Abstract

The High level of organic matter in waste water from Sangkuriang catfish aquaculture is composed from feces and remaining feed. If the wastewater is directly flowed into public waters, it will increase the level of organic matter and cause eutrophication. This study was carried out as an attempt to decrease the level of total organic matter in the waste water from Sangkuriang catfish aquaculture. This study employed an experimental method with completely randomized factorial design and the data were analyzed by using Factorial ANOVA to reveal the differences in organic matter decrease for 120 hours (5 days). The main treatment was the addition of 50% and 75% attachment media of the experiment tank surface area. The additional treatments were 2 types of bacterial consortia from market products (bacterial consortium E and B). The organic matter was measured by using a KMnO4 oxidizer. The result indicated that the best decrease in organic matter was obtained in treatment with 75% attachment media and bacterial consortium E. In bacterial consortium E, the organic matter in the initial level was 64.464 mg/L and it decreased into 5.48 mg/L after 120 hours or there was 92% decrease. During the study, the water quality condition could support the lives of bacteria and other aquatic organisms. However, the carbon dioxide level from the reform of organic matter was high (39.6-159.72 mg/L). Thus, it is necessary to utilize carbon dioxide by involving autotrophic organisms such as plants in the management of organic matter.
