| dc.description.abstract | This research develops an automatic fish feeder using a combination of time parameters and pH levels based on IoT (Internet of Things). The pH level is one that affects the condition of the water in the survival of fish. Components that complement this automatic fish feeder are RTC, LCD, servo motor, power supply, pH sensor which functions to measure pH levels in fish ponds and Arduino uno which functions to control and process input device data to output as well as the use of IoT (Internet of Things) as a control that can control the pH level of pond water remotely. The results showed that the pH sensor had good accuracy with a maximum % error in a pH 7 solution of 0.71 and a maximum % error in a pH 9 solution of 3.66%. In addition, research shows that the system can control the pH value of the pond, which ranges from 6.44 to 7.21. In this study, an experiment was also carried out to measure the pH value of the pellet water that had been deposited for three weeks and to measure the pH value of drinking water which was divided into six portions of the sample where the accuracy of the pellet water pH level ranged from 2.45 to 4.27 and the accuracy of the water content of the pellets was The pH of the water ranges from 6.50 to 7.07. The development of this tool is very helpful for fish farmers in controlling pH levels in fish ponds and feeding fish automatically. | en_US |
