Population growth followed by an increase in laundry activity generates waste if left unchecked will cause damage to aquatic biota. To overcome this need the existence of an environmentally benign laundry water treatment system such as biosystem. Biosystem used in this research with length 180 cm width 60 cm and height 40 cm filled gravel as filter media and elephant grass (pennisetum purpureum) plant. The way of operating the biosystem is by pouring the waste into a tub of biosystem and then samples waste water taken on the biosystem output. The result treatment that biosystems combined with anaerobic reservoirs decreased BOD, COD, phosphate and detergent levels by 127.09 mg/l, 161.96 mg/l, 0.8699 mg/l and 1.3228 mg/l in a single treatment on roughing horizontal flow filter for laundry water treatment. The performance of physical and biological components in biosystems combined with anaerobic reservoir effectively decreased BOD, COD, phosphate and detergent concentrations by 73.91%, 69.58%, 58.74% and 80.03% (above 50%) in one treatment. But only in lowering the effectiveness of phosphate levels is still relatively low when compared with the effectiveness of wastewater quality standards. Further research needs to be done calculations to find plants in biosystems that can thrive. In addition, further research is needed to find the operating time until the biosystem undergoes a breaktrough condition. Keywords: laundry, waste water, biosystem.

parts of sampling areas: Sanur Kaja 5-6 meter (SA2) and 7-8 meter (SA3), Kelurahan Sanur 3-4 meter(SB1) and 5-6 meter (SB2), Sanur Kauh 3-4 meter (SC1) and 5-6 meter (SC2), using Cluster RandomSampling method.The result in April showed that from 14 parameters examined only 5 parameters have highconcentration than the acceptable drinking water standard (PPRI no.82, 2001). Those parameters areDissolved Oxygen (DO), Biochemical Oxygen Demand (BOD5), Nitrate (NO3), Phosphate (PO4), and TotalColi form. While the result of the analyses in June showed that 9 from 14 parameters have highconcentration than the acceptable drinking water standard ( PPRI no 82, 2001) they are Total DissolvedSolid (TDS), Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD5), Nitrate (NO3), Nitrite (NO2),Ammonia (NH3), Phosphate (PO4), E. coli and Total Coli form.The increasing concentrations indicate some pollution has occurred in these sampling areas. Theobservation has shown that most of the people in Sanur dump their waste water into the ground, which easilyabsorb through the porous soil then contaminate the ground water aquifer. Based on the water quality status using the pollution index, almost all the sampling areas have low pollution index, except the one at SanurKaja 7-8 m (SA3) has moderate pollution index.

Artificial reefs are made to act as temporary substitutes for small areas of damaged original reef. The structures attract fish and other marine organisms, which can eventually be exploited (e.g. for human food), so it is expected that they will form the basis around which natural reefs can grow and recover. The purpose of this study is to document recruitment of organisms onto the artificial structures, evaluate the effectiveness of the structures in terms of shape and recruitment potential, and use the recruitment information to show which species occur in the surrounding reefs. This research was conducted from May-July 2010 in north Bali, in the Village District Gerokgak Patas, Kampung Baru Village in Buleleng District, and Penuktukan Village, Kecematan Tejakula. The research method used was a visual census method to determine the number of fish species and fish abundance on artificial reefs at three different locations. Three replications were performed at each location. 2481 individuals from 18 families (38 species) of reef fish were observed. The area with the greatest abundance of fish and the highest number of fish species was in Kampung Baru, with 1170 individuals from 21 species of fish. Dominant reef fish species were Plotosus lineatus (Cat Fish) - 510 individuals, Pomacentrus auriventris (Goldbelly damsel)- 256 individuals, Dascyllus trimaculatus (Three spot damsel) - 335 individuals, Pseudanthias squamipinnis (Lyretail Anthias) - 320 individuals. A Sorensen analysis showed that reef fish communities on the artificial reefs in the form of 'hexadomes' were not derived from the surrounding reefs.

The diversity of activities along the Brantas watershed causes waste disposal, which contributes to an increase in pollution load in the Brantas watershed and a decrease in water quality. It is necessary to periodically monitor water quality changes, but the constraints faced are the high cost of sample testing. The solution that can be done is to predict changes in water quality through the neighborhood method to reduce the number of samples. The purpose of this study is to predict the water quality conditions spatially by using the Inverse Distance Weighted (IDW) method, especially in the watershed area of ??Batu Upper Brantas and find out the differences in the spread of pollution water in the conditions of the rainy and dry season, as the last output is to determine the water purification zone. The IDW method is able to visualize the spread of water pollution with distance-based interpolation calculations, where the advantages of IDW compared to other methods are that the calculations are at the minimum limit and the maximum limit of input values. The results obtained from this study were from 13 sampling points obtained 1 point experienced an increase in pollution status in the rainy season to dry season, namely from weight to moderate, 1 sample point that experienced changes in pollution status from mild to moderate, 7 points experienced a change in status from moderate to severe and 4 sample points experiencing changes in status from mild to severe. Branats River degradation zone upstream of Batu City at a distance of 2 km has experienced a decrease in DO during the rainy and dry season, the decomposition zone of Sunga Upper Brantas in Batu City is at a distance of 3 km to 6 km in the rainy season, and at a distance of 3-4 km dry season conditions , rehabilitation zone in the Brantas River in the Upper Batu City at a distance of 7 km to 8 km in the rainy season and at a distance of 5-11 km during the dry season and a re-purification zone, there was no purification zone at a distance of 11 km along the Brantas River in the Upper Batu City. Keywords : distribution, prediction, purification zone, water pollution
