Work fatigue is one of the occupational health problems that may affect productivity, concentration, and increase the risk of workplace accidents. Security officers at Ferry Mulia Raja Napitupulu Port, Balige, are at high risk of experiencing fatigue due to shift work systems, physical and mental workload, and poor sleep quality. This study aims to identify factors associated with work fatigue among security officers. A quantitative method with a cross-sectional design was applied. The sample consisted of 45 security officers selected using total sampling technique. Data were collected through questionnaires on individual characteristics, nutritional status, sleep quality, workload, and environmental temperature, and analyzed using bivariate tests. The results revealed significant relationships between age, nutritional status, sleep quality, workload, and temperature with work fatigue levels (p<0.05). It can be concluded that both individual and work environment factors contribute to fatigue among security officers. The study recommends that port management pay more attention to shift arrangements, rest patterns, and occupational health interventions to reduce fatigue risk and enhance officers’ productivity.

Stunting remains a major nutritional problem in Indonesia, impacting the quality of human resources. One important factor contributing to stunting is child feeding practices, especially during the First 1,000 Days of Life. Objective: This study aims to analyze the relationship between child feeding practices and stunting in toddlers. Method: This study used a cross-sectional design conducted in the Oesao Community Health Center (Puskesmas Oesao) working area. The sample was 30 toddlers aged 6–59 months selected using a purposive sampling technique. Child feeding practices were measured using a structured questionnaire, while stunting status was determined based on the WHO standard length/height-for-age (PB/U or TB/U) index. Data analysis was performed univariately and bivariately using the Chi-Square test. Results: The results showed that most toddlers with inadequate feeding practices experienced stunting. Bivariate analysis showed a significant relationship between child feeding practices and stunting (p < 0.05). Conclusion: Child feeding practices are significantly associated with stunting in toddlers. It is necessary to increase nutritional education and support families in feeding children as an effort to prevent stunting.

Hemangioma is the most common benign vascular tumor in infancy and is generally characterized by a proliferative phase followed by spontaneous involution. Although most cases resolve without intervention, treatment is required when hemangiomas cause functional impairment, ulceration, or life-threatening complications. Lingual hemangioma is a rare presentation and may result in significant feeding difficulties and airway compromise, requiring prompt and multidisciplinary management. This study aims to report the comprehensive management of a refractory lingual hemangioma in an infant, emphasizing diagnostic evaluation, therapeutic strategy, and nutritional support. A six-month-old female infant presented with a lingual hemangioma associated with progressive feeding difficulties. Prior to initiating therapy, a thorough diagnostic workup was performed, including echocardiography to assess cardiac function, magnetic resonance imaging (MRI) to evaluate lesion extent, and computed tomography angiography (CT-angiography) to delineate vascular anatomy. The patient initially received oral propranolol as first-line therapy; however, due to an inadequate response, combination chemotherapy with Bleomycin–Vincristine (BV) was initiated. To minimize the risk of toxicity, a 50% dose reduction was applied. Clinical evaluation demonstrated a favorable therapeutic response, with a reduction in lesion size and improvement in feeding ability after 10 weeks of treatment. No severe adverse effects were observed during the treatment period. To ensure adequate nutritional intake and support growth, enteral nutrition via a nasogastric tube (NGT) was provided throughout the course of therapy. This case highlights the importance of comprehensive diagnostic assessment, individualized treatment planning, and close monitoring in refractory hemangioma. In addition, optimal nutritional support plays a crucial role in overall patient outcomes. A multidisciplinary approach is essential for the successful management of complex infantile hemangiomas with functional complications.

Mining companies are increasingly required to demonstrate environmental, social, and governance (ESG) accountability through sustainability reporting (SR). However, empirical evidence regarding the impact of SR on firm value in Indonesia’s mining sector remains inconsistent. This study aims to systematically examine the relationship between sustainability reporting and firm value using legitimacy theory as the conceptual framework. A Systematic Literature Review was conducted following the PRISMA 2020 protocol, employing narrative and thematic synthesis. Peer-reviewed articles published between 2018 and 2025 were retrieved from Google Scholar, Garuda Portal, and SINTA databases using relevant keywords. From 4,260 initial records, 11 studies met the inclusion criteria after screening, deduplication, and quality appraisal using an adapted CASP checklist. The findings reveal three dominant patterns: most studies report a positive effect of SR on firm value through improved transparency, corporate reputation, and investor confidence; several studies find no significant relationship due to short-term investor orientation; while a minority report negative effects associated with low disclosure quality and greenwashing concerns. Furthermore, the effectiveness of SR is influenced by disclosure quality, corporate governance, profitability, and leverage. This study implies that sustainability reporting can enhance firm value when disclosures are credible, consistent, and material, supporting legitimacy theory and encouraging alignment with the GRI 14: Mining Sector 2024 standard.

