Rapid urbanization, especially in developing countries, has worsened spatial inequality and environmental degradation, impacting vulnerable urban communities living in informal settlements with limited access to services and increased environmental risks. This study examines the role of spatial planning law in promoting social justice and environmental protection in urban areas, particularly for marginalized populations. While spatial planning laws have the potential to promote equity and sustainability, inconsistent enforcement and inadequate evaluation mechanisms reduce their effectiveness. Using a qualitative legal analysis approach, the research reviews statutory frameworks, urban planning documents, and case studies to assess the practical application of these laws. Findings show that integrating spatial planning laws with social justice and environmental sustainability principles can enhance the living conditions of vulnerable communities by ensuring equitable resource access and reducing exposure to environmental hazards. However, fragmented legal frameworks, weak enforcement, and a lack of participatory planning hinder their impact. Comparing with traditional urban planning, social justice-oriented spatial planning provides more sustainable outcomes by prioritizing equity and environmental protection. The study recommends policy reforms to strengthen law enforcement, encourage inclusive decision-making, and integrate social justice and sustainability into urban planning frameworks. Further research is needed to assess the long-term impacts and role of these laws in achieving equitable urban development.

The rapid development of urban areas has created significant challenges in mobility, particularly the increasing use of private motor vehicles, which contributes to traffic congestion, air pollution, greenhouse gas emissions, and a decline in the quality of urban life. Sustainable transportation emerges as a solution by emphasizing the balance between environmental, social, and economic aspects through the use of eco-friendly modes such as public transport, walking, and cycling. However, the adoption rate of these modes remains relatively low due to perceptions of convenience, car-oriented culture, and limited environmental awareness. This study aims to analyze the implementation of sustainable transportation education as a strategy to raise urban communities’ awareness of eco-friendly mobility. The research employs a qualitative approach with descriptive analysis based on literature studies. Findings indicate that the use of digital media, social campaigns, and community participation plays a crucial role in shaping positive attitudes, new social norms, and pro-environmental behavior. Effective education not only delivers information but also builds values, norms, and new habits that support sustainable mobility. Furthermore, multi-stakeholder collaboration among government, communities, and the private sector strengthens the effectiveness of educational programs. Evaluation results show that continuous education enhances transportation literacy, ecological awareness, and urban quality of life. Thus, the implementation of sustainable transportation education serves as a strategic foundation for transforming urban mobility toward a healthier, inclusive, and equitable transportation system.

This study aims to understand how green accounting practices are constructed as a social reality within organizations and how environmental awareness develops through social interaction, organizational values, and culture. The research adopts an interpretive qualitative approach within the social construction paradigm (Berger & Luckmann, 1966). Data were collected through in-depth interviews, participant observation, and document analysis in organizations that have implemented sustainability reporting. The analysis employed an interpretive thematic approach to uncover the meanings underlying environmental accounting practices. The findings indicate that green accounting functions not only as a technical reporting instrument but also as a mechanism for shaping organizational moral and ecological awareness. Environmental awareness is constructed through three main stages: the externalization of sustainability values by leadership, objectivation through policies and reporting systems, and internalization within work behavior and organizational culture. Participatory, reflective, and innovation-oriented organizational cultures strengthen the substantive implementation of green accounting, whereas bureaucratic structures tend to produce symbolic practices or greenwashing. Theoretically, this study reinforces the view that accounting is a social practice that both shapes and is shaped by collective consciousness (Hopwood, 1992; Gray, 2010). Practically, the findings highlight the importance of visionary leadership and social learning spaces in fostering a sustainability-oriented organizational culture. Thus, green accounting is understood as a social process that plays a strategic role in realizing ethical, sustainable, and environmentally responsible organizations.

This research specifically aims to describe the application of green financing practices, assess financial performance conditions, and analyze bank profitability during the 2020–2024 period. The study employs a descriptive quantitative approach using secondary data on green financing distribution, financial performance indicators such as the Capital Adequacy Ratio (CAR), Non-Performing Loans (NPL), and Loan to Deposit Ratio (LDR), as well as profitability measured through Return on Assets (ROA). The findings indicate that the implementation of green finance has the potential to enhance long-term financial stability and improve profitability in the banking sector. This study implies that expanding green financing can serve as a relevant and sustainable business strategy for the banking industry while simultaneously supporting national sustainability and environmental development objectives.

The plastic recycling industry generates wastewater that poses a potential threat to aquatic environments if not managed optimally. Performance evaluation of Wastewater Treatment Plants (WWTP) is typically conducted partially by comparing outlet parameters against effluent standards, often failing to depict water quality conditions holistically. Therefore, this study employs the Water Quality Index (WQI) approach using the Canadian Council of Ministers of the Environment (CCME) method to evaluate the performance of PT X's WWTP in East Java. This research utilized secondary data from inlet and outlet wastewater quality tests over 23 months (January 2024–November 2025), covering 10 parameters. Analysis was conducted by calculating removal efficiency and determining factors F1 (scope), F2 (frequency), and F3 (amplitude) as the basis for the WQI-CCME calculation. The results indicate that the WWTP achieved high efficiency (>80%) in reducing dominant parameters such as TSS, TDS, BOD, and COD. However, violations of effluent standards were still observed in certain parameters. The obtained WQI-CCME value was 69,30, categorized as "Fair" with a moderate level of violation. These findings demonstrate that although the WWTP meets regulatory standards, the WQI-CCME approach provides a more comprehensive assessment of performance. Optimization of advanced treatment units is recommended to improve effluent quality and sustainable WWTP performance.                                                                   

This study comprehensively evaluates the quality of biomass briquettes produced from blends of coconut shell charcoal and sengon sawdust, using both carbonized and non-carbonized materials. Composite briquettes were fabricated with varying compositions and characterized through proximate analysis, calorific value, density, and burning rate measurements to determine their suitability as solid fuel. The results indicate that adding non-carbonized sawdust increases volatile matter content and burning rate but reduces the calorific value of the briquettes. In contrast, incorporating up to 10% carbonized sawdust significantly improves the calorific value to 6119.2 cal/g, approaching that of pure coconut shell charcoal (6352.2 cal/g), while maintaining a relatively high burning rate. Briquettes containing carbonized sawdust also exhibit low ash content, below 3%, and moisture content under 8%, meeting standard solid fuel quality requirements. These findings demonstrate that a strategic combination of carbonized and non-carbonized materials can produce hybrid biomass briquettes with optimized thermal performance, providing a promising, sustainable, and environmentally friendly alternative fuel for domestic and industrial applications.
