The discharge of surfactant-laden wastewater from the rapidly expanding laundry industry poses significant environmental risks, especially in densely populated urban areas. While constructed wetlands (CWs) and Eco-Enzyme technology have shown promise for surfactant remediation, their standalone application requires long hydraulic retention times (HRTs), limiting practical implementation. This study evaluated the efficacy of a novel integrated system combining a subsurface constructed wetland (SSFCW) with fruit peel-derived Eco-Enzyme to treat synthetic laundry wastewater. Over a 6-day treatment period, the combined system achieved a remarkable surfactant removal efficiency of 99.63%, reducing the concentration from 225 mg/L to 0.835 mg/L—well below the regulatory threshold of 3 mg/L. The synergistic degradation mechanism involves enzymatic hydrolysis via Eco-Enzyme lipase and protease activity, complemented by microbial mineralization in the wetland rhizosphere. This system maintains optimal environmental conditions, with a stable pH of 6.85-7.32 and a temperature of 30.9-35.2°C, supporting robust biological activity. These findings demonstrate that the integrated Eco-Enzyme/SSFCW system overcomes the limitations of conventional HRT approaches, offering a highly efficient, sustainable, and practical decentralized wastewater treatment solution for the laundry industry.

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.

Method: The research method involves collecting data from industrial machine sensors consisting of vibration signals, temperature measurements, and acoustic signals, followed by data preprocessing and feature extraction processes. The processed data are then used to train a deep learning-based diagnostic model, after which explainability methods such as SHAP or LIME are applied to analyze the contribution of each feature to the model’s prediction results. Model performance is evaluated using accuracy, precision, recall, and F1-score metrics. Results: The results indicate that the proposed deep learning model achieves better performance compared to conventional machine learning methods such as Support Vector Machine and Random Forest. Furthermore, the explainability analysis reveals that vibration amplitude, increases in machine component temperature, and anomalies in acoustic signals are the main factors influencing machine fault detection. Therefore, the proposed system not only improves the accuracy of machine fault diagnosis but also provides transparency in the decision-making process, thereby supporting the implementation of predictive maintenance in smart manufacturing environments.

The integration of Artificial Intelligence (AI) into educational settings, particularly in formative assessments, offers significant benefits in terms of personalized learning, real time feedback, and increased efficiency.
