s characterized by fractures, conduits, and interconnected channel networks that significantly influence groundwater flow dynamics. This literature review aims to synthesize current knowledge regarding the effects of karst on water circulation and permeability in carbonate aquifers based on hydrogeological, hydrochemical, geophysical, and numerical modeling studies from various regions worldwide. The review shows that karstification substantially enhances hydraulic conductivity and produces complex flow regimes ranging from diffuse fracture flow to turbulent conduit flow. The epikarst zone plays an important role in regulating infiltration and recharge distribution, while tectonic structures such as faults and fractures strongly control groundwater pathways and aquifer compartmentalization. Karst aquifers also exhibit strong spatial variability in permeability, making groundwater flow and contaminant transport difficult to predict using conventional hydrogeological approaches. In addition, the integration of equivalent porous medium (EPM), discrete fracture network (DFN), and conduit network (CN) models is essential for accurately representing karst aquifer behavior. Understanding the influence of karstification on groundwater circulation is therefore crucial for sustainable groundwater management and aquifer vulnerability assessment, particularly in regions facing increasing water demand and climate change pressures.
Abstract:This study aims to analyze the determinants of dividend policy and their implications for stock returns among companies listed on the Indonesia Stock Exchange (IDX) during the 2019–2024 period. Specifically, the study examines…
examines the effects of Return on Assets (ROA), Current Ratio (CR), Debt-to-Equity Ratio (DER), Sales Growth (SG), and Firm Size (SIZE) on Dividend Payout Ratio (DPR), as well as the impact of DPR on stock returns. The research employs a quantitative approach using secondary data obtained from the annual financial reports of dividend-paying companies listed on the IDX. The sample consists of 822 firm-year observations selected through purposive sampling. Data analysis was conducted using path analysis with multiple regression models, supported by classical assumption tests including normality, heteroscedasticity, multicollinearity, and autocorrelation tests. The results indicate that during the overall period of 2019–2024, ROA, DER, and SG significantly and negatively affect DPR, while CR and SIZE do not have significant effects. Furthermore, CR negatively affects stock returns, whereas SG and DPR have positive and significant effects on stock returns. The findings also reveal that the relationships among financial performance, dividend policy, and stock returns vary across pre-crisis, crisis, and post-crisis periods. Overall, dividend policy plays an important mediating role in influencing stock returns, particularly during and after periods of financial uncertainty. These findings provide valuable insights for investors, corporate managers, and policymakers in formulating dividend and investment decisions under different economic conditions.
Abstract:The rapid advancement of digital technology has fundamentally reshaped consumer behavior globally, with social media becoming the primary channel for product information seeking. Approximately 51% of Indonesians rely on…
user reviews before purchasing, and 62% have bought products under the direct influence of Social Media Influencers (SMIs). Despite this, the psychological mechanisms linking influencer characteristics to purchase intention remain fragmented across sectors and platforms. This systematic literature review synthesizes nineteen empirical studies published between 2020 and 2025, spanning beauty, fashion, gadget, and sustainable product sectors across multiple countries, to examine how Source Credibility (attractiveness, trustworthiness, expertise) and Parasocial Interaction (PSI) jointly shape consumer purchase intentions. Three core findings emerge: (1) trustworthiness is the sole credibility dimension that is universally and consistently significant across all contexts, fundamentally challenging assumptions about the equal contribution of the three credibility dimensions; (2) PSI operates not as a single mediator but as a multi-pathway psychological bridge through hedonic value, brand attitude, vicarious experience, and social-personal value whose specific active pathway is contingent on platform, product type, and cultural context; and (3) generational and cultural moderators systematically shape which credibility dimension most powerfully drives PSI. A Proposed Integrative Conceptual Framework and a synthetic cross-study comparison matrix (Table 2) consolidate these findings. Results offer strategic implications for influencer marketing practice and identify priority directions for future research.
Abstract:Improving the quality of modern healthcare services largely depends on the effectiveness and efficiency of nursing personnel as the frontline providers of patient care. The complex and high-pressure work environment of specialized…
pecialized hospitals requires nurses to cope with emotional demands, heavy workloads, and rapid decision-making in critical situations. These conditions make emotional intelligence one of the important psychological factors influencing nursing performance quality. This study aimed to analyze the relationship between emotional intelligence and nursing work efficiency at King Fahad Specialist Hospital – Qassim Cluster, Saudi Arabia, in 2026. This study employed a quantitative approach with a cross-sectional design. The study population consisted of all active nurses working at King Fahad Specialist Hospital, Qassim Health Cluster. A total of 312 nurses were selected using stratified random sampling. Data were collected using the Emotional Intelligence Scale and Nursing Work Efficiency Scale, both of which had been tested for validity and reliability. Data analysis was conducted using Structural Equation Modeling–Partial Least Squares (SEM-PLS) with SmartPLS 4 software. The results revealed that emotional intelligence had a positive and significant effect on nursing work efficiency, with a path coefficient of 0.642, t-statistics of 9.871, and p-value < 0.001. The R-square value of 0.58 indicated that emotional intelligence explained 58% of the variance in nursing work efficiency. Emotional regulation and empathy emerged as the dominant indicators contributing to improved communication quality, clinical decision-making, and patient care effectiveness. This study concludes that emotional intelligence is an important psychological resource in improving nursing work efficiency in specialized hospitals. The findings strengthen the Job Demands–Resources (JD-R) Theory and Emotional Intelligence Theory in explaining the relationship between psychological resources and nursing performance. This study is expected to provide theoretical contributions to the development of nursing management literature and practical contributions for hospitals in designing healthcare human resource development strategies based on psychological well-being.
