Abstract

It is projected that global waste production will reach 3.4 billion tons by the year 2050, with 33% of this waste not managed in an environmentally sustainable manner. Since the beginning of the 21st century, there has been a significant increase in household and industrial waste, which poses major environmental, public health, and policy challenges. This study employed a systematic literature review (SLR) approach and bibliometric analysis to map global solid waste research trends. The data were collected in three stages: article identification, eligibility screening, and metadata extraction. These data were then analyzed using VOSviewer 1.6.20. A comparative analysis revealed a paradigm shift from a linear approach towards a circular economy model between 2004 and 2024. The period 2014-2024 signifies the consolidation of the concept of sustainability, marked by a 72% increase in network complexity. The research focus underwent a shift from municipal solid waste management to circular economy systems, which are now linked to 38% more derived concepts. New subjects, such as plastic pollution and post-consumption plastic waste, have emerged as predominant themes in 28% of recent publications. The density visualization demonstrates the most significant concentrations in the domains of circular economy and municipal waste management. There has been a marked increase in research activity in recent years, particularly with respect to plastic pollution and waste valorization.

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.

Abstract

This study aims to determine the water quality status of the Musi River in Palembang City in the dry season (July) and the rainy season (October) using the STORET and Pollution Index (PI) methods, as a scientific basis for evaluating seasonal pollution dynamics and supporting sustainable river management. Water samples were collected from four representative sampling sites along the Musi River in Palembang City, representing the upstream reach, industrial zone, urban reach, and downstream section. Primary data were obtained from field measurements of physical and chemical parameters, while secondary data were obtained from water quality standards and related literature. Water quality determination using the STORET method was based on deviations from regulatory standards, while the PI method estimated the average pollution load. The results show that several parameters exceed the allowed limits, with the STORET method generally classifying the river as moderately polluted, whereas the PI method classifies it as lightly polluted. This study evaluated the water quality of the Musi River in Palembang City using the STORET method and the Pollution Index at four sampling locations in the dry and rainy seasons. The STORET analysis showed that four points fell into the moderately polluted category (score: -12 to -20), while the PI method showed lightly polluted throughout the area (Pij score: 2.29 to 3.07). The results underscore the urgent need for integrated pollution management to ensure regulatory compliance and protect ecosystems.
