Industrial activity is commonly a potential source of water pollution in urban development area. Industries have to treat their wastewater prior to effluent discharging to the river or nearest water body. Compliance to effluent standard is a monitoring system to protect any adverse impact to the water body. Prokasih is also applied to maintain the quality of the river. This study is aimed to analyze acute toxicity (LC50), besides some parameters listed in effluent standard, on 6 types of industrial effluents in Cimahi (West Java area). The acute toxicity test was carried using Daphnia sp and Moina sp. The study showed that effluent from pharmacy industry was the most toxic (LC50 of 1.17 % effluent) followed by paints (2.41% effluent), textiles (3.73% effluent) and leather tanning (6.97% effluent). Toxicity testing using Daphnia sp demonstrated to be more sensitive than those by Moina sp. This toxicity test results could be used as a potential parameter in evaluating the effectiveness of wastewater treatment plants as it also provided a whole response of the test organisms to any effluent substances.
