The growing number of alleged medical malpractice cases in Indonesia, particularly physicians’ misdiagnosis resulting in patient death, underscores the need for stronger legal certainty and accountability in healthcare services. Physicians are professionally obligated to conduct diagnosis and medical treatment in accordance with professional standards, service standards, and standard operating procedures; however, negligence may occur and lead to severe harm. This study aims to analyze the legal provisions governing physicians’ liability for misdiagnosis causing patient death and to examine the forms of legal responsibility that may be imposed. The research applies a normative juridical method using a case approach and literature review, relying on primary legal materials such as the Indonesian Civil Code, the Criminal Code, the Medical Practice Law, the Hospital Law, and Law Number 17 of 2023 on Health, supported by secondary and tertiary sources. The findings indicate that physicians may be held liable under civil, criminal, and administrative law if the essential elements of medical negligence are proven, namely duty of care, breach of duty, harm (including death), and a causal relationship between the misdiagnosis and the fatal outcome. Moreover, liability may extend to hospitals under the doctrines of vicarious liability, hospital liability, and strict liability. This study implies the importance of strengthening professional competence, reinforcing disciplinary mechanisms, and ensuring balanced legal protection for both patients and healthcare professionals within Indonesia’s health law framework.

This study discusses the function of corporate criminal liability for State-Owned Enterprises (SOEs), particularly SOEs, by examining a case of corruption in the sale of commodities at Perum Bulog Jakarta in 2022-2023, which caused financial losses to the state amounting to approximately IDR 7.192 billion. This case illustrates the abuse of authority by SOE officials, which not only reflects individual violations but also is a symptom of weaknesses in the culture of internal control and compliance in state-owned companies. The purpose of this study is to examine the regulation and application of the principle of corporate criminal liability in State-Owned Enterprises (SOEs) with reference to Law Law Number 31 of 1999 in conjunction with Law Number 20 of 2001 concerning Eradication of Corruption Crimes, the latest Criminal Code (Law Number 1 of 2023), and Supreme Court Regulation Number 13 of 2016. The method used is normative legal research with a juridical approach, which focuses on the review of legislation, the concept of corporate criminal liability, and the analysis of related court decisions. The results of the study show that acts of corruption involving Bulog have fulfilled the elements of corporate criminal liability, because they were carried out in the exercise of official authority and were intended for the benefit of the institution. The application of the provisions in the new Criminal Code, particularly Articles 45 to 47 and Article 118, confirms the position of corporations as legal subjects in the criminal law system. The implications of this research highlight the need to strengthen the Good Corporate Governance (GCG) system in SOEs and the need for consistent enforcement of corporate criminal liability by law enforcement officials to ensure justice, transparency, and the prevention of structural corruption in Indonesia.

This study aims to evaluate the implementation of Sidoarjo Regent Regulation Number 69 of 2017 concerning the Civil Servant Code of Ethics in the Family Planning Sector at the Sidoarjo Regency Women's Empowerment, Child Protection, and Family Planning Office. A qualitative approach with a case study was used to explore the implementation of the policy through interviews, observation, and documentation. The analysis was conducted using William Dunn's six policy evaluation indicators, namely effectiveness, efficiency, adequacy, equity, responsiveness, and accuracy. The results show that the policy has provided clear behavioral guidelines and is applied evenly in the work environment. However, the effectiveness and efficiency of implementation are not optimal due to disciplinary violations, weak supervision, and unstructured communication between superiors. The aspects of adequacy and accuracy are considered relevant to the needs of the organization, but have not been able to fully overcome obstacles such as high workloads and low internalization of ethical values ​​among employees. In general, this policy contributes to shaping the professionalism of civil servants, but still requires strengthening through continuous supervision and more systematic coaching. The originality of the study lies in the use of Dunn's evaluation model in the context of the implementation of the civil servant code of ethics at the regional level, as well as identifying gaps between normative policies and field practices. These findings confirm that the success of a code of ethics depends heavily on organizational communication, work culture, and consistency of oversight.

This study discusses the position of persons with disabilities, especially those with mental and intellectual disabilities, in carrying out legal actions following the judicial review of Article 433 of the Civil Code through the Constitutional Court Decision Number 93/PUU-XX/2022. Prior to this amendment, Article 433 of the Civil Code used discriminatory terms and automatically placed persons with disabilities under guardianship, thereby eliminating their legal capacity as independent legal subjects. This Constitutional Court decision changed the phrase "must be guarded" to "can be guarded" and emphasized that the placement of guardianship can only be made based on a competent medical diagnosis. The research method used is normative juridical through a statutory approach and court decisions. The results of the study show that the change in norms restores the constitutional rights of persons with disabilities, including the right to autonomy, equality before the law, and protection from discrimination. In addition, this change directly affects the requirements for capacity in making agreements according to Article 1320 of the Civil Code, so that persons with mental disabilities who have the capacity are still considered capable of acting. Therefore, this decision is an important step in realizing a legal system that is more inclusive, just and respects the dignity of people with disabilities.

