Penilaian Kualitas Air Dengan Indeks Nsf-Wqi Di Danau Bunter Desa Pangkalan Baru Kecamatan Siak Hulu Kabupaten Kampar Riau
Several activities in the Bunter Lake contributed the input of organic and anorganic
matter that affects the water quality, especially nutrient concentration in
waters. A research aims to understand the trophic state of the Bunter Lake based
on NSF-WQI has been conducted in August – September 2019. There were three
stations namely Station I (inlet area), Station II (around the plantation area) and
Station III (outlet area). Sampling were conducted 3 times, once/week. Water
quality parameters measured were temperature, turbidity, NTU, TSS, pH,
dissolved oxygen, BOD5, nitrate and total phospate. The water quality values are
as follows: temperature: 28.7 – 30 oC, turbidity: 7.83 – 10.08 NTU, TSS: 19.7 –
28.7 mg/L, pH: 5, dissolved oxygen: 4.27 – 4.56 mg/L, BOD5: 8.14 – 8.72 mg/L,
nitrate: 0.24 – 0.26 mg/L, total phospate: 1.19 – 1.62 mg/L and NSF-WQI: 51.38
– 52.68. Based on NSF-WQI value, water quality of the Bunter Lake can be
categorized as moderate to mesotrophic.
