This study investigates the relationship between Environmental, Social, and Governance (ESG) performance and corporate financial distress, with board gender diversity examined as a moderating variable. Using 96 firm-year observations from manufacturing companies listed on the Indonesia Stock Exchange (2022–2024), the analysis employs variance-based Structural Equation Modelling (SEM). The findings reveal that ESG performance does not exert a statistically significant effect on financial distress, and gender diversity does not moderate this relationship. These non-significant results constitute the central empirical contribution of the study, highlighting that ESG engagement and gender diversity have yet to translate into financial resilience in the Indonesian manufacturing context. The study underscores the importance of contextual factors—such as implementation costs, authenticity of ESG disclosures, and limited female representation on boards—in shaping the effectiveness of sustainability practices. The results provide theoretical implications for Stakeholder and Agency Theory and offer practical insights for managers, regulators, and investors in emerging markets.

Soil contamination by hydrocarbons, pesticides, heavy metals, and complex pollutants is rapidly increasing and degrading essential ecosystem functions. Physical or chemical treatments offer faster results, yet they are often costly, energy-intensive, and risk disrupting soil biological integrity without fully eliminating pollution sources. Microorganism-based bioremediation provides a more sustainable alternative by utilizing microbial metabolism to degrade or immobilize pollutants into less toxic and less mobile forms. This article presents a structured literature review on the roles and applications of microorganisms for bioremediation of contaminated soils, covering comparisons between single isolates and microbial consortia, dominant biological mechanisms, and ecological challenges in field application. A Systematic Literature Review approach was applied, using narrative synthesis and thematic clustering of national and international journals published between 2020 and 2025. The review indicates that single microbial isolates are commonly selected for specific pollutant targets, whereas microbial consortia are preferred for mixed or persistent contaminants due to metabolic synergy that enhances microbial adaptability and stepwise pollutant breakdown in highly polluted soils. Adaptive mechanisms such as EPS production and biofilm formation contribute to microbial resilience under stress and help retain contaminants within the soil matrix. Key challenges identified include inoculum stability under extreme conditions and limited microbial access to pollutants trapped in micro-soil pores. The findings highlight that microbial selection strategies must be tailored to pollutant characteristics and soil environmental conditions, while also emphasizing the potential of biofilm-based systems and organic carriers to support broader field implementation of microbial bioremediation.

Rapid infrastructure development in Indonesia poses significant environmental risks, necessitating effective control instruments like the Environmental Impact Assessment (AMDAL). This study analyzes the strategic role of AMDAL in supporting the achievement of Sustainable Development Goals (SDGs), particularly regarding water security, sustainable cities, climate action, and ecosystem conservation. Using a qualitative method with a literature review approach, this research evaluates regulations and academic sources from 2020 to 2025. The findings reveal that AMDAL serves as a critical preventive tool that aligns industrial activities with SDG 6, SDG 11, SDG 13, SDG 14, and SDG 15 through the internalization of ecological costs and strict mitigation hierarchies. Furthermore, AMDAL functions as an essential baseline data source for government monitoring. However, the study identifies substantial barriers to implementation, including a deficit in meaningful public participation, weak law enforcement that renders AMDAL a mere administrative formality, and regulatory dynamics post-Job Creation Law (UUCK) which shifted to a risk-based approach. The study concludes that while AMDAL is theoretically robust as a safeguard for sustainability, its practical implementation requires strengthening in transparency and supervision to effectively bridge economic interests with ecological preservation.

Zinc (Zn) is one of the most common heavy metal contaminants found in industrial wastewater and solid residues such as slag, electroplating waste, and metal ash. At excessive concentrations, Zn can cause environmental disturbances, including toxicity to aquatic organisms, disruption of microbial activity, and groundwater contamination. Long-term exposure may also lead to bioaccumulation and potential health risks to humans. This article presents a comprehensive literature review that discusses the chemical properties of Zn, its environmental behavior, and the development of recent treatment technologies within the last five years. Several techniques, including adsorption using modified or composite materials, biosorption utilizing microalgae and agricultural biomass, as well as solidification–stabilization with amendment agents such as biochar or iron-sulfide compounds, are evaluated and compared. The literature indicates that no single treatment method is universally effective for all waste types; therefore, hybrid or integrated treatment systems are considered more efficient and sustainable. Based on the reviewed evidence, this study proposes an engineering concept that emphasizes environmental safety, cost-effectiveness, and industrial applicability.

