Research Trends and Scientific Mapping of Natural-Based Activated Carbon Synthesis from Banana Leaf and Water Hyacinth: A Bibliometric Analysis

Abstract

This study aims to analyze scientific trends in the synthesis of activated carbon based on natural materials, especially banana leaf and water hyacinth, using a bibliometric approach based on data from the Scopus database for the period 2015-2024. Through the use of VOSviewer software, the relationship between keywords, authors, affiliations, and countries most active in this research was visualized. The results of the analysis show an increasing interest in this topic, with fluctuations in the number of publications each year. Indonesia has the most contributors, while the University of Indonesia is listed as the most productive institution. The keyword "activated carbon" dominates due to its wide application and effectiveness in adsorption. The most cited articles generally discuss carbon activation techniques and the potential of agricultural waste as a raw material. The bibliometric visualization groups the topics into several interrelated clusters, covering environmental, energy, and waste treatment issues. This research provides a comprehensive picture of the direction of development, collaboration, and research focus in the development of environmentally friendly activated carbon.
