Karakteristik dan Distribusi Spasial Bahan Organik Pada Sedimen Dasar Perairan Teluk Pacitan Jawa Timur

Pacitan Bay is one of the semi-enclosed waters on East Java's south coast. This area well-known for having a large fishing port as well beach tourism area. The dynamics Bay's due to influence currents, waves, and input water masses from mainland are thought affect characteristics waters' bottom sediments. objective this study was map sediments distribution organic substance. research also analyzed relationship between sediment concentration subtance in sediment. sediment's were determined using granulometric analysis, matter content Loss Ignition (LOI) method. analysis results show that sandy substrates dominate by an average 82.22%. substrate dominates bay's north west. Distance shoreline has significant effect (One Way ANOVA, F = 6.05; p 0.05). dominated sand lower (R2 0.76) compared with softer grain size (silt or mud) tighter pores, making efficient precipitate.
