Abstract

The increase in CO2 gas occurred very significantly due to the use of fossil fuels, industry, forest fires, volcanic eruptions and natural gas resulting in air pollution. The dangers of CO? gas for humans can cause headaches, sweating, blurred vision, tremors, and loss of consciousness after exposure for five to ten minutes. CO2 is a poisonous gas which is physically colorless and odorless. This characteristic causes many humans to be unaware of the existence of this gas, so that it is exposed and endangers health. Therefore we need a CO2 gas detection system. The difficulty that occurs in the detection of CO2 gas is when the gas is mixed with other gases that have similar material properties. In this research, a CO2 gas detection system is designed to detect the gas when it mixes with other gases using the MQ-135 sensor. The system that has been designed and built is then compared with a standard tool, namely the xm-7000 dragger. The test data analyzed using linear regression showed the results in accordance with 2the value of R = 0.9896 with the conversion equation y = 0.0389x-76.086. With these results provide new opportunities in testing CO2 on gas mixtures that are easier and cheaper.

Abstract

Since the emergence of Covid-19 in Indonesia in early 2020, it has spread throughout Indonesia, including rural areas. The Serut District, which is a border area, namely the Klaten district with Gunung Kidul, cannot be separated from the spread of Covid-19. The condition of the people of Serut Village, which is a genuine rural community, causes a lack of understanding of the dangers of the virus. The confusion of news in the mass media and social media has made the understanding of Covid-19 blurry. One of them is a non-invasive oxygen saturation detection system technology using an oximeter to monitor blood health conditions. This is very important, especially for patients who have confirmed Covid-19 and are self-isolating at home. In this service, the implementing team collaborates with the Serut Village government and the ranks of the Covid-19 task force to mitigate Covid-19 in the Serut Village area. The programs that will be implemented include providing materials and demonstrations for detecting oxygen saturation in the blood using an oximeter to the Covid-19 task force. The provision of materials and demonstrations will be continued with data sampling and analysis to the people of Serut Village. This program aims to introduce the system of measuring oxygen saturation in the blood and how to measure it independently. This is very important considering that oxygen saturation in the blood is one of the parameters in Covid-19 patients.  Keywords:  Oximeter; Blood Oxygen Saturation ;Satgas Covid-19; Kalurahan Serut
