MONITORING PH AIR BUDIDAYA IKAN LELE

Abstract

Water PH for Catfish ranges from 7 to 8. Catfish is one of the economically valuable animals, so many fishfarmers who choose catfish as the object of his farm. One of the obstacles faced by catfish farmers is the setting up ofmealtimes and the maintenance of water quality. This causes the farmer must always be vigilant for the quality andweight of catfish farms are kept awake. In this study, the authors designed a tool that can help catfish farmers to be ableto improve the quality of the harvest without having to always observe the catfish in the pond farm. The main controllertool in this tool is Arduino Uno. PH sensor is used to measure whether the PH of fish pond water is still normal or not.The measurement of water quality parameters in this tool is the level of water acidity (PH of water). For this purpose awater pH sensor is used. This tool is also equipped with a bluetooth module which functions to monitor PH through anandroid device. Measurements show an alkaline pH of 7.19 and this range of bluetooth is 5-10 meters.
