Malacca River water quality is affected due to rapid urbanization development. The
present study applied LULC changes towards water quality detection in Malacca River.
The method uses LULC, PCA, CCA, HCA, NHCA, and ANOVA. PCA confirmed DS, EC, salinity,
turbidity, TSS, DO, BOD, COD, As, Hg, Zn, Fe, E. coli, and total coliform. CCA confirmed 14 variables into two variates; first variate
involves residential and industrial activities; and second variate involves agriculture,
sewage treatment plant, and animal husbandry. HCA and NHCA emphasize that cluster
1 occurs in urban area with Hg, Fe, total coliform, and DO pollution; cluster 3 occurs
in suburban area with salinity, EC, and DS; and cluster 2 occurs in rural area with
salinity and EC. ANOVA between LULC and water quality data indicates that built-up
area significantly polluted the water quality through E. coli, total coliform, EC, BOD, COD, TSS, Hg, Zn, and Fe, while agriculture activities
cause EC, TSS, salinity, E. coli, total coliform, arsenic, and iron pollution; and open space causes contamination
of turbidity, salinity, EC, and TSS. Research finding provided useful information
in identifying pollution sources and understanding LULC with river water quality as
references to policy maker for proper management of Land Use area.
