Abstract

Children's awareness of disposing of waste in designated bins is a crucial factor in environmental health education, fostering a clean and healthy environment. A lack of understanding among children regarding waste management can be addressed through educational approaches that provide knowledge about organic and inorganic waste types. These efforts should begin early, during the formative "golden age" of behavioral development, as habits formed at this stage are easier to establish and yield more visible results in later life. Developing waste management behaviors at an early age can start with cultivating the habit of sorting and disposing of waste properly, which is expected to become a lifelong practice.The target group for this community service activity consisted of first, second, and third-grade students of SDITQ Ma’had Bakkah, Martapura. The objective of this community service initiative was to educate students who still disposed of waste carelessly, raise awareness about the importance of separating organic and inorganic waste, and implement waste sorting practices within the Ma’had Bakkah environment. The outcomes of this initiative included students gaining an understanding of the importance of maintaining cleanliness both at school and beyond, as well as learning to manage and sort organic and inorganic waste. Furthermore, the activity successfully fostered behavioral changes among the community, encouraging greater awareness and commitment to waste management and sorting within the school environment. Keywords: awareness; organic waste; inorganic waste; students (santri); Ma’had Bakkah

Abstract

Palm oil mill effluent (POME) contains recalcitrant, dye-like chromophoric compounds that are difficult to remove using conventional treatment, leading to persistent colour pollution and limiting safe discharge or reuse. Although polyamide thin-film composite (PA-TFC) membranes offer strong selectivity, their performance in high-strength wastewater is often constrained by the permeability-selectivity trade-off and susceptibility to fouling. To address this gap, this study investigates a bio-based modification strategy by integrating lignosulfonate-derived lignin particles into the polyamide selective layer to enhance pervaporation-based decolorization. Lignin-modified PA-TFC membranes were fabricated via interfacial polymerization with molar ratio MPD: TMC for 0.00925:0.0188 and 0.25% of lignosulfonate. It was then evaluated for pervaporation flux, colour rejection, and chemical stability during POME treatment. Chemical and structural characterization by FTIR indicated changes in surface functional groups consistent with enhanced intermolecular interactions between lignin and the polyamide matrix. The lignin-integrated membrane achieved an improved separation performance, reaching a flux of 17 ± 0.8 kg.m-2.h-1 with up to 85% colour rejection, outperforming the pristine polyamide membrane. The performance enhancement is attributed to improved hydrophilicity and a more favourable selective-layer microstructure enabled by the homogeneous distribution of lignin particles and hydrogen-bonding interactions within the polyamide network. Overall, incorporating lignin as a renewable additive provides a promising route to develop higher-performance PA-TFC membranes for pervaporation treatment of POME, supporting more sustainable industrial wastewater management and reducing colour-related environmental impacts.
