ASSESSING WATER QUALITY INDEX IN RIVER BASIN : FUZZY INFERENCE SYSTEM APPROACH
Water Quality Index is an important water assessment that sustain and conserve the aquatic ecosystem. In Malaysia,
the current classi ication practice on Department of Environmental Water Quality Index (DOE WQI) shows rigid
value in term of assessing the input of parameters that close to a class boundary. Hence, this study proposed a
technique to assess the parameters in a holistic manner by using the Fuzzy Inference System (FIS). The approach
as an assessment tool represents the classes of various ranges and aggregating the parameters using membership
function and Centroid Function respectively. A numerical example based on actual data from one of the sampling
station from Inanam Likas River Basin was adapted in this study. It was adapted to demonstrate the proposed
approach. Findings shown using the proposed methods indicate that the river has Poor water status. Overall, FIS
is able to assess the parameters and execute into a single index that represent the condition from poor to excellent
scales of the water qualit
