Abstract

Pandemi Covid-19 membawa dampak cukup besar bagi lingkungan, diantaranya adalah meningkatnya jumlah limbah masker sekali pakai. Limbah masker sekali pakai memiliki kandungan serat plastik yang membutuhkan waktu cukup lama untuk terurai di lingkungan. Tujuan penelitian ini untuk mengetahui pengaruh komposisi campuran limbah masker terhadap berat dan kuat tekan paving block, dan kesesuaian paving block dengan standar SNI 03-06910-1996. Pembuatan paving block diawali dengan pencucian dan penjemuran masker di bawah sinar matahari, lalu masker dicacah menjadi berukuran kecil. Selanjutnya masker dicampur dengan semen dan pasir dengan variasi komposisi A (1M:1S:5P), B (2M:1S:4P), C (3M:1S:3P), dan dicetak dengan ukuran 20cmx10cmx6cm. Setelah dilakukan perawatan selama 28 hari, diuji ke laboratorium. Data hasil pengujian dianalisis secara deskriptif dan analitik menggunakan Manova. Hasil pengujian menunjukkan bahwa rata-rata berat dan kuat tekan variasi A, B dan C secara berturut-turut adalah 2.77 kg dan 9.10 MPa; 2.64 kg dan 9.10 MPa; 2.29 kg dan 6.68 MPa. Dari hasil penelitian disimpulkan campuran limbah masker pada paving block berpengaruh signifikan terhadap berat dan kuat tekan. Variasi A dan B termasuk dalam mutu D berdasarkan SNI 03-0691-1996 yang digunakan untuk halaman rumah dan taman.

Abstract

This study focuses on optimizing biofiltration techniques to mitigate heavy metal contamination in urban wastewater. The increasing presence of heavy metals in wastewater, particularly in urban environments, poses a significant threat to both human health and ecosystem stability. Biofiltration, a natural remediation process utilizing living organisms, has gained attention as an effective method for removing heavy metals from contaminated water. The research combines experimental analysis with a comprehensive literature review to evaluate and enhance the performance of various biofiltration systems. By examining the influence of different variables, such as plant species, soil composition, flow rate, and pollutant concentration, on the efficiency of heavy metal removal, this study provides a broad perspective on the potential applications of biofiltration. Experimental analysis of biofilter setups demonstrated that specific plant-microbe interactions and substrate types significantly enhance the absorption and accumulation of toxic metals. The literature review further supports these findings by summarizing past studies and providing insights into existing biofiltration techniques, their effectiveness, and limitations. The study's findings indicate that optimized biofiltration can serve as a sustainable and cost-effective solution for urban wastewater management. By providing a detailed understanding of how biofilters can be adapted and scaled for urban applications, the research contributes to the development of environmentally friendly wastewater treatment technologies. The results underscore the importance of integrating biofiltration systems into urban water management strategies for improving water quality and reducing environmental pollution.
