| Summary: | One of the problems can never be solved, is a detergent sewage directly
into water bodies. Waste detergents disrupt aquatic ecosystems. Beside that,
phosphate as filler of detergent can caused eutrophication in waterways. he study
aims to assess the concentration of detergents and phosphates, comparing the
amount of use of detergent in each research area, and the influence of detergent
phosphate pollution of chemical physical factor of river water, also aquatic
organisms (phytoplankton ) as bio-indicators of organic pollution.
This study used a survey method with purposive sampling method. Data
collection was took three times in three research areas, upstream (Dinoyo and
Ketawanggede), middle ( Penanggungan and Samaan) and downstream (Oro - oro
Dowo and Kiduldalem). Sampling was carried out with considering the speed of
the river flow and peak activity in the household wash. Detergents and phosphate
concentration compared with Keputusan Gubernur No.45 Tahun 2002 and
Peraturan Pemerintah No.82 Tahun 2001. Comparison of the use of detergent in
each areas were analyzed by analysis of variance statistic. Effect of detergent
concentration and phosphate to the physical chemical factors of river water and
phytoplankton abundance analyzed by using of multiple regression statistics .
The results showed : ( 1 ) concentration of detergents is not to exceed the
quality standard designation yet, ranging from 0,050 to 0,309 mg / L, whereas the
concentration of phosphate has goes exceed the designation of Class II quality
standards ranging from 0,031 to 0,690 mg / L. ( 2 ) The average use of detergents
slum society in Brantas river bank based on analysis of variance of the pathway ,
were significantly different in each area of study, the downstream use of
detergents has declined. ( 3 ) Detergent and phosphate concentration in Brantas
River influencing the change of turbidity about 61,6 % , dissolved oxygen ( DO )
47,6% and a pH 15%. Concentration of phosphate detergents and also gives effect
to the abundance of phytoplankton at 12,6 % . |
