Status Limnologis Situ Cilala Mengacu pada Kondisi Parameter Fisika, Kimia, dan Biologi Perairan
Abstract: The purpose of this
research was to study the limnological status of Cilala reservoir, based on
physical, chemical, and biological parameters. The observation comprised some
morphometric of surface and vertical dimension, water quality measurements,
plankton community structure, and primary productivity. Based on some
morphometric condition, Cilala reservoir has a high potention of biological
productivity, but the area of lake begins narrowing. The physical and chemical
characteristic showed that Cilala reservoir was still in good condition. The
condition of Total Suspended Solid (TSS) at inlet and the water debit of outlet
showed that the waters has a relatively high potention of sedimentation that
lead to a shallowing condition. There were found 95 genus of phytoplankton from
seven classes (Bacillariophyceae, Chlorophyceae, Cyanophyceae, Chrysophyceae,
Euglenophyceae, Pyrrophyceae, and Xanthophyceae). It was also found four major
groups of zooplankton, i.e. Rotifera, Copepoda, Cladocera, and Protozoa.
Although the primary productivity was relatively low, based on orthophosphate,
chlorophyll-a, and Nygaard Index, the water was in mesotrophic-eutrophic
status. As a whole, Cilala reservoir was still appropriate for fisheries
activities.
