Markov model, Principal component analysis, Primary pollutant, Saguling reservoir, Water quality indexAbstract
This study aims to identify how the dominant parameter selection may show pollutants source
in every segment of the reservoir, be it reservoir input segment, reservoir middle segment or body reservoir
segment, and reservoir outlet segment that turns out to be diverse. Water Quality Index (WQI) value in this
study was calculated for each parameter chosen based on the Principal Component Analysis (PCA). In
addition, this study showed that pollution in the rainy season was lower that the pollution in the dry season,
this was indicated by the WQI values obtained. This study also showed that the reservoir input pollution
source was dominated by domestic activities and industry, while the middle segment of the reservoir usually
polluted by floating nets activity, and in the reservoir outlet, pollutant accumulation occurred as indicated by
the presence of H2S as the main pollutant.
