1.Introduction

Water is one of the basic resourcesin human life, therefore, meeting its demand means providing not only available quantity but also uncontaminated quality [Sudarmadji et al., 2011]. Surface water is easily polluted, leading to water quality deterioration and low abstraction. Part of water resource management, particularly of surface water, is minimizing human impacts on water quality. Therefore, assessing the Pollutant Carrying Capacity (PCC) of related surface water becomes necessary.

PCC represents the capacity of water source to 'allow' the presence of certain Pollutant Load (PL) from various sources without contaminating its quality (Decree of the Indonesian Minister of Environment No. 1/2010). PCC cannot be assessed directly because it involves a complex interrelationship between its factors. In order to simplify it, PL is assessed using Qual2Kw method, i.e. a numerical modeling of river water quality [Abdi, 2011]. Qual2Kw models are used as river water quality management tools because they emulate the response of water bodies to pollution. Accordingly, they are referred to as the guidelines for policies, regulations, and permits on disposing pollutant into river channels [Oliveira et al., 2012], and for the formulation of water quality management strategies [Kannel et al., 2007].

Qual2Kw is the renewal of Qual2E and Qual2K. Qual2E is a modeling method developed by Brown and Barnwell [1987] that simplified the condition of water quality along the rivers especially based on the level of Dissolved Oxygen (DO) and Biological Oxygen Demand (BOD) [Fatmawati et al., 2012]. Park and Lee [2002] developed Qual2E into Qual2K with additional tools, such as extensive computation structures, more representative water quality parameters (i.e. BOD, DO, and denitrification), and an increase in the quantities of confluence, river segments, and measurement elements. The latest development, Qual2Kw, is equipped with the ability to simulate various water quality parameters, including Electrical Conductivity (EC), temperature, DO, CBODslow, CBODfast, Phosphate, Nitrogen, phytoplankton, detritus, pathogen, alkalinity, pH, etc. [Pelletier et al., 2006].

Bedog River flows through a highly dense residential area, agricultural land, and industrial area. Intensive development and construction along the river, which potentially lead to negative impacts on the environment [Sudarmadji and Widyastuti, 2014], have raised a concern on river water quality. Hence, this study specifically chose Bedog River and used its surrounding land utilization as an approach to represent the pollution emission factor required in assessing the PL potential of domestic, agricultural, and industrial activities in every village in the study area through weighted average calculation.Accordingly, this study developed a water quality modeling based on two key parameters of pollutant loads, i.e. BOD and COD.

The water quality modeling aimed to: 1) quantitatively measure the Pollutant Load in every surveyed segment of Bedog River, as indicated by Biological Oxygen Demand (PLBOD) and Chemical Oxygen Demand (PLCOD); 2) assess the Pollutant Carrying Capacity of every river segment in terms of Biological Oxygen Demand (PCCBOD) and Chemical Oxygen Demand (PCCCOD); and 3) quantify the amount of PLBOD and PLCOD that should be reduced to meet the PCCBOD and PCCCOD of Bedog River.
