Abstract
Mikroplastik didefinisikan sebagai partikel plastik berukuran <5 mm. Mikroplastik ditemukan di berbagai bagian lingkungan salah satunya udara. Partikel mikroplastik dangan ringan dan kecil sehingga mudah terbang dan terhirup oleh manusia. Ketika terhirup mikroplastik dapat masuk ke sistem pernafasan dan terakumulasi di tubuh sehingga memberikan dampak pada kesehatan manusia. Sumber mikroplastik berasal dari perabotan rumah tangga, peralatan kebersihan, tekstil dan lainnya. Pelepasan mikroplastik dari pakaian atau tekstil ke udara terjadi ketika digunakan dan dicuci. Oleh karena itu, perlu dilakukan penelitian dengan tujuan menentukan kuantitas, bentuk, dan jenis mikroplastik serta menentukan pengaruh operasional usaha laundry terhadap kuantitas mikroplastik pada udara dalam ruang. Penelitian dilakukan pada empat usaha laundry yang terdiri dari Home Laundry dan Coin Laundry. Sampel diambil dua kali dalam sehari selama dua hari. Debu dikumpulkan menggunakan vacuum cleaner selama 10 menit dengan ketinggian 1,2 m. Debu yang terkumpul pada vacuum bag dilepaskan menggunakan aquades lalu di pre-treatment dengan ZnCl2. Selanjutnya sampel dianalisis secara visual menggunakan mikroskop digital. Setelah itu, sampel dianalisis dengan spektrofotometri Fourier Transform Infrared (FTIR) untuk menentukan gugus kimianya. Hasil pengamatan mikroskop menunjukkan bahwa Laundry A memiliki kuantitas 326 dan 325 partikel sebelum beroperasi serta 468 dan 525 partikel saat beroperasi. Laundry B memiliki kuantitas 424 dan 336 partikel sebelum beroperasi serta 549 dan 580 partikel saat beroperasi. Laundry C memiliki kuantitas 391 dan 379 partikel sebelum beroperasi serta 581 dan 651 partikel saat beroperasi. Laundry D memiliki kuantitas 343 dan 349 partikel sebelum beroperasi serta 512 dan 598 partikel saat beroperasi. Bentuk mikroplastik yang terdapat pada keempat lokasi penelitian dominan berbentuk fiber. Pengaruh operasional laundry terhadap mikroplastik di udara dalam ruang ditentukan dari uji T dependen. Hasil uji T menunjukkan terdapat perbedaaan yang signifikan antara kuantitas sebelum beroperasi dan saat beroperasi dengan rata – rata peningkatan 198,87 partikel. Beberapa jenis mikroplastik yang ditemukan yaitu berupa cellophane, polipropilena (PP), dan polietilen tereftalat (PET).

Microplastics are defined as plastic particles measuring <5 mm. Microplastics are found in various parts of the environment, one of which is the air. Microplastic particles are light and small so they can easily fly and be inhaled by humans. When inhaled, microplastics can enter the respiratory system and accumulate in the body, thus having an impact on human health. Sources of microplastics come from household furniture, cleaning equipment, textiles and others. The release of microplastics from clothing or textiles into the air occurs when they are used and washed. Therefore, it is necessary to carry out research with the aim of determining the quantity, shape and type of microplastics and determining the influence of laundry business operations on the quantity of microplastics in indoor air. Research was conducted on four laundry businesses consisting of Home Laundry and Coin Laundry. Samples were taken twice a day for two days. Dust was collected using a vacuum cleaner for 10 minutes at a height of 1.2 m. The dust collected in the vacuum bag is released using distilled water and then pre-treated with ZnCl2. Next, the samples were analyzed visually using a digital microscope. After that, the sample was analyzed using Fourier Transform Infrared (FTIR) spectrophotometry to determine the chemical group. Microscope observation results show that Laundry A has a quantity of 326 and 325 particles before operating and 468 and 525 particles when operating. Laundry B had quantities of 424 and 336 particles before operating and 549 and 580 particles when operating. Laundry C had quantities of 391 and 379 particles before operating and 581 and 651 particles when operating. Laundry D had quantities of 343 and 349 particles before operating and 512 and 598 particles when operating. The form of microplastics found in the four research locations is predominantly fiber. The effect of laundry operations on microplastics in indoor air was determined from the dependent T test. The T test results show that there is a significant difference between the quantity before operation and during operation with an average increase of 198.87 particles. Several types of microplastics found were cellophane, polypropylene (PP), and polyethylene terephthalate (PET).
