Abstract

Greenhouse gas (GHG) emissions are the primary driver of climate change and have become a significant concern in recent decades due to their increasing atmospheric concentration. This study aims to systematically review research trends on GHG emissions over the past 20 years using bibliometric analysis. A total of 1,035 articles were analyzed through VOSviewer to map knowledge structure, research dynamics, and emerging topics. The results show that GHG emission research is divided into six main clusters: (1) gas emissions, (2) industrial and waste management, (3) air quality and human health, (4) bioenergy and energy systems, (5) food production, and (6) global climate change mitigation. Research trends indicate a shift from sectoral studies, particularly agriculture and livestock production (2005–2016), to a more integrated and systemic approach involving energy systems, air quality, and human health (2020–2024). The density visualization highlights “gas emission” as the most frequent and central keyword. Moreover, keywords such as "Municipal Solid Waste Treatment," "Energy Production," and "Domestic GHG Mitigation" have emerged as future research hotspots. This study provides a comprehensive overview of GHG emission research developments and offers valuable insights for identifying future research directions and supporting GHG mitigation strategies.

Abstract

The potential of biomass energy in Indonesia has not been optimally utilized as a sustainable renewable energy alternative, while the use of biomass without processing has the potential to cause environmental impacts. One form of biomass processing that has potential is the production of briquettes using agricultural waste, including rice husks, which have generally only been burned. This study aims to analyze rice husk production and the environmental economic feasibility of its use as biomass briquettes. The methods used include field observations, interviews, and environmental economic feasibility analysis. The results of data collection show that Sumber Agung Village, Suoh District, West Lampung Regency produces 2.5 tons of rice husks per week from 10 rice mills that have been operating for 2–35 years. The feasibility analysis shows a net present value (NPV) of IDR 739,672,991.96, an interest rate of return (IRR) of 10.73%, and a benefit–cost ratio (BCR) of 1.09, indicating that the utilization of rice husks into briquettes is feasible. The results of this study are expected to serve as a basis for consideration in determining the form of sustainable utilization of agricultural waste, particularly rice husks.