Abstract:Healthcare service quality is an important factor influencing patient satisfaction, particularly in pediatric nursing services in hospitals. The SERVQUAL model, which includes the dimensions of tangible, reliability, responsiveness,…
ponsiveness, assurance, and empathy, is widely used to evaluate healthcare service quality. This study aimed to analyze the relationship between service quality and pediatric patient satisfaction in the Bung Hatta Inpatient Ward of Tk III Dr. Reksodiwiryo Hospital, Padang. This study employed a quantitative approach with an analytic descriptive design and a cross-sectional method. The sample consisted of 30 respondents who were parents or guardians of pediatric patients hospitalized for at least three days. Respondents were selected using an accidental sampling technique. Data were collected using a SERVQUAL-based questionnaire with a Likert scale and analyzed using univariate and bivariate analysis with the Chi-square test at a significance level of 0.05. The results showed that the majority of respondents were satisfied with nursing services (80%). Bivariate analysis indicated significant relationships between the tangible (p=0.033), reliability (p=0.049), and assurance (p=0.040) dimensions and pediatric patient satisfaction. However, responsiveness and empathy dimensions were not statistically associated with patient satisfaction (p>0.05). In conclusion, nursing service quality is associated with pediatric patient satisfaction in several SERVQUAL dimensions, particularly tangible, reliability, and assurance. Continuous improvement in nursing service quality is necessary to enhance satisfaction among pediatric patients and their families in hospital settings.
Abstract:This study aims to analyze the effect of workload, multiple role conflict, and work stress on job satisfaction and their impact on the performance of female employees (nurses) at Permata Pamulang Hospital. The background…
of this research is based on the hospital’s unmet performance targets, high nursing workloads, the dominance of female employees, and the emergence of conflicts between work demands and family responsibilities that potentially increase stress and reduce job satisfaction. This research adopts a quantitative approach using a survey method. The population consists of all female employees (nurses) at Permata Pamulang Hospital, with a saturated sampling technique. Data were collected through questionnaires using a Likert scale and analyzed using path analysis to examine both direct and indirect relationships among variables. The results indicate that workload, multiple role conflict, and work stress have a significant effect on job satisfaction. Furthermore, job satisfaction has a significant effect on employee performance and acts as an intervening variable in the relationship between workload, multiple role conflict, and work stress on performance. These findings suggest that improving nurses’ performance can be achieved through proportional workload management, reducing multiple role conflicts, and controlling work stress to enhance job satisfaction. This study is expected to provide managerial insights for hospital management in formulating human resource policies that emphasize work-life balance and employee well- being.

Abstract:This study examines the digitalization of agriculture and its implications for food security in South Sulawesi, focusing on structural challenges, policy responses, and pathways toward sustainable self-sufficiency. Despite…
te relatively stable rice production, food security in the province remains vulnerable to climate variability, irrigation constraints, fragmented distribution systems, and uneven digital integration. Using a mixed-method approach that combines quantitative survey data and qualitative policy analysis, this research evaluates the relationship between digital adoption and farmer performance. The findings indicate that farmers utilizing digital tools demonstrate higher production stability, stronger market price awareness, and better planting planning accuracy compared to non-digital farmers. However, digital literacy gaps and limited institutional coordination constrain broader system transformation. Policy responses remain largely reactive and sectorally fragmented. The study proposes a Digital-Sustainable Self-Sufficiency Framework that integrates digital infrastructure expansion, smart irrigation governance, supply chain monitoring, and inter-agency coordination. The findings suggest that digitalization should be positioned not merely as technological adoption but as a governance transformation mechanism to strengthen adaptive capacity, enhance coordination, and achieve resilient and sustainable food security.

e availability of competent and standardized laboratory human resources (HR). Polymerase Chain Reaction (PCR) testing has become the primary diagnostic method for pathogen detection, both in routine services and in public health emergency situations. The development of a PCR training curriculum and modules by the Center for Health Biology Laboratory (BBLBK) represents a strategic step toward standardizing the competencies of laboratory personnel. This article aims to describe the urgency of implementing certified PCR training policies as part of a national system for enhancing the competence of health laboratory human resources. The writing method employs policy analysis based on document review and the framework of national health regulations. The analysis results indicate variations in laboratory personnel competencies, the absence of a national certification scheme, limited availability of trainers, and the need for continuous curriculum updating. Certified PCR training is therefore recommended as a national instrument for fulfilling competency standards in health laboratories. The integration of training into the health human resource development system, along with the strengthening of quality- and safety-based approaches, is key to the successful implementation of this policy.
