Abstract

The rapid growth of Internet of Things (IoT) and edge computing technologies has introduced new security challenges due to the distributed, heterogeneous, and dynamic nature of these environments. Conventional static security mechanisms, such as rulebased authentication and fixed trust models, are often inadequate for addressing evolving threats and abnormal behaviors in largescale IoT systems. To overcome these limitations, this study proposes a machine learningbased trust evaluation framework for enhancing security in distributed IoT environments. The proposed approach dynamically assesses the trustworthiness of IoT nodes by analyzing behavioral and interactionbased features collected at the edge layer. Machine learning models are trained to classify nodes into trusted and malicious categories and continuously update trust values in response to changing network conditions. Based on the predicted trust levels, adaptive security decisions are enforced to allow or restrict node participation in data sharing and computation processes. A quantitative experimental evaluation is conducted using simulated distributed IoT scenarios that include both normal and malicious behaviors. The performance of the proposed framework is evaluated using standard metrics such as accuracy, precision, recall, F1score, and detection effectiveness, and is compared against conventional static trust and rulebased security mechanisms. The results demonstrate that the proposed machine learningbased trust evaluation approach achieves significantly higher detection accuracy and robustness while maintaining low computational overhead. Overall, the findings confirm that integrating machine learning into trust management provides an effective and scalable solution for securing distributed IoT systems under dynamic and adversarial conditions.

Abstract

This research explores the application of Monte Carlo Simulation in estimating portfolio risk in the Indonesian stock market. The primary objective is to assess the effectiveness of this method in predicting portfolio return distribution and managing risk compared to traditional methods like Value at Risk (VaR). Data from the Indonesia Stock Exchange (IDX) were used to analyze stock returns, focusing on sectors such as telecommunications and property. Monte Carlo Simulation was applied to generate multiple scenarios of stock returns based on historical data and probabilistic distributions. The findings show that Monte Carlo Simulation provides a more comprehensive risk estimation, especially for stocks with high volatility and small market capitalization. Unlike VaR, which assumes a normal distribution, Monte Carlo Simulation accounts for extreme risk events and market uncertainties. The study also highlights the importance of diversification, as portfolios with a mix of high and low volatility stocks demonstrate a more stable risk profile. The results suggest that Monte Carlo Simulation is an effective tool for investors looking to manage risk in dynamic market conditions, providing more accurate and reliable estimations compared to traditional risk assessment methods. This research recommends further exploration of Monte Carlo Simulation in other sectors or with varied data for broader applications in risk management.

Abstract

This study examines the authority of curators in enforcing general seizure (sita umum) over objects of Sale and Purchase Binding Agreements (Perjanjian Pengikatan Jual Beli/PPJB) that have not been fully paid in the bankruptcy of a Limited Liability Company, based on the Commercial Court Decision No. 29/Pdt.Sus-GLL/2022/PN.Niaga.Jkt.Pst. The main issue addressed is whether unpaid PPJB objects may be included in the bankruptcy estate (boedel pailit) and the extent of the curator's authority in managing and settling such objects. This research employs a normative juridical method using statutory and case approaches by analyzing Law Number 37 of 2004 on Bankruptcy and Suspension of Debt Payment Obligations, along with relevant court decisions. The findings indicate that unpaid PPJB objects are, in principle, part of the bankruptcy estate since ownership rights have not been fully transferred, thereby granting the curator authority to impose general seizure and conduct management and settlement actions. Nevertheless, the exercise of such authority must consider the principles of justice and legal protection for good-faith buyers. The court's decision clarifies the legal standing of PPJB in bankruptcy proceedings and delineates the scope of the curator's authority.

Abstract

This paper tries to show how Indonesian economic law has evolved via the emergence of the cyber notary idea. Notaries engage in various everyday tasks and activities in the fantastic world development, such as giving the clients the finest service possible and impacting the economy. According to the law, notaries are required to be able to help and support anyone who requires genuine written documentation of legal situations, events, or activities. This study employs qualitative approaches and descriptive analysis. Additionally, researchers are interested in the phenomenon that examines the idea of a cyber notary as a way to advance Indonesian commercial law. Qualitative research aims to conduct extremely thorough investigations that examine the research's findings in great detail. Both primary data and secondary data are employed as sources of information. The findings demonstrate that cyber notary adds value to electronic documents by legalising them, for example, in addition to digitising notarial operations. However, because many aspects need to be ready, its implementation will take some time. Article 1868 of the Indonesian Civil Code stipulates that a genuine deed is a deed in a certain form that has been prescribed by law and is made before a public authority.

Abstract

This study aims to analyze the effect of entrepreneurial orientation on business performance, with innovation capability as a mediating variable, among Micro, Small, and Medium Enterprises (MSMEs) in Karanganyar Regency. The study employed a quantitative approach using a survey method administered to 200 MSME owners selected through purposive sampling. Data were collected via a questionnaire using a five-point Likert scale and analyzed using IBM SPSS Statistics through descriptive analysis, reliability testing, correlation analysis, linear regression, and the Sobel Test to examine the mediating effect. The results indicate that Entrepreneurial Orientation has a positive and significant effect on Innovation Capability, and that Innovation Capability has a positive and significant effect on Business Performance. Conversely, the direct effect of Entrepreneurial Orientation on Business Performance becomes insignificant after Innovation Capability is included in the model. The mediation test results show that Innovation Capability fully mediates the relationship between Entrepreneurial Orientation and Business Performance. These findings indicate that enhancing entrepreneurial orientation will be more effective in improving the performance of MSMEs if supported by adequate innovation capabilities. This study offers implications for the development of MSMEs through the strengthening of innovation capabilities as the primary mechanism for improving business performance.

Abstract

The accelerating digital transformation has intensified competition among small and medium-sized enterprises (SMEs), requiring firms to develop capabilities that extend beyond the adoption of digital technologies. This study aims to examine the roles of digital transformation capability and entrepreneurial orientation in improving SME performance through business agility as a mediating variable. A quantitative approach with an explanatory research design was employed, using a cross-sectional survey of SME owners or managers who had adopted digital technologies in their business activities. Data were collected through a Likert-scale questionnaire and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM), including measurement model, structural model, direct effect, and indirect effect assessments. The findings indicate that digital transformation capability strengthens SMEs’ ability to adapt to changes in the business environment, while entrepreneurial orientation enhances their capacity to identify and exploit emerging opportunities. Business agility plays an important role in translating these capabilities into improved SME performance by facilitating faster and more flexible responses to market changes. The study implies that SMEs should integrate digital capabilities, entrepreneurial orientation, and business agility rather than relying solely on technology adoption to strengthen sustainable performance and competitiveness.
