Detailed 20 meters core sampling of sediment was carried out from the recent deltaic Kaligarang, northern part Semarang, Central Java. The main objective of this research is to predict environment changes according to some parameters sedimentation process, for example grain size, organic and inorganic content and the occurrence of benthic foraminifera. The core was analyzed by destructive techniques. The sediment record indicated that the silt grain size dominance deposited in littoral to inner shelf with high organic content than inorganic.
