Abstract

ABSTRACTThe development of floating net aquaculture in Jatiluhur reservoir that reach up 21000 to 26 717 plot have been resulted in eutrophication that interfere of water treatmen raw water, tourism and water sports, so the reduction and redeployment zones floating net in the reservoir needs to be done. The purpose of this study looking for zone of floating net aquaculture in Jatiluhur reservoir. The zone is obtained from the optimization by maximizing the density plots floating net per segment in alternate zones with constraints status trophic allowed in the area of water treatment raw water in take, tourism and water sports in the downstream Jatiluhur reservoir through simulation of the chlorophyll-a concentration distribution from the 2 -dimensional layered eutrophication model for scenarios increase every 10 plots floating net in segments of alternative zones 1, 2, 3 in the downstream reservoirs and alternate zone 4 in the middle of the reservoir. The results of the eutrophication 2-dimensional layered model calculation been obtained segment length and width of 100 m. The optimization results show, the carriying capacity of water due to zoning plots Jatiluhur reservoir floating net per segment in the middle of the reservoir is greater than the downstream of the reservoir, and to get water Jatiluhur reservoir in oligotrophic status that does not interfere with other uses of the reservoir water, and to get water Jatiluhur reservoir in oligotrophic status that does not interfere with other uses of the reservoir water, the highest density of a plot floating net per segment is the alternative zone 4 of 10 plot floating net per segment or 4,420 plot floating net. For the the aquaculture fish in floating net in the area are currently recommended to be moved to alternative zone 4 which is located in the central part Jatiluhur reservoir.Keywords: floating net plot zone, Jatiluhur reservoir, optimalitation, 2-dimensional layered eutrophication

Abstract

ABSTRACTStudy on The Relationship Between Phytoplankton and Current Velocities due to Operationof Jatiluhur Reservoir. High abundance of phytoplankton may create oxygen depletionwithin water column, in which may also lead as a threat to the fisheries activities of floatingcage in the Jatiluhur reservoir. In addition, phytoplankton may also clog the filter within watertreatment plant that is currently using the water from Jatiluhur reservoir. The research objectivewas investigate effects of changing water current velocity to the abundance of phytoplanktonin the Jatiluhur reservoir. Phytoplankton, measured as chlorophyll-a, were sampled at 10 differentsampling points of 0, 4, 8 and 10 m depth. While current water velocities were calculated usingtwo-dimensional multilayer equation. The equation will calculate x and y axis current velocitieswithin different depth of the reservoir. Result shows that in the area in which the currentvelocities higher than 15 cm/s less phytoplankton would be found. These velocities found ifthe operation of water discharge from reservoir was more than 70 m3/s. The research suggeststhat discharging operation from reservoir can be used as an indicator for the early warningsystem for the fisheries activities in the reservoir.Keywords: Jatiluhur reservoir, current velocity, phytoplankton abundance, reservoir operation,two-dimensional multilayer equation

Abstract

ABSTRACTCharacterisation of Organic Carbon of Up Stream Citarum River Water from Domestic andIndustrial Waste Effluent. The local government of Citarum upstream area has conducted theriver cleaning program to increase Disolved Oxygen since 1991 until now. The program hasimpacted to installments of to wastewater treatment for 80% industrials in the Upper Citarumdrainage area declining the load of BOD5 wastewater. However most of waste water comingfrom Banung population have been treated in the collective wastewater treatment (IPAL) ofBojongsoang. Nevertheless, the low concentration of Dissolved oxygen which is under theminimum stream standard concentration, 3mg/l still becomes a problem until now. Anineffectiveness of improvement of the DO is caused by the treatment effluent BOD5 load fromdomestic and industrial wastewater and low awareness industrial wastewater aboutcharacteristics of river water quality . This research aimed to characterize the BOD oxidationrate and BOD5 regime of each river reach base on wastewater domestic or industrial characteristic.The result of this research can then be applied to build the priority of the load reduction ofBOD5 wastewater domestic or industrial in each reach of that river. The characteristic ofoxidation rate have investigated at influent point and water body of Upper Citarum River bymultivariate cluster observation. The oxidation rate was calculated by least-square methodfrom BOD data. The BOD observation was measured by BOD meter everyday for 5 days. Theresult shows that Curugjompong at 0 to 21st km and 36th km to Majalaya bridge ischaracterizedby an industrial sewage, while the upper Citarum at 21 to 36 Km is characterizedby an domesticsewage.Key words: Characteristic, oxydation rate, Citarum river, organic carbon.
