Abstract

Processing municipal solid waste into refuse-derived fuel (RDF) is an alternative solution to the waste problem. This study determined the potential environmental impact of Sleman RDF as an energy diversification agent in the cement industry using life cycle assessment (LCA). The boundary system of this study is gate-to-grave, with a functional unit of co-firing energy requirements for the production of 1 metric ton of clinker. Two clinker co-firing scenarios were developed, involving a combination of coal and alternative fuels. The results showed that the production of 1 metric ton of clinker requires a large amount of resources and contributes significantly to climate change, ecosystem toxicity, and human toxicity. Co-firing clinker in the alternative scenario successfully reduced the potential environmental impact by 14% with a thermal substitution rate of 20%. The findings of this study indicate that RDF is effective in reducing dependence on fossil fuels and lowering emissions and the potential environmental impact.

Abstract

This review is the first attempt to integrate natural and anthropogenic drivers of coastal subsidence, the evolution of monitoring techniques, and geo-environmental impacts, with a focus on coupled human-environment systems. This review compares traditional geodetic techniques (levelling, GNSS) with other satellite and geophysical methods (InSAR, LiDAR, microgravity, and seismic survey) and assesses subsidence monitoring under different geo-environmental conditions. Empirical evidence from the northern coastline of Java, in particular Semarang, shows that subsidence has occurred at an annual rate of 2–10 + cm, which is directly linked to groundwater exploitation, alteration of land use, and coastal construction, which exacerbates tidal flooding, coastal recession, saltwater encroachment, ecosystem destruction, infrastructure deterioration, and social impacts. The findings suggest that subsidence is a unique geophysical phenomenon and not a result of anthropogenic interactions with natural systems involving water, land use, coasts, and public administration frameworks. This type of integration is essential for improved risk assessment, resilience, and sustainable development.

Abstract

Batik wastewater contains high levels of total suspended solids (TSS) and turbidity, making it difficult to decompose naturally. To prevent environmental pollution, this study investigated a treatment method that combined coagulation in a mixing tank and flocculation using a hydrocyclone. Polyaluminum chloride (PAC) was used as the coagulant. The coagulation process was tested at stirring speeds of 100–140 rpm and coagulant doses of 150–300 mg/L. The results showed that a coagulant dose of 300 mg/L and a stirring speed of 140 rpm achieved the highest removal efficiencies: 95.45% for TSS and 95.24% for turbidity. A two-way analysis of variance (ANOVA) confirmed that the coagulant dose significantly affected removal efficiency (p=0.049), whereas the stirring speed did not have a significant effect (p=0.77). Furthermore, particle size analysis (PSA) and zeta potential tests indicated that the PAC coagulant successfully destabilized the suspension in the wastewater, leading to the formation of large aggregates and accelerating the separation process. Overall, these results indicate that combining a coagulation mixing tank with a hydrocyclone flocculation unit offers an efficient and rapid solution for treating batik wastewater.

Abstract

River water pollution from domestic and industrial waste remains a major challenge in Indonesia’s environmental governance. The Clean River Program (PROKASIH) was established as a national initiative to control water pollution through collaboration among government agencies, industries, and local communities. However, local implementation often faces constraints, particularly limited community participation and insufficient integration of environmentally friendly infrastructure. This study evaluates the implementation of the Clean River Program in Sukoharjo Regency, examines community participation, identifies influencing factors, and develops an improvement strategy based on social cohesion and sustainable technology. A mixed-methods approach was applied, combining river water quality analysis, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, total suspended solids, nitrate, and phosphate, with a survey of 100 respondents and in-depth interviews. Reliability testing produced a Cronbach’s alpha value of 0.86, while Spearman ’scorrelation analysis showed a significant relationship between education level and participation. The results indicate a program success rate of 58.7%, with community participation classified as moderate. This study proposes the Green–Community River Management (G-CRM) framework, integrating participatory governance and eco-friendly infrastructure to strengthen PROKASIH implementation in line with the 2023–2030 KLHK Clean River Program Roadmap and support Sustainable Development Goal 6.3.

Abstract

Wastewater from metal plating businesses contains hazardous heavy metals, including chromium (Cr), which must be properly treated to avoid environmental contamination. Adsorption utilizing natural materials, such as sugarcane bagasse, is a promising option. This study compared the effectiveness of H2SO4-activated sugarcane bagasse with sugarcane bagasse-based activated carbon in removing total chromium (Cr-T) from metal plating wastewater and analyzed the effects of adsorbent mass and contact time. Atomic absorption spectrophotometry (AAS) was used to measure the final chromium concentrations after batch adsorption was conducted with different masses and contact periods. The findings revealed that the adsorption effectiveness increased as the adsorbent mass and contact duration increased, reaching an ideal point. While activated carbon achieved its peak at 12 g and 120 min (95% and 47.6% efficacy, respectively), activated bagasse performed best at 15 g and 150 min (51.9% and 43% effectiveness, respectively). Activated carbon performed better because of its increased surface area and pore structure resulting from carbonization. These results demonstrate that sugarcane bagasse is a potential, affordable, and sustainable natural adsorbent for lowering total chromium in industrial effluents, particularly when transformed into activated carbon.

