Following regulation, Leachate Treatment Facility (LTF) wasbuilt in Piyungan landfill to reduce its negative impact to the environment. The effluent from this LTF is regularly monitored to check its compliancewith government standard. However, the standard does not fully addressthe effect of combined components in a particular wastewater on livingorganism. Hence, it is necessary to conduct toxicity test to fill this gap. This study was aimed to analyze the acute toxicity status of leachate preand post-treatment from leachate treatment facility of Piyungan Landfill. The method used for the test is Whole Effluent Toxicity (WET) by usingCyprinus carpio as test organism. Acute toxicity test was performed bynon-renewal static method for 96 hours. The result showed that LC50 ofCyprinus carpio are 1,633% and 8,740% for influent and effluent of LTFrespectively. The LTF has reduced the Toxic Unit acute (TUa) ofpretreated leachate with 61,246 in the influent to be 11,442 in the effluent. However, even in the effluent, the leachate is still classified as High AcuteToxicity. It is recommended to improve the performance of LTF to furtherreduce leachate toxicity level to be No Acute Toxicity.
