Abstract

Aims: The current study aimed to investigate the feasibility of biohydrogen production from tomato and cabbage waste through dark fermentation with Trichoderma spp. supplementation to enhance substrate degradation. Methodology and results: Laboratory-scale anaerobic reactors with five different Trichoderma concentrations (0.0, 2.5, 5.0, 7.5, and 10.0 g) were operated at room temperature for 112 days, during which hydrogen production, glucose consumption, pH, and temperature were continuously monitored. The highest cumulative hydrogen yield was observed in the treatment with 2.5 g of Trichoderma, achieving 44.65 mmol H₂/mol glucose, which is three times greater than the control. Correlation analysis revealed that optimal biohydrogen production was associated with extended incubation periods, elevated temperatures, and lower pH levels (below 6.0); however, increased concentrations of Trichoderma did not consistently enhance hydrogen yield. The liquid digestate from the best-performing reactor was applied as a biofertilizer for chilli seedlings. The 5% digestate treatment significantly promoted plant height and leaf growth compared to the control, suggesting the beneficial effects of bioactive compounds produced by Trichoderma. Conclusion, significance, and impact study: Reactor supplemented with 2.5 grams of Trichoderma exhibited the highest biohydrogen production, and a 5% digestate concentration enhanced the growth of chilli seedlings. This study demonstrates the dual potential of agricultural waste valorisation, producing renewable energy and supporting sustainable agriculture, highlighting the promising role of microbial-aided fermentation and biofertilizer applications in circular bioeconomy models.

Abstract

Cement-bentonite (CB) barriers are frequently employed to mitigate seepage in critical infrastructure such as dams, yet they face persistent challenges from cracking and erosion under hydraulic stresses. Aims: This study aimed to determine whether utilizing ground granulated blast furnace slag (GGBS) as an environmentally friendly partial replacement for cement could enhance the erosion resistance of CB mixtures. Methodology and Results: Laboratory tests were conducted on CB specimens with 0%, 20%, and 50% GGBS replacement, cured for 7, 14, 21, and 28 days. Mechanical integrity was assessed via tensile strength testing, whereas erosion behavior was evaluated using an erosion function apparatus (EFA), measuring erosion rate, critical velocity, and flow parameters. Results revealed that GGBS-modified CB samples experienced a tensile strength increase of up to 180% relative to the control, particularly at extended curing durations. Additionally, the critical velocity necessary to initiate erosion was as much as 94% higher in GGBS-enhanced samples, indicating improved microstructural resilience. Conclusion, significance and impact study: Partial cement replacement with GGBS strengthens CB and improves its erosion resistance, supporting GGBS as a more sustainable binder choice. Scope and limitations: Results are from lab tests on CB mixes (0-50% GGBS; 7-28-day curing; EFA velocity range). Field behaviour can vary with hydraulics, interfaces, and placement; confirm constructability and performance for project conditions.

Abstract

Music concerts have increasingly raised concerns due to their contribution to noise pollution in urban environments. Aim: this study aimed to analyze noise levels and their characteristics during outdoor music concerts in Makassar City, examine the spatial distribution of noise from the source to surrounding areas, and evaluate the effectiveness of vegetation and buildings as noise barriers. Methodology and results: Observations were conducted at 16 sampling points in the Mandala Monument area and nearby urban zones. Noise mapping was carried out using the inverse distance weighting (IDW) method, and statistical analysis was performed with paired t-tests. Results indicate that even without concerts, certain urban locations exceeded the noise standards, suggesting that urbanization alone contributes significantly to noise pollution. During concerts, noise levels surpassed the Indonesian regulatory standards, with concrete structures identified as the most effective noise barriers, reducing noise intensity by up to 17.5 dB. Conclusion, Significance, and Impact Study: The findings emphasize that outdoor music concerts substantially increase environmental noise risks in urban areas. The effectiveness of structural barriers highlights their role in urban noise management. This study underscores the urgency of implementing stricter urban planning and regulatory frameworks for concerts to mitigate environmental noise and safeguard public health.

