This research seeks to define polycyclic aromatic compounds, which are chemical compounds consisting of fused aromatic rings that do not contain heteroatoms or substituents. Many of these compounds are known to be carcinogenic and are primarily produced through the incomplete combustion of carbon-containing fuels such as wood, coal, diesel, grease, and tobacco. Pure polycyclic aromatic compounds generally appear as colorless, white, or pale green solids that often develop a yellowish tint over time. These substances are commonly found in coal tar, crude oil, creosote, and tar deposits in industrial and urban environments. Despite their widespread occurrence and potential health risks, only a limited number of polycyclic aromatic compounds are utilized in industrial applications, including the manufacture of medicines, dyes, plastics, and pesticides. Furthermore, this research examines the distribution, persistence, and accumulation of these compounds in the environment, as well as their toxicological effects on human health, ecosystems, and long-term environmental sustainability.

This community service activity aims to assist the Ibu Jum Tempe Home Industry MSME in Bandar Lampung in implementing the process costing method as a more accurate, measurable, and efficient production cost calculation system. To date, MSMEs still use simple cost recording without a clear separation between raw material costs, labor, and factory overhead, so that product selling prices often do not reflect actual production costs. To address this problem, this activity was carried out through several stages, namely interviews to explore MSME needs and problems, production process observations, socialization regarding the importance of cost accounting systems, and direct training in the preparation and implementation of process costing. The results of the activity showed an increase in MSME owners' understanding of cost classification, unit cost calculations, and the preparation of production cost reports. After the process costing method was implemented, MSMEs were able to calculate costs more systematically and consistently, thus being able to determine more appropriate and competitive selling prices. In addition, the implementation of this method also contributed to increased cost management efficiency, transparency of financial information, and the managerial ability of business actors in making more appropriate decisions related to cost planning and control.

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.          

Acute Respiratory Infections (ARI) in the working area of Mulyorejo Public Health Center, where an aluminum factory is located, rank first among the ten most common diseases. This study aims to analyze the influence of sociodemographic characteristics and PM2.5 exposure on ARI complaints in the aluminum factory area of Payageli Village, Deli Serdang Regency. The cross-sectional observational study involved 160 housewives living within a radius of 10–1500 meters from the factory’s chimney. The analysis included univariate, bivariate, and multivariate methods. Results showed that 58.1% of respondents experienced ARI symptoms in the past month. The average ambient (outdoor) PM2.5 concentration measured from three sampling points was 12.3 µg/m³, which did not exceed the WHO standard (<15 µg/m³). The highest concentration was recorded in the southern direction (15.5 µg/m³). Bivariate analysis indicated that education (p = 0.010), direction of house location (p = 0.001), and indoor PM2.5 concentration (p = 0.006) were significantly associated with ARI. Multivariate logistic regression analysis showed that the most dominant factor influencing ARI was indoor PM2.5 concentration (p = 0.039), followed by education (p = 0.013) and direction of house location (p = 0.001). This study provides a scientific basis for air quality control and housing environment improvement to reduce the risk of environmentally related diseases in industrial zones.

Air pollution is an increasingly serious environmental issue in major cities, including Serang City. The decline in air quality due to motor vehicle emissions, industrial activities, waste incineration, and the reduction of green open spaces harms public health and the environment. Polluted air can cause respiratory problems, reduce the quality of life, and threaten urban ecosystems. This study aims to analyze the level of knowledge, perceptions, and behaviors of Serang City residents regarding air pollution, as well as assess their support for air pollution control policies. The methods used include a mixed-method approach through questionnaires, in-depth interviews, and participatory observation. The results of the study show that the community has a good understanding of the sources of air pollution, particularly vehicle and industrial emissions. They are also aware of the impact of pollution on health, especially for children and the elderly. However, the implementation of protective behaviors such as wearing masks is not yet consistent. Some positive behaviors have begun to develop, such as not burning trash and planting plants at home. Support for pollution control policies is also high. This study emphasizes the importance of continuous education, law enforcement, and collaboration between the government, society, and environmental communities in efforts to mitigate air pollution in Serang City.

