Abstract

The study explores anomaly detection in blockchain transactions within the Open Metaverse, utilizing Isolation Forest and Autoencoder Neural Networks. With the rise of the Metaverse, blockchain technology has become essential for secure digital transactions. However, the decentralized nature of blockchain makes it vulnerable to various anomalies, potentially undermining trust and security in digital spaces. Isolation Forest, an unsupervised machine learning algorithm, isolates anomalies based on the assumption that anomalies are few and distinct from regular data points. Its effectiveness in handling high-dimensional data makes it suitable for real-time applications. On the other hand, Autoencoders, a type of neural network, excel in detecting anomalies through reconstruction error, identifying data points that deviate from normal patterns. The research applied these models to a simulated dataset from the Open Metaverse, including features like transaction amount, login frequency, and session duration, to capture nuanced user behaviors. Preprocessing steps, such as one-hot encoding for categorical features and standardization for numerical features, ensured data consistency for accurate modeling. The Isolation Forest achieved a precision of 0.85, while the Autoencoder slightly outperformed it with a precision of 0.87. Both models demonstrated strong AUC-ROC values, with the Autoencoder scoring 0.85 compared to Isolation Forest’s 0.82, indicating robust performance in distinguishing normal from anomalous transactions. The findings underscore the potential of both models to enhance security in blockchain-based virtual environments, with the Autoencoder showing an edge in handling complex data patterns. However, the use of simulated data presents limitations, suggesting the need for further testing with real-world Metaverse transaction data. Future research could explore integrating other advanced algorithms, such as Graph Neural Networks, to improve anomaly detection in blockchain systems.

Abstract

The results of the study found that the government internal supervisory performance was not yet optimal in supporting the achievement of the vision and mission as well as organizational goals. This study aims to provide an overview of human capital management practices of government internal supervisory at the Ministry of Defense by using a balanced scorecard perspective approach from a stakeholder perspective, a business internal process perspective, a learning and growth perspective and a financial perspective. This study used a qualitative method with a case study approach and used purposive and snowball sampling. There are 19 informants including a structural officer, the auditor, and personnel from the National Financial and Development Supervisory Board. It is noted that the quality of the auditors does not fulfill the required quality. The recommendations include the importance of improving aspects of human resource competence through education and training for certification of the Functional Auditor (JFA) according to the level of the position, improving the quality of the code of ethics, improving the recruitment system, and increasing the budget for providing the operational budget and enhancing the quality of the government internal supervisory.

Abstract

This study aims to determine the direct effect of interpersonal communication, universal-diverse orientation (UDO), and self-efficacy on the quality of administrative services, as well as to determine the indirect effect of interpersonal communication and universal-diverse orientation (UDO) through self-efficacy on the quality of administrative services at State University of Jakarta. The research used was a survey with a causal design. The number of sample respondents was determined as 178 employees, the sampling technique was carried out by simple random (sample random sampling) from 230 employees of the State University of Jakarta. The results of this study indicate that; (1). There is a positive direct effect of Interpersonal Communication on the Quality of Academic Services, (2). There is a positive direct influence Universal-Diverse Orientation (UDO) on the Quality of Academic Services, (3). There is a positive direct effect of Self Efficacy on Academic Service Quality., (4) There is a positive direct influence of Interpersonal Communication on Self Efficacy, (5) There is a positive direct influence of Universal-Diverse Orientation (UDO) on Self Efficacy. The novelty in this research is that research conducted at this time is research looking at several variations of variables such as the influence of interpersonal communication, universal-diverse orientation (UDO), and self-efficacy on the quality of administrative services and quality variables as independent variables.

Abstract

The purpose of this study was to ascertain the direct positive effect of transformational leadership, emotional intelligence, organizational climate, and teamwork on the organizational citizenship behavior of civil servants at the Central Sulawesi Province Education and Culture Office. The novelty of this research is that no prior study has examined the effect of transformational leadership, emotional intelligence, organizational climate, and teamwork on the organizational citizenship behavior of Civil Servants at the Education and Culture Office of Central Sulawesi Province, both methodologically and practically. This research employs a survey method and falls under the category of quantitative research. The population of this study was 433 individuals, and the sample size was 100 individuals drawn using a random sampling technique. Interviews, questionnaires, and documentation studies were used to collect data. The findings of this study are as follows: (1) transformational leadership (X1) and organizational climate (X3) have a direct positive effect on organizational citizenship behavior (Y); (2) emotional intelligence (X2) and organizational climate (X3) have a direct positive effect on teamwork (X4); (3) emotional intelligence and teamwork have no direct positive effect on organizational citizenship behavior; and (2) transformational leadership does not have a direct positive effect on organizational citizenship behavior.
