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.

西爪哇省梳邦布拉纳干河上游大肠菌群和铜 (Cu) 的评价

本研究旨在通过评估大肠菌群和重金属铜的存在与否来确定水的质量。水质评价在布拉纳坎河上游进行,考虑到上游由于人类活动而受到更多污染物的影响,因此很脆弱。水样采集自上游三个站点。使用原子吸收光谱 (AAS) 分析水中的铜。同样,使用最可能数(MPN)方法对大肠菌群进行计数。结果表明,大肠菌群的范围为0.43-110 MPN/ml,平均值为36.9 MPN/ml,超过了2001年第82号政府规定的I类水质标准范围。同时,平均重金属Cu的值为0.04 mg/L,
