Mikroplastik pada Terumbu Karang di Pulau Panjang Jepara
Summary
This Indonesian study examined microplastic contamination in coral reef ecosystems around Panjang Island in Jepara. The findings document plastic pollution in a reef system affected by tourism and waste disposal from visiting communities, raising concerns about plastic impacts on sensitive marine habitats.
Ekosistem terumbu karang di Pulau Panjang Jepara menjadi salah satu daya tarik bagi wisatawan baik dalam kota maupun dari luar kota. Kegiatan pengunjung yang datang ke pulau ini mempengaruhi kondisi terumbu karang yang ada akibat meningkatnya pembuangan sampah termasuk plastik. Plastik tersebut terdegradasi dalam waktu lama menjadi mikroplastik. Penelitian ini dilakukan pada bulan Agustus 2022. Metode penelitian mengacu kepada studi survey pada daerah reef flat pulau. Teknik pengambilan sampel menggunakan purposive sampling dengan 2 kali pengulangan di setiap lokasi pengambilan dengan pengambilan sampel karang, sampel air dan sampel sedimen. Sampel yang didapatkan dilakukan ekstraksi mikroplastik, kemudian dilakukan analisis mikroplastik menggunakan mikroskop, selanjutnya dilakukan identifikasi mikroplastik dan analisis data. Hasil penelitian menunjukkan bahwa jenis mikroplastik yang ditemukan pada karang, air dan sedimen adalah jenis fiber, fragmen, film dan pellet. Kelimpahan mikroplastik tertinggi pada karang dengan 1,35 partikel/gr dan terendah dengan 0,42 partikel/gr. Kelimpahan mikroplastik tertinggi pada air dengan 0,35 partikel/mL dan terendah dengan 0,05 partikel/mL. Kelimpahan mikroplastik tertinggi pada sedimen dengan 0,38 partikel/gr dan terendah dengan 0,17 partikel/gr.

First Evidence of Microplastics Presence in Coralsof Jepara Coastal Waters, Java Sea: A ComparisonAmong Habitats Receiving Different Degreesof Sedimentations
Researchers found microplastics inside coral tissues collected from Jepara coastal waters in the Java Sea — one of the first such reports for Indonesian coral reefs. Corals in areas with higher sedimentation contained more microplastics, suggesting sediment transport plays a role in microplastic accumulation. The findings raise concerns about coral reef health under combined microplastic and sedimentation stress.
Microplastics as a sedimentary component in reef systems: A case study from the Java Sea
Researchers investigated microplastic distribution in sediments from two tropical atoll reef platforms in Indonesia. The study found that microplastics are a component of reef sediments, with distribution patterns influenced by reef geomorphology and hydrodynamic processes, highlighting the need to better understand how microplastics accumulate in coral reef systems and their potential impacts on reef health.
Mikroplastik Pada Sedimen di Zona Pemukiman, Zona Perlindungan Bahari dan Zona Pemanfaatan Darat Kepulauan Karimunjawa, Jepara
This Indonesian study investigated microplastic types and abundances in sediments across different zones of the Karimunjawa National Park, comparing residential, marine protected, and buffer zones. The results show that even protected marine areas in Indonesia are not immune to microplastic contamination.
