In the modern computing era, servers face significant challenges in data storage due to hardware failures, cyber attacks, or human errors. The problem highlighted focuses on the impact of file systems on three critical aspects: data integrity (accuracy and consistency of data without corruption), data recovery (the ability to restore data after a failure), and failure resilience (fault tolerance, such as redundancy and journaling to prevent downtime). The main issue is that traditional file systems like FAT32 or NTFS are often susceptible to fragmentation, metadata loss, or long recovery times, which can lead to data loss of up to 20-30% on enterprise servers, especially in high-traffic environments like cloud computing.A simple problem-solving process is conducted through a straightforward comparative analysis approach: (1) A literature review of popular file systems (ext4, ZFS, Btrfs); (2) Failure simulations using tools like fsck and stress testing on virtual servers (e.g., via KVM or Docker); and (3) Measuring performance metrics with benchmarking tools like Bonnie++ for I/O throughput, recovery time, and error rates. This process is designed to be simple, requiring only a virtual lab setup without expensive hardware, and is analyzed quantitatively with descriptive statistics.The solution to the problem indicates that advanced file systems like ZFS or Btrfs provide significant improvements: data integrity is up to 95% more secure through automatic checksums, data recovery is achieved in minutes through snapshots and RAID integration, and failure resilience is higher with copy-on-write features. The main recommendation is to migrate to journaling-based file systems for servers, combined with automated backups, which can reduce the risk of downtime by up to 50%. This research provides practical guidance for system administrators to enhance server reliability without excessive additional costs.

This study aims to examine public minibus drivers in Medan from the perspectives of citizenship and liberalism. The research method used is descriptive qualitative with data collection techniques through in-depth interviews, participatory observation, and documentation. The results show that public minibus drivers enjoy individual freedoms, such as determining their working hours, choosing their rest times, and competing for passengers. This freedom is seen as a form of self-sovereignty in line with the principles of liberalism. However, this freedom also gives rise to contradictions, namely economic uncertainty, the burden of daily deposits, and the absence of social security and legal protection. The emergence of application-based transportation services further exacerbates the gap, as angkot drivers feel they experience inequality in terms of access to technology, regulations, and government support. This condition demonstrates the weak role of the state in guaranteeing their citizenship rights, especially those related to welfare and job protection. Thus, this study emphasizes that the principle of freedom in liberalism cannot be separated from the state's responsibility to achieve social justice. More equitable policies, technological support, and social protection for public minibus drivers are important steps to ensure that individual freedom is in line with citizenship rights.

This study explores the effectiveness of restorative and civil governance models in resolving environmental disputes at the local government level. As environmental conflicts become more complex and widespread, traditional legal approaches often fail to provide quick, sustainable solutions. Restorative governance models, which prioritize community involvement, collaboration, and the restoration of relationships, offer a promising alternative to adversarial legal proceedings. The research combines policy analysis and semi-structured interviews with local government officials, mediators, and community representatives to assess the implementation and outcomes of these models in real-world contexts. Findings indicate that restorative practices, when integrated with civil governance mechanisms, significantly reduce dispute resolution times (a 40% improvement) and enhance community satisfaction compared to traditional litigation processes. These models foster a more inclusive and cooperative environment, ensuring that all stakeholders, including local communities, are actively involved in decision-making processes. However, challenges such as legal framework rigidity, political pressures, and resource limitations still impede the widespread adoption of restorative practices. The study concludes with recommendations for integrating restorative approaches into local environmental policies, advocating for legal reforms and enhanced resource allocation to support these methods. Limitations of the study include its regional focus and the need for broader, longitudinal research to assess the scalability of restorative and civil governance models across different geographic contexts and environmental issues.

