Abstract

Tourism-driven activities have increasingly contributed to marine microplastic (MPs) pollution, particularly in island ecosystems. This study assesses the abundance, characteristics, and spatial distribution of MPs in Gili Trawangan, Indonesia, by analyzing samples from coastal water, sediments, and fish across three zones: a seaport, recreational beach, and mangrove area. Standardized filtration, density separation, and FTIR spectroscopy were used to identify MPs types and polymers. Results show the highest MPs concentrations in coastal water at recreational beaches (19.25 particles/L), sediment at seaports (23.15 particles/kg), and fish near seaports (17.5 particles/individual), indicating elevated risks of bioaccumulation. Fragments and fibers were the dominant forms, with prevalent polymers including PS, PE, and LDPE, mostly in black, blue, and red colors. The mangrove area exhibited lower MPs levels due to its natural filtration capacity but still showed MPs presence in biota. This multi-compartment approach highlights a clear link between tourism intensity and MPs contamination. The findings provide new insights for designing localized interventions, including waste reduction strategies and regulatory measures. By integrating ecological and anthropogenic factors, this study supports the development of sustainable tourism policies to mitigate MPs pollution and protect coastal biodiversity.

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.
