Badung River is one of the river that across Denpasar city. As one of the rivers that passes through the city with a very dense population, along the river there are activities that has potentially degrade water quality. The aims of this study are to determine the water quality trend and status of water quality standards of Badung River from 2006 to 2009. The result analysis showed the water quality on Badung River declined in the upstream section and relatively stabl e in the middle and downstream section. This situation is result of the waste sources is relatively constant throughout the study period. The existence of DO, BODS, Nitrites, Phosphates, Coliform, and E. Coli is the water quality parameter that always exceeds the threshold of quality standard.

In order to maintain the environmental carrying capacity of coastal tourism, this research was conducted to determine the condition of river water environmental pollution in the Petitenget beach area and pollutant source activities. Determination of water quality is carried out by analyzing the water quality taken at several sampling points in the four rivers that lead to the Petitenget beach. Determined the pollution index value (IP) of the physical chemical and biological pollution parameters. The results showed that the four rivers that flow into the Petitenget Beach area had been contaminated with indications of pH, BOD, COD, ammonia, Coliform and E. coli which exceeded water quality category III class quality (PerGub Bali No 16 Year 2016). The four rivers are included in the criteria of severe contamination. The four rivers have experienced physical damage or structural changes that have very high discharge fluctuations both in quantity and quality. Slimy basic structure, smelly and slum aesthetic waters. While the indication of the impact of pollution is waste water which is directly discharged into the river from hotels, restaurants, homestays, commercial centers and settlements.

Livestock waste that is thrown away without being processed will cause environmental pollution, therefore an effort is needed to process the livestock waste is to be processed into organic fertilizer. The part of livestock waste that can be used as organic fertilizer is urine, in this study goat urine is used. This study aims to find the best nutrients for seeding active suspension, look for the optimal dosage and time for processing goat urine into N fertilizer. The method used in this study is to immobilized the active suspension into the ammonia oxidizers pellets for later used in the goat urine treatment process with an aeration system, so that a nitrification reaction occurs which results is decrease ammonia and nitrite levels and increase nitrate levels. The results obtained in this study are the nutrients that are best used for seeding active suspension are media II that is 5 grams NPK fertilizer; 2,5 grams NH4Cl; and 5 grams glucose with MLVSS values ??of 9000 mg/L at 18 hours. The processing of goat urine obtained optimal results at pellet dosage of 20% (w/v) with optimal time at 18th hour. Ammonia level obtained was 5.6811 mg/L, nitrite levels of 2.3992 mg/L, and nitrate levels of 10.6618 mg/L. Keywords: Immobilization; active suspension; MLVSS; pellets; ammonia oxidizers; nitrification
