ABSTRAKPenggunaan insektisida klorpirifos mencapai 99,8% oleh petani di Provinsi Sumatera Barat. Fungsi utama klorpirifos dalam pertanian adalah melindungi tanaman jagung, kapas dan buah-buahan terhadap hama serangga. Klorpirifos yang telah disemprotkan ke tanaman, berpotensi terbilas oleh air dan mengalir ke wilayah perairan sehingga dapat mencemari ekosistem perairan. Salah satu biota perairan adalah ikan. Tak terkecuali kegiatan pertanian dan perkebunan di Kawasan Danau Kembar (Danau Di Ateh dan Danau Di Bawah), Sumatera Barat. Klorpirifos yang biasa digunakan para petani di kawasan ini adalah merk Dursban. Konsentrasi klorpirifos terdeteksi sebesar 0,007 mg/L di perairan danau tempat melakukan budidaya ikan. Jenis ikan yang biasa dibudidayakan di Danau Kembar adalah Ikan Mas (Cyprinus carpio L) dan Ikan Nila (Oreochromis niloticus). Penelitian ini bertujuan untuk melakukan uji toksisitas akut dan menganalisis nilai LC50-96h insektisida klorpirifos dengan menggunakan hewan uji dua jenis ikan budidaya tersebut pada skala laboratorium. Penentuan nilai LC50-96h mengacu pada Metode USEPA. Jumlah hewan uji untuk masing-masing jenis ikan adalah 240 ekor dengan umur ± 1 bulan. Penelitian dilakukan dengan dua kali pengulangan dengan metode static test. Uji toksisitas akut ini meliputi uji pendahuluan dan uji dasar. Pengujian berlangsung dalam kondisi fisik air sesuai batas yang diizinkan untuk pemeliharaan ikan budidaya yaitu pH 6 – 9, DO minimal 3 mg/L dan suhu 25 – 30 oC. Hasil penelitian uji toksisitas akut ini diperoleh nilai LC50-96h dengan menggunakan Metode Probit sebesar 0,03 mg/L (ikan mas) dan 0,08 mg/L (ikan nila). Berdasarkan nilai LC50-96h yang diperoleh, klorpirifos termasuk kategori sangat toksik, sehingga monitoring terhadap penggunaan insektisida ini sangat diperlukan.Kata kunci: Danau Kembar, Ikan Mas, Ikan Nila, Klorpirifos, LC50-96h, Toksisitas Akut.ABSTRACTThe use of chlorpyrifos insecticide reached 99.8% by farmers in West Sumatera Province. The main function of chlorpyrifos in agriculture is to protect corn, cotton and fruit trees against insect pests. Chlorpyrifos that have been sprayed into plants, potentially flushed by water and flowed into the water body so as to pollute the aquatic ecosystems. One of the aquatic biota is the fish. No exception agricultural and plantation activities in the area of Twin Lakes (Di Ateh Lake and Di Bawah Lake), West Sumatra. Chlorpyrifos commonly used by farmers in this region is the brand Dursban. Measurements of chlorpyrifos concentration was 0.007 mg/L in the waters of the lake where fish cultivation. Types of fish commonly cultivated in Twin Lakes are Common carp (Cyprinus carpio L) and Nile tilapia (Oreochromis niloticus). This study aims to perform the acute toxicity test and analyze the value of LC50-96h chlorpyrifos insecticide by using the test animals of two species of fish cultivation on the laboratory scale. The determination of the LC50-96h value refers to the USEPA Method. The number of test animals for each species of fish is 240 with an age of ± 1 month. The study was conducted with two repetitions using static test method. These acute toxicity tests include preliminary and baseline tests. The test takes place in the physical condition of the water according to the permitted limits for the maintenance of the aquaculture fish ie pH 6 - 9, DO at least 3 mg/L and temperature 25 - 30oC. The results of this acute toxicity test obtained LC50-96h value using Probit Method of 0.03 mg/L (carp) and 0.08 mg/L (tilapia). Based on the value of LC50-96h obtained, chlorpyrifos is a highly toxic category, so monitoring of the use of insecticides is important.Keywords: Twin Lakes, Common carp, Nile tilapia, Chlorpyrifos, LC50-96h, Acute ToxicityCitation: Ihsan, T., Edwin, T., Husni, N., dan Rukmana, W.D.