The reform of criminal law in Indonesia has become an increasingly urgent necessity in line with social developments, technological advancement, and the growing complexity and diversity of crime. Law Number 1 of 2023 concerning the new Criminal Code (Kitab Undang-Undang Hukum Pidana/KUHP) emerges as a comprehensive effort to replace the colonial-era Criminal Code and to align the national criminal law system with the current conditions of Indonesian society. This new Criminal Code introduces several significant changes, including the regulation of cybercrime, protection of the environment, the reinforcement of humanitarian values, and the strengthening of the principle of limiting criminal sanctions on individual liberty in order to ensure the protection of human rights. This paper aims to analyze the direction and substance of the Criminal Code reform, evaluate its potential implementation, and assess the implications of these changes for criminal law enforcement practices in Indonesia. The research method employed is a literature review using a normative approach, conducted through the analysis of statutory regulations, criminal law theories, and relevant case studies. The results of the analysis indicate that the new Criminal Code provides a more adaptive and responsive legal framework to contemporary issues; however, the effectiveness of its implementation largely depends on the readiness of law enforcement authorities, the intensity of regulatory socialization, and the level of public legal awareness. This study concludes that criminal law reform represents a strategic step toward realizing a criminal justice system that is more just, effective, and aligned with the values of Pancasila.

The enactment of Law Number 1 of 2023 concerning the Criminal Code introduces the criminalization of cohabitation under Article 412, sparking public debate regarding state intervention in private spheres. This research aims to analyze the challenges faced by law enforcement in implementing cohabitation regulations within Indonesia’s pluralistic society. Utilizing a normative judicial research method with statute and conceptual approaches, this study examines secondary legal data including the New Criminal Code and various legal doctrines. The findings indicate that while Article 412 is designed as an absolute complaint-based offense to balance institutional marriage protection with individual privacy, its implementation faces substantial sociological hurdles. These challenges include potential conflicts with living law such as customary and religious norms, risks of over-criminalization, and the threat of social vigilantism due to public misinterpretation. This research implies that law enforcement must prioritize restorative justice and intensive socialization to prevent human rights violations and maintain social harmony in a diverse cultural landscape.

The protection of suspects’ rights during the investigation phase is a fundamental component of a fair and effective criminal justice system. This study examines the implementation of the principle of due process of law in Indonesia and its implications for safeguarding human rights in criminal investigations. Utilizing a normative legal research approach, supported by statutory and conceptual analysis, the research evaluates both the legal framework and practical application of suspects’ rights under the Indonesian Criminal Procedure Code (KUHAP), the 1945 Constitution, and international human rights instruments such as the ICCPR. Findings indicate that while Indonesia has established comprehensive regulations to protect suspects, the practical implementation remains inconsistent due to structural, cultural, and procedural challenges. Deviations such as limited access to legal counsel, incomplete documentation of interrogations, and occasional coercive practices undermine adherence to due process standards. The study highlights the critical need for regulatory improvements, capacity building for investigators, and strengthened supervision mechanisms to ensure full protection of suspects’ rights. Enhancing the conformity of investigative practices with due process principles is essential not only for safeguarding individual rights but also for maintaining public trust and the integrity of the Indonesian criminal justice system.

The rapid development of information technology has significantly increased the practice of online buying and selling as part of electronic commerce (e-commerce). One of the payment methods widely used in online transactions is cash on delivery (COD), in which payment is made by the consumer at the time the goods are received. Although the COD system provides convenience and a sense of security for consumers, in practice it often gives rise to legal problems, particularly unilateral cancellations by consumers. Such cancellations are frequently carried out after the goods have been shipped or have arrived at the destination address, resulting in material and non-material losses for business actors. This condition indicates an imbalance in legal protection between consumers and business actors in online transactions using the COD system. This study aims to analyze the mechanism of implementing the COD payment system in online buying and selling transactions and to examine the forms of legal protection available for business actors affected by unilateral cancellations by consumers. This research employs an empirical juridical method, also known as sociological legal research, with a field research approach to examine the application of law in practice, particularly in Jambi City. Data were collected through literature review and interviews and analyzed qualitatively. The findings of this study are expected to contribute to the development of legal regulation and to strengthen legal certainty and protection for business actors in online transactions.

The increasing number of malpractice cases in Indonesia, particularly those related to misdiagnosis by medical practitioners, highlights the urgency of law enforcement in the health sector. This study aims to analyze the legal provisions and forms of physician liability for misdiagnosis resulting in patient death. The research employs a normative juridical approach with a library research method, using primary legal materials such as Law Number 17 of 2023 on Health, the Criminal Code (KUHP), and the Civil Code (KUHPerdata), as well as secondary legal materials including literature and legal health journals. The findings indicate that misdiagnosis proven to constitute professional negligence (culpa) may give rise to legal liability in three areas—criminal, civil, and administrative. Criminally, Article 440 of Law Number 17 of 2023 stipulates sanctions for medical personnel whose negligence causes serious injury or death (Republic of Indonesia, 2023). Furthermore, hospitals also bear responsibility under the doctrines of vicarious liability and hospital liability for the actions of medical practitioners under their supervision (Balubun, Simanjuntak, & Ginting, 2018). This research implies the need for a balanced legal protection framework between patients’ rights and the professional rights of medical practitioners, as well as the strengthening of medical supervision systems within healthcare institutions.

