“…Soft sediments containing high percentages of clay and silt can contain more debris concurrently than hard sediments such as gravel and rocks (Watters et al, 2010). Therefore, the presence of clay and silt causes the sediment to become a stronger trap against MPs (Wahyuningsih et al, 2018). However, according to these studies, silt was expected to have a relationship with MPs equal or greater than clay, but it results less relevant than clay.…”

“…Mikroplastik jenis film ditemukan dengan bentuk yang tidak beraturan, tipis seperti lembaran atau pecahan plastik. Mikroplastik jenis film berasal dari proses fragmentasi plastik kemasan maupun kantong plastik yang berwarna transparan (Wahyuningsih, 2018). Bentuk pelet ditemukan paling sedikit diduga karena sumber cemaran mikroplastik dari pelet tidak terlalu banyak.…”

Microplastics are small plastic particles that have the characteristics of easily accumulating in seawater and sediments with a diameter of less than 5 mm. The presence of microplastics in seawater and sediments may have a chain impact on marine ecosystems and humans. The purpose of this study was to determine the characteristics of microplastics in sediment and seawater in the Wulan River Estuary, Demak. Sediment and seawater samples were taken by purposive sampling at five different stations in line with the river mouth on 20 May 2021. Visual identification and counting of microplastics using a microscope, and FTIR (Fourier transform infrared) test. The highest abundance of microplastics was found in Station 2 sediment (400 particles.Kg-1) and Station 1 seawater (99 particles.L-1) which is the end of the Wulan river flow. The diversity of microplastic characteristics in the form of fragments, fibers, pellets and films, the most abundance was fragments of particles in sediment and seawater samples. The color of the microplastic particles is predominantly black and blue, with lesser number of brown, white, red, green, yellow and purple. The microplastic particle size range was found between 1.00-259.06 m. Microplastic pollutants are nitrile, nylon and PTFE (Polytetrafluoroethylene) plastics. The results of this study reveal the sources of anthropogenic pollution in the study area which are not only caused by human activities on land but also from the movement of water in the marine environment. Mikroplastik adalah partikel plastik kecil yang memiliki karakteristik mudah terakumulasi pada air laut laut dan sedimen dengan ukuran diameter kurang dari 5 mm. Keberadaan mikroplastik pada air laut laut dan sedimen dapat memberikan dampak berantai terhadap ekosistem perair lautan dan manusia. Tujuan dari penelitian ini adalah untuk mengetahui karakteristik mikroplastik pada sedimen dan air laut di Muara Sungai Wulan, Demak. Sampel sedimen dan air laut diambil dengan purpossive sampling di lima stasiun yang berbeda segaris dengan muara sungai pada tanggal 20 Mei 2021. Identifikasi dan penghitungan mikroplastik secara visual menggunakan mikroskop, dan uji FTIR (Fourier transform infrared). Kelimpahan mikroplastik tertinggi ditemukan pada sedimen Stasiun 2 (400 partikel.Kg-1) dan air laut Stasiun 1 (99 partikel.L-1) yang merupakan akhir dari aliran sungai Wulan. Keragaman karakteristik mikroplastik yang berupa fragment, fiber, pellet dan film, partikel fragmen terbanyak di sample sedimen dan air laut. Warna partikel mikroplastik didominasi hitam dan biru, dengan warna coklat, putih, merah, hijau, kuning dan ungu yang lebih sedikit. Rentang ukuran partikel mikroplastik yang ditemukan antara 1,00-259,06 µm. Polutan mikroplastik berjenis plastik nitrile, nylon dan PTFE (Polytetrafluoroethylene). Hasil penelitian ini mengungkapkan sumber polusi antropogenik di daerah penelitian yang tidak hanya disebabkan oleh aktivitas manusia di darat tetapi juga dari pergerakan air di lingkungan laut.

“…Plastics on the beach can be defined based on their sizes: macro-, meso-, and micro-plastics. Macroplastics are plastic debris that have sizes more than 20 mm (Noik and Tuah, 2015;Wahyuningsih et al, 2018;Napper and Thompson, 2019) or 25 mm (Lee et al, 2013;Blettler et al, 2017;Bancin et al, 2019), and easy to spot due to their clear visibility, hence, easy to remove (Jeyasanta et al, 2020). Macroplastics can be broken down into small fractions due to various factors, such as, the weathering and UV radiation processes (Wagner et al, 2014).…”

Highlight Research The present of microplastics is more than macroplastics on the Pasir Pandak Beach The existence of huge amount of smaller microplastics (<0.50 mm) were observed on this beach sediment Types of macroplastics found are fragment, foam, and fiber; while microplastics are fiber, filament, fragment, and foam The main polymers found are HDPE, PES, PP, and PS Clean Coast Index indicated Pasir Pandak Beach as an extremely dirty beach Abstract Pasir Pandak Beach is close to human settlements, resorts, and food stalls. It becomes a place for gathering of beachgoers especially during weekend. As a result, the beach became polluted with rubbish, particularly plastics (e.g., macro- and micro-plastics). Hence, this study was done to determine the occurrence of macro- and micro-plastics on the Pasir Pandak Beach, Kuching, Sarawak, Malaysia. Transect quadrat was used during the samples collection on the beach. The samples were then undergone the wet peroxide oxidation, filtering and classifying under dissecting microscope. Macroplastics were isolated for ATR-FTIR and SEM analyses, while microplastics were separated according to their sizes, colors, and types. Approximately 101.70 items/m2 of macro-plastics and 1084 items/m2 of micro-plastics were found in this study. Clean Coast Index (CCI) was also estimated and the calculated CCI value obtained was >20, which indicated as extremely dirty beach. Fragments of carpet/canvas/mat and hardware crate/item were the most abundance macroplastics found, followed by plastic ropes/fishing lines and bottle caps. HDPE, PES, PP, and PS were the main identified polymers. Fibers, filaments, fragments, and foams were identified for micro- and macro-plastics. Microplastics with smaller sizes of 0.25-0.50 mm were available abundantly and they comprise 63.47 % of the total microplastics found. Clear/white, black, and blue were the main colors for microplastics. SEM images presented that those adhering particles, grooves, pits, fractures, and flakes were the common patterns of degradation. No relationship was apparent between macro- and micro-plastics at each station. The abundance of macro- and micro-plastics showed that they were mainly controlled by the land-based input. As Pasir Pandak beach is busy with local communities and beachgoers, the presence of macro- and micro-plastics on the beach posing a severe threat for marine environment, thus further studies on the behavior of this emerging pollutant from beach to the seas are necessary.
