Abstract

Ship stability failure contributes significantly to global maritime accidents, particularly container ship capsizing due to cargo shift and ballast imbalance. This study analyzes the effect of changes in the center of gravity (G) on ship stability on the MV Meratus Larantuka, a domestic feeder container ship on the Eastern Indonesia route. Using a descriptive qualitative methodology, data collection included participatory observation of the loading and unloading process, clinometer readings, draft measurements, and semi-structured interviews with four senior officers (Master, Chief Officer, Chief Engineer, OOW) during sea practice in January 2026. Data analysis followed the Miles and Huberman model with iterative reduction-presentation-verification and source triangulation. The findings revealed that bay plan deviation caused a transverse shift of G of 1.2 meters, unbalanced ballast resulted in a virtual increase of G of 0.35 meters through the free surface effect, and uneven freshwater consumption triggered a 0.5 meter trim by bow. Stability calculations showed a reduction in GM from 0.85 m to 0.62 m with a 12 percent loss of GZ curve area, although remaining within IMO criteria through counter-ballasting. The conclusions emphasized optimization of real-time PlanMaster and daily ballast rotation SOPs to reduce the stability risk by 50 percent on the choppy Sulawesi route.

Abstract

Sailing safety on passenger ships such as KMP Jambo VIII is often threatened by lifeboat failure due to suboptimal maintenance, even though the Plan Maintenance System (PMS) has been implemented. This study aims to analyze the implementation of the PMS function on lifeboats and identify its obstacles to supporting sailing safety. This type of qualitative descriptive research was conducted on the KMP Jambo VIII crew population with a purposive sample of 4 key informants (Captain, Chief Officer, Pumpman, Boatswain). The main research instruments were supported by semi-structured interview guidelines, observation sheets, and documentation; data analysis used the Miles and Huberman model (reduction, presentation, conclusion). The results show that the PMS runs through tiered inspections despite being hampered by a busy operational schedule, scarcity of spare parts, and administrative-field gaps. The conclusion recommends regular crew training and PMS digitalization for safety optimization.

Abstract

This study is motivated by the dynamics of population and poverty in Aceh Province, which have the potential to influence regional economic growth. Increases in population and reductions in poverty do not always correspond with optimal acceleration of economic growth, necessitating an empirical study to understand the relationship among these three variables. The objective of this research is to analyze the influence of population size and poverty on economic growth in Aceh Province, both partially and simultaneously. This study employs a quantitative approach using secondary time-series data from 1995 to 2024, obtained from the Central Statistics Agency. The analysis is conducted using a multiple linear regression model, complemented by classical assumption tests and hypothesis testing. The results indicate that, partially, population size has a significant effect on economic growth, with a regression coefficient of 6.546. Similarly, poverty significantly affects economic growth, albeit with a lower coefficient of 1.079. Simultaneously, population size and poverty together have a significant impact on economic growth, with a coefficient of determination (R²) of 0.942. These findings suggest that increasing population and addressing poverty in an integrated manner are important factors in promoting economic growth in Aceh. This study recommends that local governments design balanced development policies, optimize demographic potential, and strengthen poverty alleviation programs to support sustainable economic growth.

Abstract

Traditional hierarchical organizations prove increasingly inadequate confronting volatile, uncertain, complex, and ambiguous (VUCA) environments necessitating radical structural transformation toward agile, network, and platform-based models.This systematic literature review synthesizes empirical evidence examining transformation pathways, implementation challenges, and performance outcomes across these three organizational archetypes. Following rigorous review protocols, comprehensive search across academic databases yielded 24 peer-reviewed publications (2015-2025) subjected to thematic analysis.Findings reveal three critical themes: agile principles enabling rapid adaptation through iterative processes and self-organizing teams, network structures facilitating cross-boundary collaboration through decentralized decision-making, and platform ecosystems leveraging digital infrastructure for value co-creation.Literature demonstrates significant gap regarding systematic integration frameworks connecting these complementary models organizations typically adopt piecemeal approaches missing synergistic potential. Research contributes novel Agile-Network-Platform (ANP) Integration Framework proposing three-layer architecture: operational agility (team level),network coordination (organizational level), and platform orchestration (ecosystem level).Organizations should implement parallel transformation addressing team empowerment, structural flattening, and digital platform development creating adaptive organizational systems balancing flexibility, collaboration, and scalability. Study limitations include literature review methodology and emphasis on technology-intensive industries suggesting comparative research across sectors and longitudinal implementations examining ANP framework effectiveness over transformation journeys.

Abstract

This study discusses the implementation and comparative analysis of MPLS VPN Layer 3 on Cisco and Huawei devices using GNS3 simulation in an effort to understand the differences in performance and configuration characteristics of the two network vendors that are widely used in backbone infrastructure. The problem raised is how the configuration, routing stability, and performance of the MPLS VPN L3 service differ when running on devices with different architectures and operating systems. This study aims to provide a comprehensive overview of the structural and operational differences between Cisco IOS and Huawei VRP, including the OSPF routing process, MPLS label exchange, and the formation of VPNv4 BGP. The methods used include simulated topology design, device configuration, parameter testing such as latency, convergence time, throughput, and result analysis using a comparative approach. The results of the study are expected to be able to show the advantages and disadvantages of each vendor in the implementation of MPLS VPN L3 and provide a basis for consideration for practitioners or agencies in choosing network devices that suit operational needs. This research also contributes in the form of configuration documentation and performance analysis that can be a reference for the development of MPLS-based networks in academic and industrial environments.

