Based on this research, Berta Putri successfully earned her doctoral degree with the distinction of very satisfactory, under the supervision of Prof. Dr. rer. nat. Drs. Mufti Petala Patria, M.Sc. as promoter, and Prof. Dr. Ir. Dietriech Geoffrey Bengen, DEA, along with Dr. Riani Widiarti, S.Si., M.Si., as co-promoters.<\/p>\n\n\n\n
The study revealed striking findings: mangrove sediments contain significant amounts of microplastics, predominantly black and blue fibers, with polyethylene (PE) and polypropylene (PP) as the main polymer types. Large particles (>1,000 \u03bcm) were frequently detected, indicating that many originate from local activities such as textiles, fishing nets, and single-use plastics that have not yet degraded. This means that microplastics can accumulate within mangrove ecosystems, enter the bodies of animals, and potentially penetrate the food chain, posing a threat to both biota and human health.<\/p>\n\n\n\n
\u201cWe also found that microplastics are not merely a physical pollution issue, but can alter ecosystem interactions, including microalgal communities that form the base of the mangrove food chain. These findings open up opportunities for more precise and sustainable management strategies,\u201d Berta explained, highlighting the impacts of microplastics on mangrove ecosystems and their implications for sustainable environmental management.<\/p>\n\n\n\n
Microplastics were also detected in the bodies of Telescopium telescopium and Geloina erosa, with distinct patterns corresponding to their respective feeding habits. T. telescopium predominantly ingests particles from sediments, while G. erosa ingests them from the water column. This makes both mollusks potential bioindicators of plastic pollution in mangrove ecosystems.<\/p>\n\n\n\n <\/p>\n\n\n\n In addition, microplastics serve as a new substrate for epiphytic microalgae, known as the plastisphere. Although their abundance and diversity are lower than those found in sediments and the water column, diatom communities of the phylum Bacillariophyta remain dominant, particularly the genera Navicula and Nitzschia. These findings indicate that microplastics are not merely a physical problem but can also alter the structure of microbial communities in coastal ecosystems.<\/p>\n\n\n\n The research was conducted during the east monsoon (September\u2013October 2022) and the west monsoon (May\u2013June 2023), with sediment samples collected to a depth of 30 cm and water samples obtained using a plankton net. The results showed the highest microplastic abundance at Station 3 (Kota Karang, 1,260 particles\/kg) and the lowest at Station 5 (Pulau Kelagian, 220 particles\/kg). The highest levels in biota were also recorded at Station 3 during the east monsoon, reinforcing the link between human activities and microplastic contamination.<\/p>\n\n\n\n These findings are expected to serve as a scientific basis for sustainable mangrove management, the protection of biodiversity, and the health of coastal communities.<\/p>","protected":false},"excerpt":{"rendered":" Depok, 6 Januari 2026 \u2013 Mikroplastik kini menjadi ancaman serius bagi ekosistem mangrove.