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 SENABUNG Serang Volunteer Community has various humanitarian programs to help the poor, street children, and other communities in need. This study aims to determine the communication strategy of the SENABUNG Serang Volunteer Community in increasing its presence in the community, as well as to analyze the obstacles faced. The research method uses a descriptive qualitative approach with the Resource Mobilization theory. Data were obtained through interviews, observation, and documentation. Data validity techniques use source triangulation to ensure the validity of the research findings. The results show that the existence of the SENABUNG community is built through the mobilization of five types of resources, namely human, material, organizational, socio-cultural, and moral resources. The community has succeeded in mobilizing volunteers, collecting donations, building social networks, and gaining moral legitimacy from the community. However, this study also found internal obstacles such as limited volunteers and time, inadequate equipment, unstable morale and transportation facilities, as well as external obstacles such as dependence on donations and digital security threats.

Moreover, the volunteers' time commitment is often restricted, limiting their capacity to engage fully. Additionally, inadequate equipment and unstable morale present further hurdles. Externally, the community's reliance on donations for funding leaves it vulnerable to fluctuations in contributions, and digital security threats pose risks to the integrity of the information shared across platforms.

This study aims to examine and analyze how the implementation of Standard Operating Procedures (SOP) impacts employee performance improvement at Chatter Lounge Restaurant, Gumaya Tower Semarang. The background of this research stems from initial observations and interviews that revealed inconsistencies in SOP implementation, particularly in aspects of grooming and staff attitudes toward guests. A qualitative descriptive method with a case study approach was employed to gain a comprehensive understanding of the phenomenon. Data were collected through in-depth interviews with four key informants, direct observations of operational activities, and digital documentation related to SOP practices. The data analysis followed the interactive model of Miles and Huberman, which includes three main stages: data reduction, data display, and conclusion drawing. The findings indicate that SOP implementation positively contributes to enhancing employee discipline, time efficiency, and accuracy in following service procedures, leading to a more standardized service quality. Nevertheless, the implementation is not yet fully optimal as several employees lack a comprehensive understanding of SOP content. Inhibiting factors include limited advanced training opportunities, one-way briefings that restrict interactive communication, and the absence of a performance-based reward system to motivate staff. The study highlights that while SOPs serve as a crucial guideline to improve consistency and professionalism, their effectiveness depends heavily on continuous reinforcement and employee engagement. Therefore, it is recommended that the restaurant management strengthen SOP implementation through ongoing training, more participatory internal communication, and the establishment of performance-based reward mechanisms to maximize employee motivation, ensure service excellence, and ultimately enhance guest satisfaction.

Conventional robotic surgical systems, while offering enhanced dexterity and 3D visualization, suffer from a critical limitation: the absence of tactile sensation. This sensory disconnect can lead to inadvertent tissue damage from excessive force application and complicates delicate maneuvers that rely on the surgeon's sense of touch. This research proposes and validates a novel surgical robotic system architecture designed to bridge this sensory gap by integrating high-fidelity 3D visual input with accurate, real-time force feedback from tactile sensors mounted on the end-effector. To rigorously evaluate this innovation, a structured comparative methodology was employed. A cohort of surgeons performed standardized surgical tasks, including suturing and tissue manipulation, on realistic soft-tissue phantoms. The performance of a conventional (visual-only) system was benchmarked against that of the proposed (visual-haptic) system. A comprehensive dataset was collected, which included objective metrics such as task completion time, precision deviation from the ideal tool path, and the magnitude of applied forces. Concurrently, subjective evaluations from the participating surgeons were gathered to assess perceived control, cognitive workload, and overall task confidence. The test data revealed statistically significant improvements when using the visual-haptic system. Participants not only completed tasks with greater speed and accuracy but also applied considerably lower and more consistent forces. The analysis underscores that haptic feedback, enabled by advanced sensor fusion, not only restores a crucial 'sense of touch' to the surgeon but also reduces the incidence of excessive force application, potentially minimizing tissue trauma and improving patient recovery. These findings confirm the hypothesis that haptic-visual integration constitutes a new paradigm in robotic surgery, shifting the paradigm from purely visual guidance to a more intuitive, multi-sensory surgical experience. This study also discusses future challenges and opportunities, including the potential for AI-driven partial autonomy, such as creating virtual safety boundaries or automating sub-tasks, and the development of next-generation sensor technologies to further enhance clinical outcomes.
