Abstract

Benthos macroinvertebrates have been used as bioindicators to assess the waters quality of the stream, but still are very rarely to applied in West Papua streams. Benthos macroinvertebrates can describe the stream water quality so that very well be used as bioindicators, due to each species has a different tolerance to interference organic pollutants in waters. This study aimed to assess the water quality of Nimbai stream using benthos macroinvertebrates tolerance level and several water quality parameters. Data retrieval was conducted in JuneJuly and SeptemberOctober 2012 in seven stations (L1L7) from Nimbai upstream to downstream that connected to Prafi river. The water macroinvertebrates were taken using surber with mesh size 200 μm and then was identified at the family level. At L5 station near the oil palm waste disposal installations was contains oil and fat (<1-3 mg/l), which resulted in dissolved oxygen (DO) and pH is lower than the other stations. Similarly the value of H' is low (0.83), however, the value of C (0.79) was high that dominated by Oligochaeta. Famili biotic index (FBI) value obtained showed that water quality in the L1L4 stations was in good to excellent condition, but the quality at L5 station is classified as very poor. As the distance far away from the sources of pollution in the L5 station, water quality tends to improve as shown in the L6 and L7 stations. The result of this study shows the important benefits of benthos macroinvertebrates as bioindicators for assessing the quality of stream waters, and can be described aquatic environments disturbance to the benthos macroinvertebrates habitats in Nimbai stream.

Abstract

ABSTRACTUtilization around of Belau Rivers was diverse, such as agriculture, industry, households, hotels, markets, residential population and fishing boats. According to the explanation, the purpose of this study was to determine distribution and concentration distribution patterns of Pb, Cd, and Cr which evaluated from the distribution of salinity, calculate the assimilation capacity in marine and analyzing the direction of environmental management Estuary Belau at Lampung Bay. The data was analyzed by using the view pattern of relationship between dissolved heavy metals and salinity through mixing graph approach. Furthermore, to know the pollutant load and capacity of assimilation were use a graph of the relationship between the concentration of each parameter with pollutant load on these parameters. The results analysis of pollutant loads and assimilation capacity showed that the parameters of TSS, BOD and COD were still able to perform self purification, whereas for the parameters of nitrate, phosphate, Pb, Cd and Cr were unable to perform self-purification. The management must be built not only within the autority of Lampung Government and the staffs, but also must be holistic upstream to downstream along the river that involves several government autority. Keywords: Pollution Load , heavy metals, the assimilation capacity, Estuary Belau

Abstract

Sanggeng traditional market that located in the coastal area of Manokwari city as a community trade center which providing daily community needs. Generally, the commodities that available are either household need, fish market and agriculture products, in addition due to market location in the city center it effects to highly community activities. Thus, effect to uncontrolled organic waste is source from mainly agricultural product, fishes, and also from others organic products. This condition is happening in highly intensity and still continues everyday, so it could affect to waters environmental degradation. Indicator that used to assessing water quality degradation based on highly organic waste is by assessed organic concentration then comparing with KLH 51 year 2004. Based on result of turbidity and dissolved oxygen parameter was found that highly condition at BLK location. In addition, highest TSS and TOM was found at waters around of hadi Mall. Highest BOD5 concentration was found in around of Fish market waters. Tides factor also effected to physical and chemical distribution in these waters. This condition shows that organic waste impact to water quality at Sawaibu Bay could affect to waters organisms’ life
