Abstract

Improving students' academic performance is a primary focus in higher education, with discipline in studying being a key factor that affects academic success. However, many students face challenges in time management and developing effective study habits. Therefore, this community service activity aims to socialize strategies for enhancing academic performance through study discipline. The socialization was carried out through workshops and seminars, covering topics such as time management, effective learning techniques, intrinsic motivation, and the use of digital technology to support learning. The activity involved students from various majors selected through purposive sampling, focusing on students with lower to moderate GPAs and those who lacked effective study habits. The evaluation was conducted using both quantitative and qualitative methods. The results of the pre-test and post-test showed a significant improvement in students' understanding of study discipline, with an average score increase of 28.75 points. Qualitative evaluation also revealed positive changes in students' study habits, such as better time management, avoiding procrastination, and using digital tools like time management applications. Furthermore, the level of student satisfaction with the activity was high, reaching 86.25%, indicating that most students found the socialization activity highly beneficial. Based on these results, this activity proved effective in enhancing students' study discipline and can serve as a model for improving learning outcomes in higher education. Moving forward, it is recommended to provide follow-up sessions and continuous support to help students consistently apply study discipline in their academic lives.

Abstract

Globalization has had a significant impact on the harmonization of international and national laws, affecting areas such as trade, environment, and human rights. This study explores the impact of globalization on legal harmonization, identifying key drivers such as economic integration, technological advancement, and the role of international organizations. It also highlights emerging challenges, including legal pluralism, cultural resistance, and disparities in institutional capacity across countries. Using a qualitative approach, legal analysis is conducted to identify patterns of convergence and divergence across legal systems, including common law, civil law, and hybrid legal systems. Case studies such as the implementation of the Paris Agreement, the adaptation of WTO trade law standards, and the mainstreaming of human rights in developing countries reveal the success rates and obstacles in harmonization. The results show that while harmonization promotes global cooperation and reduces legal protection, challenges remain. Fragmentation of international law, geopolitical tensions, and differences in local values ​​are key barriers. To address these, the study recommends an adaptive framework, enhanced multilateral cooperation, and investment in developing country capacity building. In conclusion, legal harmonization requires a balance between global norms and local relevance, so as to create an inclusive and effective legal system. A collaborative approach involving stakeholders across borders is key to bridging the gap between international standards and national realities.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) have a strategic role in the Indonesian economy, but often face major challenges in business competition, especially with large companies. Unfair business competition practices, such as monopolies, predatory pricing, and cartels, often harm MSMEs. This study aims to analyze the legal protection available to MSMEs in facing business competition, the effectiveness of existing regulations, and obstacles in their implementation. The research method used is a normative approach with an analysis of applicable laws and regulations, as well as an empirical approach through case studies related to business competition policies in Indonesia. The results of the study show that although there are regulations such as Law Number 5 of 1999 concerning the Prohibition of Monopolistic Practices and Unfair Business Competition and Law Number 20 of 2008 concerning Micro, Small, and Medium Enterprises, the implementation of legal protection still faces various obstacles. Lack of socialization of regulations, low legal awareness among MSMEs, and limitations in supervision by the Business Competition Supervisory Commission (KPPU) are the main factors that hinder the effectiveness of legal protection. Therefore, reforms are needed in business competition policy, increasing legal literacy for MSMEs, and synergy between the government, KPPU, and MSME associations to create a fairer and more competitive business ecosystem

Abstract

The increasing use of electronic transactions in the digital age has raised significant concerns regarding consumer protection. Consumers face various risks, such as fraud, product mismatch, delivery delays, and misuse of personal data. This research aims to analyze the juridical framework governing consumer protection in electronic transactions, particularly in Indonesia, where digital commerce is rapidly expanding. By applying a normative juridical method and qualitative analysis, the study reviews existing legislation, including Law No. 8 of 1999 on Consumer Protection, and evaluates its effectiveness in addressing current digital challenges. Findings show that despite having a legal framework, the enforcement and application of consumer protection laws in digital transactions remain limited and inconsistent. Many platforms do not fully comply with legal requirements related to transparency, dispute resolution, and data protection. The study includes statistical data and visual aids such as charts and tables to illustrate the scale of consumer issues in the digital environment. It concludes that there is a need for legal reform, stronger regulatory oversight, and greater platform accountability. Additionally, increasing public awareness and utilizing Alternative Dispute Resolution (ADR) mechanisms can enhance consumer protection in the growing e-commerce ecosystem.

Abstract

The rapid advancement of blockchain technology and the emergence of the metaverse as a cross-border digital economy have triggered new legal challenges, particularly concerning smart contracts and virtual property disputes. Smart contracts—self-executing agreements coded on blockchain—offer efficiency and transparency but raise critical questions about legal validity, jurisdiction, and dispute resolution when conflicts arise between parties from different countries. In the context of virtual ownership such as digital land, NFTs, and in-world assets, diverging national legal systems complicate the enforcement of rights over virtual property. This study analyzes how smart contracts are utilized in virtual property transactions and examines the evolving international legal approaches to disputes arising from such agreements. The research highlights the urgent need for an adaptive global legal framework, cross-jurisdictional recognition of digital rights, and the role of blockchain-based arbitration bodies as alternatives to traditional dispute resolution. It also explores the relevance of traditional contract law principles in decentralized virtual environments and the regulatory challenges related to digital identity and evidentiary standards. With a multidisciplinary approach, this abstract offers insights into the importance of legal harmonization and international collaboration in supporting a fair, predictable, and legally secure metaverse ecosystem.

Abstract

Corporate bankruptcy prediction is a critical task in financial risk management, particularly under conditions of economic uncertainty and highly imbalanced datasets. This study presents a comprehensive benchmarking framework that evaluates multiple supervised learning models and a voting ensemble approach for corporate bankruptcy prediction. Using a publicly available dataset comprising 78,682 financial records from US-listed companies on NYSE and NASDAQ (1999-2018), we compare the performance of Random Forest, XGBoost, Gradient Boosting, Support Vector Machine, Decision Tree, and a Voting Classifier. Extensive preprocessing, including outlier removal, normalization, and feature selection, and cost-sensitive learning to mitigate severe class imbalance was conducted to ensure data quality. Model performance was assessed using multiple evaluation metrics such as accuracy, F1-score, and ROC AUC to account for class imbalance. Results demonstrate that the Voting Classifier, integrating Random Forest, XGBoost, and Gradient Boosting via hard voting, achieves superior overall performance with an accuracy of 93.6%, F1-score of 96.5%, and ROC AUC of 82.6%, outperforming individual models. The findings underscore the value of ensemble approaches in improving prediction robustness while addressing class imbalance challenges in financial distress forecasting. This study contributes a reproducible experimental design that can guide future research and practical implementation of learning models in corporate bankruptcy risk assessment.
