Abstract

Penggunaan masker sekali pakai terkait pandemi Covid-19 di satu sisi melindungi pemakainya dari virus, namun di lain sisi menimbulkan permasalahan terhadap lingkungan. Oleh karena itu, dilakukan sejumlah upaya daur ulang limbah masker, salah satunya dengan mengolahnya menjadi material baru, seperti produk interior, bijih plastik, dan adsorben pada limbah cair industri laundry. Penelitian ini bertujuan untuk menganalisis sifat mekanik lembaran plastik hasil pengolahan limbah masker sekali pakai jenis masker medis tiga lapis (3 ply) dengan variasi berat. Metode yang digunakan adalah tekan panas (hot press) dengan variasi berat 10 gr, 20 gr, 30 gr, 40 gr, 50 gr, dan 60 gr. Pengujian yang dilakukan adalah uji tarik, mulur, dan ketebalan sampel. Hasil dari penelitian menunjukkan bahwa pertambahan berat meningkatkan kekuatan tarik, mulur, dan ketebalan. Sampel dengan berat 10 gr memiliki kekuatan tarik, mulur, dan ketebalan terendah, yaitu masing-masing 0,001 MPa, 0,311%, dan 0,143 mm. Sedangkan sampel dengan berat 60 gr memiliki kekuatan tarik, mulur, dan ketebalan tertinggi, yaitu masing-masing 0,023 MPa, 1,155%, dan 0,837 mm.Kata kunci: mulur, ketebalan, kekuatan tarik, limbah masker, tekan panas

Abstract

Based on observations and interviews conducted at SMK Muhammadiyah Gamping Sleman, there areproblems that can be solved through the community service activities, that is waste of leaves which have potential to become textile products. This can also be an alternative for developing skills and a synergy with school subjects whichecoprinting has never been taught at SMK Muhammadiyah Gamping Sleman. The methods used include: 1) Ecoprint training using steaming and pounding techniques; 2) Creative products-making; and 3) Digital marketing training in the field of fashion. The results of these activities areboth students and teachers are able tomake ecoprint fabric, process it into creative products, and undertstand digital marketing. Furthermore, the results of a questionnaireconducted byparticipants showed that there are beneficial values, both for individuals and school subjects, as well as an increase in ecoprint knowledge. Thus, it can be concluded that this community service is on target and achieves its goals

Abstract

Pineapple leaf fiber is a natural fiber that remains underutilized despite its potential. This fiber is composed of bundles bound by pectin, hemicellulose, and lignin, which must be removed through a degumming process. This study aims to investigate the effects of NaOH concentration and processing temperature variations on the characteristics of pineapple leaf fibers, including mass reduction, tensile strength, and elongation. The experimental method involved alkali treatment using NaOH solutions with concentrations of 1%, 3%, 5%, 7%, and 10%, at three temperature variations of 60°C, 80°C, and 100°C. Each sample was weighed to determine mass reduction, followed by tensile strength and elongation testing. The experimental data were analyzed using R-statistics to evaluate the significance of differences among treatments. The results showed that higher NaOH concentrations and temperatures lead to greater mass reduction, with the highest value of 31.92% obtained at 100°C and 10% NaOH. However, this condition also caused a decrease in tensile strength to below 10 cN/tex and an increase in elongation to more than 6%. Statistical analysis revealed that differences in treatments were not significant at 60oC (p > 0,9), but become significant at 80-100oC (p < 0,05). The study concludes that insufficiently strong treatments are ineffective, while excessively strong treatments may cause cellulose degradation, leading to decreased mechanical properties of the fibers.
