AB  - A study of the water quality in the Surabaya river is conducted because of its function as the drinking
water supply for the city of Surabaya as well as its support of agriculture, fisheries, livestock, industry and
commerce. The site study is located along ±41 km from the Mlirip dam to the Jagir dam which has a catchment
area of &plusmn;300 km<sup>2</sup>. The complexity of the problems that have occurred so far has caused a decrease in the quality
and quantity of the Surabaya river water. Therefore, an effort to determine the pollution load capacity and
control pollution strategy is needed. Data analysis uses the QUAL2Kw program application to calculate the
pollution load that enters the Surabaya river. Analysis of priorities for water pollution control strategies uses
the Analytic Hierarchy Process (AHP) method. The Surabaya river is divided into seven segments based on
hydraulic data analysis, water quality and pollutant sources. The main parameters used in the QUAL2Kw
simulation are BOD, COD and TSS. The analysis result of the maximum pollutant load for BOD parameters
is 9,161 kgday<sup>-1</sup>, COD is 45,831 kgday<sup>-1</sup> and TSS is 427,079 kgday<sup>-1</sup>. The maximum pollution load capacity
for BOD parameters is 6,958 kgday<sup>-1</sup>, COD is 42,763 kgday<sup>-1</sup> and TSS is 420,167 kgday<sup>-1</sup>. Based on the
results of the AHP program, reducing the pollutant load and increasing the capacity of the Surabaya river can
be determined through the following stages, namely: tightening waste disposal permits, industrial guidance and
supervision, construction of domestic communal WWTPs, development of WWTP industrial area, enforcement
of environmental law and socialization of riverbank communities.
