Abstract

Decreased air quality caused by air pollution can cause respiratory problems if inhaled for a long period of time. The absence of air quality monitoring equipment in the waste management area means that workers do not know the level of air pollution that occurs in the hospital area. This research aims to create an Air Quality monitoring system in the Hospital Waste Processing Area. The air that will be monitored is Methane, CO, Alcohol and NH4. Data on temperature, humidity, methane gas, alcohol gas, CO gas and NH3 gas are sent via ESP32 to the smartphone and sent directly to Google Sheet in real time, so that data acquisition from this tool is stored properly. Indoor measurements showed that Methane Gas showed an average of 40.9 ppm, then around the IPALL area Methane Gas rose to 81.0, this was because methane gas around the IPALL area had increased. Indoor measurements show that CO gas shows an average of 3 ppm, then around the IPALL area, CO gas increases to 165 ppm, this is because CO gas around the IPALL area has increased. Indoor measurements show that Alcohol Gas shows an average of 1 ppm, then around the IPALL area Alcohol Gas increases to 969 ppm, this is because Alcohol gas around the IPALL area has increased. Indoor measurements show that NH4 gas shows an average of 4 ppm, then around the IPALL area Methane Gas increases to 986 ppm, this is because methane gas around the IPALL area has increased

Abstract

Urinary Tract Infections (UTIs) can be identified through several indicators, such as difficulty urinating, weak urine flow, and low urine volume. To enhance the diagnosis and monitoring of this condition, a wireless-based uroflowmeter equipped with a thermal printer has been developed. This device utilizes a YF-S401 flow sensor to measure urine flow rate and volume, with pulse outputs processed by an Arduino UNO microcontroller. A Bluetooth module (HC-05) is used for wireless data transmission to an Android-based application (developed using App Inventor), while the measurement results can also be printed via a thermal printer. Volume testing demonstrated low error rates (0.33% – 1.53%), and flow rate testing produced results close to actual values. The device successfully connected wirelessly to the application and printed data accurately, indicating that it is suitable for supporting uroflowmetry examinations.
