automatic disinfectant spray system and build a system on the prototype that can provide real time information related to monitoring the contents of the disinfectant tank by designing hardware. The results of the research built a disinfectant spraying automation system in front of the entrance gate of Universitas Musamus, to get results that prove that the system performance has been running as expected, there are several tests carried out such as tool testing and measuring the reading distance of the ultrasonic proximity sensor, and testing. sending SMS alert. How to provide information that the liquid in the tank has run out. Sensor sends a status signal for the disinfectant liquid level after spraying, a warning SMS is sent went the distance of disinfectant liquid and the ultrasonic sensor at a predetermined threshold.
Highlights
Universitas Musamus is a public university in Merauke, Papua which was established on August 16, 2006
Based on the results of interviews with the team for making disinfectant sprayers on June 12, 2020 at Universitas Musamus, it was revealed that the equipment designed for spraying disinfectant liquid and filling water into the storage tank works manually, when the switch is on, the water pump will immediately work spraying, and when the switch is turned off, the pump will go out
PIR (Passive Infra-Red) sensor : When someone walks past the sensor, the sensor will pick up passive infrared rays emitted by the human body which has a different temperature from the environment so that the device can spray disinfectant
Summary
Universitas Musamus is a public university in Merauke, Papua which was established on August 16, 2006. Based on the results of interviews with the team for making disinfectant sprayers on June 12, 2020 at Universitas Musamus, it was revealed that the equipment designed for spraying disinfectant liquid and filling water into the storage tank works manually, when the switch is on, the water pump will immediately work spraying, and when the switch is turned off, the pump will go out. The previous weakness was not being able to provide information to users when the water in the tank was running low, it was necessary to design an automatic disinfectant spraying device at the gate of Universitas Musamus so that the spraying process could be maximized so as not to spend a lot of money in using disinfectant liquid. It can provide information to personnel when the water in the tank is running low
