Abstract

One of the dangerous heavy metals that can build up in aquatic biota is mercury (Hg). The purpose of this study was to evaluate the environmental health condition in possibly polluted areas near Pelangan Village, Sekotong Subdistrict, West Lombok, and to ascertain the heavy metal level in Gracilaria sp. Using samples taken from Pelangan, Elak-Elak, and Mentigi, the Atomic Absorption Spectrophotometer (AAS) method was used to analyze non-essential heavy metal pollution in Gracilaria sp. According to the findings, Gracilaria samples taken from the Sekotong Subdistrict's coastline area had the greatest levels of mercury pollution, with 0.05 mg/kg in Elak-Elak and 0.14 mg/kg in Pelangan. On the other hand, samples of Gracilaria sp. from the Mentigi coast in North Lombok did not exhibit any mercury contamination (0.00 mg/kg). The levels of mercury accumulation in Gracilaria sp. are classified as dangerous since they surpass the 0.03 mg/kg maximum permissible limit for mercury in consumable products established by the Indonesian National Standard (SNI 7387:2009). Additionally, Gracilaria substrate samples from Pelangan had a mercury contamination level of 0.05 mg/kg, greater than that of Mentigi and Elak-Elak (both at 0.00 mg/kg). The proximate content of Graciaria sp was influenced by the sampling location but was not influenced by mercury contamination.

Abstract

Mollusks are an important group of marine organisms that contribute significantly to marine ecosystem structure and function, exhibiting high species diversity and widespread distribution across various marine habitats. Medana Beach, located in North Lombok, is a coastal area with ecological potential as a habitat for mollusks, particularly bivalves and gastropods. However, excessive exploitation beyond sustainable limits has led to a decline in mollusk populations, due to rates of harvest surpassing their natural regeneration. This study aims to assess the species diversity and community structure of mollusks (Bivalvia and Gastropoda) in the intertidal zone of Medana Beach. A purposive sampling method was used to select stations based on differing environmental characteristics, while transects were laid using systematic random sampling. Mollusk sampling, environmental parameter measurements (temperature, salinity, and pH), and substrate identification were carried out at all three study stations. A total of 55 mollusk species comprising 1,052 individuals were recorded, including 14 bivalve species and 41 gastropod species. The bivalves belonged to 9 families, and the gastropods to 17 families. The highest infaunal abundance was observed at Station 3 (616.67 ind/m³), while the highest epifaunal abundance occurred at Station 1 (15.38 ind/m²). Modiolus philippinarum had the highest infaunal density (255.56 ind/m³), found attached to seagrass roots in muddy-sand substrates. Cellana radiata had the highest epifaunal density (6.13 ind/m²), found attached to rocks. The mollusk community structure at Medana Beach was relatively stable, as indicated by moderate diversity and evenness indices, with no dominant species observed. These findings suggest that the habitat conditions at Medana Beach are capable of supporting mollusk communities and are not currently experiencing significant ecological stress.

Abstract

Gastropods and Bivalves are important organisms to study in terms of community because they can serve as indicators of environmental quality due to their sedentary nature. This research was conducted in April 2024 at Kecinan Beach, Malaka, Pemenang District, North Lombok Regency, with the aim of identifying species and analyzing the distribution patterns and abudance of Gastropods and Bivalves in the intertidal zone. Sampling was conducted using the quadrat transect method in three observation areas, each divided based on different activities. In each area, a 50 meter transect was laid out toward the sea with 1 x 1 meter quadrats placed every 5 meters. Data were analyzed to obtain values for abundance, diversity index, dominance index, morisita index and evenness index. The results identified 131 species with 338 individuals, consisting of 107 species of Gastropods and 24 species of Bivalves. Stations I and II, which have good seagrass and coral reef ecosystems, showed a higher number of individuals  compared to station III, which is located near a river mouth. The diversity index at stations II and I was classified as high, while station III had a moderate index. The evenness index at all stations showed a stable distribution pattern. The low dominance index indicated that no species dominated the area.

Abstract

In order to maintain the continuity of the ecotourism area and several infrastructures built in the coast of sekotong, we need to conduct a further research about the bernacles diversity that has a potential to caused damage to the waterfront-city building made with wood, rocks and tiles. This study aims to see the bernacles diversity in three different ecosystems such as mangrove, seagrasess and coral reef ecosystem with three different natural growth medium made with wood, rocks and tiles. The result demonstrated that there's only two species of bernacles found growth and living in all of the growth medium in three different ecosystems. These species were belongs to the genera of amphibalanus and terctralitella The tetraclitella genus only found grow and live on a wooden medium in the mangrove and seagrasses medium. Meanwhile the amphibalanus found mostly in every growth medium om each ecosystems. Thus, made the amphibalanus as dominant genus with the density of 1644,4 individual/m2. Whereas the tertraclitella density were only 22,22 individu/m2.
