Abstract. Stunting remains a major public health issue in Indonesia, necessitating health promotion and prevention efforts through health education. The purpose of this study was to assess the effectiveness of leaflets in health promotion to prevent stunting in mothers with toddlers. The method used was a literature review with the PRISMA approach, by searching for articles in the Google Scholar, Garuda, PubMed, and Neliti databases using the keywords "stunting," "leaflet," "health promotion," and "health education." Of the 55 articles found, 16 met the inclusion criteria for analysis. The results of the analysis showed that the use of leaflets can improve mothers' understanding and attitudes regarding stunting prevention, including knowledge about balanced nutrition, exclusive breastfeeding, complementary feeding, and the First 1000 Days of Life (HPK). Leaflets were considered practical, easy to understand, and can be used repeatedly as a means of public health education. The conclusion of this study states that leaflets are effective for use in health promotion as a measure to prevent stunting in community nursing practice.

Organizational psychology plays an important role in understanding individual and group behavior within organizations, particularly in educational contexts. Its application can help improve the effectiveness of educational institution management by strengthening key aspects such as work motivation, leadership, communication, and a conducive work environment. By understanding these aspects, educational organizations can develop more effective work systems, enhance the performance of educators, and create a positive and productive organizational culture. However, research on organizational psychology in educational settings remains fragmented and often focuses on specific variables separately. This limits a comprehensive understanding of how these factors interact to influence overall organizational performance. Therefore, a more integrative and comprehensive review is needed to synthesize previous findings. This study aims to review and synthesize existing literature on organizational psychology in educational organizations, with a particular focus on the roles of motivation, leadership, and work environment in improving organizational effectiveness. The findings are expected to provide a more holistic understanding and serve as a basis for developing strategies to enhance the performance of educational organizations in the future.

Typhoid fever remains a significant diagnostic challenge, particularly regarding the interpretation of Widal test results which are often affected by antibody persistence. This study aims to analyze the variations in Widal antibody titers among students at Universitas Muhammadiyah Purwokerto, focusing on the time interval since their last confirmed infection. Using a cross-sectional design, serum samples from 24 students were analyzed through the semi-quantitative slide agglutination technique to detect Salmonella typhi O and H agglutinins. The findings indicated that anti-Salmonella O titers could persist up to 1:320 in individuals with an infection history of more than one year. In contrast, anti-Salmonella H was only identified in more recent infections (less than a year) with a lower titer of 1:80, and was undetectable in samples from infections exceeding one year. These results demonstrate that O antigens remain detectable in the blood significantly longer than H antigens. This study suggests that the duration since the last infection is a critical factor in the screening and validation of Widal test results. Accurate identification of these titer variations is essential for clinical laboratory technologists to provide more precise diagnostic data and support effective clinical management.

Hypertension is a global health problem that requires ongoing management, one of which is through a low-salt diet. However, many people with hypertension do not adhere to this diet due to a lack of information and understanding of the disease's risks. The Health Belief Model (HBM) can be utilized as a health education method to encourage hypertension management behavior using leaflets. This study aims to analyze the application of the HBM theory in the use of leaflets to increase knowledge about a low-salt diet among hypertensive patients in the community. The method used in this study was a literature review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines through the steps of identification, screening, eligibility assessment, and selection of articles until 16 articles were obtained that met the inclusion criteria. The results of this study indicate that leaflets are effective in increasing knowledge about a low-salt diet, adherence to health behaviors, and blood pressure control for people with hypertension. The components of the HBM, such as perceived susceptibility, perceived severity, perceived benefits, perceived barriers, and cues to action, play a role in shaping risk perceptions and encouraging changes in health behavior. Therefore, leaflets based on HBM are highly recommended as a form of promotional and preventive intervention in nursing practice in the community because they are easy to use, low cost, and support self-management of hypertension.

The development of Islamic banking activities in Indonesia currently is not matched by adequate understanding among students, particularly regarding the rights and obligations of customers, Sharia contract literacy, and consumer protection mechanisms. This Community Service Activity aims to enhance the understanding of Muara Bungo University students regarding customer rights and obligations, complaint procedures, basic sharia contract literacy, prevention of detrimental service practices, and the resolution process for sharia banking consumer disputes. The activity was attended by 50 students from all faculties and department, conducted using the Participatory Action Research (PAR) approach through the stages of problem identification, planning, implementation with interactive lecture methods, and evaluation. The results of the activity showed a significant increase in understanding, marked by the growing awareness of participants regarding the rights and obligations of customers, understanding of Islamic banking contracts, as well as the ability to comprehend consumer protection concepts and the dispute resolution process effectively. Consumer protection literacy education has proven to have a positive impact on students in preparing themselves to face the banking world, both in the context of employment and business in the future.

