Abstract
The global transition toward renewable energy has become a crucial step in addressing the ongoing energy crisis and climate change. Among various renewable options, biogas stands out as a sustainable solution that not only reduces dependence on fossil fuels but also promotes circular economy practices through the utilization of organic waste. This study aims to explore the trends and dynamics of biogas research over the past decade using a bibliometric approach, focusing on efficiency, sustainability, and the integration of IoT-based smart monitoring technology. The method employed is a quantitative and descriptive bibliometric analysis of scientific publications indexed in Scopus from 2015 to 2024. The findings reveal a consistent increase in biogas-related publications, with dominant research themes including anaerobic digestion, optimization, renewable energy, and biomethane. The co-occurrence mapping identifies five major research clusters emphasizing system optimization, substrate biotechnology, microbial ecology, energy purification, and energy sustainability. The results highlight a clear shift in research direction toward digitalization and the application of smart monitoring systems based on IoT, which enhance efficiency and operational stability. In conclusion, biogas research is evolving toward a smart renewable energy paradigm—anchored in efficiency, sustainability, and digital innovation as the foundation for future energy management.
