This study aims to examine the effect of working capital efficiency and leverage on profitability and its implications for firm value in manufacturing companies listed on the Indonesia Stock Exchange (IDX) during the 2020–2025 period. The post-COVID-19 pandemic condition has increased operational risks for manufacturing companies due to fluctuations in interest rates, exchange rates, cash management, inventories, and receivables. Therefore, companies are required to implement more effective financial strategies to maintain competitiveness. Profitability is positioned as an intervening variable because previous studies showed inconsistent results regarding the relationship between working capital efficiency, leverage, profitability, and firm value. This research uses a quantitative approach with path analysis to examine direct and indirect relationships among variables. The population consists of all manufacturing companies listed on the IDX, while the sample includes 45 companies selected from 270 firms using purposive sampling based on specific criteria, such as consistent listing and financial performance. The results indicate that working capital efficiency has a significant positive effect on profitability, leverage has a significant negative effect on profitability, profitability significantly increases firm value, and profitability fully mediates the effect of working capital efficiency and leverage on firm value. These findings provide theoretical and practical implications for managers and investors in financial decision-making.

The waste problem in Indonesia has now reached a critical stage and has become an increasingly serious environmental issue. The ever-increasing volume of waste is not being managed effectively, leading to various negative impacts, particularly environmental pollution. This study aims to examine the state of waste management in Indonesia and its impact on water pollution from the perspective of the Sustainable Development Goals (SDGs). The method used is descriptive qualitative research through a literature review utilizing various sources such as journals, official reports, and legislation. The results indicate that the majority of waste originates from household activities, while management practices remain rudimentary, such as the “collect-transport-dispose” method and open dumping. This situation leads to waste accumulation, which contributes to water pollution, deteriorating environmental quality, and increased health risks for the community. Furthermore, suboptimal waste management also poses a challenge in achieving sustainable development goals, particularly regarding responsible consumption and access to clean water and sanitation. Therefore, improved efforts are needed through the application of the reduce, reuse, recycle (3R) principles, increased public awareness, and the active role of the government and the private sector in providing a sustainable waste management system. With the right measures, it is hoped that the waste problem in Indonesia can be reduced and the environment preserved.

Dengue Hemorrhagic Fever (DHF) remains a major public health problem in Indonesia, particularly in densely populated areas. Control efforts require accurate data and spatial analysis to understand disease distribution patterns. Geographic Information System (GIS) is an effective tool for visualizing case distribution and supporting surveillance and planning of control programs at the primary healthcare level. This study aims to describe the spatial distribution of Dengue cases based on medical record data and produce a geographic distribution map to support Dengue control efforts at the Puskesmas level. This study used a quantitative descriptive design with secondary data from medical records at Karangsari Health Center. The sample consisted of 255 DHF patients in 2025, selected using a total sampling technique. Data were processed through editing, geocoding patient addresses, and spatial analysis using QGIS software.The results showed 255 Dengue  cases in 2025 with fluctuating monthly trends, peaking in April and lowest in December. Case distribution was uneven and tended to cluster. High-risk areas accounted for 15.7%–21.2%, moderate-risk areas 9.8%–15.7%, and low-risk areas 7.1%–9.8%. Megu Cilik Village had the highest proportion of cases, while other villages were categorized as moderate and low risk. This pattern indicates that Dengue incidence is influenced by environmental conditions, vector density, host factors, rainfall, and Aedes aegypti presence. GIS provides clearer spatial visualization, helping identify high-risk areas and supporting targeted public health interventions.

This study aims to analyze the unemployment rate in Indonesia during the 2024–2025 period using a linear regression approach based on data from the National Labor Force Survey (Sakernas). The variables used include the labor force, employed population, labor force participation rate (LFPR), and open unemployment rate (OUR). The results show that the labor force increased from 149.38 million in February 2024 to 155.27 million in November 2025, followed by an increase in employed population from 142.18 million to 147.91 million in the same period. Meanwhile, the open unemployment rate decreased from 4.76 percent in February 2025 to 4.74 percent in November 2025. The analysis indicates that the increase in labor force accompanied by higher employment absorption contributes to reducing unemployment, although the decline remains relatively small. Overall, the regression results show that labor market dynamics are influenced by the interaction between labor force growth and the economy’s capacity to absorb labor.

