SISTEM KONTROL ELEKTRIK PENGUKUR KEDALAMAN BANJIR PADA KAPAL MINI KATAMARAN

Flood is a natural disaster that occurs due to the increase in the volume of water. Flood measurement is needed in order to reduce unwanted accidents. Measurements that have high mobility are currently still using manual measurements. The measurement system that facilitates high mobility can be applied using a mini catamaran. Using a mini catamaran as a programmable flood depth gauge to measure flood depth directly. This flood depth measuring vessel has an IoT system to determine the water depth in a place that has many components for its control system. This study discusses the control system for mini catamarans as well as each component used, and how to measure the depth of air with ships using IoT. The flood depth measurement uses the MB7060 sonar sensor and the data acquisition process uses the NodeMCU Esp8266 microcontroller. Ship control system using a remote controller. The results are displayed in a smartphone application called Blynk. The process of measuring the depth of the flood is carried out by a mini catamaran. Before the ship operates the microcontroller with a smartphone, first use Wifi. Functional testing using manual measurement and MB7060 sonar sensor. The test results have an average of 120 cm on manual measurement of 120 cm, 229 cm on manual measurement of 230 cm, and 447 cm on manual measurement of 447 cm.
