Kerusakan Insang dan Pertumbuhan Udang Windu (Penaeus Monodon Fab.) di Tambak Keputih Surabaya yang Tercemar Logam Timbal (Pb)
Abstract: Keputih Surabaya is
a coastal area that most of people livelihood as farmers. Tiger shrimp (Penaeus
monodon Fab.) is one of the organisms are cultivated in fishponds Keputih
Surabaya. That fishponds has been known contaminated by lead (Pb). One of the
lead (Pb) entry mechanisms into the shrimp is through the gills. Therefore,
needs to be seen shrimp gill damage caused by the lead (Pb) metal. This
research conduct to determine levels of lead (Pb) in water, sediment and tiger
shrimp, gill damage and the growth of shrimp in fishponds that is contaminated
by lead (Pb). This research is the observation that take samples from 3
stations. Each station is taken water, sediment, and tiger shrimp (Penaeus
monodon Fab.). To determine the levels of lead (Pb) is used Analysis Atomic
Absorption (AAS) method at Balai Besar Teknik Kesehatan Lingkungan dan
Pemberantasan Penyakit Menular (BTKL) Surabaya Laboratory. Tiger shrimp gill
preparations made by the method of preservation microtehnique
Haematoxylin-Eosin staining in the Pathology Laboratory Airlangga University,
Surabaya. The data that is obtained were analyzed descriptively and compared
with the quality standards based on Government Regulation no. 82 of 2001 about
Water Quality and Water Pollution Control. The results showed levels of Pb in
the water 0,1903 ppm and 5,146 ppm sediment, those results exceed the quality
standards (> 0,03 ppm), and 6,6104 ppm in tiger shrimp exceeds the quality
standard (> 0,5 ppm). Gill damage exposure lead (Pb) is necrosis, congestion
and rupture secondary filaments. Tiger shrimp growth is inhibited, because
adult shrimp reaches length is 33 cm and weight 20-35 grams. Keputih Surabaya
fishpond water quality except temperature and pH are not in accordance with
requirements of growth and development of the shrimp.
