Mahkamah : Jurnal Riset Ilmu Hukum 2025 Asosiasi Peneliti dan Pengajar Ilmu Hukum Indonesia

The state has a mandate to guarantee citizens' freedom of expression by protecting symbolic representations in public spaces. However, legal construction in Indonesia tends to use the law as a tool to limit visual interpretation, including popular cultural symbols such as the One Piece flag. This study aims to explain two main aspects of the mechanism of symbol criminalization: the state's construction of symbols as threats without any basis in actual violations, and the political use of fear through the production of imaginary enemies. The research method employed a qualitative approach with a conceptual approach. The results show that the state's interpretation of visual symbols rests not on the legality of the action, but on controlling the potential meanings that develop outside the official narrative. Within this construction, the law operates as a filtering mechanism for forms of articulation deemed inconsistent with the state's ideological interests. This strategy shifts the focus from concrete violations to the surveillance of social imagination. Thus, the criminalization of symbols occurs not because of their factual content, but because they open up pathways of solidarity that cannot be institutionally controlled. A critical criminological approach demonstrates that the state uses the law to enforce symbolic domination through techniques of controlling meaning within a democratic regime that formally promises freedom of expression.

Criminal liability in modern law is built on the assumption that every individual is a rational and autonomous moral agent. However, neuroscientific evidence suggests that structural disruption of the amygdala and prefrontal cortex significantly impairs the capacity to judge actions ethically. This study aims to analyze the influence of neurological disorders on an individual's moral capacity and to formulate legal parameters for assessing criminal liability based on actual capacity. The research method employed normative legal research with a conceptual approach. The results indicate that perpetrators with dysfunction in the amygdala-PFC circuit experience a degradation of moral capacity that weakens the basis for the formation of mens rea in a substantive sense and falls outside the reach of legal systems that still rely on a model of responsibility based on the assumption of universal free will. The criminal legal system, in its current form, lacks a precise evaluative mechanism to distinguish between perpetrators with impaired moral control and those acting deliberatively. In this situation, the construction of criminal liability cannot be standardized, and reformulation of evaluation instruments is necessary to avoid sentencing bias against individuals with structural impairments in ethical capacity.

This paper aims to explore the legal basis and ethical reasoning for the revocation of parental rights due to domestic violence by placing the child's best interests as a compass and mapping the gap between norms and judicial practices. The method used is normative-doctrinal legal research based on a literature review of the Domestic Violence Law, the Marriage Law, the Child Protection Law, selected jurisprudence, and scientific literature, analyzed qualitatively through systematic interpretation, argument construction, and linking to the facts of the impact of domestic violence on children. The results show that positive law provides a firm basis for sanctions and protections including restrictions on interaction and revocation of custody rights, but implementation is often hampered by vague evidence of psychological violence, the victim's economic dependence, and weak execution of alimony; revocation effectively breaks the cycle when accompanied by a protection order, a post-decision parenting plan, and ongoing psychosocial support. Policy implications include guidelines for proving coercive control, expanding access to timely protection orders, integrating trauma-informed services in religious courts, and a mechanism for executing alimony that does not burden victims, with schools, community health centers, and communities as early detection nodes. Ultimately, legal work and social networks converge in one simple goal: that home again means a safe place for children to return.

The rapid advancement of science and technology requires universities to provide safe, comfortable, and representative learning facilities. One such initiative is the construction of a five-story lecture building at Dr. Soetomo University, designed with a steel structure as an alternative to reinforced concrete. Steel was chosen due to its high tensile strength, uniform material properties, lighter weight, ease of installation, and strong resistance to earthquake loads. This study aims to design a five-story lecture building with a steel structure that meets the requirements of strength, stability, and safety in accordance with applicable standards. The method applied is structural planning based on SNI 1729:2020, SNI 1727:2020, and SNI 1726:2019 using the Load and Resistance Factor Design (LRFD) approach. Structural analysis was conducted with SAP2000 version 2014 through three-dimensional modeling that considers geometry, material properties, loading, and placement. The results show that the selected steel profiles for beams, columns, and connections are capable of supporting the combination of dead loads, live loads, and seismic loads with safe performance. The maximum stress remains below the allowable limit, and the deflection values do not exceed the permitted deviation. These findings confirm that steel provides efficiency in dimensions and materials while offering practicality and earthquake resistance, and the design produced can serve as a useful reference for future multi-story building projects in earthquake-prone regions.

Concrete roof tiles are an important material in building construction, particularly for roofing work, due to their advantages in terms of strength, durability, and material availability. This study aims to analyze two main physical characteristics of concrete roof tiles, namely bending load and water absorption, using a literature review approach from various previous studies. Bending load refers to the material's ability to withstand bending forces, while water absorption describes the material's capacity to absorb and store water through its pores. These two properties significantly influence the quality and durability of roof tiles in facing external environmental conditions, especially wet-dry cycles and mechanical loads. The results of the literature review indicate that the use of waste as an aggregate substitute in concrete mixes can significantly improve the performance of concrete roof tiles. For example, research using broken roof tiles and ceramic waste as aggregate substitutes successfully increased flexural strength to a range of 12.5–15.0 MPa. Meanwhile, variations in water absorption were recorded in the range of 4%–8%, depending on the material composition and production method. This proves that the use of recycled materials not only supports sustainability but also improves the mechanical and physical properties of concrete roof tiles. Overall, this study underscores the importance of material innovation in concrete roof tile production, particularly utilizing waste as an alternative aggregate. However, further research is needed to explore the best combination of materials and production techniques for producing high-quality, efficient, and environmentally friendly concrete roof tiles.