The investigation stage constitutes a crucial phase in the criminal justice system, as it determines the direction and quality of subsequent law enforcement processes. Within the context of Indonesian criminal procedural law, the Criminal Procedure Code (Kitab Undang-Undang Hukum Acara Pidana/KUHAP) grants extensive authority to law enforcement officials, particularly investigators, in order to ensure the effective disclosure of criminal offenses. However, such dominance of authority has the potential to create an imbalance between the interest of law enforcement effectiveness and the protection of human rights, especially when it is not accompanied by adequate mechanisms of limitation and oversight. This study aims to critically analyze the dominance of law enforcement authority at the investigation stage and its implications for law enforcement effectiveness and the potential for abuse of power. The research employs normative legal research using statutory and conceptual approaches, supported by qualitative analysis of legal doctrines, legislation, and relevant academic literature. The findings indicate that while the dominance of investigative authority does contribute to the effectiveness of investigations, it simultaneously creates opportunities for abuse of power due to weak internal and external oversight mechanisms. This condition results in the erosion of the principles of due process of law and the protection of suspects’ rights within the criminal justice system. Therefore, this study emphasizes the need to strengthen judicial control mechanisms, enhance the accountability of law enforcement officials, and reform criminal procedural law in order to achieve a balance between effective law enforcement and the protection of human rights within a democratic rule-of-law state.

This study aims to analyze the factors causing the differences in legal treatment and their implications on the principles of equality before the law, legal certainty, and the principle of legality. The method used is empirical legal research with a juridical-sociological approach. This study involves case studies, interviews with law enforcement officers and victim advocates, as well as an analysis of regulations and court decisions. The results indicate that the differences in legal treatment are caused by the application of subjective detention requirements in the Criminal Procedure Code (KUHAP), law enforcement discretion, differing legal interpretations between prosecutors and judges, the quality of legal assistance for defendants, and social pressures and societal dynamics. The impact of these differences is the failure to achieve substantive justice, weakening legal certainty, and declining public trust in the criminal justice system. This research has significant academic urgency as it contributes to the development of the enforcement of laws regarding Human Trafficking (TPPO), emphasizing the need for consistency, transparency, and the protection of victims' rights in the application of criminal law.

The Criminal Procedure Code (KUHAP) regulates three types of decisions that may be rendered by judges in criminal proceedings. A legal issue arises in situations where a defendant is proven guilty lawfully and convincingly, yet the imposition of a criminal punishment would create a conflict between legal certainty and legal justice. Article 54 paragraph (2) of Law Number 1 of 2023 concerning the Criminal Code (KUHP) introduces a new principle known as Rechtelijk Pardon, or what is referred to as a judicial pardon ruling. This provision offers guidelines for sentencing by considering various factors related to justice and humanity. Following the reform of the Criminal Code through the inclusion of this provision, there emerges a need to reform the Criminal Procedure Code as well, specifically by incorporating the judicial pardon decision into Article 191 of KUHAP. This research employs a normative legal research method using primary and secondary data sources. The research approach utilizes statutory and conceptual approaches. The results of the study emphasize the importance of adding the judicial pardon decision to Article 191 of KUHAP so that the reform of criminal law in Indonesia maintains coherence between substantive and procedural legal reforms, thereby creating a criminal justice system that is more just, humane, and responsive to societal needs.

This study compares the scalability and maintainability of three prominent programming paradigms-functional programming (FP), object-oriented programming (OOP), and declarative programming (DP)-in the context of distributed data processing systems. The research aims to evaluate how each paradigm performs under increased data volume and its ability to handle complex operations, while also assessing the ease of maintenance through code readability, modularity, and the flexibility of updating and debugging. The study employs a comparative experimental design, implementing identical data processing tasks, such as data aggregation, filtering, and transformation, across each paradigm. Key findings indicate that FP and DP outperform OOP in terms of scalability, with their stateless nature and high-level abstractions enabling efficient parallel processing and task distribution. FP, with its emphasis on immutability and concurrency, and DP, with its focus on describing desired outcomes rather than implementation specifics, both demonstrate superior performance in handling large datasets. However, while OOP excels in modularity and flexibility, its reliance on mutable state and shared resources hampers its scalability in distributed environments. In terms of maintainability, both FP and DP offer clearer, more maintainable code due to their abstraction levels, making them easier to update and extend. OOP, while modular, presents challenges in managing mutable state, complicating maintenance. This paper concludes with practical recommendations for developers on when to use each paradigm based on system requirements and suggests areas for future research, such as hybrid paradigms and long-term maintainability studies in real-world applications.
