Abstract

Mutun Coastal has a diversity of biota species. Biota that are commonly found include the mollusk phylum (Bivalve and Gastropod classes). The purpose of this study was to determine the diversity of mollusks (Bivalves and Gastropods) on Mutun Coastal Lampung. This research was conducted on February 5-7, 2021. The method of data retrieval at both stations used the belt transect method by purposive sampling. Station I is substrated fine sand, while station II is substrated by coarse sand. Based on the research conducted, 26 individuals were found consisting of 7 families, namely 6 families of the Gastropod class (Trochidae, Strombidae, Cerithiidae, Muricidae, Potamididae and Pisaniidae) and 1 family of the Bivalve class, namely the family Mactridae. The value (H') at station I is 1.44.  At station II it has an H' value of 0.86. The value of H' at station I belongs to the medium category. The H' value at station II belongs to the low category. The value of E at station I is 0.72. While at station II it has a value of 0.1. The evenness value at station I belongs to the high category. The value (E) at station II of the evenness index belongs to the low category. The value (D) at station I is 0.57. While at station II it has a value of 0.35. The value of D at station I belongs to the medium category. The value of D at station II belongs to the medium category. Based on data analysis, Mutun Coastal has suitable habitat for mollusk and it is also supported by abiotic parameter conditions.

Abstract

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.
