Item Penggunaan Metode Indeks Pencemaran Dan Nsf-Wqi Untuk Menentukan Kualitas Air Sungai Batang Ampalu(wahyu sari yeni, 2019-01-09) Putri, Auwilla; Dewata, IndangThe study was conducted on the Ampalu River to determine river water quality using pollution index (PI) and NSF-WQI methods. The river is one of the small rivers in the city of Padang and is used as drinking water sources, and for the purpose of fisheries, agriculture and water recreation so that the quality needs to be analyzed. The data used is monitoring data of Environmental Protection Agency of Padang Laboratory in 2017 at 2 stations by analyzing 13 parameters, namely temperature, turbidity, TSS, TDS, pH, DO, BOD, NH3-N, NO2-N, NO3-N, total phosphate, fecal coliform and COD. The analysis results showed that there is no influence of the season for the status of water quality of Ampalu River in 2017. The upstream part of the river is in lightly polluted condition with a PI value of 2.07 while the downstream is in a moderately polluted condition with an IP value of 5.63. The analysis results of water quality index show that in the dry season the quality of river water is in the medium category with NSF-WQI values at the upstream and 50.21 at the downstream. In the rainy season, the water quality index of the upper reaches of the Ampalu River is in the medium category with NSF-WQI values of 54.31 and in the downstream in bad conditions with NSF-WQI values of 48.94. It is hoped that the results of this research can be used to improve the quality of Ampalu River so that the river can be utilized in accordance with its purposes.
