Abstract

Insektisida sipermetrin dan lamda sihalotrin merupakan pestisida golongan piretroid yang banyak digunakan petani untuk melindungi hasil produksi pertanian dari berbagai macam hama pengganggu. Namun pemakaian yang kian meningkat dengan penggunaan yang tidak tepat akan menimbulkan potensi pencemaran pada lingkungan perairan. Maka dari itu, kiranya perlu dilakukan uji toksisitas untuk mengetahui batas toksisitas dan konsentrasi aman, sehingga kerugian untuk biota air dapat diminimalisir kedepannya. Pada penelitian ini akan dilakukan uji toksisitas akut terhadap insektisida sipermetrin dan lamda sihalotrin yang dilakukan selama 96 jam (4 hari) pada Ikan guppy (Poecilia reticulata) dan Kayu Apu (Pistia Stratiotes). Variasi kosentrasi pada uji toksisitas akut diperoleh dari Range Finding Test dengan kosentrasi 0 mg/l (kontrol) ; 0,01 mg/l ; 0,1 mg/l ; 1 mg/l ; 10mg/l; 100 mg/l. Kemudian, dilakukan uji acute toxicity dengan mempersempit rentang variasi volume air pengencer/volume toksikan. Digunakan pengolahan data dengan metode Lithfield- Wilcoxon selama LC 50-96jam Berdasarkan penelitian, diperoleh nilai LC50 insektisida sipermetrin dan lamda sihalotrin berturut-turut terhadap ikan guppy sebesar 0,4393 mg/L dan 0,07118 mg/L. Sedangkan nilai LC50 insektisida sipermetrin dan lamda sihalotrin berturut-turut terhadap tumbuha kayu apu sebesar 48,658 mg/L dan 5,0237 mg/L. ============================================================================================================ Chypermetrin insecticides and lambda cyhalothrin are the pyrethroid class of pesticides widely used by farmers to protect agricultural production from a variety of pests. However, with the increasing of inappropriate use will lead to potential contamination in the aquatic environment. Therefore, it is necessary to determine the toxicity test to know the toxicity limit and safe concentration, so the damage to aquatic biota can be minimized in the future. In this study, the acute toxicity tests will be done towards sipermetrin insecticides and lambda cyhalothrin conducted for 96 hours (4 days) in the guppy fish (Poecilia reticulata) and water lettuce (Pistia stratiotes). Concentration variation in acute toxicity tests obtained from the range finding test with a concentration of 0 mg /L (control); 0.01 mg /L ; 0.1 mg /L ; 1 mg /L ; 10mg /L; 100 mg /L. Then, the acute toxicity test with a narrow range of variation of dilution water volume / toxicant volume is done. The data processing uses Lithfield-Wilcoxon method for 50-96 hours LC. Based on the study, LC50 values of chypermetrin insecticides and lambda cyhalothrin are obtained consecutively against guppies at 0.4393 mg /L and 0.07118 mg /L. While the LC50 values of chypermetrin insecticides and lambda cyhalothrin consecutively against shell flower are 48,658 mg /L and 5.0237 mg /L
