Abstract

Kecinan Beach is one of the beaches on Lombok Island with many tourism activities. The activities in Kecinan Beach can influence the water quality, as the waters may receive waste from surrounding areas, leading to potential pollution or a decline in water quality. Phytoplankton are living organisms that can indicate whether a water body is polluted, which can be marked by changes in the community structure of phytoplankton, particularly in abundance and diversity. Water quality based on phytoplankton diversity as a bioindicator in Kecinan Beach has not been reported. This study was conducted to analyze the water quality of Kecinan Beach based on phytoplankton diversity as a bioindicator. Samplings were carried out in 9 sites in 3 stations during the month of March to June 2024. Samples were collected using a plankton net of 20µm mesh size. Samples were preserved in 4% formalin preservation and laboratory observation was conducted in the biology laboratory of FMIPA University of Mataram. The study identified 56 species from  3 classes, 21 families and 30 phytoplankton genera. The phytoplankton abundance in the coastal waters of Kecinan Beach was 126.667 ind/L. The species dominance index of phytoplankton of coastal waters of Kecinan Beach was 0.258, indicating no species dominance to each other. Rhabdonema arcuatum was identified as the highest (158%) species importance value. The species diversity index of phytoplankton of the coastal waters of Kecinan Beach was a moderate category. Based on the species diversity index, it can be said that the waters of Kecinan Beach are not polluted.

Abstract

Microplastics are small particles <5 mm produced from plastic waste. The plastic waste thrown in the sea, As a result, microplastics have increased and are widespread almost throughout the sea surface, including Tanjung Luar Fish Landing and East Lombok Regency. Microplastics are very dangerous for human health due to microplastic contamination in feather clams, which are often consumed by the local community.  Microplastics in the shellfish body can accumulate from the food chain and enter the digestive system. This study aims to determine the presence and characteristics of microplastics in feather clams (Anadara antiquata) at Tanjung Luar Fish Landing, East Lombok Regency. The research method used was descriptive quantitative. Samples of feather clams obtained from Tanjung Luar Fish Landing were separated from their shells. The clam meat was added with 10% KOH to destroy organic matter. The sample was incubated in a water bath until it was homogeneous. The sample was filtered using a 250 µm sieve. The filter results were dried with a dryer at 40˚C. Samples were identified with a microscope. The results showed microplastic contamination in feather clams from Tanjung Luar Fish Landing. Microplastic particles found were 59 particles with fibre types, as many as 47 particles, films 9 particles, and fragments 3 particles; there were 4 types of colours: black, clear, red and green. The dominant microplastics found were of the fibre type. Feather clams contaminated with microplastics harm human health, including metabolic disorders.

Abstract

Climate change and excessive anthropogenic activities have an impact on coral reef damage. Coral reef damage can be seen from several criteria, one of which is the percentage of live coral cover. North Lombok is one of the districts on Lombok Island whose coral cover has been damaged.  This research aims to identify marine biota, coral reef genus, analyze community structure and condition of coral reefs at Mentigi Beach. Coral reef genus data was taken using Coral Finder 2.0 Indo Pacific by Russel Kelley, while coral reef data was obtained using the UPT (Underwater Photo Transect) method at three stations with depths of 1-5 meters and 6-10 meters. The results showed that live coral cover at stations I, II, and III were 12.44%, 17.42%, and 32.46%, respectively. At a depth of 1-5 meters, it was found to be 21.93%, and 19.62% at a depth of 6-10 meters. There are 11 benthic categories, and 30 coral reef genera identified. The Porites genus is cosmopolitan in the research location. The diversity, evenness and dominance indices show that coral reef genera are evenly distributed with no one dominating the coral reef ecosystem at Mentigi Beach, Pamenang, North Lombok Regency.

