Abstract

Cirebon Regency is experiencing rapid development, which has led to significant changes in land use. Improperly managed land-use changes have resulted in a reduction of water catchment areas, decreasing the soil’s capacity to absorb rainfall and increasing the potential for flooding. Along with the expansion of residential areas and the growing intensity of human activities, river management problems—such as flooding and erosion—have become more frequent. Therefore, an effective river management system is needed to minimize these negative impacts. The purpose of this study is to evaluate the flood potential of the Soka River in Kedungsana Village, Cirebon Regency, using HEC-RAS hydraulic modeling. This analysis was conducted using annual maximum rainfall data from several rain stations, discharge calculations, and flood plan simulations based on the Nakayasu method and HEC-RAS modeling. The results show that parts of the Soka River’s cross-section are unable to accommodate flow discharge during the planned flood recurrence period, which may lead to overflow. It is hoped that this research will serve as the basis for recommendations to mitigate flooding in the study area.

Abstract

The construction industry has a high level of occupational accident risk, making the implementation of an Occupational Safety and Health Management System (OSHMS) essential in construction projects. This study aims to evaluate the implementation of OSHMS in the construction project of the Pamulang University Campus Building and to identify potential hazards, risk levels, and risk control measures applied on site. This research employed a quantitative descriptive method, collecting data through field observations, interviews, and questionnaires distributed to 55 respondents directly involved in the project. Data analysis was conducted using SPSS to test the validity and reliability of the questionnaire, while the HIRARC method was used for hazard identification, risk assessment, and risk control. The results indicate that all questionnaire items were valid and reliable, with Cronbach’s Alpha values of 0.842 for the likelihood variable and 0.818 for the severity variable. The evaluation of OSHMS implementation achieved an average score of 4.07, categorized as good. The highest risk was identified in upper structural work, particularly the hazard of falling from height. It can be concluded that the implementation of OSHMS in the project has been carried out effectively; however, improvements in supervision and worker compliance are still required to further reduce occupational accident risks

Abstract

In recent years, the increasing tendency of professional workers, particularly Generation Z, to change jobs has raised concerns regarding organizational commitment. This study aims to examine the effects of mental toughness and employee experience on organizational commitment, with psychological well-being and work engagement as mediating variables, among employees at the Toka Tindung Gold Mine Project in North Sulawesi, Indonesia. This research employs a quantitative approach using a cross-sectional survey design. Data were collected through structured questionnaires distributed to 118 employees and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The results reveal that mental toughness is the most significant predictor of organizational commitment, demonstrating strong direct effects on psychological well-being, work engagement, and organizational commitment. In contrast, employee experience shows a significant effect only on work engagement but does not directly influence organizational commitment. Furthermore, psychological well-being and work engagement are not found to mediate the relationship between mental toughness or employee experience and organizational commitment. These findings highlight the dominant role of personal resilience over organizational factors in shaping employee commitment, particularly within high-risk industries such as mining. The study provides both theoretical and practical contributions by emphasizing the importance of strengthening employees’ mental toughness to enhance organizational commitment and suggesting that organizations should integrate psychological resilience development into human resource strategies.