Abstract

Groundwater contamination with iron (Fe) and manganese (Mn) remains a significant challenge in rural areas with limited access to modern water treatment technologies. In the Margorejo Village, Tempel District, Sleman, groundwater from domestic wells exhibited elevated Fe and Mn concentrations related to local geochemical conditions. This study investigated the efficacy and acceptance of a hybrid phytocoagulation system combining extracts from Eichhornia crassipes and Moringa oleifera seeds to enhance metal removal through a combination of biosorption, biooxidation, and protein-induced flocculation. Variations in plant biomass (0–30 leaves), Moringa dose (0–100 mg/L), and contact time (0–16 days) were investigated in a factorial randomized block trial. The optimal configuration (30 leaves, 100 mg/L, 16 days) reduced the iron concentration to 0.082 mg/L (97.77%) and the manganese concentration to almost zero (98.71%). Pearson correlation analysis revealed a strong positive correlation between iron and manganese concentrations (r=0.821), indicating similar geochemical behavior. A public perception analysis with 30 respondents showed high acceptance (75.72%), particularly in households directly affected by contamination. These results demonstrate that hybrid phytocoagulation is a cost-effective, environmentally sustainable, and socially acceptable method for decentralized groundwater treatment and underscore the importance of public participation for long-term implementation

Abstract

Wastewater from crude palm oil production is among the most concentrated agro-industrial effluents, marked by very high organic loads, suspended solids, and variable composition. Conventional treatments often struggle to consistently remove recalcitrant pollutants such as phenolics, color compounds, and emulsified oil. As a result, adsorption has gained global attention as a versatile and efficient alternative. This review summarizes recent advances in adsorption technologies for crude palm oil wastewater treatment. It highlights progress in adsorbent development, including biochar, mineral composites, layered double hydroxides, magnetic hybrids, and other engineered materials. Key removal mechanisms for organics, nutrients, and colloids are examined alongside insights from kinetic, isotherm, and thermodynamic studies. The integration of adsorption with biological, membrane, and oxidation processes is also discussed, demonstrating improved removal efficiency and effluent stability. Major challenges remain, particularly in mechanical stability, regeneration, competitive adsorption, and large-scale validation. Future research should prioritize process intensification, sustainable regeneration methods, circular-economy-based adsorbent production, and life-cycle assessment. Overall, adsorption represents a promising pathway toward more sustainable and reliable crude palm oil wastewater management

Abstract

The management of industrial wastewater presents a considerable challenge to governments globally, mainly because of the difficulties faced in ensuring that regulatory frameworks are properly instituted. This study evaluated the success of the technical approval for using wastewater" regulatory framework and its geographic spread across East Java. This was evaluated using data from 35 business participants from 16 different districts/cities via a combination of quantitative (survey) and qualitative (spatial analysis) methods. The overall effectiveness of the regulatory framework was rated high (84.69%), with the dimension "Regulatory Appropriateness" rated the highest (85.57%), while the dimension "Environmental Appropriateness" ranked the lowest (84.14%). From the geographic analysis, it was evident that cities and industrial centers dominated the level of support, with many non-industrial areas displaying very little engagement. Collectively, these results demonstrate the need for policies to be designed with a geographic perspective and for sufficient institutional support to be targeted towards non-urban areas. This will allow stakeholders to provide the required technical support, increase the utilization of technology to enhance service delivery, and engage the local workforce to the greatest degree possible to enable sustainable and equitable environmental governance.

Abstract

Palm kernel shell (PKS), a major by-product of the palm oil industry, has emerged as a promising sustainable feedstock for solid biofuel briquettes. This study presents a systematic review of PKS briquettes, emphasizing their thermal properties, briquetting technologies, pretreatment methods, environmental and economic impacts, and future prospects. A PRISMA-based methodology was applied to ensure transparent identification, screening, and synthesis of relevant peer-reviewed studies on PKS briquette production and performance. The review indicates that PKS briquettes generally possess high calorific value, substantial fixed carbon content, and competitive combustion performance compared with other biomass fuels. Advances in densification techniques and pretreatment processes have improved fuel quality, durability, and energy efficiency. Despite these strengths, several research gaps persist. Standardized data on thermal conductivity and heat transfer remain limited, and comparative assessments with conventional fuels such as coal and firewood are insufficient. Moreover, inconsistencies in experimental conditions hinder cross-study evaluation, while emissions characteristics and large-scale industrial feasibility are underreported. By consolidating current findings and identifying critical knowledge gaps, this review offers a structured foundation for future research and informed policymaking, supporting the integration of PKS briquettes into sustainable energy and circular economy strategies in palm oil–producing regions.
