Abstract

The rapid growth of seafood consumption has raised concerns about food safety due to microplastic contamination in marine organisms. This study investigated the occurrence and characteristics of microplastics in commercially important marine fish marketed in Jakarta Bay, one of Indonesia’s most densely populated and industrialized coastal regions. A total of 160 specimens representing eight species were collected from five major fish markets between December 2023 and January 2024. Microplastics were extracted from gills and gastrointestinal tracts using enzymatic digestion, density separation, and confirmed by ATR-FTIR spectroscopy. Results revealed that 93.8% of the samples contained microplastics, with an average of 3.65 ± 2.34 particles per individual (0.12 ± 0.21 particles/g). Carnivorous and benthopelagic species exhibited significantly higher contamination levels compared to omnivorous and planktivorous species. Most particles were fragments and fibers (~70%), predominantly within the 2000-5000 µm size range. Seven polymer types were identified, with polyethylene, polypropylene, and polystyrene as the most frequent. These findings indicate that Jakarta Bay is a hotspot of plastic pollution, posing potential risks to food security and public health. Continuous monitoring, standardized risk assessments, and improved waste management strategies are urgently needed to mitigate the impacts of microplastic contamination on fisheries and human consumers.

Abstract

Labuan Bajo has experienced rapid tourism growth over the past decade, accompanied by increasing pressure on its coastal environments. This study aimed to examine the spatial distribution and composition of marine debris in intertidal areas and to provide an initial assessment of potential ecological implications. A descriptive survey approach was applied through field observations at selected coastal sites representing varying levels of tourism intensity. Marine debris was quantified using standardized sampling units and classified into major material categories, with further sub-classification for plastic items. The results showed that debris distribution varied across locations, with higher densities recorded in areas with intensive tourism activity. Plastic dominated the debris composition, particularly single-use packaging, plastic bags, and food-related items. Fragmented materials were also observed, indicating ongoing degradation processes that may contribute to microplastic formation. Differences in debris accumulation appeared to be influenced by local human activity and site characteristics, including accessibility and shoreline features. These findings suggest that tourism-derived debris has begun to exert measurable pressure on coastal ecosystems, especially in intertidal zones where biological interactions are frequent. While this study does not directly assess biological impacts, the observed patterns indicate potential risks related to ingestion, entanglement, and habitat disturbance. The study provides baseline information that can support future ecological monitoring and more detailed investigations in tourism-dominated coastal systems.