The management of hazardous and toxic waste (B3) presents a major challenge in environmental governance, particularly in industrial areas such as Dumai City. Although regulations such as Dumai City Regional Regulation No. 5 of 2017 have been established, the evaluation of the local government’s collaborative capability in B3 waste control remains suboptimal. This study formulates the research question: how can the collaborative capability of the local government be evaluated in the implementation of Collaborative Governance within the B3 control program in Dumai City? The theoretical framework applied is the Collaborative Capability Evaluation Theory, which consists of four key dimensions: relational, structural, resource, and adaptive capacities. This research employs a qualitative case study approach using interviews, observations, and documentation techniques. The findings indicate that the local government’s collaborative capability is at a moderate level. The main barriers lie in inter-actor trust, inter-agency coordination, and limited resources. Strengthening the four dimensions of collaborative capability is essential to achieving effective, participatory, and sustainable environmental governance in Dumai City.

The use of Search-Based Software Engineering (SBSE) for optimizing software architecture has evolved from fully automated to interactive approaches, integrating human expertise. However, current interactive tools face limitations: they typically support only single decision-makers, confine architects to passive roles, and induce significant cognitive fatigue from repetitive evaluations. These issues disconnect them from modern, team-based software development, where collaboration and consensus are crucial. To address these shortcomings, we propose "ArchEvolve," a novel framework designed to facilitate collaborative, multi-architect decision-making. ArchEvolve employs a cooperative coevolutionary model that concurrently evolves a population of candidate architectures and distinct populations representing each architect's unique preferences. This structure guides the search towards high-quality consensus solutions that accommodate diverse, often conflicting, stakeholder viewpoints. An integrated Artificial Neural Network (ANN) serves as a preference learning module, trained on explicit team feedback to act as a surrogate evaluator. This active learning cycle substantially reduces the number of required human interactions and alleviates user fatigue. Empirical evaluation on two industrial case studies (E-Commerce System and Healthcare Management System) compared ArchEvolve to a state-of-the-art interactive baseline. Results indicate that ArchEvolve achieves statistically significant improvements in both solution quality and consensus-building. The preference learning module demonstrated over 90% accuracy in predicting team ratings and reduced human evaluations by up to 46% without compromising final solution quality. ArchEvolve provides a practical, scalable framework supporting collaborative, consensus-driven architectural design, making interactive optimization a more viable and efficient tool for real-world software engineering teams by intelligently integrating cooperative coevolutionary search with a preference learning surrogate.

The downstreaming of natural resources has emerged as a strategic policy implemented by the Coordinating Ministry for Economic Affairs to strengthen Indonesia’s economic independence and reduce reliance on raw commodity exports. Grounded in the philosophical foundation of Pancasila, this policy emphasizes the principles of economic equality, national sovereignty, and sustainability, in line with the overarching goals of national development. This study aims to analyze the role of industrial downstreaming policies in enhancing national economic self-reliance through the integration of Pancasila values. Substantively, downstreaming increases value-added production, boosts domestic investment, and facilitates job creation, particularly in the mineral processing and agro-industrial sectors. Moreover, the policy contributes to reducing economic vulnerability to global market fluctuations and aligns with the Pancasila principles of social justice and collective welfare. However, several challenges remain, including infrastructure readiness, environmental sustainability, and inclusive participation of small and medium enterprises (SMEs). The research indicates that the industrial downstream sector, as regulated by the Coordinating Ministry for Economic Affairs, plays a crucial role in realizing national economic autonomy, requiring its implementation to be aligned with Pancasila principles in order to balance economic progress with equity and sustainability.