This study aims to analyze the differences in motorcycle traffic flow (Q) during the morning and afternoon peak hours as an indicator of roadway operational performance, referring to the Indonesian Road Capacity Guidelines (PKJI) 2014, with a case study on Mawar Street–Wijaya Kusuma Street, Jember Regency. The research data were obtained from 12 observation points through traffic surveys that recorded motorcycle traffic flow in vehicles per hour (veh/h). The analytical methods used include descriptive statistical analysis, normality testing, and paired sample t-test. The results show that the average motorcycle traffic flow during the morning peak hour is 115.58 veh/h with a standard deviation of 62.97, while during the afternoon peak hour it is 63.25 veh/h with a standard deviation of 28.57. The paired sample t-test yields a significance value of 0.015 (p < 0.05), indicating a statistically significant difference between morning and afternoon traffic flows. These findings suggest that the level of roadway capacity utilization is higher during the morning peak hour, which is closely associated with dominant routine travel activities such as commuting to work and school. The results of this study are expected to serve as a basis for evaluating roadway operational performance and to support traffic management and traffic engineering planning aimed at improving road network performance and reducing congestion.

Koperatives are a form of people-based economic organization that play a strategic role in improving community welfare and strengthening the national economy. However, many cooperatives still face organizational and managerial challenges that limit their economic performance. This study aims to analyze the relationship between cooperative organizational structures, governance mechanisms, and the economic performance of cooperatives in the context of modern economic transformation. A qualitative descriptive approach was employed to gain an in-depth understanding of organizational practices within cooperatives. Data were collected through in-depth interviews, participatory observation, and document analysis involving cooperative managers, members, and supervisors selected purposively. The findings indicate that cooperatives with clear organizational structures, professional management, transparent governance, and active member participation tend to demonstrate better economic performance and sustainability. Conversely, weak organizational arrangements and low member involvement are associated with stagnation in cooperative economic activities. These results highlight that organizational quality is a key determinant of cooperative success, not merely financial factors. The study implies that strengthening cooperative governance, improving human resource capacity, and enhancing member participation are essential strategies to increase the competitiveness of cooperatives in the digital economy era. This research contributes to the development of cooperative economic theory and provides practical recommendations for cooperative managers and policymakers.

This study analyzes the corporate crime perspective and directors’ liability in the LNG procurement case at Pertamina as a State-Owned Enterprise (SOE). The research aims to examine how the elements of corporate crime are constructed, how directors’ actions are assessed within the framework of fiduciary duty and the business judgment rule, and what legal implications arise for corporate accountability in SOEs. The study employs a normative juridical method using a case approach, statute approach, and conceptual approach. Primary data consist of court documents, statutes, and regulatory frameworks, while secondary data are obtained from academic journals, institutional reports, and credible publications. The findings reveal that distinguishing legitimate business risk from abuse of authority is central to determining corporate criminal liability, particularly when decisions intersect with state finances and public interests. The analysis further indicates that SOE directors carry dual obligations: to ensure effective corporate governance while at the same time facing heightened exposure to criminal liability when losses are associated with state assets. This study contributes by clarifying how legal assessments should balance accountability with the protection of reasonable managerial discretion. The implications highlight the need for clearer decision-making standards, stronger governance mechanisms, and better alignment between corporate law and anti-corruption frameworks in order to promote legal certainty without discouraging prudent business judgment.

