Argosari Village is one of the villages that has cattle farms in Malang Regency. This research was conducted in one of the houses in Argosari Village and has 6 (six) of cows. In one day, each cow produces 100-150 liters of liquid waste. However, the liquid waste is immediately discharged into the drainage channel because there is no effort to process wastewater. On the results of laboratory tests, samples of wastewater, BOD, COD, TSS, NH3-N and pH in wastewater were respectively 4488 mg/L, 11000 mg/L, 850,5 mg/L, 479,3 mg/L, 8,5 mg/L. Based on the Regulation of the Minister of Environment Number 11 of 2009, the liquid waste has not met the quality standard. Wastewater Treatment Plant (WWTP) is needed to save reserves on cattle wastewater. The suitable installation in this condition is an initial settling basin, aerobic biofilter basin and a final settling basin. Aerobic biofilter is used so that liquid waste can be used biologically by using the media of honeycomb biofilter to grow and breed microorganisms. After processing the WWTP, there is a decrease in effluent, so WWTP can produce effluent BOD of 80,78 mg/L, COD = 198 mg/L, TSS = 5,10 mg/L, NH3-N = 23,9 mg/L and pH = 8,5.

Discharge data is usually less available than rainfall data, so it is necessary to find a relationship between river flows that are applied in the period available rainfall data in a watershed area. The purpose of this study is to determine the suitability of the method based on the analysis of data validation between the observed discharge and the model discharge. The method is done by modeling the discharge based on rainfall with the Artificial Neural Network (ANN) MATLAB R2014b program. The Upper Brantas Watershed is used as a case study because it often has runoff problems. Validation of the ANN method was tested with Root Mean Square Error (RMSE), Nash-Sutcliffe Efficiency (NSE), Correlation Coefficient (R) and Relative Error (KR). From the results of calibration using the ANN Model, the best data is found in the five years data of epoch 500. Verification results based on the value of R have a relatively good relationship between observation discharges with model discharges. The validation results show the validity in a year data of epoch 500.
