KOMUNITAS DIATOM PADA EKOSISTEM MANGROVE PANTAI UTARA JAWA TENGAH
ABSTRACT: Diatom is a unique
microalgae, undoubtly good bioindicator of water quality, andable to be usedf
or paleoreconstructione nvironmentacl hangesI.t s relatedt o the silicious
frustule,t hat remainpreserved in the sediment. Diatom have widespread
distribution, including in the mangrove ecosystem.Mangrove€ cosystema lso
unique, influenceb y freshwatera nd salinew ater, therefore,t he biodiversity
in themangrovee cosystema re very high. However,t he sharpd egradationo f
mangrovee cosystemin the NorthernCoast of Central might reduce the
biodiversity, particularly diatom. This research is conducted in order tostudy
the diatom community vertically in the Norther Coast of Central Java and their
correlation with waterquallty. From 54 sediments amples, 147 diatoms speciesw
are identified, 10.88% of Centrophycidaea nd89.12o/o of PennatophycidaeP.