Postoperative pain is a common clinical condition experienced by patients after surgical procedures and may hinder the recovery process if not properly managed. In addition to pharmacological therapy, safe and effective non-pharmacological interventions are needed, one of which is early mobilization. This study aimed to analyze the effect of early mobilization on pain reduction in postoperative surgical patients. A scoping review method was conducted based on the Arksey and O’Malley framework. Literature searches were performed using ScienceDirect, PubMed, and Google Scholar databases with a PICO strategy, including articles published within the last five years. From a total of 167,948 identified articles, 10 studies met the inclusion criteria and were included in the analysis. The results showed that early mobilization performed gradually and according to patients’ clinical conditions had a significant effect on reducing postoperative pain intensity. In addition, early mobilization was associated with improved comfort, enhanced functional recovery, and faster postoperative rehabilitation without increasing the risk of complications. Although variations were found in the timing and type of mobilization across studies, overall evidence supports that early mobilization is safe and effective. In conclusion, early mobilization can be recommended as an evidence-based nursing intervention for postoperative pain management.

One of the most common occupational health risk factors found in industrial areas is noise, and long-term exposure ≥85 dB(A) for more than 8 hours has the potential to cause progressive and permanent Noise-Induced Hearing Loss (NIHL). The risk of NIHL increases if workers do not use Ear Protection Equipment (APT) optimally and have certain individual factors such as age, working period, and length of exposure. This study aims to determine the relationship between the use of APT and worker factors with hearing loss due to noise in PT HMK II Palembang City in 2025. This study uses an analytical quantitative design with a cross sectional approach. A sample of 55 respondents was selected through purposive sampling technique. Data was collected using a questionnaire and analyzed by chi-square test. The results showed that there was a significant relationship between the use of APT (p=0.000) and there was no significant relationship between, the age of workers (p=0.838), working time (p=0.290), and length of work (p=0.172) and noise-induced hearing loss. The use of APT has been shown to be associated with a reduced risk of noise-induced hearing loss, although age, length of employment, and length of work did not show a significant relationship.

Choking is a dangerous thing for children, especially children with special needs who require proper handling, and parents as the closest people to the child must have first aid skills for choking. The purpose of this study is to determine the effect of ANSIVI (Animation and Simulation Video) Choking Management on parents' ability in first aid for choking. The research design was a pre-experimental design with a one-group pretest-posttest approach without control. The purposive sampling technique obtained 36 respondents. The research instrument used an observation sheet for first aid for choking. The statistical test was the Wilcoxon Signed Rank Test with α 0.05. The results of the study before being given the ANSIVI (Animation and Simulation Video) Choking Management intervention showed that all (100%) respondents had insufficient ability, and after the intervention the majority (52.8%) of respondents had sufficient ability. The results of the statistical analysis obtained a p-value of 0.013 < α 0.05, so there is an effect of ANSIVI (Animation and Simulation Video) choking management on parents' ability in first aid for choking. The ANSIVI method (Video Animation and Simulation) combines two methods so that it is more interesting, interactive, and effective because the video is captured by the eyes and ears and then will be detected and converted into signals to the optic nerve and auditory nerve and forwarded to the brain, program area, and frontal area to be associated so that it will affect the respondent's ability. The ANSIVI method can be used in education for all parents and school residents as a first aid effort for choking, especially for children with special needs.

This study aims to examine the role of work engagement in life satisfaction among volunteers of the Involuntir community. Engagement in volunteer activities is often associated with subjective well-being; however, the dynamics of this relationship have not been fully understood, particularly in the context of young volunteers. This study employed a quantitative method with purposive sampling, involving 122 active Involuntir volunteers. The instruments used were the Utrecht Work engagement Scale (UWES-17) to measure work engagement and the Satisfaction With Life Scale (SWLS) to assess life satisfaction. Data analysis was conducted using Spearman’s rho correlation test and regression analysis due to non-normally distributed data. Descriptive analysis results indicated that volunteers’ work engagement levels were categorized as high, while life satisfaction levels were categorized as moderate. The results of the Spearman’s rho correlation test revealed a significant negative relationship between work engagement and life satisfaction (r = −0.522; p < 0.05). Furthermore, regression analysis showed that work engagement had a significant effect on life satisfaction with a negative coefficient direction (β = −0.072; p < 0.05), indicating that higher levels of work engagement were associated with lower levels of perceived life satisfaction. Additionally, the Mann–Whitney difference test results indicated no significant differences in either work engagement or life satisfaction based on gender. Overall, this study suggests that high levels of volunteer engagement need to be managed in a balanced manner, as excessive engagement may potentially reduce life satisfaction. These findings highlight the importance of sustainable volunteer engagement management in supporting the subjective well-being of young volunteers

