Identifikasi Sampah Laut pada Ekosistem Mangrove di Batukaras Kabupaten Pangandaran, Jawa Barat
Summary
This Indonesian study identified and categorized marine litter trapped in mangrove roots in West Java, finding predominantly plastic items. Mangroves can capture plastic debris from coastal waters, acting as both sinks and potential sources of microplastics as trapped items slowly degrade.
Penelitian ini dilaksanakan di Kabupaten Pangandaran yaitu di Batukaras, pada bulan Maret – April 2022. Penelitian bertujuan untuk mengetahui komposisi sampah laut apa saja yang dapat terperangkap pada akar mangrove Avicennia, komposisi sampah laut apa saja yang masih dapat berpindah setelah masuk ke ekosistem Mangrove dan kemampuan akar mangrove Avicennia dalam memerangkap sampah laut. Metode yang digunakan yaitu metode Transek garis atau Line Transect. Hasil yang diperoleh dari riset ini yaitu sampah laut yang ditemukan terdiri dari 11 jenis sampah dengan 3 kategori, yaitu kategori plastik dan karet, kaca, serta pakaian dan turunannya. Jumlah total sampah yang ditemukan sebanyak 203 potongan sampah dengan berat 1986 g. Kepadatan sampah yang ditemukan yaitu 8,24 potongan/m2, dominan sampah laut yang ditemukan yaitu kategori plastik dan karet. Komposisi sampah laut yang terperangkap dan berpindah secara keseluruhan berjumlah 203 potongan sampah, sebanyak 31,03% merupakan sampah laut yang terperangkap pada akar mangrove Avicennia dan sisanya 68,97% merupakan sampah yang dapat berpindah. Karakteristik sampah yang terperangkap pada akar mangrove Avicennia didominasi oleh kategori plastik dan karet dengan ukuran yang panjang. Hubungan keterperangkapan sampah laut pada akar mangrove Avicennia setelah dilakukan analisis korelasi, hasil yang diperoleh yaitu r = 0,6892, maka hubungan tersebut termasuk kedalam kategori kuat. Jadi semakin padat akar mangrove maka kepadatan sampah yang diperoleh akan meningkat, kemampuan akar dalam memerangkap sampah pun akan semakin baik. This research was conducted in Pangandaran Regency, namely in Batukaras, from March to April 2022. The research aims to determine the composition of marine debris that can be trapped in the roots of the Avicennia mangroves, the composition of marine debris that can still move after entering the mangrove ecosystem, and the ability of Avicennia mangrove roots in trapping marine debris. The method used is the Line Transect method. The results obtained from this research were that the marine debris found consisted of 11 types of waste with 3 categories, namely plastic and rubber, glass, and clothing, and their derivatives. The total amount of waste found was 203 pieces of waste weighing 1986 g. The density of the waste found was 8,24 pieces/m2, and the dominant marine debris found was the category of plastic and rubber. The total composition of trapped and displaced marine debris is 203 pieces of waste, 31,03% of which is marine debris trapped in the roots of the Avicennia mangroves and the remaining 68,97% is a movable waste. Trash characteristics trapped in Avicennia mangrove roots are dominated by plastic and rubber categories with long sizes. The correlation between marine debris entrapment in Avicennia mangrove roots after correlation analysis was carried out, the results obtained were r = 0,6892, so the relationship was included in the strong category. So the denser the mangrove roots, the density of the waste obtained will increase, and the ability of the roots to trap garbage will be even better.

Mangroves as unique but understudied traps for anthropogenic marine debris: A review of present information and the way forward
This review examined mangroves as understudied traps for anthropogenic marine debris, noting that 18 of the top 20 plastic-emitting rivers are associated with mangrove coastlines. Mangroves efficiently accumulate debris through their dense root structures, yet are rarely included in coastal plastic monitoring programs.
Identification of marine debris at Avicennia mangrove root in Pangandaran Beach, West Java
This study investigated marine debris trapped by Avicennia mangrove roots at Pangandaran Beach, Indonesia, examining how root structure affects debris capture. Mangrove forests act as natural filters for marine plastic debris, and understanding their trapping efficiency is important for assessing their role in coastal plastic pollution dynamics.
Impact of mangrove forest structure and landscape on macroplastics capture
Researchers surveyed macroplastic accumulation across seven mangrove forests in the Philippines, finding 1.1 items per square meter on average with the highest abundance at landward zones and near river mouths. Mangrove biomass and root structure were positively correlated with plastic capture, confirming that mangrove structural complexity enhances their ability to trap land-derived plastic litter.