Digital transformation in Human Resource Management (HRM) has shifted the organizational paradigm from an administrative function to a strategic function focused on adaptive and sustainable human resource development. This study aims to systematically review the integration of digital technology in HRM practices with particular emphasis on inclusivity and organizational sustainability. The method employed is a literature review analyzing various studies related to the implementation of Artificial Intelligence (AI), big data analytics, and digital systems in recruitment, competency development, and employee performance evaluation. The findings indicate that digital transformation enhances operational efficiency, decision-making quality, and workplace flexibility. However, the adoption of digital technology also creates ethical challenges, including algorithmic bias, unequal access to technology, and concerns regarding employee data privacy. Therefore, the implementation of Equity, Diversity, and Inclusion (EDI) principles is essential in developing fair and inclusive HRM systems. Furthermore, continuous learning cultures and flexible work models have proven effective in supporting employee well-being while strengthening organizational resilience in facing global changes. This study emphasizes the importance of synergy between technological innovation, ethical leadership, and sustainability in building HRM systems that are responsive to the future of work.

This study aims to analyze the role of organizational communication in improving organizational performance using a systematic literature review approach with a descriptive qualitative method. The data were obtained from various relevant scientific literature sources, including national journals and academic articles discussing organizational communication and performance. The results indicate that organizational communication plays a significant role in enhancing performance through effective vertical and horizontal communication patterns, clarity of information flow, and improved work coordination. In addition, organizational communication contributes to building harmonious working relationships, increasing motivation, and strengthening organizational commitment. Leadership plays a crucial role in managing communication effectiveness within the organization. However, communication effectiveness is also influenced by supporting and inhibiting factors, such as work environment, communication skills, and differences in individual perceptions. Therefore, organizations need to manage communication strategically to achieve optimal performance. This study provides theoretical contributions to the development of organizational communication studies and practical implications for organizations in improving communication effectiveness.

This community service activity aimed to improve students’ knowledge and awareness regarding the dangers of vaping, free sex, and drug abuse among adolescents. The activity was conducted at SMAN 3 Lamongan on April 13, 2026, involving 28 students. The implementation method consisted of health counseling through material presentation using presentation media, interactive discussions, and evaluation using pretest and posttest methods. The materials covered the dangers of vaping and smoking, risky sexual behavior, and drug abuse. The results showed an increase in students’ knowledge after the counseling session. The average pretest score was 84.24%, which increased to 98.57% in the posttest. The Wilcoxon test result showed a significance value of 0.000 (<0.05), indicating a significant difference between pretest and posttest scores. This demonstrates that health education was effective in improving students’ knowledge related to healthy lifestyles and prevention of risky behaviors. Therefore, this activity is expected to serve as a promotive and preventive effort in shaping a healthy young generation that is aware of the importance of maintaining personal health

This Community Service (CS) initiative was executed collaboratively by faculty members from five universities—Universitas Pamulang, Universitas Presiden, Universitas Trisakti, Universitas Pembangunan Jaya, and Universitas Borobudur—in Kasomalang Kulon Tourism Village, Subang Regency, West Java, on April 17, 2026. This initiative aimed to instruct village leaders, as prospective catalysts for change in waste management and renewable energy, on the technique for converting plastic trash into pyrolysis-derived alternative fuel and the Triboelectric Nanogenerator (TENG) energy harvesting technology. This activity addresses the critical issues of plastic waste pollution and the exhaustion of fossil fuel reserves. Annually, almost 8 million tonnes of plastic waste infiltrate the oceans, yet merely 9% of all plastic ever manufactured is effectively recycled. The collaborative effort encompassed Electrical Engineering, Computer Systems, Petroleum Engineering, Information Systems, Product Design, and Agrotechnology. The instructional techniques employed comprised lectures and conversations. The activity's results indicated that participants acquired a thorough comprehension of pyrolysis mechanisms, the principles of TENG energy conversion, and its possible applications at the village level. Despite the absence of direct implementation, the cadres shown significant motivation to facilitate technology adoption inside their communities. This PKM model demonstrates that interdisciplinary collaboration across universities is effective in providing innovative technological education to rural populations.

