Utilization of semi-aerobic bamboo lid to decrease organic matter

Abstract

Catfish cultivation will produce wastewater with a high content of organic matter from feces and uneaten feed. If the wastewater is discharged directly into common waters, it will disturb the aquatic ecosystem. So, it is necessary to treat wastewater before it is discharged into common waters. The purpose of this study is to determine the difference in the percentage of experimental media using wiker bamboo lid towards the organic matter in the wastewater of catfish farming. The research was conducted from September to October 2019 at the Laboratorium Hidrobiologi Divisi Sumberdaya Ikan, Universitas Brawijaya. The research method used was an experimental method with a 2-factor factorial completely randomized design. The first factor was the percentage of bamboo wicker lid (25%, 50%, 75%, 100% and 0% (control)). The second factor was the observation time (12, 36, 48, 60 and 72 hour). The results indicated that organic matter could decrease to 82.19% (73.31 mg / L to 13.06 mg / L) in the 75% lid treatment at 48 hours. The results of water quality measurements except carbondioxide are in accordance with water quality standards. The presence of bamboo cover can reduce organic matter in wastewater. However, it needs treatment for carbondioxide.
