Abstract

Rendahnya kesadaran masyarakat terhadap bahan tambahan pangan dan zat kimia dalam jajanan kemasan dapat menimbulkan risiko kesehatan, khususnya di kalangan anak-anak dan orang tua di wilayah pedesaan. Program pengabdian kepada masyarakat ini bertujuan untuk meningkatkan literasi kimia pangan melalui kegiatan sosialisasi edukatif yang interaktif. Kegiatan ini dilaksanakan di Desa Bagan Serdang, Kecamatan Pantai Labu, Kabupaten Deli Serdang, Provinsi Sumatera Utara. Dengan menggunakan pendekatan riset tindakan, dilakukan tes awal dan tes akhir untuk mengevaluasi efektivitas intervensi. Hasil evaluasi menunjukkan adanya peningkatan signifikan dalam tingkat pengetahuan peserta, di mana hampir seluruh peserta memperoleh skor tertinggi pada tes akhir. Tingkat pemahaman tinggi dapat dilihat pada tes akhir yang mencapai 100% yaitu terdapat pada soal nomor 1, 2, 4, 5, 7, dan 9, sedangkan yang tidak mencapai 100%, hanya terdapat pada soal nomor 3 (86,70%), nomor 6 (73,33%), nomor 8 (80%), dan nomor 10 (93,30%). Sosialisasi interaktif telah berhasil meningkatkan pemahaman mitra tentang bahan tambahan pangan dalam jajanan kemasan.

Abstract

Durian (Durio zibethinus) peel, an abundant agricultural waste in Southeast Asia, represents a sustainable lignocellulosic precursor for producing activated carbon (AC) with high surface area and porous structure. However, pristine durian peel-derived AC exhibits limited intrinsic antibacterial activity, primarily relying on physical adsorption. Silver nanoparticles (AgNPs) are well-known broad-spectrum antibacterial agents that disrupt bacterial membranes, generate reactive oxygen species (ROS), and interfere with cellular processes. Immobilization of AgNPs onto AC is expected to create a synergistic composite that combines adsorptive capacity with potent bactericidal effects. This literature review systematically examines the synthesis and characterization of activated carbon from durian peel, green synthesis routes of AgNPs using durian peel extract or pectin as reducing and stabilizing agents, and the potential of AgNP-modified durian peel AC for enhanced antibacterial performance. Key findings indicate that chemical activation (KOH or acid-based) yields AC with surface areas ranging from 257 to 666 m²/g. Pectin extracted from durian peel enables eco-friendly synthesis of stable, spherical AgNPs (core size ≈13.5 nm, zeta potential ≈ –50 mV) with minimum inhibitory concentrations (MIC) of 61.8 ppm against both Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus. Comparative analysis reveals that while pristine durian peel AC shows only moderate bacterial capture, AgNP integration significantly improves bactericidal efficacy through combined adsorption-bactericidal mechanisms. Potential applications include water disinfection, antimicrobial filters, and biomedical materials. Challenges such as silver leaching, scalability, and long-term stability are discussed. This review highlights the emerging potential of AgNP-modified durian peel activated carbon as a low-cost, multifunctional material for addressing bacterial contamination while promoting waste valorization. Future research should focus on direct composite synthesis, comprehensive antibiofilm testing, and real-matrix performance evaluation.

Abstract

This study investigates the surface chemical characteristics of ZnO-functionalized activated carbon (AC) derived from oil palm empty fruit bunches (OPEFB) using Fourier Transform Infrared (FTIR) spectroscopy. Activated carbon was prepared through carbonization at 400 °C followed by chemical activation using KOH. ZnO functionalization was performed via the sol–gel method with a nominal ZnO loading of 10 wt% relative to AC. FTIR analysis revealed dominant absorption bands corresponding to O–H stretching (~3430 cm⁻¹), C=O stretching (~1630 cm⁻¹), and C–O vibrations (~1050–1100 cm⁻¹), indicating the presence of oxygen-containing surface functional groups. The appearance of a characteristic Zn–O vibrational band in the 450–600 cm⁻¹ region confirmed the incorporation of ZnO within the composite structure. Minor peak shifts and variations in band intensity observed after ZnO modification suggest changes in the local chemical environment and possible interactions between ZnO nanoparticles and oxygen-containing functional groups. However, FTIR analysis alone does not provide definitive confirmation of specific interfacial bonding configurations. The results indicate that KOH activation preserved reactive oxygenated functionalities that remained stable after ZnO incorporation. The coexistence of porous AC characteristics and ZnO-associated vibrational features suggests that the synthesized AC/ZnO composite possesses surface chemical properties relevant for adsorption-assisted photocatalytic applications. This work demonstrates the potential valorization of OPEFB biomass into functional carbon-based hybrid materials.