Abstract

Aims: This paper investigates the ecological functional areas of Makassar City by utilizing land cover spatial data from 1997 and 2012 to evaluate ecological connectivity through Geographic Information Systems (GIS). Methodology and results: A spatial analysis of these ecological functional areas was conducted across different patch size categories to assess the percentage distribution of each land-use type. Additionally, the comparative distribution of the Ecological Connectivity Index (ECI) map for Makassar City was simulated. The findings indicate a decline in connectivity levels in previously natural areas surrounding Makassar, particularly in the western and eastern regions of the city. The ECIs have significantly decreased from 1997 to 2012, primarily due to the impacts of urban development in low-density, dispersed suburban areas. The results suggest that optimal quantitative criteria for ecological functional areas at the city scale of Makassar can be classified within patch size spectrum III. Implementing well-designed strategies could help mitigate the loss of ecological connectivity, thereby supporting the protection and restoration of Makassar’s environmental integrity. Conclusion, Significance, and Impact of Study: from a landscape ecological perspective, a significant trend observed in Makassar City over the past fifteen years has been the rapid fragmentation and transformation of its natural landscape. This has led to the emergence of numerous habitat patches that are progressively smaller and more disconnected. A thorough understanding of the interactions between spatial patterns and ecological processes across various scales is essential for effective landscape and environmental studies.

Abstract

Aim: Waste sorting at-source is vital for sustainable waste management and the circular economy in Indonesia. Despite regulations, community programs, and digital interventions, sorting remains limited. This study explores self-reported sorting behaviors among urban residents and examines how waste banks may enhance participation. Methodology and results: We surveyed 220 respondents from Indonesian major cities and applied Two-Step Cluster Analysis and chi-square tests to assess links between sorting behavior, socio-demographics, and waste bank participation. The main barriers were lack of space and time. The 57 respondents with access to a waste bank, only 14 were members; 43 were uninterested, often citing inconvenience. Active members were positive about the possibility of automation technologies, including automated sorting and collection, weighing machines for pricing, and digital payments. Many also suggested a mobile app to track deposits. Conclusions, Significance, and Impact: Technological innovations paired with incentives potentially reduce participation barriers. Integrating digital and automated solutions with behavioral insights may help overcome current limitations and foster a more effective circular economy in Indonesia.

Abstract

Office-based operations in the energy sector are an underrecognized yet significant source of greenhouse gas (GHG) emissions. At PT PLN (Persero) UID Kalselteng-the main electricity provider for South and Central Kalimantan-routine administrative and technical activities contribute to emissions primarily through electricity consumption, fossil fuel vehicle use, and solid waste generation. Aim: This study aims to identify and quantify the main emission sources from PLN’s office operations over a three-year period (2022-2024), and to propose actionable mitigation strategies aligned with PLN’s decarbonization targets and Indonesia’s national sustainability goals. Methodology and results: Using the 2006 IPCC Guidelines, emissions were calculated across three categories: electricity use, transportation fuel, and waste disposal. The analysis shows that electricity consumption is the dominant source, contributing an average of 6,447.56 tons CO₂-eq per year (83% of total emissions). This is followed by emissions from operational vehicles at 1,175.30 tons CO₂-eq (15.2%) and solid waste at 107.85 tons CO₂-eq (1.4%). Conclusion, significance and impact: These findings reveal that office-level emissions-particularly in energy utilities-are both substantial and symptomatic of broader structural inefficiencies in emission control. Addressing these is critical for advancing sustainability, as they significantly impact organizational carbon footprints. Accordingly, this study recommends four key mitigation strategies: (1) retrofitting offices with energy-efficient systems, (2) transitioning to electric vehicles, (3) implementing zero-waste-to-landfill policies, and (4) initiating localized tree-planting programs for carbon offsetting. Together, these measures support integrated sustainability efforts by reducing emissions, improving resource efficiency, and reinforcing PLN’s leadership in sustainable public utility operations across Indonesia and Southeast Asia.
