Abstrak: Eutrofication is an
increase of nutrient supply (nitrogen and phosphor) to a very high
concentration and above the li-mit that the nature can cope with. This re-cent
research was aimed to predict the eu-trofication of the waters based on the
distri-bution of nutrients and chlorophylla and conducted on November 2012. The
resear-ch was carried out by considering two main parameters which were main
research para-meters and supporting parameter over physi-cal, chemical and
biological variables. The main research parameters consisted of to-tal N and P,
chlorophyll-a and dissolved oxygen of which those variables were the main
variables used in the TRIX index ana-lysis (an index used to characterized the trophic
status of a body of waters). The fer-tility status of Kendari Bay based on TRIX
index was categorized as eutrophic having TRIX index of 5.12. It is confirmed
that the level of nutrient (TN and TP), chlorophyl-a and water clarity determines
the fertility status of a water body ranging from oligo-trophic to
hypertrophic.