Sleep is a fundamental biological need for adolescents and plays a crucial role in supporting cognitive function, emotional regulation, and overall mental health. Despite its importance, sleep quality among adolescents has increasingly declined due to the interaction of individual characteristics, social environments, and daily sleep behaviors. This article aims to analyze the factors influencing adolescent sleep quality using the Social Cognitive Theory framework through a literature review of national and international journals published between 2021 and 2025. The findings show that adolescent sleep quality is shaped by personal factors, including attitudes toward sleep, self-efficacy, and psychological conditions. Environmental factors, such as parental support, peer influence, and academic demands, also significantly affect sleep patterns. In addition, behavioral factors, particularly sleep hygiene practices, play a key role in determining sleep quality. Consistently, unhealthy sleep behaviors are associated with poor sleep quality. Therefore, comprehensive interventions are needed, involving the improvement of sleep habits, strengthening adolescents’ self-regulation abilities, and enhancing family and school support to promote better sleep quality.

Drug abuse is a serious global public health problem, with the prevalence in Indonesia reaching 1.73% or about 3.33 million people in 2023, mainly among those aged 15–24 years. Understanding the psychological determinants of this behavior is crucial to enhance prevention and rehabilitation efforts. Objective: To analyze determinants of drug abuse behavior based on the Health Belief Model (HBM) through a literature review of studies published between 2015 and 2025. Methods: A literature review of 8 academic articles from Google Scholar and PubMed, limited to open‑access Indonesian- and English‑language journals examining HBM constructs related to drug abuse and rehabilitation participation. Results: HBM variables were generally associated with drug abuse behavior and rehabilitation adherence, with self‑efficacy emerging as the most consistent determinant, followed by perceived susceptibility and perceived severity. Perceived barriers, especially complex administrative procedures, distance, costs, and stigma, were identified as major obstacles to engaging in rehabilitation. Conclusion: The HBM is useful for mapping determinants of drug abuse behavior and highlights the need to strengthen self‑efficacy, risk perceptions, and barrier reduction within health promotion and community‑based rehabilitation programs.

Chronic kidney disease (CKD) is a global health problem with continuously increasing prevalence and mortality. This condition is characterized by a progressive and irreversible decline in kidney function, which is clinically assessed using the estimated glomerular filtration rate (eGFR) as one of the main parameters for staging and monitoring disease progression. Red blood cell distribution width (RDW) is a hematological parameter that reflects the degree of variation in erythrocyte size. In patients with CKD, elevated RDW levels are often associated with oxidative stress and chronic inflammation, which may accelerate kidney damage and increase mortality risk. To analyze the correlation between RDW and eGFR values in patients with chronic kidney disease at ODSK Hospital, North Sulawesi Province. This study used an analytical observational design with a cross‑sectional approach. It was conducted retrospectively using secondary data from the medical records of CKD patients at ODSK Hospital, North Sulawesi Province, from February 2024 to August 2025. This study used a total sampling method with 189 CKD patients who met the inclusion and exclusion criteria.  Based on Spearman-rank correlation analysis, the p‑value obtained was 0.129 (>0.05). There was no significant relationship between RDW and eGFR values in CKD patients at ODSK Hospital, North Sulawesi.Province.

Production planning and inventory control are critical aspects of operations management, as they directly influence cost efficiency, resource utilization, and the continuity of the production process. Ineffective planning and inventory decisions may lead to excessive costs, production delays, or imbalances between supply and demand. The complexity of these problems, which often involve multi-period horizons and multi-stage decision-making processes, has encouraged the application of quantitative optimization methods, one of which is dynamic programming. This study aims to analyze and synthesize the application of dynamic programming in production planning and inventory control through a Systematic Literature Review (SLR) approach. The SLR process was conducted by systematically identifying, selecting, and analyzing 15 relevant national journal articles published between 2015 and 2024 and obtained from various recognized scientific databases. The reviewed literature indicates that dynamic programming is effective in supporting optimal decision-making by determining appropriate production quantities and inventory levels, minimizing total production and holding costs, and managing fluctuating demand conditions. In addition, this method helps reduce the risks associated with overstock and stockouts by considering sequential decision structures. However, the findings also reveal several limitations of dynamic programming, including high computational complexity, strong dependence on deterministic data assumptions, and limited flexibility in handling high levels of uncertainty. These constraints suggest the need for further methodological development or integration with other approaches to enhance practical applicability.

