Abstract :
Koi fish (Cyprinus carpio) is a type of ornamental fish with high economic
value. Water quality management is an important component for the cultivation of
ornamental fish, and especially koi fish. The quality of koi fish depends on the
oxygen content in the water, the pH and also the dissolved solids in the water. The
filter media as a water quality control utilizes a pump to raise the water. The
addition of solar panels for independent energy for koi fish cultivation media can
reduce the cost of electrical energy used. The test results show that the maximum
power value produced by the panel at 12.00-15.00 is 4.919 Watt. While the
maximum power required by the pump is 9.728 Watt. The energy of the pump in
one day is 27.67 Wh and the total energy of the solar panels in one day is 52.8
Wh.
