“…Hal itu merupakan imbas dari adanya pelarangan penggunaan kantong plastik serta kebijakan plastik berbayar (Republika, 2019). Lebih lanjut, selain larangan penggunaan kantong plastik, penggunaan plastik ramah lingkungan oxobiodegradable seperti plastik oxium diharapkan juga mampu mengurangi jumlah sampah plastik di lingkungan, terutama di wilayah perairan laut (Asriza and Pitulima, 2017).…”

“…Plastik oxobiodegradable merupakan polimer sintetis yang berbahan dasar polietilen dengan penambahan zat kromofor atau aditif oksidan ke rantai polimer sekitar 1-5 % aditif dari berat molekul polimernya sesuai standar ASTM D-5208 , salah satu contoh bahan aditif ini disebut sebagai oxium (Aldas et al, 2018). Penambahan kromofor ini diharapkan akan mampu meningkatkan kemampuan degradasi pada plastik, yang artinya dapat terurai dengan alami dalam waktu relatif cepat, sehingga tidak mencemari lingkungan (Asriza and Pitulima, 2017). Tetapi, fakta lain ditunjukkan dari penelitian Aldas et al, (2018) dan Campanale et al, (2020) yang menunjukkan bahwa zat kromofor yang ditambahkan dalam plastik oxo-degradable termasuk dalam bahan aditif yang berbahaya bagi lingkungan, hal ini disebabkan cepatnya laju degradasi plastic oxo degradable seiring dengan peningkatan kemampuannya dalam melepas bahan aditif yang bersifat toksik bagi lingkungan seperti .…”

Salah satu cara yang digunakan di Indonesia dalam menanggulangi berlimpahnya jumlah sampah plastik di lingkungan perairan adalah dengan menggantikan kantong plastik berbahan polimer polietilen (PE) dengan plastik oxodegradable yang disebut oxium. Penelitian ini dilakukan dengan tujuan untuk melihat pengaruh mikroplastik polietilen jenis HDPE (High Density Polyethylene) dengan plastic oxodegradable oxium. Penelitian dilakukan dengan menggunakan mikroalga Tetraselmis chuii sebagai mikroorganisme yang akan mendapat perlakuan mikroplastik dengan konsentrasi yang berbeda. Dari Hasil pengukuran optical density untuk menentukan laju pertumbuhan mikroalga Tetraselmis Chuii menunjukkan bahwa laju pertumbuhan Tetraselmis dengan perlakuan mikroplastik polietilen mengalami penurunan yang signifikan dibandingkan dengan mikroplastik oxium. Konsentrasi mikroplastik ikut berperan dalam menentukan laju pertumbuhan Tetraselmis chuii di mana pada perlakuan mikroplastik oxium terjadi penurunan hingga 37,66% pada konsentrasi mikroplastik 300mg/500mL dan 81,70% pada perlakuan mikroplastik polietilen dengan konsentrasi 200mg/500mL. Mikroplastik polietilen dan oxium memberikan dampak negatif pada organisme tingkat rendah disebabkan oleh kemampuannya dalam melepas bahan aditif yang bersifat toksik sehingga diperlukan solusi yang lebih baik untuk menggantikan fungsi plastik dengan bahan yang lebih ramah bagi lingkungan hidup. ABSTRACTOne of the methods used in Indonesia in tackling the abundance of plastic waste in the aquatic environment is to replace plastic bags made of polyethylene (PE) polymer with oxodegradable plastic called oxium. This research was conducted with the aim of examining the effect of HDPE (High Density Polyethylene) microplastic polyethylene with oxodegradable oxium plastic. The research was conducted using the microalgae Tetraselmis chuii as microorganisms that will receive microplastic treatment with different concentrations. From the results of optical density measurements to determine the growth rate of Tetraselmis chuii microalgae, it was shown that the growth rate of Tetraselmis with polyethylene microplastics treatment decreased significantly compared to oxium microplastics. The concentration of microplastics played a role in determining the growth rate of Tetraselmis chuii where in the oxium microplastic treatment there was a decrease of up to 37.66% at the microplastic concentration of 300mg/500mL and 81.70% at the polyethylene microplastic treatment with a concentration of 200mg/500mL. Polyethylene and oxyum microplastics have a negative impact on low-level organisms due to their ability to release toxic additives so that better solutions are needed to replace the function of plastics with materials that are more environmentally friendly.

“…), bisphenol A, and phthalate (Campanale et al 2020). This latter chemical is added during the plastic manufacturing process to boost the plastic's tensile strength, which affects the material's capacity to degrade (Asriza and Pitulima 2017). Plastic breakdown products in microplastics and the release of chemical compounds will have a negative impact on microorganism in the aquatic system (Koelmans et al 2013).…”

The COVID-19 pandemic has mandated people to use medical masks to protect the public. However the improper management of disposable mask waste has led to the increase of marine pollution, in terms of water quality, and the decline in aquatic microorganisms. The aim of this research was to investigate the impact of disposable mask waste on fresh water and microalgae biomass quality. Disposable masks (untreated or treated with Enterococcus faecalis ) were placed in 10-L glass reactors containing fresh water or water containing algal Chlorella sp. and its growth supplements ( Chlorella medium) (four 10-L reactors in total) and kept in controlled conditions for 3 months. Water and biomass yield quality were evaluated using water quality analysis, spectroscopy, scanning electron microscopy (SEM), and proximate lipid and protein analysis. Disposable masks, incubated in either fresh water or Chlorella medium, affected several water quality parameters such as chemical oxygen demand (COD), biological oxygen demand (BOD), dissolved oxygen (DO), and pH. Microplastic identification revealed that some fibers were present in the water following a 100-day treatment process. Fourier transform–infrared spectroscopy (FTIR) analysis was used to determine the change in important, organic functional groups and highlighted the disappearance of a peak at 1530 cm −1 corresponding to the primary protein (C–N) and the appearance of new peaks at 1651 cm −1 and 1270 cm −1 corresponding to methyl alcohol (CH 2 OH) and ketone (C = O), respectively. This indicated the detrimental effect of disposable mask fragmentation on the biomass quality. The SEM investigation has shown a damage to the surface membrane of Chlorella sp. cells. Altogether, disposable masks decreased the water quality and damaged microalgae by inhibiting their growth. Therefore, the disposable mask contaminated by various microbes, after being used by a human, may be one of the most dangerous hazards to the environment.
