Abstract

Energy is essential for human life, yet dependence on fossil fuels and other non-renewable resources contributes to global energy crises and environmental degradation. Biogas is an environmentally friendly alternative that has the potential to partially replace fossil fuels. Palm Oil Mill Effluent (POME), which contains high concentrations of biodegradable organic matter, is a promising substrate for biogas production through anaerobic fermentation. This study aims to evaluate the potential of Palm Oil Mill Effluent (POME) as a substrate for biogas production using a Continuous Stirred Tank Reactor (CSTR) under mesophilic conditions (35–37oC). The experiment was conducted for 30 days with at a laboratory scale (10 L reactor volume). Feedstock characterization (COD, TSS, TS, VS, and pH) confirmed that POME has high organic content and slightly acidic conditions, supporting its suitability for anaerobic digestion. The results show that anaerobic fermentation of POME produced biogas with an average methane (CH4) concentration of 66–71%, indicating stable digestion performance and relatively high efficiency. These methane levels indicate stable digestion performance and relatively high process efficiency. Overall, the findings confirm that POME is a promising feedstock for biogas production and can contribute to renewable, environmentally friendly energy supply.

Abstract

Anthropogenic activities have degraded peatlands in various regions worldwide. To protect and restore peatlands and their ecosystems, sustainable peatland restoration efforts have been undertaken. These efforts have attracted the attention of researchers to assess the success rate, benefits, and protection of restored ecosystems. This study highlights trends, issues, and recent developments through a bibliometric analysis of articles on peatland restoration from an environmental security perspective, published in the Scopus database. The researcher identified 94 journal articles published between 1994 and 2022 and analyzed them using VOSviewer and NVivo 12 Plus software. The results show that research on peatland restoration is playing an important role from an environmental security perspective with increasing recent progress, and has high relevance for rewetting, revegetation, and cost benefits. In contrast, the main issues in peatland restoration are water, ecosystem, and carbon. Experts measure restoration progress through water levels and related issues. Then the peatland ecosystem absorbs about 30% of the world’s carbon and vice versa; when degraded, they release carbon. Recommendations for future research focus on harmonizing peatland restoration efforts with an environmental security perspective and educating local communities about the benefits that can increase the success of restoration and preservation of peatland ecosystems, as well as efforts to increase protection through advocacy for these marginal ecosystems.

Abstract

The combustion of coal in power plants (PLTU) generates fly ash containing silica dioxide (SiO?) and alumina (Al?O?), which exhibit promising properties as adsorptive materials. Fly ash, typically regarded as an industrial by-product, has been widely explored for its application as an adsorbent in wastewater purification. One of the most challenging wastewaters is acid mine drainage, characterized by strong acidity (pH < 5), residual contaminants, and elevated concentrations of heavy metal ions such as manganese (Mn) and iron (Fe). When released untreated, this effluent poses significant risks to both surface and groundwater quality in mining areas. This study focuses on the characterization and utilization of fly ash as an adsorbent to neutralize acidity and reduce Mn and Fe concentrations in acid mine drainage. The material was characterized using SEM-EDX and XRD techniques, followed by adsorption experiments. To enhance its properties, fly ash underwent physical activation through heating at 100 °C for 60 minutes. The activation process modified its structure, expanding pore volume and increasing surface area, thereby improving adsorption performance. The experimental results revealed significant differences in the properties of fly ash before and after activation. Activated fly ash effectively raised the pH of acid mine drainage to near-neutral conditions while achieving removal efficiencies of 96.61% for Mn and 83.33% for Fe using 50 g of adsorbent. These findings highlight the potential of fly ash as a low-cost and effective material for acid mine drainage treatment, both for acidity control and heavy metal removal.

