Environmental assessment of polyculture farming practice based on macrobenthic assemblages: a study case at coastal area of Kaliwungu, Kendal (Central Java, Indonesia)
The purpose of this study was to determine environmental quality parameters using number
of species, diversity and similarity of macrobenthic communities. This study was conducted
at two locations, the Location I was a polyculture farming area, farming milkfish (Chanos
Chanos) and black tiger shrimp (Penaeus monodon) and seaweed Gracilaria sp. in the
coastal area of Mororejo, Kendal District, Central Java. Location II was the coastal area of
PT. Plywood Indonesia, which is located adjacent to industrial activities as well as directly
affected the tide. Systematic random sampling was employed, measuring physicalchemical
parameters of water and sediment. Samples of macrobenthos were taken from
the sediment. Data was analysed using diversity and evenness indices approach. Samples
of macrobenthos were taken from the sediment using Eckman grab, then was analysed
using diversity and evenness indices approach. Results showed that the Location I was
dominated by Cerithidea cingulata and Terebralia sulcata (Potamididae), Minima batillaria
(Batillaridae). The Location II was dominated by Cirratulus sp., Cirriformia sp. and
Aphelochaeta (Cirratulidae) and Prionospio sp. (Spionidae), which are considered as
indicators of disturbed area. This results implied that the use of area for both polyculture
and industrial activities may lead to environmental disturbance, thus environmental coastal
management need to be applied in regular basis, both temporally and spatially
