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 increase in laundry service activities in Indonesia has an impact on the high water pollution due to the disposal of laundry waste containing chemicals such as COD, TDS, and Phosphate. Laundry waste, which is discharged directly into the environment without treatment, can lead to eutrophication, deterioration of water quality, and the death of aquatic biota. Phytoremediation with a constructed wetland system using genjer plants (Limnocharis flava) was chosen as an environmentally friendly, and low-cost treatment alternative. This study aims to analyze the effectiveness of reducing COD, TDS, and Phosphate levels of laundry waste with genjer plants in the constructed wetland system, as well as to analyze the relationship between the 0, 4th, 8th and 12th day stay time on the reduction of parameters before and after treatment. Preliminary experiments used a control reactor (without plants) and a treatment reactor (10 plants). The results of this study showed the ability to set aside the largest removal in the treatment reactor at COD levels of 88,147%, TDS of 12,776% and phosphate of 14,911% on day 12.. This shows that the constructed wetland method is relatively effective to be applied as laundry waste treatment.