Abstract

Low-carbon aquaculture is increasingly recognized as a vital strategy to mitigate climate change, improve resource efficiency, and ensure sustainable food production. This systematic review, following the PRISMA 2020 protocol, analyzed 58 peer-reviewed studies selected from 312 published between 2020-2024, providing a transparent and replicable synthesis of the current evidence. Research is predominantly focused in Asia and Europe, regions where rapid aquaculture growth coincides with emerging climate policies. Key strategies for reducing environmental impacts include Integrated Multi-Trophic Aquaculture (IMTA), cultivation of low-trophic species such as seaweeds and filter feeders, and the restoration of coastal ecosystems, all of which enhance carbon sequestration, nutrient cycling, and ecosystem resilience. The review identifies the most commonly reported sustainability indicators as global warming potential (GWP), energy consumption, land use, nutrient loading, and eutrophication. Despite ongoing technological innovations, global aquaculture remains largely unsustainable with persistently low environmental performance. Barriers to improvement include incomplete carbon accounting, fragmented regulatory frameworks, and limited consumer awareness. Additionally, significant knowledge gaps in greenhouse gas emissions and carbon sequestration constrain robust life cycle assessments. Transitioning to low-carbon aquaculture requires not only technological innovation but also with stronger governance, ecosystem-based management, and integrated policy frameworks to enhance sustainability and climate resilience. This review underscores the urgency of coordinated action across research, industry, and policy sectors to optimize low-carbon strategies, address existing knowledge gaps, and support the development of sustainable aquaculture systems that are both environmentally responsible and economically viable.

Abstract

Higher education institutions must implement appropriate evaluation and strategy determination to support their role in establishing a Sustainable Campus. This study aims to (1) evaluate the implementation of the sustainable campus program at Universitas Sebelas Maret (UNS), (2) analyze the dominance of internal (IFAS) and external (EFAS) factors at UNS, and (3) formulate strategies that UNS should implement to strengthen its sustainable campus initiatives-the implementation evaluation utilized data from the UNS GreenMetric report. The factor dominance analysis employed IFAS and EFAS, while the strategy formulation used SWOT-TOWS analysis. The findings indicate that UNS has stagnant scores in the Water (WR) and Transportation (TR) indicators. Furthermore, UNS’s strengths lie in its open space availability and sustainable academic programs, though this advantage is hindered by limited budget allocation for toxic waste management. Based on the analysis, the recommended course of action for UNS is the Strengths-Opportunities (SO) strategy. The implementation of this SO strategy is necessary for UNS to advance its role as a sustainable campus successfully. This study implies that the integration of sustainability performance evaluation using UI GreenMetric data with IFAS, EFAS, and SWOT-TOWS analysis provides a structured basis for identifying dominant strategic conditions and formulating strength-oriented strategies to improve sustainable campus implementation at Universitas Sebelas Maret. The study implies that Universitas Sebelas Maret should utilize sustainability assessment results as strategic inputs rather than merely as reporting tools, enabling more targeted interventions in critical areas such as water and transportation management. These findings may further contribute to the development of management strategies derived from SWOT and TOWS analyses in other universities across Indonesia.

Abstract

Industrial rubber wastewater contains high levels of organic substances (proteins, carotenoids, organic salts, and lipids in residual latex) that can be observed in high concentrations of BOD5 (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand). Pineapple waste is an organic waste that can be utilized as a bio-adsorbent to remove pollutants from wastewater. This study aims to investigate the effectiveness of pineapple crown waste activated with KOH in removing BOD5 and COD in rubber industry wastewater. The effectiveness of the adsorbent was tested in batches at varying adsorbent dosages of 0.5 g, 1.0 g, and 1.5 g at stirring speeds of 50 rpm, 100 rpm, and 150 rpm. The adsorption isotherm model was analyzed using the Langmuir and the Freundlich models. The results showed that the optimum BOD5 removal rate in rubber industry wastewater using pineapple crown adsorbent was achieved at an adsorbent dosage of 0.5 g with a stirring speed of 100 rpm, resulting in an adsorption capacity of 62.78 mg/g and a removal efficiency of 94.35%. The optimum COD removal was achieved at an adsorbent dosage of 0.5 g, with a stirring speed of 100 rpm, resulting in an adsorption capacity of 199.816 mg/g and a removal efficiency of 95.15%. The adsorption isotherm model most suitable for both BOD5 and COD is the Freundlich model. Increasing the adsorbent dosage does not significantly enhance removal efficiency.