Local wisdom is an important part of a nation's cultural identity, but its existence is beginning to be marginalized in the midst of modernization. The Kajang Indigenous People in Bulukumba Regency, South Sulawesi, are one of the communities that still maintain their traditional values through a customary legal system called Pasang ri Kajang. This community service activity aims to introduce the potential of Kajang cultural tourism to students as an educational effort in instilling the values of local wisdom. The partners in this activity are the Kajang indigenous people and local traditional leaders, including Ammatoa as the traditional leader. The activity is carried out with a participatory and educational method based on direct experience, which involves students in observation, discussion, and reflection on local culture. The results of the activity showed an increase in student knowledge by 31% and a significant change in attitudes towards the preservation of local culture, where more than 80% of participants showed an appreciative attitude towards the values inherited by the Kajang community. This activity also received a positive response from the local community because of its approach that respects traditional values. In addition, this activity produces several outputs, such as cultural introduction modules, activity documentation, and draft service articles. This activity shows that student involvement in the introduction of local culture can be an effective strategy in building multicultural awareness and preserving the nation's cultural heritage.

This study examines the urgency of foreign nationals' (WNA) legal status and visa compliance in the vehicle rental business in Bali, as well as its impact on business disputes involving local entrepreneurs. The increasing number of international tourists visiting Bali has spurred the growth of vehicle rental services, yet it has also given rise to illegal practices by foreign nationals such as misuse of tourist visas for commercial purposes, tax evasion, and unfair business competition. This research adopts a normative juridical method using statute, conceptual, and case approaches, referring to key legal documents including Law No. 6 of 2011 on Immigration, Law No. 6 of 2023 on Manpower, Ministerial Regulation No. 21 of 2016, and Bali Regional Regulation No. 5 of 2016 on Tour Guiding. The findings highlight the vulnerability of rental contracts under Article 1548 of the Indonesian Civil Code, risks of breach of contract, and widespread violations of the Electronic Traffic Law Enforcement (ETLE) system, the penalties of which are imposed on rental owners. Nationality disparities and weak immigration oversight further undermine the effectiveness of law enforcement. This study concludes that legal protection for local business actors relies heavily on the legal clarity of WNA status, the appropriateness of 1 visa categories, and strong inter-agency coordination. The novelty of this research lies in integrating legal analysis of WNA legitimacy with a dispute resolution framework specific to the vehicle rental sector in Bali’s tourism landscape a perspective that has been largely overlooked in prior studies. The recommendations include strengthening rental contracts, enhancing coordinated supervisory mechanisms, and harmonizing civil and criminal law to establish a stronger deterrent effect.

Decentralisation and democracy are two interrelated concepts in governance reform, particularly in improving the effectiveness of regional development. Decentralisation is often seen as an instrument to strengthen democracy by bringing the decision-making process closer to the people. This study aims to analyse the trend of research publications on decentralisation in Indonesia using a bibliometric analysis approach. The articles used in this study were obtained from Scopus data. From 472 articles found in the scopus database between 1999 and 2025. The selected articles were then managed using biblioshiny and Vosviewer software. The results show that publications related to decentralisation have fluctuated over the last 27 years. The article with the most citations entitled Decentralisation and Democracy in Indonesia: A Critique of Neo-Institutionalist Perspectives has 213 citations. Meanwhile, the highest affiliation shows that the University of Indonesia is the institution with a total of 25 publications. The mapping of articles based on the relationship between keywords (co-occurance) is formed into 8 clusters, each cluster describes topics that are often discussed in decentralisation-related literature such as Indonesia, decentralization, democracy, local government, governance approach, election, Asia and southeast Asia.

This research investigates how Environmental, Social, and Governance (ESG) practices influence the tax liabilities of consumer cyclical companies in Indonesia between 2020 and 2024. By employing the Effective Tax Rate (ETR) as a proxy for tax burden, the study analyzes 160 data points from 32 purposively selected firms. Utilizing a Fixed Effect Model for panel data regression, the empirical results indicate that superior ESG performance significantly correlates with a higher ETR. This suggests that corporations with higher sustainability transparency tend to exhibit better tax compliance and avoid aggressive tax avoidance schemes. Grounded in stakeholder and legitimacy theories, these findings underscore that ethical ESG adoption strengthens public accountability and enhances the integrity of corporate governance within the Indonesian capital market.

