Abstract
Water used from cattle farming operations that is not properly managed and discharged directly into the environment caused unpleasant odors and increase the risk of contamination of surrounding water bodies. The purpose of this research was to determine an effective management system in solving odor problems and the risk of contamination of water bodies. The method in this research includes the design of a management system and laboratory-scale processing experiments involving the oxidation pond as the processing unit. The cattle farm liquid waste management system consists of 3 stages, namely pretreatment, primary treatment and secondary treatment. Pre-treatment is carried out from the time the waste is generated to the drainage at the cage location. The primary treatment consists of filtering large particles that have the potential to clog and deposition of suspended solids, which in this study was carried out by the initial settling tank processing unit which also functions as a reservoir. Secondary treatment is the core of farm wastewater treatment where there is an oxidation pond treatment unit and a final settling basin which also acts as a final reservoir before it is discharged into the drainage around the farm to the water body. Wastewater is treated in the oxidation pond with a variation of the injected oxygen discharge of 6 L / minute, 8 L / minute, and 11 L / minute with residence time during the calculation time according to EPA / 600 / R-11/008 of 2011 (respectively 0.256 days, 0.1356 days, 0.1096 days), 3 days, 7 days, and 14 days. The aerobic process in the oxidation pond is controlled using the oxidation reduction potential (ORP) value. The parameters observed were Biochemical Oxygen Demand (BOD) and Total Ammonia (NH3-N). Where the test results after the study showed that the average BOD level had met the quality standard. With the highest final BOD level was 152 mg / L and the lowest was 98 mg / L. Meanwhile, the highest total ammonia levels after research were 0.0088 mg / L and the lowest was 0.00032 mg / L. The physical condition of wastewater after processing is yellowish with low turbidity and has no smell. Keywords: liquid waste, cattle farming, waste management, oxidation pond