Abstract

The dispersion of pollutants originating from traffic activities has become a major environmental issue in many developing countries. Emissions such as SO2 and CO present significant challenges for air quality management due to their serious health impacts. Air Quality Monitoring Systems (AQMS) are commonly used to measure pollutant concentrations; however, limited availability and spatial coverage necessitate alternative approaches such as dispersion modeling using AERMOD. This study aims to evaluate the performance of AERMOD as an alternative method for estimating SO2 and CO concentrations, particularly those associated with traffic-related emissions. The simulation results indicate a strong alignment between dominant wind direction and pollutant dispersion patterns over the seven-day modeling period. Concentration accuracy assessed through regression analysis and Root Mean Square Error (RMSE) revealed positive correlations between AERMOD simulations and observational data for both SO2 and CO, with RMSE values of 21.86 µg/m3 for SO2 and 485.25 µg/m3 for CO. Overall, statistical evaluations demonstrate a high level of agreement for SO2 and a moderate level of agreement for CO. These findings underscore the significant potential of AERMOD as an alternative monitoring tool for estimating pollutant dispersion in areas lacking AQMS infrastructure, thereby supporting more effective air quality management and pollution control strategies. However, the model’s performance remains influenced by several limitations, including dependency on the quality of meteorological and emission input data, the assumption of steady-state atmospheric conditions, and greater prediction uncertainty for CO compared to SO2. These factors should be carefully considered when applying AERMOD in regions without ground-based monitoring stations.

Abstract

This study examines how Indonesian mining companies incorporate climate action within their corporate social responsibility (CSR) strategies, with a particular focus on their contributions to Sustainable Development Goal (SDG) 13. Using qualitative content analysis of ten publicly available CSR and sustainability reports, the study identifies recurring themes in corporate disclosures, including operational activities, environmental performance data, target-setting, and collaborative initiatives. The findings reveal both progress and gaps in aligning mining practices with national and international climate objectives. Four thematic areas emerge, including (1) operational decarbonization efforts that increasingly combine low-carbon technologies with nature-based solutions (NbS), although their effectiveness is rarely assessed through standardized indicators; (2) responsibility framing and measurable targets that show greater alignment with frameworks such as the Paris Agreement and Indonesia’s Nationally Determined Contributions, yet governance and assurance mechanisms remain underdeveloped, raising concerns of potential greenwashing; (3) while disclosure of environmental data has improved, comparability across firms is constrained by inconsistent adoption of metrics and limited integration of Life Cycle Assessment (LCA); and (4) climate-related risks are widely acknowledged, with firms outlining resilience strategies and engaging in multi-stakeholder partnerships to enhance adaptive capacity. Overall, Indonesian mining companies demonstrate a growing recognition of their role in climate action. However, advancing their contribution to SDG 13 requires systematic evaluation of NbS, stronger ESG governance and accountability, broader institutionalization of LCA, and deeper stakeholder engagement. These improvements are essential to ensure CSR initiatives deliver substantive, measurable, and socially inclusive climate outcomes.

Abstract

Industrial symbiosis presents a transformative pathway for the sustainable management of palm oil byproducts. This study investigates a novel integrated valorization approach using boiler ash as a multifunctional ameliorant in the anaerobic fermentation of palm oil mill effluent (POME). By leveraging the synergistic physicochemical properties of acidic POME and alkaline boiler ash, we developed a self-buffering system to produce high-value liquid organic fertilizer. Varying boiler ash concentrations (0, 45, 50, and 55 g/L) were evaluated to determine the optimal nutrient recovery and stabilization parameters. Results demonstrate that a dosage of 55 g/L is statistically superior, effectively neutralizing the system to a stable pH of 7.5 without synthetic additives. This treatment yielded a nutrient-dense product containing 3.93% total NPK and 12.42% organic carbon, surpassing the Indonesian Ministry of Agriculture Regulation No. 261/2019 standards. Safety analysis revealed a Pb concentration of 12.28 ppm, which is significantly below the maximum allowable threshold, confirming the product’s environmental compatibility. This research provides a scientifically grounded method for converting industrial waste into a fortified agricultural input, advancing circular economy principles and supporting national sustainability frameworks like the Indonesia Sustainable Palm Oil (ISPO) certification.