This community service activity aimed to build a disaster preparedness culture through earthquake and tsunami simulation activities at Madrasah Aliyah Negeri 2 Suak Timah, West Aceh Regency. The activity was motivated by the high risk of earthquake and tsunami disasters in the coastal area of West Aceh and the limited understanding of students regarding disaster mitigation and evacuation procedures. This program was carried out through collaboration between the Regional Disaster Management Agency (BPBD) of West Aceh Regency, lecturers from the Civil Engineering Department of Teuku Umar University, the Samatiga Community Health Center, and the school. The methods used included education, socialization, demonstrations, and direct simulations regarding self-rescue actions during earthquakes and tsunamis. The simulation was conducted at Suak Timah Football Field as the evacuation gathering point. The results showed an increase in students’ and school members’ knowledge and preparedness in facing disasters. Participants were able to understand evacuation routes, perform self-protection actions, and follow evacuation procedures in an orderly and rapid manner. Evaluation results indicated that disaster mitigation understanding reached 85%, self-rescue ability 88%, accuracy in following evacuation routes 90%, discipline during simulation 92%, and participant involvement reached 95%. This activity also encouraged the formation of a disaster awareness culture and the emergence of active student roles as preparedness pioneers within the school environment. Therefore, disaster simulation proved to be an effective educational medium in improving the capacity and preparedness of school communities toward earthquake and tsunami risks.

This study examines the reproduction of social inequality in education through the theoretical framework of Pierre Bourdieu within a critical sociology perspective. The background of this research is rooted in the persistent gap in educational access, participation, and achievement among students from different social classes, which indicates that education does not always function as a tool for social mobility. The objective of this study is to analyze how mechanisms such as habitus, cultural capital, social capital, and the educational field contribute to sustaining inequality. This research employs a qualitative descriptive approach, with data collected through in-depth interviews, observations, and document analysis within an educational setting characterized by diverse socio-economic backgrounds. The findings reveal that students from higher socio-economic backgrounds tend to possess dominant cultural capital and habitus that align with institutional expectations, giving them a significant advantage in academic achievement. Conversely, students from lower socio-economic backgrounds face structural and symbolic barriers that limit their opportunities. The study also finds that educational practices, including teaching methods and evaluation systems, implicitly favor certain groups, thereby reinforcing inequality. The implications of this research highlight the need for more inclusive educational policies and practices that recognize diverse forms of capital and promote equal opportunities for all students. Ultimately, this study contributes to a deeper understanding of how education functions as a site of social reproduction rather than merely a neutral institution.  

This study aims to analyze public concerns regarding fast food consumption from the perspective of risk society, particularly among university students. The increasing consumption of fast food reflects shifts in consumption patterns influenced by globalization, practicality, and time efficiency. This research employs a qualitative approach through a literature review supported by interview data to strengthen the analysis. The findings reveal that fast food consumption is not solely driven by biological needs but also by practical, emotional, and social factors. Although students demonstrate a relatively high awareness of health risks associated with fast food, their consumption behavior persists as an adaptive response to structural conditions such as time constraints, accessibility, and academic pressures. From the perspective of risk society, this phenomenon illustrates a contradiction between risk awareness and everyday consumption practices. Risks produced by modernity are not entirely avoided but are negotiated and normalized in daily life. Therefore, fast food consumption cannot be understood merely as an individual choice but as a result of the interaction between structural factors, consumer culture, and social construction within modern society.

Flooding in Aceh has become a recurring phenomenon that cannot be understood solely as a natural disaster but also as a result of human activities within modern society. This study aims to analyze flooding in Aceh through the perspective of Ulrich Beck’s risk society theory, focusing on how modernization, environmental change, and development policies contribute to the production of risk. This research uses a literature review approach by examining scientific articles published between 2021 and 2026 from indexed national and international journals. The analysis was conducted thematically to identify patterns, similarities, and research gaps. The findings show that natural factors such as high rainfall and atmospheric conditions act as primary triggers, while human activities including land-use change, river sedimentation, and ineffective policies significantly intensify flood risks. Flooding is therefore categorized as a manufactured risk produced by modern development processes. In addition, the impacts are not limited to ecological damage but also affect social and psychological conditions of society. These results indicate that floods should be understood not only from a technical perspective but also from a social perspective. The study implies that flood management requires a comprehensive approach integrating environmental sustainability, social awareness, and evidence-based policy to reduce both the impact and sources of risk in a sustainable manner.

