The rapid rise of Indonesia’s digital economy is changing how people participate as citizens and how their consumer rights are protected. This study explores the legal dimensions of digital citizenship through a normative juridical review of the Consumer Protection Law, the Electronic Information and Transactions Law, and the Personal Data Protection Law. Although these laws provide basic safeguards, significant problems remain such as data privacy violations, unclear algorithmic practices, cross-border legal barriers, and deceptive online advertising. Low public legal awareness and the absence of a unified dispute-resolution system further leave consumers vulnerable to powerful global digital platforms. The study argues that stronger protection requires embedding digital citizenship principles into Indonesia’s legal framework, harmonizing national rules with international standards, enhancing platform oversight, and improving digital literacy. In conclusion, a flexible and forward-looking legal approach is crucial to making consumer protection a core part of digital citizenship and ensuring public trust and human rights in the digital era.

Sexual violence within the family is a serious criminal act that not only violates the law but also causes profound physical and psychological suffering for victims. The complexity of such cases increases as the perpetrators are often close family members, resulting in trauma and obstacles in law enforcement. Decision Number 2068/Pid.Sus/2020/PN.Medan serves as the basis for analyzing the extent to which legal protection can be provided to victims. The research problems addressed are: (1) what forms of legal protection are available for victims of sexual violence within the family under Indonesian positive law, and (2) how such protection is implemented in Decision Number 2068/Pid.Sus/2020/PN.Medan. The research method applied is normative juridical with statutory, conceptual, and case study approaches. Data sources include legislation, legal literature, and court decision analysis. The findings reveal that legal protection for victims is regulated under the Child Protection Law, the Criminal Code, and other legal instruments emphasizing preventive, repressive, and rehabilitative measures. The Medan District Court imposed a severe sentence on the perpetrator in accordance with the law; however, protection for victims remains limited to formal aspects without comprehensive psychological recovery programs. In conclusion, the protection of victims of sexual violence within the family has been clearly regulated on a normative basis, but its implementation remains weak. Greater collaboration between law enforcement authorities, child protection institutions, and professionals is necessary to ensure the holistic recovery of victims.

Moral learning in junior high schools often faces challenges in improving the understanding and application of moral values in everyday life, especially in the material of Trustworthiness and Honesty. This paper is intended to explain the design of the Problem-based learning (PBL) learning method as an innovation in moral learning of the material of Trustworthiness and Honesty in class VIII of SMP Muhammadiyah 4 Panarukan, which is expected to improve students' understanding through a more contextual, active, and applicable learning experience. The PBL method allows students to analyze real problems related to Trustworthiness and Honesty, develop solutions, and reflect on the application of these values in everyday life. This learning design method adopts two stages of the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model, namely the needs analysis stage and the learning design stage. The results of the study indicate that the need for moral learning in class VIII of junior high school includes the importance of more interactive and problem-based methods, which can bridge the gap between moral theory and its application in real life. This PBL learning design integrates case studies, group discussions, and reflection to create meaningful learning experiences related to the values of Trustworthiness and Honesty. Although this design has considered various pedagogical and contextual aspects, the method is still in the design stage and has not been directly implemented or evaluated. Therefore, further research is needed to test the effectiveness of the PBL method in the context of moral learning at SMP Muhammadiyah 4 Panarukan.

Murder committed by children presents a dilemma in the criminal justice system, as it must balance the enforcement of justice with the protection of children's rights. This article examines the problematic nature of juvenile criminal liability in murder by comparing the perpetrator's legal approach to that of adults. Normative juridical research methods are used to explain legal provisions, court decisions, and related doctrines. The results indicate that juvenile offenders are not solely focused on their culpability but also on the child's psychological capabilities, maturity level, and social circumstances. Meanwhile, adult offenders are held fully accountable, with a focus on punishment. The main challenges are the difficulty of proving intent and the need for special mechanisms for handling juvenile offenders of serious crimes. This study provides for strengthening the capacity of law enforcement, improving child rehabilitation facilities, optimizing diversion mechanisms, and educating the public to support humane and proportional protection and enforcement of justice.

Diabetes mellitus is one of the health problems whose incidence is increasing and is often complained about by people around the world. Globally, Indonesia ranks fifth in the number of diabetes mellitus cases with 19.5 million people. Dietary patterns, including energy intake, carbohydrates, protein, fat, and nutritional status, play a role in the incidence of diabetes mellitus. The purpose of this study was to determine the relationship between dietary patterns and nutritional status with the incidence of diabetes mellitus at the Bahteramas Regional General Hospital in Southeast Sulawesi Province. The study design used a cross-sectional method with purposive sampling. The study respondents were inpatients aged ≥ 20 years. Data analysis used the chi-square test. The study was conducted in April-May 2025. The results of the analysis showed that there was a significant relationship between dietary patterns (p=0.008) and the incidence of diabetes mellitus. However, no significant relationship was found between nutritional status (p=0.421) and the incidence of diabetes mellitus. Thus, it is important to pay attention to nutrient consumption patterns and nutritional status in the prevention and management of diabetes mellitus.

The growth in the number of vehicles in Surabaya has led to increased traffic congestion, particularly on the Perak Timur–Perak Barat road section, which serves as a major distribution route to the port and industrial areas. Problems arise at U-Turn points, where vehicle accumulation hampers traffic flow. This study analyzes traffic volume, travel time, queue length, and queue ratio at two U-Turn points on this section. The method used was a field survey with direct observation of vehicle volume every 15 minutes, vehicle classification, and queue length. Traffic volume was calculated using the Passenger Car Equivalent (PCE) factor based on the 1997 MKJI standards. The study results show that at Point 1, east–west direction, the highest queue ratio occurred on Tuesday from 11:00 to 12:00 (p = 4.84), while the lowest was on Sunday from 06:00 to 07:00 (p = 0.21). At Point 2, west–east direction, the highest queue ratio occurred on Tuesday from 08:00 to 09:00 (p = 6.18), and the lowest from 06:00 to 07:00 (p = 0.41). These findings indicate that during peak hours, traffic congestion increases (p > 1), causing long queues, particularly in the west–east direction in the morning. The performance of the U-Turn on the Perak Timur–Perak Barat road section needs improvement, with recommendations such as temporarily closing U-Turns during high volumes, providing alternative U-Turn lanes, and adding signs to minimize the potential for vehicle conflicts.
