Abstract

The coastal waters of Simpang Pesak Sub-district, East Belitung Regency considered as a productive region and had a broad range of habitats for bivalvia. However, research on spatial distribution and habitat preference of bivalvia in this region is limited to none. The objectives of this research were to examine the effects of marine biophysical parameters and substrate quality on bivalvia. The research was started from Mei 2013 until June 2013 by using survey method and random systematic sampling approach. The results showed that there were 16 species of bivalves consisted of 14 genus from 7 family and dominated by Gafrarium pectinatum at station I (13.62 ind/m2, C=0.52, H’=0.6, muddy sandy), and  station II (28.4 ind/m2, C=0.51, H’=1.04, sandy), Gafrarium tumidum at station III (59.9 ind/m2, C=0.51, H’=1.03, sandy), Scapharca pilula at Stasiun IV (61,6 ind/m2, C=0.5, H’=0.89, clay sandy). Spatial distribution and density of bivalves were influenced by particle size, C-organik, and other environmental factors such as current, dissolved oxygen, TSS, temperature, and salinity.

Abstract

The Baturusa River receives input from various activities ranging from industry, mining, fisheries, large-scale plantations and shipping ports. This research aims to determine the concentration of the heavy metals Copper (Cu) and Zinc (Zn) as well as the status of the level of contamination, contamination and enrichment of the heavy metals copper (Cu) and zinc (Zn) in Baturusa Waters, Bangka Belitung Islands Province. Heavy metal analysis using the AAS method. Concentrations of heavy metals Cu and Zn ranged from 0.73-2.29 mg/kg and ranged from 1.45-14.74 mg/kg. The contamination factor values for heavy metals Cu and Zn are included in the low contamination level (CF<1) with a range of Cu 0.016-0.050 and Zn 0.015-0.155. The results of the I-geo value for Heavy Metal Cu range from -4.881 to -6.530 and for Heavy Metal Zn range from -3.273 to -6.618 which shows that the I-geo value (<0) means it is not contaminated with heavy metals. The PLI value ranges from 0.01-0.08, indicating it is not contaminated. The EF value for the heavy metal Zn is greater than for the heavy metal Cu (Zn>Cu), the value for Cu is 2.32-7.54 and Zn 2.59-11.27. The EF values of the heavy metals Cu and Zn are included in the moderate to sufficient enrichment level category. Variations in EF values in the waters of the Baturusa Estuary, Bangka Belitung Islands Province show that there is input from anthropogenic sources at all stations as well as input from natural weathering processes from land (both physical and chemical).
