Abstract
The nature of soda ash dissolves in water and is alkaline, reduces the color at the level of air coloring, and reduces the water content. Alum (potassium aluminum sulfate) is an excellent mordant to add to water because it is harmless except when ingested in large quantities, it forms white crystals or powder. The chemical properties of alum are soluble in air (hydroxyl groups), insoluble in ethanol and acetone which can purify the air. With the development of technology, humans can easily monitor remotely pouring soda ash and alum intoair reservoirs using the internet of things (IoT). The purpose of this research is to create a tool that can monitor the distance that works on air reservoirs through the Blynk application. The tool works when the HC-SR04 ultrasonic sensor detects the distance from the soda ash and alum ultrasoke sensor, the sevo motor opens the pourer at the bottom of the tube. The ultrasonic level data stored in NodeMCU is then sent to the Blynk server. The Blynk application is used to carry out monitoring tools by testing ultrasonic sensor levels. From the results of ultrasonic sensor testing 1, an average error of 2.32 % is obtained, so the accuracy is 97.6 % and for ultrasonic sensor 2, an average error is 3.55 %, so the accuracy is 96.4 %. The test results for servo motors 1 and 2 show an accuracy of 56,3 and 55,6 %. Based on the results of the NodeMCU test conducted, this tool with data at a distance of 80 meters is still connected to Wi-Fi, while a distance of 85 meters is no longer connected to Wi-Fi with NodeMCU ESP8266.
