Microplastic abundance in the water, seagrass, and sea hare Dolabella auricularia in Pramuka Island, Seribu Islands, Jakarta Bay, Indonesia
AI summary Read the abstract
Researchers measured microplastic abundance in seagrass, water, and the sea hare Dolabella auricularia on Pramuka Island in Jakarta Bay, Indonesia. Microplastics were found in all three sample types, indicating that plastic contamination has penetrated the seagrass ecosystem and is being ingested by organisms within it.
Abstract This research focused on the amount of abundance of microplastics in the sea hare Dolabella auricularia as well as the seagrass fields along the southern coast of Pramuka Island. Sampling of 8 individuals of Dolabella auricularia along with seagrass Cymodocea rotundata leafblades was done at the southern coast of Pramuka Island, after which the samples were preserved and brought to a laboratorium in Depok for microplastic analysis. The sea hares’ digestive tracts were extracted and dissolved in strong nitric acid. A 1 cm 2 portion of a seagrass leaf blade was cut for observation. Prepared samples were observed under a monocular microscope and further analysis was done. Microplastic fibers and film particles were found in highest abundance within the digestive tracts of each sample of Dolabella auricularia as well as on the seagrass surface where the sea hare obtains its algae from, with fragment particles found in much lower amounts. Overall, number of microplastics was found between 40.1 to 73.7 particles/g weight of sea hare digestive tract and the estimated amount of microplastic found at seagrass leafblade was 185 particles/cm 2 . Results provide evidence that microplastics in the ocean brought by water currents could adsorb on to algae through which it enters the food chain as it is consumed by marine biota.

AI summary Read the abstract
Researchers assessed marine debris and microplastic contamination in seagrass beds on Pramuka Island, Indonesia, finding six seagrass species with coverage ranging from 1.67-47.32% and identifying plastic as the most impactful debris type, with fiber microplastics (20-440 particles/kg) dominating and potentially interfering with seagrass respiration and photosynthesis.
Microplastic abundance and its relationship with sediment grain size in seagrass and bare flats of Panjang Island, Banten Bay, Indonesia
AI summary Read the abstract
Researchers surveying Panjang Island in Indonesia's Banten Bay found microplastics throughout both seagrass and bare sediment areas, with finer-grained sediments accumulating more particles. Seagrass beds appeared to trap more microplastics than bare areas, meaning these critical coastal habitats — already under stress — may concentrate plastic pollution and expose the organisms sheltering in them to higher doses.

Abundance and characterization of microplastic pollution in the wildlife reserve, Ramsar site, recreational areas, and national park in northern Jakarta and Kepulauan Seribu, Indonesia
AI summary Read the abstract
This is the first study to measure microplastic pollution in sediments across protected areas near Jakarta, Indonesia, including a wildlife reserve, a Ramsar wetland site, and a marine national park. Microplastics were found at all locations, with higher concentrations closer to human activity and during the dry season. The results suggest that even designated conservation areas are not spared from microplastic contamination.
