STRUKTUR MIKROSKOPIS HATI IKAN SEURUKAN (OSTEOCHILUS VITTATUS) DARI SUNGAI KRUENG SABEE KABUPATEN ACEH JAYA YANG TERCEMAR LIMBAH PENGGILINGAN BIJIH EMAS
ABSTRACT: This research is to
observe the Seurukan (Osteochilus vittatus) fish liver microscopic structure in
Krueng Sabee river, Aceh Jaya Regency. Fish and river water samples were taken
from May to June 2015. Histological techniques and research parameters was
conducted in FMIPA Microtechnic Laboratory, Syiah Kuala University, while river
water and Seurukan fish mercury level was analyzed in Balai Riset dan Standarisasi
Industri, Banda Aceh. Completely Randomized Design was applied of the research
with three treatments. The treatments were location of fish sample taken
through the lenght of Krueng Sabee river that were Panggong village (location
I), Paya Seumantok village (location II), and Mon Mata village (location III).
Each treatment consisted of six repetition (six fishes). Microscopic structure
of Seurukan fish liver was observed with paraffin method histological
techniques. The parameters calculated were amount of fish hepatocytes with
degeneration and necrose. The data was analyzed using Analysis of Variance
followed by Tukey's test. Mercury level of river water in location I is
0,0001047 ppm, location II and III are <0,00001 ppm, meanwhile range of Seurukan
fish mercury level in location I are 0,0002333-0,061 ppm, <0,0019-0,3478 ppm
(location II), and 0,062-0,141 ppm (location III). The results showed that
amount of hepatocytes degeneration are 0,27±0,04 in location I, 0,28±0,03 in
location II, and 0,27±0,03 in location III, meanwhile the hepatocytes necrose
were in location I (0,69±0,03) and location II (0,67±0,03) higher than location
III (0,62±0,04). The sampling location in Kreung Sabee river was significant
difference to hepatocytes necrose of Seurukan fish but not significant to
hepatocytes degeneration.