Abstract: Toxicity Test Of Acute Industrial Waste Water On Tilapia Fish (Oreochromis Niloticus). The sasirangan industrial liquid wastes containing high ammonia and high pH when discharged into the receiving water body without treatment will result in changes in water quality and even the death of aquatic biota so that an acute toxicity test is necessary. This study aims to determine the value of LC50 from waste sasirangan against tilapiaI. This research used the experimental method of Post Control Only Control Group Design design. Samples taken as much as 100 liters of waste in one industry sasirangan existing in the city of Banjarmasin. Concentrations of the sasirangan waste solution to be used in the acute toxicity test are: 4, 8, 12, 16 and 20%. Parameters studied include ammonia, DO, pH, and temperature. To determine the value of LC50 using probit analysis. The results showed that LC50 for exposure time 24, 48, 72 and 96 hours were 14.73%, 10.21%, 8.26%, and 7.35%, respectively. The results of the analysis show that pH and ammonia content of industrial effluent sasirangan affect the death of tilapia fish. This research is hoped that the sasirangan industry does not dispose of its waste directly to the water body but needs to process it first. For further research it can complement the untested parameters such as BOD, COD, and TSS that affect fish survival.

In recent years many waterways in Slovenia have been subjected to an increased loading with pesticides due to intensification of agriculture. The most widely used herbicides are atrazine and alachlor and they were detected in some rivers and even in ground water. Therefore the effects of atrazine and alachlor on selfpurification processes were investigated. The basic selfpurification processes studied were biodegradation of organic substances and photosynthesis and growth of algae. The inhibiting effect of pesticides on the process of biodegradation of organic pollutants was evaluated by the use of laboratory river model and mathematical modelling. The harmful impacts of pesticides on aquatic autotrophic organisms were assessed by measurement of net assimilation inhibition (24-h acute toxicity test) as well as growth inhibition - chlorophyll- a content (72-h chronic toxicity test) of algae Scenedesmus subspicatus. The results obtained demonstrate that atrazine and alachlor in concentrations found in our rivers have practically no effect on biodegrading heterotrophic organisms, while their adverse effect on algae is quite considerable.

This study aimed to determine the lethal concentration (LC50) of Terminalia catappa leaves extract on three cyprinid species; carp (Cyprinus carpio), goldfish (Carassius auratus) and tiger barb (Puntigrus tetrazona) through the acute toxicity test. The leaves of T. catappa were extracted with methanol and prepared in various immersion concentrations (40, 80, 100, 150, 200, 250, 300, and 350 mg/L). These extracts were immersed in the aquarium and left for 24 h before performing the acute toxicity test. The water quality was also analyzed before and after adding the extract immersions into the aquarium. The acute toxicity test conducted for 96 h with 10 fishes of each cyprinid species (4.0-6.0 cm length) in 30 L water capacity aquarium. The mortality of each cyprinid species was recorded at 24 h time interval and LC50 of the extracts throughout 96 hours was determined through the probit analysis application. Specifically, the LC50 of T. catappa leaves extract were 349.89, 338.65 and 318.48 mg/L exhibited for carp, goldfish and tiger barb, respectively. A high concentration range of any plant-based extract has the potential to become toxic to particular fishes. Thus, it is an effort from this study to identify the safety margin of T. catappa leaves extract before its therapeutic values can be further manipulated and elucidated in aquaculture research.

Landfill Leachates is one of the pollutants containing high organic matter and heavy metal which can cause toxic pollution to water due to less than optimal leachate processing. This study aims to introduce fine bubbles treatment to the leachate processing technology at the waste treatment facility at Sarimukti, West Java Indonesia. The toxicity test was conducted in the acute toxicity test and test for D. magna. The acute toxicity test was carried out using a static biological test according to APHA standards (1995). The LC50-48 hours ware calculates using the Finney Probit Analysis Software. The results showed that the effectiveness of Sarimukti TPA leachate treatment was 97.5% DO, 71% BOD, 86% TDS, and 74.8% turbidity. The XRF spectra on the leachate after fine bubble found a recovery of heavy metal elements such as Cr, Mn, Fe, Zn, Cu, Pb, As, and Sn. Based on the Minister of Environment and Forestry Regulation, the effectiveness of leachate processing has reached the safe standard limit for pH, mercury, cadmium parameters. The acute toxicity of leachate before and after treatment fine bubble was 14.516 ppm and 11.178 ppm. The acute toxicity of leachate is considered almost non-toxic.
