The environmental situation of the estuarial ecosystem Teluk Klabat that islocated at the northwestern coastal area of Bangka was evaluated on the basis of the physical, chemical and biological data derived from direct in-situ field survey during the southeast monsoon (dry season). The objective of this study is to understand the environmental characteristics and water quality status of the Teluk Klabat to support fisheries development within this area. The result shows that the sedimentation process at theTeluk Klabat has been ocurred excessively and it caused decreasing of the bathymetry reached only 1 m that is found almost in a whole of the coast line area at the inner side of the Teluk Klabat and it extended up to more than 2.5 km from that coast line. More over, the terrestrial environment seem to have strong effect on the degradation of the water quality at the Teluk Klabat that is shown by high concentration of the nutrient (nitrate, phosphate, silicate) and heavy metal such as Pb and Cd. While chlorophyll-a concentration was also high. It indicates that the Teluk Klabat tend to be eutrophycation.

ANALISIS MODEL SEBARAN BAHAN PENCEMAR Dl PERAIRAN SELAT NGUAN, BATAM Sachoemar, Suhendar I; Purwanda, Andri

Analysis of the pollutant transport model was conducted to understand themagtitude, their pattern and spreading speed of the pollutant at Nguan narrowchannel of Batam. The RMA2 (Resource Management Associates) analysis wasemployed to solve those phenomena. The target analysis of the pollutant issuspended particulate matter (sediment), a rnost dominant pollutant matter withinthis area. The result shows that the spreading pollutant was strongly associatedwith the monsoonal system, current speed, tidal system and the pollutant source.The southward direction of sediment transport was inluenced by the northwestmonsoon and the tidal flood. While the northward direction was affected by thethe southeast monsoon and the ebb tide. The current speed was identified asmain factor causing the flushing out magnitude of the water mass at the channel, inwhich the flushing out in the northwest monsoon was faster than that in the southeastmonsoon. As consequence, the water resident time was to be short, the pollutantwas easily to be cleaned out and as the result, the water quality within the channelwas to be excellent.
