THE INCREASING OF OXYGEN LEVEL USING AERATORS IN A FISHPOND AT YAUMIDDIN ORPHANAGE, KARANG JOANG, NORTH BALIKPAPAN

Abstract

Fishing area is one of the favorite tourist attractions for Balikpapan’s and surrounding area residents. One of the fishing areas that has just opened is fishing area at the Yaumiddin Orphanage. However, there is a problem about the quality of fish meat due to low oxygen levels in the pond. The solution of this problem is by installing an uniring aerator. However, there were some obstacles when installed the aerator one of them is because the aerator is light and floats, so it needs an additional stone as the ballast. The obtained value for oxygen levels at the pond with temperature 3000C before the aerator installed is 24.3 mg/L. After the aerator installed, the oxygen level increased to 27.1 mg/L. It proves that the aerators can increase the oxygen levels and it can also improve the quality of fish which is in breeding process.
