Kota Semarang merupakan ibukota Provinsi Jawa Tengah serta menjadi pusat bisnis, ekonomi, pendidikan, dan berbagai kegiatan sosial. Hal ini menyebabkan kota ini memiliki produksi sampah yang besar. Sampah plastik, yang merupakan salah satu jenis sampah yang sering ditemukan dapat mengalami degradasi menjadi potongan plastik lebih kecil yang dinamakan mikroplastik. Perairan Semarang dipilih sebagai lokasi penelitian karena Kota Semarang merupakan daerah dengan aktivitas manusia yang tinggi dan menghasilkan banyak limbah plastik yang dapat mengendap dalam sedimen laut. Penelitian ini dilakukan untuk mengetahui pencemaran mikroplastik pada sedimen di Perairan Semarang. Pengambilan sampel dilakukan sebanyak 4 kali yaitu pada bulan April, Mei, Agustus, dan September 2021 secara purposive sampling menggunakan alat sediment grab di tiga titik berbeda yaitu muara, pantai, dan laut. Sedimen sebanyak 50 gram direndam dalam 100 ml larutan ZnCl2 selama 24 jam. Partikel mikroplastik yang mengambang dipisahkan kemudian direndam dalam 50 ml larutan H2O2 30% selama 24 jam dan disaring dengan menggunakan kertas saring MN (Macherey Nagel). Mikroplastik yang diperoleh diamati menggunakan mikroskop dan dianalisis bentuk, warna dan kelimpahannya. Hasil penelitian menunjukkan bahwa warna dan bentuk mikroplastik yang diperoleh yaitu, berdasarkan bentuknya antara lain fragmen, pelet, film, dan fiber, berdasarkan warnanya antara lain hitam, coklat, merah, kuning, putih, hijau, dan ungu. Kelimpahan mikroplastik pada Bulan April sebanyak 2.577 partikel/kg, Bulan Mei sebanyak 2.058 partikel/kg, Bulan Agustus sebanyak 1.858 partikel/kg, dan Bulan September sebanyak 2.011 partikel/kg. Semarang City is the capital city of Central Java Province as well as being the center of business, economy, education, and various social activities. Plastic waste, which is one type of waste that is often found, can experience degradation into smaller pieces of plastic called microplastics. Semarang Waters were chosen as the research location because Semarang City is an area with high human activity and produces a lot of plastic waste which will later settle in marine sediments. This research was conducted to determine microplastic pollution in sediments in Semarang Waters. Sampling was carried out 4 times in April, May, August, and September 2021 by a purposive sampling using a sediment grab tool at three different points, namely the estuary, beach, and sea. From each sample 50 grams of sediment was immersed in 100 ml of ZnCl2 solution for 24 hours. The floating microplastic particles were separated and then immersed in 50 ml 30% H2O2 solution for 24 hours and filtered using MN (Macherey Nagel) filter paper. The obtained microplastics were observed using a microscope and analyzed for shape, color and abundance. The results showed that these are microplastics in the shape of fragments, pellets, films, and fibers, with the colors of black, brown, red, yellow, white, green, and purple. The abundance of microplastics in April was 2.577 particles kg-1, in May 2.058 particles kg-1, in August 1.858 particles kg-1, and in September 2.011 particles kg-1.

“…The density separation process proceeded using a mixture of saturated NaCl solutions of 150 ml each. It was then manually stirred to have no lumps of sample for 1 minute (Ridlo et al, 2020) and then allowed to stand for 5 minutes to form a precipitate layer. The precipitated layer sediment sample was taken as part of the surfactant, added to 15 ml of H2O2 solution, and incubated for 24 hours (Zhao et al, 2018).…”

Microplastics are a form of new pollution that the Indonesian people are not aware of. The factors for the entry of microplastics into pond waters are water sources, anthropogenic activities, and pond cleanliness. The purpose of this study was to determine the abundance of microplastics, the color and shape of microplastics, and the types of microplastic polymers found in sediment, water, and the digestive tract of milkfish (Chanos chanos) in Sidoarjo ponds. The average abundance of microplastics in sediment samples obtained from semi-intensive ponds is 300 particles per 50 grams, while the sediment samples from traditional ponds are 613 particles per 50 grams. The average abundance of microplastics in the semi-intensive pond water samples was 2.1 particles per 20 liters and in traditional ponds was 2.3 particles per 20 liters. The average abundance of microplastics in the milkfish (Chanos chanos) samples from the Semi-Intensive Pond was as many as 6 particles per tail, while the Traditional Pond had 9.5 particles per tail. In this study, four colors of microplastics were found, namely blue, black, red, and transparent, while the microplastics obtained were fiber, fragment, and filament. The types of microplastic polymers encountered in this study were dominated by polyamide or nylon polymers. In sediment samples from both ponds, we found the presence of Polyamide or Nylon polymers, namely Polystyrene and Polyamide or Nylon, and in the digestive tract of milkfish (Chanos chanos), namely Polyamide or Nylon.

Di wilayah Jawa Tengah, khususnya pantai utara, penelitian mikroplastik masih sedikit dilakukan, dan sebagian besar hanya melakukan pengamatan di air laut atau di sedimen saja.…”

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.
