Abstract

This study aims to determine the quality of water by evaluating the presence or absence of coliform bacteria and heavy metal Cu as well. The water quality evaluation was conducted in the upstream of Blanakan river, considering that the upstream is vulnerable since it receives more pollutants due to human activity. The water samples were collected from three stations in upstream. The Cu in water was analyzed using Atomic Absorption Spectroscopy (AAS). Likewise, the coliform bacteria were counted by using Most probably Number (MPN) method. The results showed that the range of coliform bacteria was 0.43 - 110 MPN/ml and the average was 36.9 MPN/ml, which is exceeding the range of water quality standard class I according to Government Regulation No.82 of 2001. Meanwhile, the average value of heavy metals Cu is 0.04 mg/L, which is also exceeding the range of water quality standard class I according to Government Regulation No.82 of 2001. Hence, the upstream of Blanakan river has been contaminated by coliform and Cu.