Abstract

This study aims to examine the structure of sea urchin (Echinoidea) communities in the tidal zone of Kuta Mandalika Bay. The research was conducted in August 2024 at three different stations: River Estuary (Station 1), KEK Tourism Area (Station 2), and Mangrove Ecosystem (Station 3). Data collection was carried out using purposive sampling with line transects and plots to identify species, abundance, and environmental parameters (substrate and salinity). The results identified four sea urchin species: Diadema setosum, Tripneustes gratilla, and Enchinometra mathei. Station 2 exhibited the highest diversity and abundance (H' = 2,31; 68.70% abundance), characterized by a rocky sand substrate and salinity of 30 ppt. In contrast, no sea urchins were found at Station 1, which had a muddy sand substrate and lower salinity (28 ppt). Station 3 showed moderate diversity (H' = 1.77) with 50% abundance. Environmental factors such as substrate type, salinity, and the presence of mangrove vegetation significantly influenced the distribution of sea urchins. This study highlights the critical role of habitat characteristics in shaping sea urchin community structure in the tidal zone.

Abstract

The mangrove forest in Cendi Manik Village, West Lombok Regency, consists of both natural and rehabilitated areas, the latter of which has been developed into the Bagek Kembar Mangrove Ecotourism site. While the growth of ecotourism has increased public and governmental attention toward the rehabilitated zone, concern for the natural mangrove forest has declined. This study aims to identify mangrove species composition and analyze vegetation density and diversity in the Cendi Manik mangrove area. The research was conducted from February to March 2024 using vegetation analysis methods across 15 plots distributed along three transects. The results identified six main mangrove species: Avicennia marina, A. alba, Rhizophora apiculata, R. mucronata, R. stylosa, and Sonneratia alba, with Rhizophora mucronata being the most dominant species, having the highest tree density of 440 individuals/ha. The total tree density reached 1,373.34 individuals/ha, which is categorized as dense according to Indonesian Ministry of Environment Regulation No. 201/2004. The species diversity index (H’) ranged from 1.54 to 1.61, indicating moderate to high diversity levels. The dominance of muddy substrates in the area supports the optimal growth of Rhizophora species. These findings highlight the ecological importance of conserving the remaining natural mangrove forests in Cendi Manik Village, given their vital role in coastal protection, carbon storage, and habitat provision for coastal biota. This research serves as a foundation for more comprehensive and sustainable conservation strategies in the region.

Abstract

The presence of Crustacea plays an important role in the processes occurring within seagrass bed areas. One of the coastal waters that contains seagrass beds is Kecinan Beach. This beach is also frequently used by the local community for madak activities, and the high frequency of such activities poses a threat to the seagrass ecosystem and the diversity of Crustacea. Due to the lack of available data on Crustacea in the Kecinan Beach area, this study is necessary to understand the community structure of Crustacea in the seagrass ecosystem of Kecinan Beach, Pemenang District, North Lombok. Data were collected using the line transect method, with each transect measuring 50 meters in length. Along each transect, 1×1 m² quadrat plots were placed. The Crustacea community structure found in the seagrass ecosystem of Kecinan Beach, Pemenang District, North Lombok, consisted of 14 families and 31 species, with a total of 155 individuals. The diversity index at stations I, II, and III was classified as moderate. The evenness index at stations I and II was high, while the evenness index at station III was moderate. The dominance and abundance indices indicated that each station had low species dominance and low abundance.

