Abstract

The development of artificial intelligence (AI) in organizational decision-making has given rise to the phenomenon of cognitive offloading that has the potential to affect the quality of managerial judgment. This study aims to analyze the influence of cognitive offloading on the quality of managerial assessment by considering the role of metacognition and cognitive bias. The study used a quantitative approach with an explanatory design, involved 248 managers as respondents through a questionnaire, and was analyzed using PLS-SEM. The results showed that cognitive offloading had a negative effect on the quality of judgment, while metacognition had a positive effect and acted as a partial mediator. In addition, cognitive bias has been shown to lower the quality of decisions. These findings confirm that the use of AI is dualistic and requires balanced cognitive engagement. This research contributes to the development of management theory and practice in the more critical use of AI

Abstract

The intermittency of renewable energy, especially solar and wind power, is a major challenge in maintaining the stability of modern electric power systems, especially in the parameters of frequency, voltage, and supply continuity. This study analyzes the integration of Hydrogen Energy Storage System (HESS) in a solar–wind hybrid microgrid in the southern coastal region of West Java which has characteristics of solar radiation variability and high wind speed. The methods used include dynamic modeling based on nonlinear differential systems for electrolyser components, pressurized hydrogen storage tanks, and fuel cells, as well as stability analysis using a small-signal approach and MATLAB/Simulink-based transient simulation. The results showed that HESS integration was able to significantly reduce power fluctuations by about 40 percent and improve system frequency stability compared to systems without storage. The implementation of a control strategy based on a predictive control model has also been proven to improve the efficiency of energy distribution and system response to changes in load and energy source. Analysis of thermodynamics and fluid mechanics in hydrogen compression processes shows that storage pressures in the mid-range of 30 to 50 bar provide a balance between efficiency and system safety. The study confirms that hydrogen storage technology is an effective solution to improve the stability and flexibility of intermittent renewable energy systems, as well as support the development of sustainable energy systems in regions with high renewable energy penetration

Abstract

The discipline of Occupational Health and Safety (OHS) is undergoing a paradigm shift driven by advances in wearable technology and machine learning. Lagging indicators, such as the Total Recordable Incident Rate (TRIR), have been historically considered the most common risk management metrics for gauging the safety performance of risk managers. Such measures merely describe what occurs once one has been defeated, but not the option of preventing the initial loss. The paper endorses the proposal to change to leading indicators, controlled by predictive analytics and the Internet of the Worker (IoW). By studying real-time biometric and environmental information, organizations would be able to identify pre-incident behavior patterns and prevent losses. This paper will examine the technically based infrastructure of the IoW, validate the financial case, using the Total Cost of Risk (TCOR) analysis, and a holistic ROI model, the underwriting implications of the Experience Modification rate (EMR) optimization and Schedule Rating and the ethical remit of data governance and just culture that must accompany the implementation of these technologies, based on the frames of the Associate in Risk Management (ARM) system

Abstract

This study aims to analyze factors related to the incidence of Loss To Follow Up (LTFU) in TB patients at the Bintuni Health Center, Teluk Bintuni Regency. The study used an analytical observational design with a cross-sectional design based on secondary data recorded in the TB 03 register. The study population is all TB patients who started treatment in the period from January 2024 to August 2025, with a total of 245 patients sampled. The results showed that the relationship between age (p=0.260), sex (p=0.998), distance traveled (p=0.967), PMO (p=0.536), and ethnicity (p=0.141) was not significant with the incidence of LTFU. Meanwhile, the variables of education (p=0.000), employment (p=0.000), and drug side effects (p=0.000) were significantly related to the incidence of LTFU. Drug side effect variables are the most dominant factor in the incidence of LTFU

Abstract

Hospitals must maintain medicine availability in the right type, quantity, quality, and time. This study mapped drug supply chain risks at the Pharmacy Installation of Hospital X, Surakarta, and prioritized mitigation using SCOR and House of Risk. A descriptive design was applied to four pharmacists directly involved in planning, procurement, compounding, distribution, and return processes. The study identified 21 risk events and 21 risk agents. The main risk agents were emergency time pressure, insufficient pharmacy staff, slow bureaucracy, recurring e-catalog problems, limited SIMRS support for e-prescribing, and weak distributor communication. The priority actions were routine cross-unit coordination, escalation of service barriers to leadership, and service quality standards for monitoring

Abstract

Background: Tooth discoloration is a common aesthetic problem that can affect self-confidence. One solution to address this problem is tooth whitening, using either chemical or natural ingredients. Objective: To compare the effectiveness of red grape (Vitis vinifera L.) and green grape (Vitis vinifera) extracts on tooth discoloration during teeth whitening. Methods: This is a laboratory experimental study using a pre-test and post-test control group design. The samples used were 24 permanent first and second premolar teeth, which were soaked in red grape extract and green grape extract for 1, 3, and 5 hours. Tooth color measurements were carried out before and after immersion using a VITA Easyshade V digital spectrophotometer, based on the L (lightness), C (chroma), and H (hue) values. Results: The study showed that there was an increase in the L value and a decrease in the C and H values indicating a significant difference in tooth color (sig <0.05) in all immersion groups, both using red grape extract and green grape extract. The most significant increase in the L value occurred in the 5-hour immersion group with green grape extract juice. Conclusion: There is a difference in effectiveness between red grape extract and green grape extract in the tooth whitening process. Green grape extract is more effective as a natural external tooth whitening ingredient, especially with a longer immersion duration, because it is influenced by its active ingredients such as malic acid, vitamin C, flavonoids, and phenols, there is also a difference in pH value in both red grape extract and green grape extract. The pH value of green grape extract is lower than that of red grape extract

Abstract

Uncertainty in the price of agricultural commodities is the main challenge faced by farmers in the Indonesia-Timor Leste border area, especially in Belu Regency, East Nusa Tenggara. This study aims to analyze how corn farmers interpret market uncertainty and its implications for their livelihood strategies. This research uses a qualitative approach through in-depth interviews and field observations of small-scale farmers in the 2024 harvest season. The results show that farmers not only view uncertainty as a risk, but also as a strategically anticipated condition. Farmers' interpretations are influenced by limited access to information, dependence on collectors, and cross-border market dynamics. This condition encourages adaptive strategies such as business diversification, crop storage, and the use of informal marketing networks. This research emphasizes the importance of strengthening access to market information and price stabilization policies to increase the livelihood resilience of farmers in border areas

Abstract

This study aims to analyze the dynamics of apparatus placement and public service workload at the village level and develop the Adaptive Urban Village Staffing Model as a more adaptive approach to human resource management. The research uses a qualitative method with a case study design in three urban villages in Malang City, namely Pandanwangi, Gadang, and Kotalama. Data was collected through in-depth interviews, observations, and documentation, then analyzed using thematic analysis. The results of the study show that there is an imbalance between the number of apparatus and the service workload, which has an impact on the effectiveness of public service performance. In addition, the placement of apparatus still tends to be administrative and not based on the real needs of the organization. The developed model emphasizes the importance of sub-district categorization, adjustment of apparatus competencies, and differentiation of workload and performance allowances. This research contributes to the development of more responsive and needs-based management of public sector apparatus
