“…After the filtration, the samples were filtered using Whatman GF/C paper with the assistance of the vacuum filter. Whatman GF/C paper is used because it has pores measuring 1.2 µm; hence, it is very appropriate if used to filter microplastics (Wulandari et al, 2021). After the water sample was drained, the filter paper was transferred to a petri dish and placed in an oven at 70 C for 1 h. The filter paper was marked with a line into eight sections to facilitate identification.…”

Microplastics (MPs) significantly damage the environment and human health, leading to a growing global concern. MPs have been detected not only in the natural environment but also in the drinking water treatment process. One of the configurations of the drinking water treatment unit is filtration. Only a few research studies have been published on microplastic removal in the water system. This study was conducted to determine the performance of a rapid sand filter (RSF) in removing microplastics in water with a variation in the effective size (ES) of silica sand and microplastic size. In this study, microplastics are artificially made with size variations of < 400 μm and >400 μm. The filtering uses two variations in the adequate size (ES) of silica sand, namely 0.4 mm and 0.7 mm. At the same time, anthracite is only a control variable with ES = 0.69 with a flow speed of 4 m / h and an observation time of 30, 60, 90, and 120 minutes. The results show that the filter media ES 0.4 has the highest efficiency values of 91.30% for the microplastic size MPs <400 µm and 95.80 % for the larger microplastic >400 µm. In addition, the average percentage removal of ES 0.7 mm was 77.24 % for the size of MPs <400 µm and 95.77% for the size of Mps >400 µm. Gaining insight into the mechanisms involved in removing microplastics from drinking water is essential for developing more effective techniques for eliminating them.

Tingginya aktivitas masyarakat mengakibatkan terjadinya degradasi sumberdaya perairan di sekitar Perairan Teluk Ambon. Munculnya bahan pencemar mikroplastik merupakan hasil dari semakin meningkatnya penduduk di Kota Ambon dan pola konsumsi bahan kemasan plastik yang tidak dapat dihindari. Tujuan dari penelitian ini yaitu:Â 1) menganalisis keberadaan mikroplastik berdasarkan bentuk pada ikan budidaya di Perairan Teluk Ambon, dan 2) menganalisis kelimpahan mikroplastik pada ikan budidaya di Perairan Teluk Ambon.Â Penelitian ini dilakukan pada Juli-September 2021 di perairan Teluk Ambon khususnya pada beberapa tempat budidaya ikan. Pengambilan sampel ikan budidaya yang siap dipanen dan dikonsumsi, dilakukan dengan menggunakan metodeÂ purposive sampling. Analisa mikroplastik dilakukan di Laboratorium Mikroplastik PPLD LIPI Ambon. Sampel yang diperoleh didestruksi secara peroksida, kemudian ditambahkan larutan NaCl jenuh. Selanjutnya sampel diamati dengan menggunakan mikroskop dan didokumentasikan serta ditampilkan dalam bentuk gambar/grafik untuk dibahas selanjutnya. Berdasarkan hasil penelitian diperoleh empat bentuk partikel mikroplastik yaitu fiber, fragmen, film dan granul. Jumlah partikel mikroplastik pada kolom air secara keseluruhan sebesar 2.724 partikel. Mikroplastik bentuk fiber memiliki jumlah partikel tertinggi yaitu sebesar 2.208 partikel dengan kelimpahan sebesar 55,2 partikel/ltr. Secara keseluruhan, jumlah partikel mikroplastik pada ikan budidaya sebesar 1.489 partikel. Mikroplastik bentuk fiber memiliki jumlah partikel tertinggi yaitu sebesar 831 partikel dengan kelimpahan sebesar 55,4 partikel/ind. Dapat dikatakan bahwa ikan budidaya pada Perairan Teluk Ambon telah dicemari oleh mikroplastik.
