Design and Development of a Flood Detection Device for Drainage Systems Utilizing Float Switch Water Level Sensors

Abstract

Indonesia ranks second in Asia Pacific in the list of the highest number of deaths due to natural disasters. In a year, more than 300 flood events occur, resulting in large losses, environmental damage and even loss of life. To overcome this problem, it is necessary to design a tool for monitoring water levels and rainfall. This research aims to design a flood detection system using the fuzzy method and using a float switch water level sensor. The results of the research show that this system can monitor water levels and rainfall using a web server. In the first test, it produces a fuzzy warning level in a safe condition. In the second test, the water level reached 51 cm with rainfall of 0.47 mm, and the fuzzy warning level was in a safe condition. Finally, in the third test, the average water level reached 99 cm with rainfall of 0.69 mm, resulting in a fuzzy warning level in an alert state. It can be concluded that this system needs to be improved in quality by adding items to the system.