This study examines how women construct their social roles in managing dual responsibilities and maintaining work life balance through participation in the Women’s Cycling Community (WCC) Bandung. Using the social construction theory of Peter L. Berger and Thomas Luckmann, which includes objectivation, externalization, and internalization, this research applies a qualitative method with a phenomenological approach. The key informants were members of WCC Bandung, while supporting informants included husbands, children, and a psychologist. Data were collected through in-depth interviews, observation, and documentation, then analyzed through the stages of data reduction, data presentation, and conclusion drawing with validity tested through triangulation and member checking. The findings show that women do not perceive dual roles as a burden but as an integral part of their identities. Family support, effective communication, and the presence of community are crucial in developing time management strategies and maintaining balance between domestic and professional responsibilities. The study also reveals that involvement in WCC Bandung provides women with a platform to express themselves, build solidarity, and gain emotional support from peers who share similar challenges. Cycling activities are not only a hobby but also serve as a medium for stress release, physical health improvement, and social networking. The study concludes that participation in WCC Bandung helps women construct an empowered, flexible, and harmonious self-identity through social support and a positive community environment, ultimately shaping a more holistic understanding of work life balance in their everyday lives.

Each workplace has a different potential risk of work accidents depending on the type of industry, technology used, and risk control efforts undertaken by the company. Work accidents are generally caused by two main factors: unsafe acts by humans and unsafe working conditions. In this context, occupational safety and health (K3) is an important aspect that must be implemented in every company to protect workers from hazards that can cause losses, both physical and work productivity. Law No. 13 of 2003 concerning Manpower mandates that every worker has the right to occupational safety protection. This study focuses on UD. Fuad Las Jaya, a company engaged in construction and welding services. This company has a fairly high potential for work accidents considering the type of work performed. Based on employee attendance data in 2025, there is a level of discipline that can be related to working conditions and perceived safety. The severity of accidents is classified into three categories: light, moderate, and severe, which indicates the importance of implementing an effective K3 system. It is hoped that consistent awareness and implementation of K3 will create a safe, healthy, and productive work environment, as well as reduce the number of work accidents in the construction sector.

Plagiarism in scientific writing is a serious violation that not only harms the original creator but also undermines academic integrity, the development of scientific knowledge, and the credibility of educational institutions. This research aims to analyze the regulation of plagiarism acts based on the laws and regulations in Indonesia, as well as to build a firmer criminal law construction against acts of plagiarism within academic settings. This study employs a normative juridical method with a doctrinal approach, examining relevant laws and legal theories. The findings indicate that although plagiarism has been regulated in several legal instruments such as the Indonesian Penal Code (KUHP), Law Number 28 of 2014 on Copyright, Law Number 20 of 2003 on the National Education System, and the Regulation of the Minister of National Education Number 17 of 2010, the existing regulations tend to be administrative in nature and have not provided a sufficient deterrent effect. Therefore, a more comprehensive and implementable criminal law construction is needed to ensure the protection of scientific works and legal certainty in the enforcement of criminal sanctions against perpetrators of plagiarism. In addition, preventive efforts through academic ethics education, the implementation of plagiarism detection systems, and the strengthening of internal policies within universities are also important steps that must be optimized.

The increase in traffic volume in urban areas often triggers various problems, especially at Road intersection points that have a high level of interaction between vehicles. One of the locations that experience these problems is the intersection with the island of traffic without signal on Jl. Tebu-Jl. Tabrani Ahmad, City Of Pontianak. This study aims to analyze the performance of the intersection in the existing condition and project its performance in the next five years (2030), as well as formulate alternative treatment that can improve the smoothness of traffic. The analysis method refers to Indonesian road capacity guidelines (PKJI) 2023 and modeling using software PTV VISSIM. The data collected include intersection geometry, traffic volume, and vehicle speed. Traffic volumes were obtained through CCTV recordings for three consecutive days, then processed and presented in the form of tables and graphs for easy interpretation. The results of the existing condition analysis showed that the degree of saturation (DS) reached 0.407 with an average delay of 9.539 seconds (Level of Service/LOS B) based on PKJI, while VISSIM simulation resulted in a delay of 12.54 seconds (LOS B). The five-year projection (2030) shows an increase in DS to 0.878 with a delay of 15.177 seconds (LOS C) from PKJI, and 23.35 seconds (LOS C) from VISSIM, which indicates a decrease in Junction performance as traffic grows. Two handling alternatives were analyzed, namely the construction of roundabouts and the implementation of traffic flow management. VISSIM simulation shows that the roundabout can reduce the delay to 14.31 seconds with a queue length of 20.34 m (LOS B), while the flow management produces a delay of 11.81 seconds with a queue of 13.14 m (LOS B). This result confirms that both alternatives are able to improve the performance of the intersection compared to the projected condition without handling, so that it can be a technical recommendation for urban traffic planning in Pontianak.