The global economy is increasingly marked by volatility, uncertainty, and disruption, compelling organizations to adopt business agility as a means of survival and competitiveness. Conventional agility emphasizes speed, responsiveness, and innovation, yet often lacks the ethical foundation required for long-term sustainability. In contrast, Islamic economic thought, guided by Maqasid al-Shariah—the preservation of religion, life, intellect, lineage, and wealth—prioritizes justice, fairness, and social responsibility in economic activities. This study analyzes how the principles of Maqasid can be aligned with business agility to form an ethically grounded and adaptive business model. Employing a qualitative research design with a library research approach, the study synthesizes insights from existing literature on agility, Islamic economics, and Maqasid through thematic content analysis. The findings indicate that while agility strengthens resilience and competitiveness, it requires Maqasid as a moral compass to ensure value-driven adaptability. The integration of agility and Maqasid creates a synergy that enables Islamic enterprises not only to withstand global turbulence but also to differentiate themselves as ethical, sustainable, and competitive actors in the global market. This research therefore proposes a Shariah-compliant agility model that balances responsiveness with ethical accountability, offering theoretical contributions to academic discourse and practical implications for Islamic financial institutions, halal industries, and Shariah-based SMEs. The study also highlights the role of policymakers in developing supportive frameworks that foster innovation while safeguarding Shariah compliance. Overall, the study underscores that agility guided by Maqasid is not merely a survival strategy but a pathway to global leadership in ethical and sustainable business practices.

In the context of accelerating global economic volatility, organizations are increasingly required to adopt agile business models that enable them to remain competitive and resilient. Although business agility has been extensively discussed from structural and technological perspectives, the strategic role of Human Resources (HR) in shaping agile organizations and addressing the future of work remains insufficiently explored. This study aims to examine how HR contributes to organizational adaptability and resilience in uncertain environments by aligning human capital practices with agile frameworks. Using a mixed-methods approach, data were collected through surveys and semi-structured interviews with HR leaders and employees in industries most exposed to economic disruption, including finance, technology, and manufacturing. The findings reveal four critical dimensions of HR’s role: workforce flexibility achieved through reskilling initiatives and adaptive work arrangements; agile leadership development to enhance decision-making under uncertainty; prioritization of employee well-being and engagement as foundations of organizational resilience; and digital HR transformation leveraging analytics and artificial intelligence to strengthen efficiency and collaboration. These findings validate and extend the existing literature, demonstrating that HR is not merely a supporting or administrative function but a strategic driver of agility. The study concludes that by embedding HR strategies into organizational agility frameworks, companies can better navigate economic turbulence, enhance workforce adaptability, and secure long-term competitiveness in the global market.

Green accounting procedures have been adopted by numerous companies in response to the growing global focus on environmental responsibility. Nonetheless, monetary instability is still a major obstacle that can reduce productivity in Indonesia's manufacturing sector. The purpose of this research is to analyze industrial businesses listed on the Indonesia Stock Exchange from 2019 to 2023 and see how green accounting, financial crisis, and earnings management affect financial performance. The population in this study consists of 68 industrial sector companies, with a sample of 7 companies selected through purposive sampling based on 4 criteria. We used EViews software and Moderated Regression Analysis (MRA) for a quantitative approach. First, financial distress has a significant impact on financial performance. Second, green accounting has a significant positive effect on financial performance. Third, earnings management does not moderate the relationship between financial distress and financial performance. Fourth, earnings management does not moderate the relationship between green accounting and financial performance. With an Adjusted R-Square value of 79.73%, the study model has a high level of explanatory power. It may be used to explain the majority of the variation in financial performance. This shows that the constructed model is applicable and fits the empirical data well. Transparent reporting and real sustainability initiatives are still vital for improving company results, according to these results, as profits management methods do not change the impact of environmental and financial variables, which are important drivers of performance.

This study explores the integration of Islamic business management principles, blue economy concepts, and innovation strategies in the shrimp farming industry of Sidoarjo, Indonesia, to enhance global competitiveness. The research adopts a qualitative approach through literature review and thematic analysis of relevant sources, aiming to formulate a sustainable business model that harmonizes ethical, environmental, and economic dimensions. Findings reveal that applying sharia-based management—including mudharabah and musyarakah contracts, halal certification, and social responsibility through zakat and waqf—creates an equitable business ecosystem. Simultaneously, blue economy practices such as biofloc technology, waste utilization, and mangrove rehabilitation strengthen environmental sustainability and operational efficiency. Additionally, technological innovation through IoT-based monitoring, digital marketing, and traceability systems significantly improves productivity and market access. The synergy of these elements positions Sidoarjo shrimp as a distinctive product with ethical value, sustainability compliance, and premium market potential. This study suggests policy support for sustainable financing, technology adoption, and certification to scale up implementation and recommends future research to quantify its economic and ecological impacts.
