Abstract

According to the World Health Organization (WHO), musculoskeletal disorders (MSD’s) include conditions that affect muscles, joints, bones, and other supporting tissues and can cause pain and limited movement. Based on the report of the Indonesian Ministry of Health in 2020, approximately 16% of workplace diseases are caused by musculoskeletal diseases. This study aims to determine the relationship between nurses' work posture (REBA assessment results) and nurse demographic factors with the incidence of Musculoskeletal Disorders. This study is quantitative with a cross-sectional method with a population of 30 people with a total sampling technique on all nurses. When conducting REBA observations, interviews and questionnaires were used to obtain primary data. From the results of the study, the variables that influence reducing MSD’s are education with a P-value of 0.03. For the REBA method, which is a technique for assessing body posture at work, age, BMI, and length of service do not affect MSD’s. Education can provide knowledge about ergonomics so that nurses can overcome MSD complaints by carrying out work with a good working posture that can reduce MSD complaints that are not high on the pain scale.

Abstract

Stunting remains one of Indonesia’s major chronic nutritional problems and poses a serious threat to human resource development, particularly in vulnerable regions such as Maros Regency. Stunting reflects long-term nutritional deficiencies during the critical period of the first 1,000 days of life and is associated with adverse consequences on physical growth, cognitive development, health status, and future productivity. Data indicate that the prevalence of stunting in the working area of the Marusu Health Center increased to 4.1% in 2024, highlighting the need for more effective preventive strategies that address not only biological and nutritional factors but also behavioral and communicative aspects. This study aimed to analyze the relationship between interpersonal communication and stunting prevention and management behaviors at the Marusu Health Center, Maros Regency. An analytical observational design with a cross-sectional approach was employed. The study population consisted of 284 mothers with stunted children in the Marusu Health Center area. Based on sampling criteria and data collection during the study period, a total of 96 respondents were included in the final analysis using accidental sampling. Primary data were collected through face-to-face interviews using structured questionnaires, while secondary data were obtained from the Marusu Health Center and the local Health Office. Data analysis was conducted using Chi-Square tests and multivariate logistic regression to identify significant associations between variables. The results showed that interpersonal communication was significantly associated with awareness, motivation, intention, and preventive practices related to stunting prevention. However, no significant relationship was found between interpersonal communication and sociocultural factors (p = 0.629). These findings indicate that effective interpersonal communication plays a crucial role in shaping preventive behaviors, even when sociocultural influences remain unchanged. Strengthening communication competencies among health workers and Posyandu (community health post) cadres, as well as implementing family-based counseling programs, is therefore essential. Future studies are recommended to expand the research area, increase the number of respondents, and apply longitudinal approaches to better understand the long-term effects of communication-based stunting prevention interventions.

Abstract

— Improving the quality of academic services is a crucial indicator of educational quality assurance in vocational high schools. This study aims to examine the effects of the Academic Information System, Human Resource Competence, and Technology Support on Academic Service Quality, with Academic Process Effectiveness serving as an intervening variable. This research employed a quantitative approach using the Structural Equation Modeling–Partial Least Squares (SEM-PLS) method. Data were collected through a Likert-scale questionnaire administered to 50 respondents at SMK Negeri 4 Penajam Paser Utara. Data analysis was conducted using SmartPLS 4 software. The results of the measurement model (outer model) evaluation indicate that all constructs meet the criteria for validity and reliability, as evidenced by Cronbach’s Alpha, Composite Reliability, and Average Variance Extracted (AVE) values exceeding the recommended thresholds. Furthermore, the structural model (inner model) evaluation reveals that Academic Process Effectiveness and Academic Service Quality demonstrate moderate explanatory power. The direct effect analysis shows that the Academic Information System and Technology Support have a significant effect on Academic Process Effectiveness, while Academic Process Effectiveness has a significant effect on Academic Service Quality. The mediation analysis indicates that Academic Process Effectiveness significantly mediates the relationship between the Academic Information System and Academic Service Quality. However, the mediating effects of Academic Process Effectiveness on the relationships between Human Resource Competence and Technology Support with Academic Service Quality are not statistically significant. These findings highlight the importance of optimizing academic information systems supported by effective academic processes to enhance the quality of academic services in vocational high schools.

Abstract

Pangandaran Regency, located on the southern coast of Java, is highly exposed to earthquake and tsunami hazards. This vulnerability is intensified by low-lying coastal landforms, dense coastal development, and tourism activities that increase population exposure and complicate evacuation. In this context, disaster preparedness should not be understood solely as the availability of evacuation infrastructure, but as a socially and institutionally constructed capacity. This study examines disaster preparedness in Pangandaran by focusing on collaborative leadership and stakeholder communication in local disaster governance. A qualitative case study design was employed from May to August 2025. Data were collected through semi-structured interviews with three key informants representing formal institutions, volunteer groups, and the local community, supported by limited field observation. The data were analyzed thematically. The findings indicate that preparedness in Pangandaran is shaped by four interrelated dimensions: coordinative, communicative, structural-operational, and social-learning preparedness. Preparedness has been strengthened through cross-actor coordination, information verification, evacuation shelters and routes, and simulation-based learning. However, important limitations remain. Coordination still tends to center on formal actors, risk communication must operate in a dense tourism setting with diverse audiences, evacuation infrastructure is constrained by uneven access, limited visibility, and shelter capacity, and preparedness is not equally distributed across residents, newcomers, and visitors. Conceptually, this study argues that collaborative leadership in local disaster settings is not merely the presence of multiple actors, but a functional yet unequal arrangement shaped by trusted communication, role integration, and the translation of risk knowledge into collective action.