Abstract

Graphical Abstract   Highlight Research The environmental DNA (eDNA) method successfully identified four species of molluscs (Monetaria , M. annulus, M. obvelata, and Phyllaplysia sp.) and two family taxa (Strombidae and Cypraeidae) from the seagrass and coral reef ecosystems on the Mandalika coast. The species annulus, M. obvelata, and Phyllaplysia sp were detected in the coastal area of ​​Mandalika for the first time using the eDNA approach, although they had never been recorded observationally in this area before. The eDNA method is able to detect species that are difficult to observe directly, such as Phyllaplysia, which have never been reported in the coral reef ecosystem of Mandalika. This study emphasizes the urgency of sustainable coastal area management with an eDNA-based scientific approach to monitor diversity, detect rare species, and evaluate the impact of human activities on the ecosystem.     Abstract Molluscs are one of the main taxa in coastal ecosystems that play an important role in the food chain, bioindicators, and have high economic value. However, the limitations of conventional methods in detecting species that live hidden in complex ecosystems, such as seagrass and coral reefs, are a challenge in biodiversity monitoring. This study aimed to explore the diversity of mollusc species in the Mandalika coastal area using an eDNA metabarcoding approach. This study used the environmental DNA (eDNA) metabarcoding method to identify the diversity of molluscs in the coastal ecosystem of Mandalika, Central Lombok. The sites including Kuta Beach, Gerupuk Bay, and Aan Cape along the Mandalika coastal that contain both seagrass bed and coral reef ecosystems. Two samples were taken from each site in both the seagrass bed and coral reef ecosystems. Analysis of six water samples resulted in 99 ASVs and 116,611 final sequences, with 10 ASVs (50,960 sequences) identified as Mollusca taxa, all from the Gastropoda class. Four species were successfully identified, including Monetaria sp. M. obvelata, M. annulus and Phyllaplysia sp. that had not previously been reported through direct observation or conventional identification methods in Mandalika coastal area. Species diversity varied between locations and was influenced by environmental factors such as temperature, pH, salinity, phosphate, and anthropogenic pressure. These results show that eDNA metabarcoding is an effective tool in detecting mollusc species, even in hard-to-reach habitats, and support the urgency of scientific data-based mollusc conservation management.

Abstract

Microplastics (MPs) have become an interesting topic of discussion especially after many studies reported their presence in aquatic ecosystems. Pollution by microplastic particles in aquatic systems is a critical issue the world that has the potential to damage aquatic ecosystems. Therefore, this study aims to identify the abundance and characteristics of MPs in water, sediment and seagrass in tourist areas. Samples were obtained from three location categories, first the port, second the hotel area and third the residential area located in the Gili Trawangan tourist area, Lombok, Indonesia. After optimization of extraction, characterization was carried out using a stereo microscope to identify MPs. The results show that the average abundance of MPs in the three location categories is, 13.25 ± 17.21; 19.25 ± 23.30; and 16.50 ± 18.52 particles/L at water, 22.00 ± 30.84; 20.00 ± 30.80; and 6.00 ± 8.49 particles/kg dry weight (dry weight) sediment, and 17.50 ± 15.69; 16.25 ± 22.56; and 8.25 ± 8.46 particles/individual at seaweed. Then from this abundance, the types of MPs were found in the form of fragments, fibers, films and pellets, where the dominant colors are black, yellow, blue, red and green, with the highest size < 500 µm. From this study it is necessary to see the impact of MPs on seaweed and the aquatic environment around Gili Trawangan.

Abstract

Microplastics are plastic debris resulting from the fragmentation process that has a size less than <5 mm. Microplastic contamination in marine waters can have a direct impact on the ecosystem and digestive system of aquatic biota, and is dangerous for humans if consumed because it is toxic. This study aims to determine the abundance and characteristics of microplastics in Vaname shrimp (Boone, 1931) collected by Tanjung Luar Fish Landing Base (PPI), East Lombok Regency, Indonesia. Vaname shrimp samples were taken using the Random Sampling method obtained from fishermen at the Tanjung Luar Fish Landing Base, analyzing the abundance and characteristics of microplastics with 10% KOH. The results showed that the abundance of microplastics obtained was 37 particles with the most accumulated type of microplastics, namely the fiber form of 22 particles/gram with the most dominant color, namely black as much as 57%.  There are 3 forms of microplastics found in vaname shrimp meat (Littopenaeus vannamei), namely fiber 22 particles, fragments 11 particles and filaments 4 particles. Black color as much as 57%, followed by clear color as much as 27%, yellow as much as 11%, and blue as much as 5%.
