UJI TOKSISITAS AKUT INSEKTISIDA DIAZINON DAN KLORPIRIFOS TERHADAP BIOTA UJI IKAN GUPPY POECILIA STRATIOTES DAN TUMBUHAN KAYU APU PISTIA STRATIOTES

ABSTRAK

Penggunaan pestisida di bidang pertanian dalam pengendalian dan pemberantasan organisme pengganggu tanaman telah dilakukan secara meluas oleh masyarakat. Insektisida berbahan aktif diazinon 600 gL dan klorpirifos 200 gL merupakan insektisida golongan organofosfat yang banyak digunakan dalam bidang pertanian dan berpotensi sebagai zat pencemar perairan. Penelitian ini akan mengkaji nilai kematian biota uji ikan guppy Poecilia reticulata dan tumbuhan kayu apu Pistia stratiotes akibat pemajanan insektisida diazinon dan klorpirifos selama 96 jam 4 hari. Variasi konsentrasi masingmasing insektisida yang dipaparkan pada tahap range finding test terhadap ikan guppy sebesar 0 kontrol 001 mgL 01 mgL 1 mgL 10 mgL dan 100 mgL. Hasil dari tahap ini dipersempit lagi untuk digunakan pada tahap acute toxicity test. Penentuan nilai LC-50 didapat dari pengolahan data menggunakan metode Lichfield Wilcoxon. Hasil yag diperoleh berdasarkan penelitian untuk biota uji ikan guppy dengan toksikan diazinon diperoleh nilai LC-50 96 jam ikan Guppy 172 mgL. Untuk insektisida jenis klorpirifos diperoleh LC-50 96 jam 074 mgL. Pada tumbuhan kayu apu dengan insektisida diazinon sebesar 554 mgL dan tumbuhan kayu apu insektisida klorpirifos sebesar 424 mgL.


ABSTRACT

The use of pesticides in agriculture in the control and eradication of plant pest organisms has been performed widely by the public. Active-based insecticide diazinon 600 gL and 200 gL chlorpyrifos is an insecticide of organofosfat that is widely used in the fields of agriculture and potentially as the astringent waters of polluters.This research will examine the value death life test of guppy Poecilia reticulata and plant Pistia Pistia stratiotes due to exposure to insecticides diazinon and chlorpyrifos for 96 hours 4 days. Variation of the concentration of each of the insecticides that are displayed in the range finding test to the guppy fish of 0 control 0.01 mgL 0.1 mgL 1 mgL 10 mgL and 100 mgl. results from this stage narrowed again for use in the acute toxicity test. The determination of the value of LC-50 gained from data processing method using Wilcoxon Lichfield. The results based on research derived yag for biota guppy fish with toksikan test diazinon retrieved the value of LC 50 96 hours-Guppy fish 172 mgl. To insecticides chlorpyrifos obtained types of LC 50 96 hours 074 mgl. in plants with insecticides diazinon Pistia of 554 mgL and the insecticides chlorpyrifos Pistia plants of 424 mgL.
