Abstract

The waste problem is one of the environmental problems that has not been resolved properly in Indonesia. One of the efforts to reduce is by sorting waste based on its type so that it is easier to determine the next processing method and applying the 3Rs (reuse, reduce, and recycle) to prevent and reduce waste piles. The application of the 3R concept has proven to be an effective solution to minimize the negative impact of waste on the environment. The method used in this activity uses an interactive method. This activity involved measuring students' knowledge through post-test and post-test, the results of which were tested using the Wilcoxon test with a p-value of 0.000. The analysis showed a significant difference in the students' knowledge level, with more than 50 percent of the participants having increased knowledge, indicating the effectiveness of this educational program. Through this activity, it is hoped that a culture of environmental care will be created among students that can have a positive impact on the school environment and the surrounding community.

Abstract

Ferrite nanoadsorbents have attracted increasing attention for heavy metal remediation because of their magnetic separability, high adsorption capacity, and potential reusability. This review provides a comprehensive synthesis of research developments by integrating bibliometric mapping with an analysis of adsorption mechanisms and emerging research challenges. A bibliometric literature review was conducted using Scopus-indexed publications published between 2011 and 2025. After a systematic screening process, relevant research articles were analyzed to identify publication trends, collaboration networks, leading journals, research hotspots, and thematic evolution. The findings reveal sustained growth in research activity, with contributions concentrated in high-impact journals and strong international collaboration led primarily by Asian countries. Keyword mapping indicates that research has evolved from fundamental heavy metal removal studies toward mechanistic investigations of adsorption processes and, more recently, to the development of advanced ferrite-based nanocomposites emphasizing recyclability, stability, and environmentally sustainable water treatment. Mechanistic analysis further shows that adsorption performance is governed by the synergistic effects of surface functional groups, pore structure, adsorption kinetics, and magnetic recovery. Despite substantial progress, challenges remain regarding nanoparticle agglomeration, regeneration efficiency, long-term environmental safety, and large-scale commercialization. This review provides an integrated understanding of the evolution of ferrite nanoadsorbent research while identifying critical knowledge gaps and future research priorities to support the development of efficient, sustainable, and practically applicable water remediation technologies.