Abstract

Indonesia recorded 2,560 search and rescue (SAR) incidents in 2024, underscoring the need for leaders who can make rapid yet safety centered decisions in hazardous environments. This study examines leadership in critical decision making during high risk SAR operations through a qualitative case study of a man overboard incident handled by the Ambon Search and Rescue Office. Data were collected through in depth interviews with key informants, field observation, and review of operational documents, then analyzed using iterative reduction, descriptive synthesis, and triangulation. The decision chronology shows that operational authority was concentrated at the field commander (Dantim), with coordination intended to supply situational input before actions were authorized. However, decision quality was constrained by gaps in information synchronization across teams and command levels, particularly regarding dive planning, reporting, and validation of high risk actions. Operational stressors, including time pressure, extreme sea conditions, limited resources, external demands from family and media, and emotional strain after a teammate loss, influenced risk appraisal and could narrow attention toward mission urgency. Post operation evaluation indicated fatigue and equipment malfunction as proximate contributors to the rescuer’s fatal incident, alongside weaknesses in briefing and debriefing discipline. Strengthening rescuer safety requires clearer communication pathways for critical decisions, structured briefings and debriefings, fatigue management, equipment reliability controls, and stress informed decision training within a clear command accountability structure.

Abstract

This study aims to explore how auditors assess tax risk in ESG-based mining companies and to identify the challenges faced in the tax audit process. The study also examines strategies that auditors can implement to ensure tax compliance, as well as their role in assisting companies in formulating tax policies that support sustainability. A qualitative case study approach to explore how auditors assess and manage tax risk in ESG-based mining companies using thematic analysis. The study focuses on an in-depth analysis of tax audit practices and sustainability regulations applied within the company. Indicated that many employees still lack a deep understanding of PSAK and the taxation system, particularly carbon-related taxation. This lack of understanding creates obstacles that reduce work effectiveness and results that do not meet expectations. Another finding shows that ESG reporting systems and implementation remain weak due to the absence of comprehensive application, indicating the need for socialization programs and seminars. This findings highlight the importance of a strong foundational understanding of PSAK, especially within the mineral and mining sectors, to ensure proper and accurate application. In addition, a deep understanding of taxation is essential. In the ESG context, several interview findings indicate that reporting is not yet sufficiently detailed due to a limited understanding of the importance of ESG. This study contributes to greater openness in the academic field by emphasizing the need for new and broader knowledge in accounting that supports sustainable company growth. Continuous growth enables companies to remain profitable and enhance firm value.

Abstract

This study analyzed the factors influencing rice productivity in five area-based paddy farming development locations in Kutai Kartanegara Regency. It highlighted the importance of agricultural machinery, irrigation, high-quality seeds, farming techniques, technical support, environmental factors, and effective harvest and post-harvest management. Statistical analysis revealed that most factors, with the exception of agricultural machinery, positively impacted yields. Productivity was constrained by significant challenges, including labor shortages due to workforce migration, water scarcity during dry periods, and reliance on second-generation hybrid seeds, which limited potential output. In addition, low soil pH and inconsistent harvesting practices contributed to pest and disease outbreaks, further diminishing yields. While farmers generally demonstrated sufficient farming skills, technical guidance remained crucial for improving productivity and morale. Addressing these issues required prioritizing improvements in irrigation systems, the adoption of superior seed varieties, soil quality enhancement through targeted fertilization, and integrated strategies to resolve labor shortages. These efforts were essential for achieving sustainable rice production and strengthening agricultural resilience in the region.

Abstract

Indian mackerel (Rastrelliger kanagurta) is highly susceptible to histamine accumulation under tropical ambient storage due to histamine-forming bacteria (HFB). This study evaluated the temporal profile of HFB growth and its correlation with histamine levels in mackerel treated with Piper betle leaf extract and rice washing water. A completely randomized design with five treatments was applied: negative control, positive control, and combinations of Piper betle extract with rice washing water at ratios of 1:1, 1:3, and 1:5 (v/v). HFB populations were enumerated at 0, 6, 12, 18, and 24 hours using Niven's agar, while histamine concentrations were quantified spectrofluorometrically at 0 and 12 hours. Results showed that the 1:3 ratio treatment produced the lowest histamine level (61.11 mg/100g), suggesting enzymatic inhibition rather than merely bactericidal action. A bell-shaped dose-response relationship was observed, indicating pro-oxidant effects at excessive concentrations. The positive control exceeded the SNI limit of 100 mg/kg. This study concludes that the 1:3 combination of Piper betle extract and rice washing water has potential as a low-cost natural preservative for small-scale fisheries in tropical regions.

Abstract

The rapid advancement of digital technology has transformed various sectors, including health higher education institutions, which are now required to produce human resources who are adaptive, competent, and prepared to face the demands of the digital health industry. The COVID-19 pandemic accelerated this transformation, promoting the adoption of technologies such as e-learning, telemedicine, and artificial intelligence in both education and healthcare service delivery. This study aims to systematically review recent literature on the strategic role of health higher education institutions in shaping students' digital competencies. A literature review method was applied, analyzing 24 national and international peer-reviewed articles published between 2019 and 2025 that address the digitalization of health education and human resource development. Findings indicate that digitalization not only enhances learning access and effectiveness but also opens opportunities for interdisciplinary collaboration, improves digital literacy, and supports the development of technology-based curricula. However, several challenges persist, including digital inequality, limited infrastructure, lack of faculty training, and data privacy concerns. Therefore, a strategic and collaborative approach involving educational institutions, technology providers, and healthcare stakeholders is essential to ensure that digital integration effectively prepares graduates who are relevant, adaptive, and globally competitive.