The development of transportation technology encourages companies to improve vehicle monitoring systems to be more effective and measurable, particularly in addressing speeding violations that can increase accident risks and reduce operational efficiency. This study aims to analyze the implementation and effectiveness of using a buzzer integrated with the Teltonika FMB910 GPS module as a vehicle speed warning indicator at PT. Lacak Cipta Aktual. This research employs a qualitative descriptive method with a case study approach, where data were collected through observation, interviews, and documentation during a one-month industrial internship and analyzed using the Miles and Huberman model, including data reduction, data presentation, and conclusion drawing. The results show that the system is capable of detecting overspeed conditions and automatically activating the buzzer when the vehicle speed exceeds the predefined threshold of 80 km/h. Based on logbook data, the system achieved a success rate of 93.9% in responding to overspeed conditions. The use of a buzzer is proven effective in providing immediate warnings to drivers, thereby improving driver awareness and speed control. However, the system still has limitations, particularly its dependence on GPS signal stability and vehicle electrical conditions. Overall, this study demonstrates that the integration of GPS and a buzzer provides a simple, effective, and cost-efficient solution to enhance driving safety and fleet management efficiency.

Bullying among adolescents is an aggressive behavior carried out intentionally, repeatedly, and involving an imbalance of power between the perpetrator and the victim. This phenomenon is an important issue because it can affect adolescents’ psychological well-being, social relationships, and academic achievement in both the short and long term. This study uses a literature review method by collecting and analyzing recent national and international studies regarding the causes, forms, and impacts of bullying. The findings indicate that bullying is influenced by internal factors, such as low empathy, poor self-control, negative self-concept, and the desire for social recognition. In addition, external factors also contribute, including parenting styles, peer influence, unfavorable school climate, and the development of social media that increases the risk of cyberbullying. The impacts of bullying are experienced not only by victims, who may suffer from low self-esteem, anxiety, depression, and social withdrawal, but also by perpetrators, who are at risk of developing persistent aggressive behavior and reduced empathy. Therefore, cooperation among families, schools, and communities is needed to prevent and address bullying effectively.

Amidst the rapid development of digital technology today, copyright plays a complex role as an instrument for protecting works and at the same time as a potential inhibitor of innovation. Protection of exclusive rights granted by the copyright protection system aims to provide economic incentives or financial benefits to the creator. However, in practice, it often creates limitations on creative freedom, especially in the context of derivative works, remixes, parodies, and other creative uses that are developing rapidly in the digital realm. This study aims to examine how the copyright legal system, both normatively and implementatively, affects the scope of movement of creative actors in producing innovation. Through a normative legal approach with a review of international and national literature, this study found that copyright protection is too strict and has the effect of freezing reactivity, especially if it is not balanced with clear fair use provisions. However, on the other hand, loose regulations will also risk ignoring the moral and economic rights of the original creator. Thus, a balance is needed between the protection of individual rights and the public interest within the framework of a legal system that is adaptive and inclusive of digital culture. The study recommends strengthening open licensing frameworks such as Creative Commons, as well as updating national copyright policies to ensure that legal systems do not hinder, but rather encourage, the growth of innovation and creative expression in the digital age.

Early marriage is a social phenomenon that remains prevalent in Indonesia and gives rise to various problems in family life. This article aims to analyze the implications of early marriage in light of the Code of Canon Law (CCL) Nos. 1055 and 1056 in the context of Catholic couples. This study employs a qualitative method with a descriptive-analytical approach through a literature review of books, scientific journals, and Church documents. The findings indicate that the CIC affirms marriage as a sacred covenant between a man and a woman oriented toward the bonum coniugum (the good of the couple), openness to children, and characterized by unity and indissolubility. In the context of early marriage, various implications were identified, such as emotional immaturity that triggers domestic conflicts, a high risk of divorce, low levels of education, and impacts on the health of mothers and children. Additionally, early marriage also indicates a weak understanding of the sacramental dimension and family responsibilities, including childrearing. Thus, CIC Nos. 1055 and 1056 provide an important normative foundation that marriage requires human, spiritual, and social maturity for the realization of a wholesome and prosperous Catholic family.