This study investigates the impact of green accounting practices on corporate environmental performance, with a focus on manufacturing firms in Indonesia. Green accounting, which involves the identification, measurement, and reporting of environmental costs, is increasingly recognized as a strategic tool for enhancing corporate accountability and sustainability. However, in developing countries, its implementation remains limited and fragmented. Using a qualitative approach, this research explores how green accounting mechanisms are integrated into corporate decision-making processes and how they influence key environmental performance indicators such as energy efficiency and waste reduction. Data were collected through semi structured interviews with environmental and finance managers from five companies actively participating in the PROPER environmental rating program. Thematic analysis revealed that firms with advanced environmental accounting practices achieved higher energy savings and waste reduction outcomes, as well as superior PROPER ratings. These improvements are directly linked to the strategic use of environmental data in operational planning and investment decisions. Nonetheless, challenges such as the lack of technical guidelines, insufficient human resources, and the absence of standardized frameworks remain significant barriers to broader adoption. The study contributes to the growing literature on sustainability accounting in emerging economies and offers practical implications for policymakers and corporate practitioners seeking to institutionalize green accounting as part of sustainable business governance.

This study emphasizes the importance of integrating technical, social, and environmental aspects in bridge planning, so that the resulting design can provide a safe, efficient, and sustainable solution. Thus, bridge planning is not merely a technical process, but also a development strategy that supports connectivity and community welfare.

Extraction is a crucial stage in obtaining bioactive compounds from natural materials that have potential as medicinal, cosmetic, or nutraceutical ingredients. Among the various extraction methods available, maceration remains one of the most widely used techniques due to its simplicity, cost-effectiveness, and ability to maintain the stability of active compounds. The maceration process involves soaking powdered plant material in a suitable solvent at room temperature for a certain period, accompanied by periodic stirring to facilitate the diffusion of active compounds into the solvent. This method is particularly effective for extracting polar and semi-polar compounds such as flavonoids, phenolics, and essential oils that are sensitive to heat. The review shows that the effectiveness of maceration is influenced by several key factors, including the type and concentration of solvent, particle size of the material, duration of soaking, and stirring frequency. The use of ethanol with higher concentrations generally yields greater extract recovery and higher levels of active compounds. In addition, maceration is considered environmentally friendly because it requires no excessive heating and can employ safe, natural solvents. Therefore, despite the development of advanced extraction technologies, maceration remains a relevant, practical, and efficient method for phytochemical extraction, especially in laboratory research and small-scale herbal industries.

Dependence on chemical fertilizers has caused a decline in soil quality, groundwater contamination, and rising agricultural production costs due to unstable fertilizer prices. In recent years, frequent fertilizer crises have revealed the fragility of reliance on inorganic fertilizers within the national agricultural system. Hence, a transformation toward environmentally friendly and sustainable agriculture is urgently required. This study employed a scoring technique to analyze field observation data, which were narrated based on the written methodology. Respondents’ answers were categorized and classified according to their assumptions or opinions, with scores determined using a Likert scale. The Likert scale measures attitudes, opinions, and perceptions of individuals or groups regarding specific social phenomena. The results showed that key driving factors—such as affordable fertilizer prices, support from agricultural extension workers, and social encouragement from the community—achieved scores above 82%. This finding indicates that external conditions are quite favorable for promoting the use of organic fertilizers. However, major challenges remain, including the limited availability of organic fertilizers in the field and farmers’ long-standing dependency on chemical fertilizers. To address these challenges, it is essential to enhance the market availability of liquid organic fertilizers (POC) through collaboration between producers and farmer groups. Continuous technical assistance should be provided, including demonstration plots that display tangible improvements in rice yields using POC. Furthermore, government support in the form of targeted subsidies or special incentives for farmers transitioning to organic fertilizers is vital, while strengthening the role of farmer groups and agricultural extension workers as catalysts for the adoption of environmentally friendly innovations.
