Abstract:The discourse on casino legalization in Indonesia arises as a response to the widespread illegal gambling that remains difficult to eradicate despite being prohibited under the Criminal Code (KUHP), Law No. 7 of 1974, and…
d the Electronic Information and Transactions Law (ITE). The gap between legal norms (das sollen) and social reality (das sein) shows that prohibition alone has not been effective. This research uses a qualitative method with a normative juridical approach based on legislation and a comparative approach, particularly examining Malaysia and Singapore, which have successfully managed casinos through strict regulations. The findings indicate that casino legalization in Indonesia could serve as an alternative fiscal policy, provided that clear regulations are established, ensuring economic benefits such as increased state revenue and effective control over illegal gambling, without undermining national morals and values.

al violence from students’ parents, which undermine their dignity and safety in the educational environment. This study addresses the problem of how legal frameworks provide protection for teachers and whether existing regulations adequately ensure their rights and security. The research aims to analyze the effectiveness of legal protection for teachers under the Criminal Code, Law No. 14 of 2005 on Teachers and Lecturers, Law No. 35 of 2014 on Child Protection, and Ministerial Regulations concerning teacher protection. The study employs a normative juridical method with a statute, conceptual, and case approach, relying on primary, secondary, and tertiary legal materials, analyzed through qualitative interpretation and juridical argumentation. The results indicate that although legal instruments exist, their implementation remains weak due to the absence of technical regulations, limited institutional coordination, and insufficient support systems for teachers at the school level. The study concludes that derivative regulations and integrated mechanisms are essential for ensuring effective protection. It recommends strengthening inter-agency coordination, establishing school-level protection units, and enhancing teachers’ legal literacy.
Abstract:Freight forwarding agreements in Indonesia frequently contain exoneration clauses that exempt logistics providers from liability for loss or damage, raising serious concerns regarding consumer protection. While such clauses…
ses are designed to manage contractual risk, they often conflict with the principles enshrined in Law No. 8 of 1999 on Consumer Protection (UUPK), particularly those ensuring fairness, good faith, and legal accountability. This study investigates the legality and ethical implications of exoneration clauses within standard-form freight forwarding contracts used by companies such as JNE, TIKI, and SiCepat. Employing a doctrinal legal research methodology, the study integrates statutory, conceptual, and case-based approaches to analyze primary legislation, judicial decisions, and relevant legal doctrines. It critically evaluates the use of these clauses in light of consumer rights, contract theory, and the economic impact on service quality. Findings reveal that exoneration clauses not only contravene the UUPK but also create systemic contractual imbalances due to the lack of negotiation opportunities and transparency. The study proposes a normative legal framework for reform, including clause classification, interactive consent mechanisms, and regulatory enforcement to ensure contractual fairness. This research contributes to both legal scholarship and policy development by highlighting the urgent need for doctrinal clarity and regulatory oversight in Indonesia's logistics sector.

ee productivity and create a conducive work environment. Using quantitative methods, data were analyzed through regression tests, including T-test, F-test, and determination coefficient analysis, to explore the relationships between these variables. The results indicate that motivation has a strong and significant positive effect on employee performance, supported by a regression coefficient of 0.661 and a significance level of p < 0.001. Similarly, job satisfaction also significantly impacts performance, with a coefficient of 0.325 and p < 0.001, although its influence is comparatively lower than motivation. The simultaneous effect of motivation and job satisfaction was confirmed by an F-value of 396.748 and an R² of 0.922, indicating that 92.2% of the variation in employee performance can be explained by these two factors. The findings emphasize the importance of fostering both motivation and job satisfaction to improve employee performance effectively. Therefore, organizations should develop policies that enhance motivation through rewards and career development opportunities, as well as improve job satisfaction by ensuring supportive working conditions and recognizing employee contributions.
