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

The advancement of information technology has significantly contributed to innovations in the health sector, including the development of digital tools that support nutrition management and healthy lifestyle practices. One essential aspect of maintaining health is managing daily caloric intake based on individual metabolic needs, which are influenced by factors such as age, gender, height, weight, and physical activity. However, many individuals are unaware of how to accurately calculate their caloric requirements. Therefore, a practical and accurate system is needed to provide personalized calorie recommendations.This study presents the design and development of an Android-based calorie calculator application that estimates daily energy needs using user inputs: age, gender, height, weight, and activity level. The application integrates two well-known formulas—Harris-Benedict and Mifflin-St Jeor—to calculate Basal Metabolic Rate (BMR) and determines Total Daily Energy Expenditure (TDEE) by categorizing physical activity as light, moderate, or intense. In addition, the app includes a Body Mass Index (BMI) calculator to indicate the user's nutritional status. Developed using the Kotlin programming language in Android Studio, the application is designed with a user-friendly interface to enhance user experience. Functionality testing demonstrated that the application provides accurate estimations of caloric needs and reliable BMI categorization based on user input. The outputs are consistent with results from existing online calorie calculators, confirming its precision and usability. This calorie calculator application is expected to function both as an educational and practical tool for individuals seeking to adopt a balanced diet and effective weight management strategy.

Abstract

The bacterial incubator plays a crucial role in culturing microorganisms, particularly in biotechnology research and its applications. This research focuses on the development of a bacterial incubator system utilizing the Arduino Mega2560 microcontroller, operating within a temperature range of 35°C to 50°C. The system incorporates a BME280 sensor for temperature and humidity detection, a TFT touchscreen LCD for user interaction, and an integrated control mechanism for regulating both temperature and incubation duration. Performance testing involved comparing sensor readings from the prototype against standard measuring devices, yielding an average temperature deviation of 0.61%, indicating reliable and precise performance. The device also features automatic regulation of environmental conditions and real-time data visualization, ensuring consistent incubation settings based on predefined criteria. Overall, testing confirmed that the incubator performs effectively and aligns with the intended design parameters.
