| Summary: | The accumulation of plastic waste in the ocean, driven by single-use products,
uncontrolled disposal, and poor management, leads to its degradation into
microplastics, a major component of environmental contamination. This study was
conducted to explore the availability of microplastic in the southern coastal areas
of West Java, which are characterized by large waves directly facing the Indian
Ocean. These unique oceanographic conditions could influence the distribution and
characteristics of microplastics, while research about microplastics in this region
remains limited. This study assessed the abundance, characteristics, and polymer
types of microplastics in sediments from three beaches: Sindangkerta Beach,
Karapyak Beach, and Sayang Heulang Beach. Samples were analyzed using
Chemical Wet Peroxide Oxidation (CWPO) and density separation to enhance the
extraction and characterization, followed by polymer identification using FTIR.
The results revealed variation in microplastic abundance across beaches and
depths, with Sayang Heulang Beach consistently exhibiting the highest levels. In
September 2023, the microplastic abundance at Sayang Heulang Beach at a depth
of 10–20 cm was 35 particles/200 g dry sediment, increasing to 51 particles/200 g
dry sediment in January 2024. Seasonal analysis showed significantly higher
microplastic abundance during the rainy season (January) compared to the dry
season (September). Characterization showed that fiber-shaped and colored
microplastics were dominant in all aspect. Polymer analysis revealed the
dominance of Low-Density Polyethylene (LDPE) at 27%, followed by High-Density
Polyethylene (HDPE), Polypropylene (PP), and others in smaller amounts. This
study underscores the complexity of microplastic abundance and highlights the
importance of assessing their distribution, characteristics, and polymer
composition. |