 The rapid adoption of smartphones among Indonesian digital natives has increased reliance on biometric authentication systems. However, empirical evidence regarding the relationship between user satisfaction and security risk awareness remains limited, particularly in developing-country contexts. This study investigates the behavioral dynamics of biometric security perception among 266 respondents, consisting of 221 high school students and 45 university students in Indonesia. A Python-based computational pipeline incorporating Akaike Information Criterion (AIC) validation and 1,000-iteration stochastic bootstrapping was employed to evaluate nonlinear behavioral patterns using Polynomial Regression and Ordinary Least Squares (OLS) multivariate analysis. The results confirm the existence of a nonlinear Security Paradox. While the overall population demonstrates a positive quadratic trajectory, the university student group exhibits a concave-down parabolic relationship (a=−0.0460), indicating a decline in perceived utility beyond a specific security threshold. The identified behavioral breaking point occurs at X≈5.45 (95% CI: 2.99–20.77), suggesting that excessive security hardening may reduce perceived usability and increase cognitive friction. Furthermore, the ablation analysis reveals that security risk awareness (p<0.001) is the strongest predictor of user satisfaction, exceeding the influence of daily usage intensity. Segment-level analysis further demonstrates behavioral divergence between respondent groups. High school students exhibit relatively uniform satisfaction toward biometric systems, whereas university students display greater variability and more critical perceptions regarding authentication friction. These findings indicate that highly rigid security configurations may become less effective for users with higher digital literacy and risk awareness. This study contributes a computationally validated behavioral framework for understanding security–utility trade-offs and provides a conceptual foundation for developing adaptive, user-centric, and friction-aware biometric authentication systems.

Management psychology is an approach that plays a crucial role in understanding individual and group behavior within organizations, particularly in the ever-evolving educational and work environments. The application of psychological principles to management practice is believed to improve performance, leadership effectiveness, and create a more conducive work and learning environment. This study aims to examine the development of trends, approaches, and key findings in the study of management psychology through a literature review. Furthermore, this study also seeks to answer two research questions: (1) how have management psychology research trends developed over the past five years, and (2) what are the key findings in the educational and organizational contexts. The method used is a qualitative approach by searching various literature sources through the Google Scholar and Publish or Perish (PoP) databases, using the keyword "management psychology." Of the 20 articles found between 2021 and 2026, five were selected as the most relevant for further analysis. The study results indicate three dominant themes: the role of management psychology in education, the influence of motivation and leadership on performance, and its contribution to the organizational adaptation process. The conclusions of this study confirm that integrating psychological aspects into management plays a crucial role in increasing organizational effectiveness. Therefore, further research is recommended to empirically examine the relationship between psychological variables and a broader scope.

The flash floods that struck Aceh Tamiang caused infrastructure damage and contaminated clean water sources, making it difficult for residents to obtain potable water. This situation increases the risk of water-borne diseases and worsens the post-disaster situation. This research aims to develop a large-scale, simple water filtration prototype as an emergency response solution that is effective, economical, and easy to implement by affected communities. The methods used include field observation, water sampling, testing simple physical parameters (turbidity, color, odor, and pH), and designing a gravity-based, multi-stage filtration system without electricity. The prototype uses a combination of filter media such as gravel, silica sand, activated charcoal, and natural fibers in a drum system. Test results show a decrease in turbidity levels from 150–300 NTU to 5–15 NTU after the filtration process, as well as an increase in pH to near neutral. The filtered water is declared suitable for sanitation and consumption after undergoing a further disinfection process. In addition to implementing the technology, this research also includes public education regarding the selection of safe water sources and maintenance of the filtration system. Based on these results, this large-scale simple water filtration prototype is effective as an appropriate technological solution in handling the post-disaster clean water crisis and has the potential to be replicated in other flood-prone areas.

This research is motivated by the low speaking ability of elementary school students which is characterized by a lack of confidence, difficulty in expressing opinions in a coherent manner, and the lack of students' ability to express information clearly in learning Indonesian. These problems show that the learning that takes place has not fully provided opportunities for students to actively practice speaking skills. This research aims to Develop a booklet  based on Student Worksheets (LKPD) on interview text materials to support the speaking skills of grade IV elementary school students. The method used is research and Development with a 4D model which includes the define, design, and Develop stages. At the Development stage, the product is validated by media experts and subject matter experts to assess the feasibility level of the LKPD booklet  Developed. The results of the study showed that the LKPD booklet  obtained a feasibility percentage of 91.17% in the media aspect and 90.32% in the material aspect with a very feasible category. These results show that the LKPD booklet  Developed has met the eligibility criteria both in terms of appearance and content as teaching materials for learning Indonesian language in elementary schools. However, this research is still limited to the product validation stage, so further research is needed through field trials to determine the effectiveness of LKPD booklet s in improving students' speaking skills in more depth.
