Abstract

Limbah cair industri tahu akan berpengaruh terhadap badan air apabila langsung dibuang tanpa dilakukan pengelolaan terlebih dahulu, dan menyebabkan masalah terhadap kualitas air dan kehidupan biota akuatik. Penelitian ini bertujuan untuk menguji dampak konsentrasi limbah cair industri tahu terhadap kualitas air, pola renang dan tingkah laku ikan. Penelitian dilakukan dengan uji coba di Laboratorium menggunakan akuarium dan dianalisis secara deskriptif. Adapun perlakuan yang dicobakan adalah limbah cair tahu dengan konsentrasi 0%; 0,4%; 0,6%; 0,8%; 1,0% dan 1,2% dari volume air 10 liter. Setiap akuarium diisi ikan sebanyak 24 ekor dengan ukuran 4-5 cm. Metode Pengamatan dilakukan selama 96 jam. Hasil pengukuran kualitas air pH, DO, CO2, COD, TSS dan H2S melebihi standar baku mutu, sedangkan suhu, BOD5 dan amoniak masih dibawah standar baku mutu. Tingkah laku ikan bergerak menghindari limbah, perilaku bergerombol sedangkan pola renang ikan berenang dipermukaan, berenang tidak beraturan, pola renang berubah dengan posisi berdiri. Konsentrasi limbah cair tahu 0,4%; 0,6%; 8%; 1,0% dan 1,2% berpengaruh terhadap pola renang dan tingkah laku ikan.

Abstract

The purpose of this research were to measure the increasing of unionized ammonia during start-up period of biofloc system for growing Nile Tilapia and to figure out its effect on histopathological changes. There was only one treatment that designed with three replication, which was 40 liters of water that contained eight fishes of each weighed 22.. The biofloc system was treated with C/N ration 12:1. Total Ammonia Nitrogen, pH and temperature were measured daily as long as 14 days. the tissue of gill, liver and kidney were cut off at the end of the experiment for histopathological examination. The result of the experiment showed that the peak of unionized ammonia concentration achieved 0.34±0.05 mg/l at 10th day. Then, decreased rapidly to 0.003±0.0009 mg/l at 14th day. The gill, liver, and kidney had regressive changes as physiologic sub lethal response of unionized ammonia expose. Keywords : Biofloc, unionized ammonia, Nile Tilapia, histopatholocal

Abstract

The objectives of this study were to determine the heavy metals contents (Cd, Pb, Cu and Zn) in the body of some freshwater fish and to examine the histopathological changes of some organs.  The fish were obtained from Payau River located in Anggana, Kutai Kartanegara District, East Kalimantan, Indonesia.  There were four (4) species examined namely: Glass Fish (Chanda sp), Croaker (Micropogenias undulatus), Lais (Kryptopterus cryptopterus), and spotted catfish (Arius maculatus).  Lead (Pb), Cadmium (Cd), Copper (Cu), and Zinc (Zn) were being analysed in the gills, livers, and the muscles of the fish.  The results showed that Pb and Cd were still low and fulfilled the the quality standard based on Indonesian National Standards Agency (INSA, 2009) and Directorate of Drug and Food Control No. 03725/B/SK/VII/89.  Cadmium concentration in the fish organ was < 0.003 mg/kg (Max. limit of Quality standard is 0.1 mg/kg) and Pb concentration was <0.002 mg/kg (Quality standard is 0.3 mg/kg).  Yet, Cu and Zn concentrations were exceeded the Quality standard as the levels were 2.63-2.93 mg/kg and 60.23 -65.55 mg/kg., respectively.  Based on Histopathological analysis of the gills, livers and muscles, the fish experienced edema, hyperplasia, vacuolar degenerative, necrosis and hemorrhagic ..
