Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk menanamkan kesadaran akan pentingnya pelestarian lingkungan hidup, dimulai dari lingkungan sekolah. Inisiatif ini berfokus pada memberikan bekal keterampilan kepada guru dan siswa untuk melakukan manajemen pemilahan sampah secara mandiri. Dengan meningkatnya volume sampah di sekolah-sekolah, diperlukan partisipasi yang lebih aktif dari guru dan siswa dalam pengelolaan sampah. Salah satu bentuk partisipasi paling sederhana adalah dengan memilah sampah organik dan anorganik. Namun, saat ini masih sedikit guru dan siswa yang mau terlibat dalam upaya tersebut. Oleh karena itu, Oleh karena itu, kegiatan ini diadakan untuk mengedukasi siswa dan guru SMA Sains Alumnika Palembang dalam teknik pemilahan sampah organik dan anorganik di tempat pembuangan sampah, dengan tujuan membentuk pola pikir yang lebih baik tentang pengelolaan sampah. Adapun manfaat yang diperoleh adalah siswa dan guru dapat memperoleh pengetahuan mengenai pemilahan sampah organik dan anorganik. Tindak lanjut dari kegiatan ini adalah perlu dilakukan pelatihan lanjutan yang lebih intensif mengenai teknik pengolahan sampah organik dan anorganik sehingga peserta dapat menerapkan ilmu yang diperoleh dalam kehidupan sehari-hari, baik di lingkungan sekolah maupun di rumah.

Abstract

This study investigates the effectiveness of ZnAl-LDH modified with polyoxometalate (POM) as an adsorbent material in the competitive adsorption of heavy metal ions Cr(VI) and Fe(II). The material was synthesized using the co-precipitation method, resulting in ZnAl-LDH@POM with enhanced interlayer spacing, a specific surface area 14 times more significant, and increased surface-active sites. Characterization using XRD, FT-IR, and BET confirmed the successful structural modification and improved adsorption properties. Kinetic studies revealed that adsorption followed a pseudo-second order kinetic model, achieving maximum efficiency within 50 minutes. Isothermal analysis demonstrated maximum adsorption capacities (???????????????? ) of 92.95 mg/g for Fe(II) and 44.44 mg/g for Cr(VI). These findings highlight the potential of ZnAl-LDH@POM as an effective adsorbent for treating heavy metal-contaminated wastewater.

Abstract

Layered Double Hydroxides (LDHs) are a class of anionic clays known for their tunable structure, high surface area, and versatile ion exchange capabilities, making them highly attractive for environmental remediation. This critical review explores the uniqueness of LDH materials by examining recent advancements in their synthesis methods, structural and physicochemical properties, and the development of LDH-based composites. Various synthesis approaches including co-precipitation, hydrothermal, and mechanochemical methods are evaluated in relation to their influence on LDH morphology, stability, and functionality. The review also highlights the integration of LDHs with other materials such as metal oxides, carbon-based supports, and metal organic frameworks (MOFs), which enhance their photocatalytic and adsorptive performances. Special attention is given to the mechanisms underlying pollutant removal, including ion exchange, surface complexation, and photocatalytic degradation. Comparative analysis of different modifications reveals trends in application performance and identifies current challenges that must be addressed to optimize LDHs for large-scale and multi-functional environmental applications. This review provides critical insight into the future potential of LDH materials as sustainable and efficient solutions for water and wastewater treatment.