Abstract

Background: Arrhythmia is a frequent acute complication in patients with Acute Coronary Syndrome (ACS) and significantly contributes to morbidity and mortality. Myocardial ischemia, autonomic imbalance, and structural myocardial injury lead to electrical instability that may trigger supraventricular and ventricular arrhythmias. Local data evaluating the relationship between arrhythmia incidence and coronary lesion location remain limited and are essential for improving risk stratification, monitoring, and therapeutic strategies. Objective: To evaluate the burden of arrhythmia incidence in ACS patients and examine its correlation with coronary vessel involvement at Dr. Ramelan Naval Hospital, Surabaya. Methods: A prospective clinical study was conducted on 150 ACS patients treated between January and July 2024. Patients were categorized according to diagnosis (NSTEMI or STEMI), gender, age group (<60 years and ?60 years), and coronary lesion location (anterior, lateral, inferior) based on ECG and coronary catheterization findings. Arrhythmia incidence was analyzed using descriptive frequency distribution across subgroups. Results: Most patients were male (72%) and younger than 60 years (57%). Among 113 NSTEMI patients, 63 (42%) developed arrhythmias, predominantly right bundle branch block (RBBB), atrial fibrillation, and sinus bradycardia. In 37 STEMI patients, 26 (18%) experienced arrhythmias, mainly ventricular tachycardia (VT) and sinus bradycardia. Arrhythmias were more frequent in men. Inferior coronary lesions were associated with the highest arrhythmia rate (34%), compared to anterior (19%) and lateral (7%) lesions. Conclusion: Arrhythmias are common in ACS, particularly NSTEMI and inferior infarction. Age, gender, and lesion location are key predictors for determining intensive monitoring and optimal management strategies.

Abstract

This study examines the effects of psychological safety, collectivism, and power distance on innovation performance, with organizational commitment and performance management context posited as mediators, at XYZ School. The sample comprised 47 employees (teachers and staff). Data were collected via questionnaires and tested using path analysis. The results indicate that collectivism has a positive and significant effect on organizational commitment (? = 0.665; t = 4.629; p = 0.000), thus supporting H2. Collectivism also significantly and positively affects performance management context (? = 0.533; t = 2.937; p = 0.003), supporting H5. Regarding the final outcomes, organizational commitment does not significantly influence innovation performance (? = 0.051; t = 0.244; p = 0.807) — H7 rejected — whereas performance management context has a significant positive effect on innovation performance (? = 0.473; t = 2.113; p = 0.035) H8 accepted. In sum, a collectivist organizational culture strengthens organizational commitment and fosters a supportive performance management context, and it is the latter (performance management context) that significantly drives innovation performance. Psychological safety and power distance did not show direct significant impacts in this sample. The findings imply that school management should prioritize strengthening collective values and improving performance management practices to stimulate innovation

Abstract

Good Drug Distribution Practices (CDOB) is a drug distribution method that aims to ensure quality in the distribution process according to the requirements and intended use. Pharmaceutical Wholesalers (PBF) must ensure that the quality and efficacy of products during distribution are in accordance with applicable laws and regulations including Cold Chain Products (CCP) or cold chain products, namely vaccines, biological products, oncology treatments, several types of insulin and other medicines. Pharmaceutical Wholesalers (PBF) play an important role in handling and distributing preparations, including preparations that are sensitive to environmental conditions such as CCP products. This study aims to evaluate the implementation of CDOB in handling CCP products at one of the Pharmaceutical Wholesalers (PBF X) located in Manado City using the BPOM RI self-inspection checklist. The study was conducted in July 2025 with an observational method that is descriptive and evaluative. The results of the study indicate that PBF X has fulfilled all aspects of cold chain product handling related to receipt, storage, and distribution. It can be concluded that PBF X has implemented CDOB aspects in accordance with applicable regulations

Abstract

The school setting plays a key role in shaping students' character and leadership through scouting activities; however, internal dynamics can lead to conflicts that may escalate into crises, making effective conflict management and communication essential for maintaining organizational reputation. This study examines the internal issues and communication tactics of the scouting organization at State Junior High School 3 Losari, and explores how these factors shape the organization's image. A qualitative descriptive approach was employed, with data gathered through in-depth interviews, observation, and document analysis, then analyzed using Coombs' Situational Crisis Communication Theory (SCCT). The findings reveal that unequal distribution of responsibilities, communication breakdowns, and differing perspectives are the primary sources of internal conflict, which are addressed through crisis communication mechanisms including denial, consequence mitigation, relationship building, and problem-solving collectively helping to restore trust, unity, and organizational reputation. While the study underscores the importance of clear communication in scouting organizations, its limitations in scope and potential subjectivity suggest the need for future research with broader focus and more diverse methods.