Abstract

The development of artificial intelligence (AI) technology has presented both opportunities and challenges for intellectual property protection, particularly in the context of digital culture. Generative batik motifs, AI-based ethnic music, and folk tales reproduced through natural language processing are examples of new phenomena that raise legal questions regarding ownership, protection, and the rights of indigenous peoples. This study aims to analyze regulatory gaps in the protection of AI-based traditional cultural expressions (TCE’s) in Indonesia and offer alternative legal models. The research method used is normative juridical with a legislative, conceptual, and comparative approach, supplemented with empirical data in the form of preliminary interviews with cultural practitioners and law enforcement officials. The results of the study show that Indonesian IPR law still focuses on individual creators, is unable to address the issue of non-human creators, and is not accommodative of the communal nature of culture. A sui generis legal protection model is needed that is able to integrate the principles of cultural justice, benefit sharing mechanisms, and digital protection. This article offers ideas for a new regulatory framework that is expected to form the basis for the renewal of national intellectual property law.

Abstract

The rapid development of electronic systems has increased the need for accurate frequency measurement because many electrical and digital devices depend on stable operating frequencies for proper performance. In routine laboratory and field work, digital multimeters are frequently used for frequency checks due to their practicality and availability, yet their readings may be affected by signal conditions and instrument processing limits. This study aims to assemble and evaluate a low-cost digital frequency counter based on the PIC16F628A microcontroller for measuring crystal oscillators and external frequency signals, while benchmarking its readings against a digital multimeter. An experimental quantitative approach was applied that included hardware assembly, schematic reconstruction through PCB trace inspection, block-level functional analysis, and measurement testing using five crystal oscillators and externally generated reference signals derived from a 32.768 kHz source with frequency division. Data were recorded across test points from 1 Hz to 32.768 kHz and summarized through direct comparison between nominal frequencies and instrument readings. The frequency counter produced readings that matched the nominal test frequencies across all external test points within the display resolution limits. Crystal testing also yielded values close to nominal specifications (e.g., 8.0002 MHz for 8 MHz and 11.998 MHz for 12 MHz). The digital multimeter showed small frequency-dependent offsets at higher test points (e.g., 32.770 kHz at 32.768 kHz). These results indicate that the dedicated counter delivers stable measurements across the evaluated range. This work offers a practical reference for electronics education and routine verification by combining schematic reconstruction, reproducible block-level documentation, and empirical validation of a kit-based instrument, providing added value beyond prior studies that emphasize either theory or new system design.

Abstract

This research is motivated by the vulnerability of patients to material losses resulting from Adverse Events Following Immunization (AEFI), in circumstances where no automatic compensation scheme is available. This research aims to analyze hospital liability and legal protection for victims of AEFI. Employing a normative–empirical legal research method (socio-legal research) with statutory, conceptual, and case approaches, this research conducts observations at five healthcare facilities in the Bekasi region and analyzes relevant regulatory frameworks. The first part of the discussion demonstrates that, based on the principle of commutative justice and the doctrine of vicarious liability (Article 1367 of the Indonesian Civil Code), hospitals bear full responsibility for the negligence of their medical personnel; however, empirically, such liability is often reduced to mere administrative procedures. The second part of the discussion identifies defects in preventive legal protection, where healthcare facilities include exoneration clauses (disclaimers of liability) in informed consent forms that violate Article 18 of the Consumer Protection Law, as well as weaknesses in repressive legal protection, which is limited to patient referrals without the assumption of treatment costs. In conclusion, hospitals are obligated to provide restitution in integral, including full coverage of medical treatment costs for victims resulting from procedural errors. The author recommends that hospitals eliminate illegal standard clauses and establish healthcare cost guarantee schemes as a manifestation of product liability and professional responsibility.

Abstract

This study aims to identify the training needs of operational employees at PT Intra Presisi Indonesia through a Training Needs Analysis (TNA) approach that includes organizational analysis, task analysis, and individual analysis. The background of the study is based on the company's training conditions which are still reactive and not yet integrated with long-term human resource development strategies. Data collection was conducted through interviews with management and direct superiors, distribution of questionnaires to operational employees, and review of company documents. The results of the analysis indicate significant competency gaps in the Production, Quality Control, and Maintenance departments. In the Production department, competency gaps were primarily found in the operation of welding robots, die changes, and the application of the 5R principles. In the Quality Control department, the most prominent gaps were in the operation of the Coordinate Measuring Machine (CMM), the application of QC 7 Tools, and root cause analysis. Meanwhile, in the Maintenance department, limited cross-system troubleshooting capabilities and the application of Root Cause Analysis were the main problems. Based on these findings, a training program design was prepared based on competency gap priorities as a basis for developing more targeted, effective, and sustainable training to improve the company's operational performance.

Abstract

This study aims to analyze the effect of income and inflation on household consumption expenditure in 34 provinces in Indonesia. The main issue raised is the fluctuation in household consumption, which does not always move in line with changes in income and inflation, even though these two variables are generally considered to play an important role in determining the level of community welfare. This study uses secondary data obtained from the Central Statistics Agency (BPS) for the period 2016–2024. The method applied is a quantitative approach with panel data regression analysis to see the relationship between variables more comprehensively. The best model was determined through a series of model selection tests, namely the Chow, Hausman, and Lagrange Multiplier tests. Based on the results of these three tests, the Common Effect model was selected as the most appropriate model to describe the relationship between income, inflation, and household consumption. The analysis results show that income and inflation have no significant effect, either partially or simultaneously, on household consumption expenditure. In addition, the low coefficient of determination indicates that most of the variation in consumption is influenced by factors other than those included in this research model. These findings indicate the need for economic policies that focus more on increasing purchasing power and controlling prices in order to maintain the stability of household consumption in Indonesia.
