Design And Build Of Temperature Control System To Increase The Growth Rate Of Neon Tetra Fish And Egeria Densa Plant In Aquascape

In maintaining an aquarium or aquascape, water is the most important element and must be properly maintained for the survival of living things such as fish and aquatic plants. Living things in an aquascape will live well if the water used in the aquascape is of good quality. Currently Aquascaping is a trend and a hobby among aquatic environmentalists and fish fans because it is a form of entertainment to relieve stress after work and the art of raising fish. However, caring for the aquascape itself tends to be difficult because you have to consider parameters that are appropriate for the biota in it, such as the temperature that must be maintained in the aquascape. Therefore, in this final project, an Aquascape with a temperature control system will be made by monitoring PH and dissolved oxygen which is equipped with a Cooling Peltier and HPL Lamp to maintain the temperature in the Aquascape. The sensors used to measure temperature, PH, and dissolved oxygen are the DS18B20 sensor, 4502C pH sensor and DFRobot DO sensor. Temperature control is carried out by NodeMCU ESP32 using On-Off control and is equipped with a monitoring system via a smartphone. The control system in Aquascape works by maintaining the temperature at a set point of 22-25℃. If the temperature measurement results do not match the set point, the Peltier actuator will turn on to adjust the temperature to match the set point. This final project also uses HPL LEDs to help plants in Aquascape carry out photosynthesis. The results of this final project obtained the growth rate of Neon Tetra fish using a control system, namely the growth in length of the fish is 3.5 cm and the result of long growth without using a control system is 3.2 cm. It can be concluded that to increase the growth rate, a temperature control system can be used in Aquascape.
