Abstract

Environmental health is one of the most important and influential things for human life and health. A clean and healthy environment will make every individual around him comfortable and improve the quality of his life. Public toilets are part of the environment whose existence is very important. The poor quality of public toilets facilitates the transmission of bacteria and the development of germs. Based on these problems, a tool is made that can be used to classify the quality of public toilets based on the threshold that has been determined by the government. In this study, the parameters used in monitoring the quality of public toilets are odor, humidity, and temperature in public toilets. Where for the odor parameter is ammonia gas. This gas is a gas that is often produced by human activities while in public toilets. The process of determining toilet quality through ammonia gas, humidity, and temperature is obtained from the readings of two sensors, namely the MQ135 sensor and the DHT11 sensor by the Arduino Uno microcontroller using the Threshold method. The use of the Threshold method was chosen as a decision-making technique for public toilet conditions because it has high accuracy, where the classification of the types of general toilet conditions has been known from the start. From the results of several times testing the readings of two sensors using the Threshold method, MQ135 has a high correlation with environmental conditions, and DHT11 has a fairly high correlation with environmental conditions, with data retrieval 10 times. (After that at the very bottom, include keywords or keywords of 3-5 words.)