Schizophrenia is a severe mental disorder often accompanied by auditory hallucinations and has a significant impact on patients’ psychosocial functioning. This condition can reduce medication adherence, thereby increasing the risk of relapse. In this context, the role of caregivers is crucial in supporting treatment success. This study aims to describe psychiatric nursing care for patients with auditory hallucinations in improving medication adherence through caregiver involvement. The method used is a case study with a nursing process approach, including assessment, nursing diagnosis, planning, implementation, and evaluation. Interventions focus on hallucination management, psychoeducation, and caregiver involvement in care. The results show an increase in patients’ and families’ knowledge regarding the illness and its treatment, improved medication adherence, and enhanced patient ability to control responses to auditory hallucinations. Caregiver involvement has been shown to assist in supervision and providing support to patients. Therefore, comprehensive psychiatric nursing care through hallucination management, psychoeducation, and caregiver involvement is effective in improving medication adherence and controlling symptoms in patients with auditory hallucinations.

Clean and healthy living habits are an essential foundation in shaping a generation that is mindful of personal and environmental health. These habits need to be instilled from an early age, both at school and at home, so that they can become a sustainable part of students' lifestyles. This community service activity aims to improve the knowledge and skills of students at SD Negeri 1 Mertoyudan in consistently applying Clean and Healthy Living Behaviors (PHBS) in their daily lives. The implementation methods comprised three main approaches: interactive discussion-based education, a demonstration of proper handwashing techniques in accordance with WHO standards, and hands-on practice in maintaining personal hygiene. These approaches were chosen to ensure that students not only understand the concept of PHBS theoretically but are also able to apply it independently in real-life situations. The results of the activity showed a significant improvement in students' understanding of the importance of washing hands with soap at critical moments as a form of personal hygiene responsibility. Through a demonstrative approach that involved active student participation, participants were able to practice proper personal hygiene steps accurately and confidently. This activity is hoped to have a long-term impact in shaping students who are disciplined, responsible, and attentive to both personal and environmental health, while also serving as an effective preventive measure in reducing the risk of infectious diseases among school-age children.

The increasing spread of HIV/AIDS in Jayapura City requires immediate and sustainable preventive efforts, particularly through reproductive health education for adolescents. This program aimed to improve adolescents’ understanding of reproductive health, puberty changes, and behaviors that may increase the risk of HIV/AIDS transmission. The activity was conducted for adolescents participating in Sunday School at GKKD Buper Waena, aged between 10 and 15 years. The program was carried out in April 2025 through counseling sessions, question-and-answer activities, and focus group discussions. These approaches were chosen to provide participants with an interactive learning experience while also creating opportunities for them to share their personal experiences and perspectives related to reproductive health. A total of fifty adolescents participated enthusiastically in the activity. During the sessions, participants asked various questions that were answered directly by the speakers to clarify their understanding of reproductive health and risky behaviors. In addition, six focus group discussions were conducted to discuss participants’ personal experiences regarding puberty, friendships, dating, and behaviors such as kissing. The results of the activity indicate that reproductive health education can improve adolescents’ knowledge, awareness, and skills in maintaining personal health and avoiding behaviors that may increase the risk of HIV/AIDS transmission.

This study aims to examine the application of artificial intelligence (AI) in learning to write scientific papers and its impact on the level of originality of students in the Indonesian Language and Literature Education Study Program (PBSI) Semester VI at Bina Bangsa University. This study uses a qualitative method with a descriptive approach, which was conducted through reference searches and interviews with 30 of the total 35 students. The results of the study indicate that AI is utilized functionally as an aid in the writing process, such as compiling outlines, paraphrasing, developing ideas, and reviewing writing. Based on the interview results, the use of AI platforms is dominated by Chat GPT at 50%, followed by Perplexity at 27%, and Gemini.ai at 23%. These findings indicate that students do not rely on a single platform, but rather utilize various technologies adaptively according to their needs. In terms of discussion, the use of AI has a positive impact in the form of improved writing quality, time efficiency, development of creative ideas, increased digital literacy, and the provision of instant feedback. However, there are also challenges that arise, such as the potential for decreased originality, dependence on AI, the risk of violating academic ethics, information bias, and data privacy issues. Therefore, AI should be used as a tool, not a substitute for students' critical thinking skills. This research emphasizes the importance of using AI wisely, critically, and responsibly so that students can produce original, high-quality, and integrated scientific work in the digital age.

