Abstract

This study aims to isolate nanocellulose from oil palm emptry fruit bunches (OPEFB) using acid hydrolysis method. Hydrolysis was carried out for 2 hours using 10% HCl and followed by centrifugation, ultrasonication and dialysis using a semipermeable membrane. The results obtained were tested by FT-IR, and it was found that there was a -OH functional group at a wavenumber between 3000-3500 cm-1, a C-H group in the area 2850-3000 cm-1, -CH2 bending at a wavenumber 1330-1465 cm-1 and the CO group at wave numbers 1000-1100 cm-1. This indicates that the product is in the form of cellulose. The particle size distribution of cellulose was tested with a PSA (Particle Size Analyzer) and the nanocellulose was about 7.2 nm in size.

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.
