THE PROTOTYPE OF AQUARIUM WATER QUALITY MONITORING SYSTEM

One of the Indonesian people's hobbies is keeping ornamental fish. Ornamental fish are kept in ponds or aquariums. One thing that is very important to consider in maintaining ornamental fish in an aquarium is water quality. Dirty water quality can inhibit the growth and development of fish. The optimal temperature range for the life and development of aquatic organisms ranges from 25 to 35oC, while the acidity level in the aquarium model is at pH 6.8-7.5 [7]. Turbidity does not use NTU units but is as a voltage that is read by the sensor. If the low voltage is below 1 volt or less than 2 volts, then the water is said to be cloudy, but if the voltage is above 2 volts, then the water is declared clean [2]. The fuzzy algorithm will process data from the sensor, which is used to determine whether the buzzer is on or off. With this tool, it will be easier for the owner to monitor the aquarium water.