The implementation methods include interactive workshops, digital security trAIning, case simulations, and the use of a mini AI assistant as a preventive educational tool. Evaluation was conducted through pre-test and post-test assessments, participatory observation, and participant reflection. The results indicate an improvement in participants’ understanding of digital law, particularly regarding the provisions of the Law on Electronic Information and Transactions and its relevance to the Indonesian Criminal Code. In addition, participants’ technical skills in securing digital accounts, identifying phishing attempts, and responding to cyber risks have also improved. The use of AI has proven to enhance participation and contextual understanding. Overall, the program is effective in fostering legal awareness, improving digital protection capabilities, and shaping responsible behavior in cyberspace.

The development of digital technology has transformed trading patterns through the emergence of live shopping, a phenomenon that enables real-time interaction between sellers and consumers. Although it offers marketing efficiency, this model poses significant legal risks, including misleading information, promotional manipulation, and product non-conformity. This study aims to analyze legal certainty in consumer protection within live shopping transactions, examine the forms of business actors’ liability for consumer losses, and identify obstacles to regulatory implementation along with efforts to strengthen supervision.The research method employed is normative legal research using both a statute approach and a conceptual approach. The results indicate that legal certainty in consumer protection within this ecosystem is grounded in the integration of Law No. 8 of 1999 (Consumer Protection Law) as the lex generalis and Government Regulation No. 80 of 2019 (Electronic Commerce/PMSE) as the lex specialis, which recognizes the validity of real-time electronic contracts. The legal liability of business actors is strict liability in nature, in accordance with Article 19 of the Consumer Protection Law, and may also be construed as a tort (Article 1365 of the Civil Code) in cases involving distortion of visual information.However, the effectiveness of these regulations is hindered by the ephemeral nature of transactions and low levels of digital literacy. This study recommends the implementation of technology-based supervisory systems (suptech), strengthening the oversight function of platforms (PPMSE), and policy synchronization between the Ministry of Trade and the Ministry of Communication and Informatics in standardizing business actor verification to ensure the security of the digital commerce ecosystem.

Breast tumors are classified into two types, namely benign and malignant tumors, the latter commonly referred to as breast cancer. Breast cancer is one of the major health problems affecting women worldwide, including in Indonesia. According to WHO data in 2022, there were 2.3 million breast cancer cases with 685,000 deaths globally, while in Indonesia, 396,914 cases and 234,511 deaths were reported. The high incidence rate is exacerbated by low public awareness in recognizing early symptoms and performing early detection, resulting in 60–70% of cases being diagnosed at an advanced stage, supported by findings that 65.6% of female students still have a low level of knowledge. Female students were selected as research subjects because they are in a vulnerable reproductive age group and have an important role in increasing awareness of early detection, yet they still have limited knowledge. Based on this, this study aims to design a web-based early detection system for breast tumor risk using the Forward Chaining method, which functions as a tool to identify early symptoms, assess risk levels, and provide information on prevention and initial management. This study employed the method with the Expert System Development Life Cycle (ESDLC) model, consisting of the stages of assessment, knowledge acquisition, design, testing, and documentation, along with the Forward Chaining inference method.

Homemade food is increasingly dominating the choices of consumers who are oriented towards a healthy lifestyle. However, the belief that self-cooking is synonymous with food safety is not always supported by scientific evidence. This Narrative Review aims to build an in-depth thematic synthesis of the various dimensions of food safety risks that arise in the process of preparing healthy homemade food, ranging from biological and chemical contamination, to human behavioral factors as the main agents of contamination. The study was conducted against seven reputable sources of scientific literature published between 2010–2025, including observational, experimental, cross-sectional, and review studies. Four main themes were identified: (1) risky behaviors in the household kitchen as the dominant factor; (2) unexpected cross-contamination pathways including table salt as a vector; (3) chemical and biological contaminants hidden in "healthy" materials; and (4) evidence-based interventions that have been proven to be effective. This review confirms that homemade food safety is a behavioral issue, not just a technical one, so the intervention approach must be multidimensional and sustainable.
