Abstract

ABSTRACTEcological aspect (morphometry, a complexity of community structure, trophic state, and carrying capacity) are one of basic information to build comprehensive management concept of aquatic ecosystem, as Lake Cilala.  The concept was addressed to develop ornamental fish floating cage and natural fishery activity.  Lake Cilala is a longwise shape small lake with maximum length, average width, and average depth as 1141 m, 161 m, 2.67 m respectively.  Lake Cilala has various genera of phytoplankton and zooplankton, 8 genera of benthos, 5 genera of aquatic plants, and 12 fish species including planktivore, herbivore, and carnivore fishes.  Those organisms established food chains, by grazing and detritus food chain.  The trophic state of Lake Cilala was categorized as middle to heavy eutrophic level by Trophic State Index (TSI).  The carrying capacity analysis of Lake Cilala is 130 tons/year. It is resulted a possibility to increase ornamental fish floating cage to 165 units from 300 existed units. Furthermore, the carrying capacity for natural fish was reached 3.77 tons/year. Keywords: carrying capacity, food chain, lake fisheries, small lake management, trophic state

Abstract

ABSTRACT Wastewater from laboratory glassware washing activities contains organic materials. Decomposing bacteria could increase the biomass by utilizing organic matter as a source of carbon. This research was aimed to describe the influence of commercial probiotic application in reducing organic matter content of Proling laboratory wastewater. The research was conducted from February to July 2016 in Aquatic Microbiology Laboratory. The experiment consists of several treatments, those were wastewater (L), wastewater+molase (LM), and wastewater+molase+bacteria from commercial probiotic (LMB). Major parameters observed were COD and bacteria abundance. The results showed that there was significant response difference between molasses and without molasses treatment. Based on COD, the most influenced treatment in decreasing organic matter were LM and LMB. These treatments could decrease COD up to 97% and 91%. Furthermore, the abundance of bacteria in molasses treatment was higher than without molasses. Based on this study, the most effective treatment in reducing organic matter was LMB.  Keywords: bacteria, laboratory wastewater, molasses, organic matter
