Abstract

The adverse effects of air pollution on human health, climate change, and ecosystems have made air pollution a major problem in the last four years. Ammonia is a pollutant that has an impact on human health. This study aims to develop a monitoring system for NH3 concentrations using radio communication. The radio module used in data communication is SX1278. The sensor used in this system is MICS-6814, which is integrated with Arduino Nano. The sensor used has been tested and can be used in emission detection. Monitoring results data is displayed on the LCD and serial monitor. Data communication performance for the monitoring process was tested at various distances. This system can reach a measurement distance of 80 meters, with the best distance used for monitoring being less than 50 meters. This system was tested to be able to monitor a different level building. The result shows that the system's performance is the RSSI at a distance of 0 meters is -28 dBm. At the same time, the farthest distance of 80 meters is -101 dBm. The data transmission has a delay time of 1,300 ms and an accuracy of 91%. The ambient NH3 concentration in the area of Malang is found in the range of 0.001 ppm.

Abstract

Ethanol is beneficial for the sterilization process and increases the rate of photosynthesis. Measurement of ethanol concentration is necessary because ethanol in high concentrations can cause several health problems, such as eye irritation, coughing, lacerations, and ineffective plant sterilization processes. Therefore, a sensor-based measurement system is needed to measure the total gas concentration in liquid organic fertilizer. This research aims to characterize the MQ-8 sensor and analyze the ethanol concentration for the fermentation process. The results of this study indicate that the MQ-8 sensor can work well in measuring the concentration of a single ethanol compound with an accuracy of 91%. The total concentration of ethanol gas in each sample liquid organic fertilizer is measured between 216 ppm to 1583 ppm, depending on the fermented plant.