The increasing integration of Cyber physical Systems (CPS) into industrial environments has highlighted the need for secure, scalable, and efficient cryptographic key management systems. Traditional centralized key management protocols are often limited by vulnerabilities such as single points of failure, scalability issues, and significant overhead. Blockchain technology presents a promising solution to these challenges by leveraging decentralization, immutability, and transparency to enhance security and efficiency in CPS. This study investigates the use of blockchain based cryptographic key management systems, focusing on smart contracts for automated key distribution and rotation. Experimental results demonstrate that blockchain based systems significantly improve system integrity, auditability, and resilience, offering enhanced protection against cyber-attacks and reducing the risks associated with centralized systems. Blockchain’s decentralized architecture eliminates the need for a central authority, making it more resistant to tampering and operational failures. Additionally, smart contracts automate the key management process, improving efficiency while maintaining a high level of security. The study also evaluates the impact of blockchain on communication performance, finding that it reduces latency and overhead by automating processes and eliminating the need for centralized control. Despite these advantages, challenges such as scalability, latency, and integration with legacy systems remain. The study concludes by suggesting future research directions, including the development of lightweight blockchain protocols tailored for industrial applications and the integration of blockchain with emerging technologies like Artificial Intelligence (AI) to further enhance key management in CPS. Blockchain based solutions have the potential to transform the security landscape of industrial environments, offering greater robustness, reliability, and trust.

Acne (Acne vulgaris) is one of the most common skin problems, affecting 80–85% of adolescents aged 15–18 years, with some cases persisting into adulthood. One of the associated bacteria is Staphylococcus epidermidis, a normal skin flora that can become an opportunistic pathogen. Bay leaves (Syzygium polyanthum) are known to contain secondary metabolites such as alkaloids, flavonoids, tannins, saponins, and essential oils with antibacterial activity. This study aimed to formulate ethanol extract of bay leaves into ointments with concentrations of 10%, 20%, and 30%, test their antibacterial activity against Staphylococcus epidermidis using the disc diffusion method, and evaluate their physical quality (organoleptic properties, homogeneity, pH, adhesion, and spreadability). Results showed that the ethanol extract of bay leaves contained alkaloids, flavonoids, saponins, and tannins. The ointments met topical quality standards with pH 5.8–6.9, adhesion time 36–41 seconds, and spreadability 6.9–8.1 cm. Antibacterial activity increased with higher concentrations: 7.8 mm (10%), 12 mm (20%), and 15 mm (30%), although still lower than the positive control (clindamycin, 34 mm). In conclusion, ethanol extract of bay leaves has potential as an active ingredient in topical anti-acne ointments, but further studies with higher concentrations, in vivo testing, and optimized formulations are needed to achieve efficacy comparable to synthetic antibiotics.  

General practitioners play a crucial role in the delivery of healthcare services in public hospitals, where limited organizational resources and high service demands often place significant pressure on medical personnel. These conditions may disturb work–life balance, increase the risk of burnout syndrome, and ultimately lead to higher turnover intention. This study aimed to analyze the effect of work–life balance on turnover intention, with burnout syndrome acting as an intervening variable among general practitioners at RSUD Balaraja. An observational analytic design with a cross-sectional approach was applied, involving all 40 general practitioners working in the emergency department and inpatient units through a total sampling technique. Data were collected using standardized instruments, namely the Work–Life Balance Scale, Maslach Burnout Inventory, and the Intention to Quit Questionnaire. Data analysis was conducted using Spearman correlation and Structural Equation Modeling–Partial Least Squares (SEM-PLS). The results revealed a significant relationship between work–life balance and burnout syndrome, as well as between work–life balance and turnover intention. Burnout syndrome was also significantly associated with turnover intention. Further analysis showed that work–life balance had both direct and indirect effects on turnover intention, with burnout syndrome partially mediating this relationship. In conclusion, work–life balance and burnout syndrome are important determinants of turnover intention among general practitioners. Therefore, hospital management should prioritize strategies such as workload regulation, enhanced organizational support, and burnout prevention to retain medical staff and maintain the quality of healthcare services in public hospitals.
