Abstract

Nurul Islam Islamic Boarding School is an Islamic education institution in Antirogo Village, Sumbersari District, Jember Regency, East Java. Apart from being a means of education for the community, this Islamic boarding school can also create the potential for waste generation. The generation of waste in Islamic boarding school areas, especially from kitchens, can cause the earth's surface temperature to rise, resulting in climate change. Based on these problems, the service aimed to reduce the impact of waste generation by managing organic kitchen waste in urban farming products in the form of eco-enzyme and maggot cultivation. This service will occur from May 1, 2024, to November 1, 2024. This activity aims to empower Islamic boarding school residents, especially administrators and students. The method used in this service is designing Eco Enzyme fermentation tanks and maggot cultivation cages, creating a monitoring system, socializing and demonstrating tools, practising Eco Enzyme production and maggot cultivation, and program understanding tests. The results of this service activity are Urban Farming products in the form of Eco Enzyme and maggot solutions, which have been equipped with Eco Enzyme fermentation tanks and maggot cultivation cages. Another result is increasing knowledge among Islamic boarding school residents about managing organic waste in urban farming products to overcome climate change.

Abstract

Abstract Increasing industrial and human populations potentially lead to various types of water contamination and increasing water demand. Membrane technology is a popular technology that is highly efficient in separation processes and is cost-effective for water purification. One membrane technology that is widely applied in industry is microfiltration membranes. Microfiltration membranes can operate at pressures in the range of 0.02 to 0.5 MPa, thus enabling the separation of high molecular weight compounds at low pressure. Polyvinylidene fluoride (PVDF) is a commonly used microfiltration membrane material known for its excellent thermal stability, chemical resistance, and ease of membrane formation. However, PVDF has a hydrophobic structure that has low water flux. The hydrophilicity of the PVDF membrane surface modification is an effective strategy to enhance water flux. This experiment aims to increase the hydrophilicity of the membrane using polyvinyl alcohol (PVA). In this study, surface modification of the PVDF membrane is performed using polyvinyl alcohol (PVA), a hydrophilic substance that enhances the membrane's ability to attract water. The addition of 0.1% PVA yielded the average flux value, achieving 65.7 Lm⁻²·h⁻¹. PVA increases the hydrophilic properties of the PVDF membrane and could be a modification agent for water treatment or purification. Keywords: Flux, Membran Surface Modification, PVDF, PVA Abstrak Populasi manusia dan industri yang meningkat dapat mengakibatkan berbagai jenis pencemaran air dan meningkatkan kebutuhan air. Teknologi membran menjadi teknologi populer dengan tingkat pemisahan efisiensi tinggi serta harga yang relative murah untuk pemurnian air. Salah satu teknologi membran yang diterapkan secara luas di industri adalah membran mikrofiltrasi. Membran mikrofiltrasi dapat beroperasi pada tekanan dengan rentang 0,02 sampai 0,5 MPa, sehingga memungkinkan pemisahan senyawa dengan berat molekul besar bertekanan rendah. Material membran mikrofiltrasi polyvinylidene fluoride (PVDF) merupakan material dengan stabilitas termal, ketahanan terhadap bahan kimia yang baik, serta mudahnya kemampuan pembentukan membran. Namun PVDF merupakan polimer yang memiliki struktur hidrofobik yang membuat membran rentan terhadap fluks rendah. Inovasi peningkatan hidrofilik permukaan membran pada material PVDF merupakan salah satu cara efektif meningkatkan fluks pada membran. Penelitian ini bertujuan untuk meningkatkan hidrofilisitas permukaan membrane PVDF yang berpengaruh terhadap nilai fluks. Modifikasi permukaan membran pada penelitian ini menggunakan Polyvinyl Alcohol (PVA) karena PVA bersifat hidrofilik yang dapat meningkatkan kemampuan membran menarik air. Penambahan 0,1% kadar PVA nilai fluks mencapai 65,7 Lm-2h-1. PVA meningkatkan sifat hidrofilik membrane PVDF dapat menjadi salah satu agen modifikasi untu pengolahan atau pemurnian air.
