“…Hal ini sesuai dengan pernyataan Wahdaniar (2016) bahwa apabila di dalam komunitas itu ada dominasi spesies, maka keanekaragaman spesiesnya rendah. Sedangkan menurut Ratih et al (2021) bahwa nilai kemerataan dan dominasi yang tergolong sedang dipengaruhi oleh faktor lingkungan yang sangat memengaruhi umur moluska dalam substrat. Rendahnya nilai keanekaragaman disebabkan oleh distribusi atau penyebaran yang tidak merata di suatu komunitas (Ridwan et al, 2016).…”

Tanjung Rising Coastal, located in Dendang Village, Bangka Belitung Islands, has a large variety of substrates and organisms. One of the types of marine life studied is the Mollusk Phylum including the Bivalve and Gastropod classes. To find out the diversity of Bivalvia and Gastropoda, this study was carried out on Tanjung Rising Coastal, Bangka Belitung Islands. The study was conducted in December 2020-August 2021, using belt transect method with purposive sampling technique. Samples were collected at station 1 with a sandy substrate and station 2 with a muddy substrate. The results of this study found 1,372 individuals from the Bivalvia class consisting of 7 families and 12 species, while from the Gastropod class yielded 2,630 individuals consisting of 5 families and 7 species. The diversity and evenness index at both stations is relatively low which means that there are species that dominate, because both stations have good habitats for the dominating species. In addition, temperature, pH, salinity, depth, and strong currents showed good values for Bivalvia and Gastropoda habitat. In summary, Tanjung Rising Beach is still a good habitat for invertebrate animals, especially Bivalvia and Gastropoda.

Distribution of Heavy Metals in Sediments and Soft Tissues of the <i>Cerithidea obtusa</i> from Sepang River, Malaysia

et al. 2022

The main purpose of the research was to analyze the distribution of Arsenic (As), Cadmium (Cd), Copper (Cu), Iron (Fe), Nickel (Ni), Cobalt (Co), Mangan (Mn), and Zinc (Zn) in soft tissues, shells, and associated surface sediments of Cerithidea obtusa (C. obtusa) mangrove snails collected from Sungai Besar Sepang. The concentration of iron (Fe) was found to be the highest in relation to other toxic elements in sediments, soft tissues, and shells of C. obtusa. The concentrations of Cu and Zn in soft tissues of C. obtusa were found to exceed the concentrations in sediments, indicating bioaccumulation of these metals. Metal pollution was assessed with the Enrichment Factor (EF), Geoaccumulation Index (Igeo), and Pollution Factor (CF). EF, Igeo, and CF were 0.34 to 22.41, -3.37 to 2.65, and 0.14 to 9.42, respectively. The results indicate that sediments in Sungai Besar Sepang are contaminated with As and Zn. According to the bivalve bioaccumulation results, the soft tissues of C. obtusa act as a macro-concentrator for Cu and Zn. As a result, it is suggested that ongoing monitoring of releases of heavy metals from anthropogenic sources and stricter environmental protection measures should be implemented.
