“…Polypropylene is the main material used to produce disposable masks (Selvaranjan et al, 2021). This is in accordance with the observations made by Rebia et al (2022), functional groups of three-layer mask waste were confirmed and analyzed using a Nicolet™ iS50 Fourier Transform Infra-Red Spectroscopy (FTIR) Spectrometer. Based on the results of the functional group analysis, the outer (L), middle (T), and inner (D) layer masks (Figure 2) are characterized by the typical absorption of polypropylene.…”

“…Figure 3. FTIR results on functional group analysis of disposable mask waste layers (Rebia et al, 2022) Polypropylene is a vinyl polymer in which each carbon atom is attached to a methyl group (-CH3) (Figure 4). Polypropylene is a type of plastic that is often used in various industries because it is very cheap, has a low density that makes it easy to print, and has excellent chemical resistance (Hisham, 2016).…”

At present, disposable masks have become a necessity and habit for the general public. This causes an increase in the volume of single-use mask waste generation. If disposable mask waste is not managed properly and correctly it can harm living things such as fauna and contains micro plastics which have the potential to be a source of pollution in the environment. This study aims to analyze the potential impact of household-scale disposable mask waste pollution in Cinere District. The method used in this research is statistics and literature study. The results showed that the average use of disposable face masks in Cinere District was 2 pieces/day with a weight of 3.54 grams and it was estimated that the people of Cinere District produced 76,494 disposable masks waste/day with an extrapolation of the potential impact of micro plastic pollution reaching 67.31 billion/day which will be released into the environment. This will be a heavy burden on the environment, therefore good cooperation is needed between the community and the government in managing disposable mask waste on a household scale in order to reduce and prevent pollution of disposable mask waste in the environment.

“…The middle layer medical mask was chosen because it is made of the strongest polypropylene layer, as opposed to the first and third layers, which are suitable for composite materials. It was known that the mask was made of polypropylene as the result of an FTIR investigation from the earlier study conducted by the researcher [13]. After being cut, the mask material was put into a grinder for a maximum of 10-15 grams to be smoothed evenly to produce reinforcement in the form of particles.…”

“…10% of polypropylene had the highest tensile strength compared to 30% and 50%, with 90-100 MPa, while the percentage of 50% of polypropylene fiber and epoxy in another study obtained 28 MPa of tensile strength [12]. The earlier studies also used waste from medical masks to calculate the mechanical properties of a thin layer of polypropylene sheet [13], [14]. On the other hand, there aren't many composite samples that have been investigated with the raw materials from medical mask waste.…”

Dengan maraknya penggunaan masker sekali pakai, maka limbah dari masker tersebut menjadi polemik di tengah masyarakat karena masker terbuat dari bahan yang sama dengan plastik yang tidak mudah terdegradasi. Oleh karenanya, perlu pengolahan limbah tersebut untuk menjadi produk baru salah satunya menjadi komposit. Penelitian ini bertujuan untuk menghasilkan komposit dari resin epoksi dan lapisan tengah masker medis untuk mengetahui bagaimana pengaruh penambahan fraksi volume bagian lapisan tengah masker medis terhadap kekuatan tarik dan mengetahui sifat, struktur, dan karakteristik pada komposit lapisan tengah masker medis. Karena komposit merupakan gabungan dua bahan atau lebih yang disusun untuk meningkatkan sifat mekanik bahan agar lebih unggul dan memiliki sifat yang tidak sama dengan sifat bahan aslinya. Pemanfaatan material komposit pada saat ini semakin berkembang, seiring berjalan dengan meningkatnya penggunaan bahan yang lebih unggul tersebut yang semakin meluas mulai dari yang sederhana seperti alat-alat rumah tangga sampai dalam bidang industri otomotif. Pengolahan masker medis terutama lapisan tengah masker medis pada penelitian ini berupa lembaran polipropilen yang telah disterilisasi dan dipotong-potong dicampur dengan resin epoksi sebagai fasa pengikat dengan perbandingan fraksi volume 1:3 pada sampel 1, 1:1 pada sampel 2 dan sedangkan sampel 3 adalah 3:1. Kemudian pengujian dilakukan secara fisik dan mekanik, yaitu pengamatan morfologi menggunakan Scanning Electron Microscope (SEM) serta uji kekuatan tarik. Berdasarkan hasil uji tarik bisa diamati rata-rata tegangan maksimum setiap volume serat polipropilen pada 25% sebesar 1,73 MPa, 50% sebesar 2,58 MPa serta 75% sebesar 19,64 MPa. Hasil tersebut dapat disimpulkan bahwa semakin besar persentase volume serat polipropilen yang berasal dari masker maka akan semakin besar pula nilai tegangan maksimum yang diperoleh. With the widespread use of disposable masks, the waste from these masks has become a polemic in the community because masks are made of the same material as plastic, which is not degradable. Therefore, it is necessary to process the waste to create new products. One of them is a composite. This study aims to produce a composite of epoxy resin and the middle layer of a medical mask to determine the effect of adding the volume fraction of the middle layer of a medical mask to the tensile strength and to determine the properties, structure, and characteristics of the composite middle layer of a medical mask. Because the composite is a combination of two or more materials that are arranged to improve the mechanical properties of the material, it is superior and has properties that are not the same as the properties of the original material. The use of composite materials is currently increasing, as is the use of these superior materials, which are becoming more widespread in applications ranging from simple household appliances to the automotive industry. Processing of medical masks, especially the middle layer of medical masks, was studied in the form of polypropylene sheets that had been sterilized and cut into pieces mixed with epoxy resin as the binding phase with a volume fraction ratio of 1:3 in sample 1, a ratio of 1:1 in sample 2, and a 3:1 ratio in sample 3. Then the tests were carried out physically and mechanically, namely morphological observations using a scanning electron microscope (SEM) and tensile strength tests. Based on the results of the tensile test, it can be observed that the average maximum stress for each volume of polypropylene fiber is 1.73 MPa at 25%, 2.58 MPa at 50%, and 19.64 MPa at 75%. These results indicate that the greater the volume percentage of polypropylene fiber originating from the mask, the greater the maximum stress value obtained.
