Abstract

The Bali Strait is a busy shipping lane with heavy traffic, where external factors such as strong winds and currents often hinder the maneuverability of Ro-Ro vessels like the KMP Trisakti Adinda, interacting with internal factors such as hull fouling. This study aims to identify the internal and external factors hindering maneuverability as well as mitigation efforts. Using a descriptive qualitative approach, the population consisted of the entire crew (22–28 people) on the Ketapang–Gilimanuk route, with a purposive sample of five key informants (Captain, First Mate, Engineer). Instruments included semi-structured interviews, observation, and documentation; analysis followed the Miles–Huberman method (reduction, display, verification). Results indicated that wind (20–30 knots), drift currents, low visibility (<0.5 miles), flat-bottomed hulls vulnerable to side forces, and fouling increased resistance by 5–10%. Conclusion: Effective mitigation through adherence to COLREGs, radar use, routine fouling maintenance, and enhanced safety measures

Abstract

Port watchkeeping is an important activity in ensuring the security and safety of a vessel while it is berthed at the port, as it involves not only technical operational aspects of the ship but also supervision of passengers, luggage, and access to and from the vessel. This study aims to analyze the effectiveness of port watchkeeping implementation on KM. AWU and to identify efforts to improve safety and security while the vessel is in port. The research method used is a qualitative approach with data collection techniques through observation during sea practice, interviews, and documentation, which were then analyzed descriptively. The results show that the implementation of port watchkeeping on KM. AWU has generally been carried out quite effectively, particularly in technical safety aspects such as checking mooring lines and berthing conditions, monitoring vessel stability (draft, trim, and ballast), and inspecting berth lights and signals. However, preventive supervision of passengers and their belongings as well as recording activities in the watchkeeping log book still needs to be improved. In conclusion, the implementation of port watchkeeping has complied with procedural requirements but still requires improvement in preventive supervision aspects. Preventive measures that can be implemented include increasing patrol frequency during busy conditions, conducting active and scheduled CCTV monitoring, tightening supervision of access to and from the vessel, and ensuring that log book records are written in detail and comprehensively.

Abstract

Tuberculosis (TB) is a major health burden in Indonesia, with comorbidity of type 2 diabetes mellitus (DM) further worsening treatment outcomes due to impaired immunity and drug effectiveness. This study aims to analyze the relationship between type 2 DM and TB treatment success at Waled Regional Hospital in Cirebon in 2024. Using a retrospective cross-sectional design based on secondary data from medical records and TB SITB in 104 pulmonary TB patients (total sampling of 507 cases, inclusion: complete records and completed treatment; exclusion: HIV/AIDS or resistant TB), univariate analysis described the demographic distribution, while bivariate analysis applied Fisher's Exact Test (p<0.05). The results showed a significant association (p=0.006), with treatment failure of 17.1% in TB-DM versus 1.6% in TB without DM, and treatment duration >6 months was dominant (70.7%) in TB-DM. Initial characteristics were elderly (46–55 years), housewives, females, elementary school education, and marital status. The study concluded that type 2 diabetes mellitus (DM) reduces TB treatment success through immunological and pharmacokinetic mechanisms; routine DM screening, strict glycemic control, and strengthening DOTS adherence are recommended for the 2030 TB elimination target

Abstract

This study aims to analyze premeditated murder and violent theft against a journalist in Pangkalpinang through the perspective of rational choice theory. The research uses a qualitative method with a case study design. Data were collected through unstructured interviews, field observation, and document review related to the chronology of the case, the relationship between the offender and the victim, the crime location, and post-crime actions. The findings show that the crime was not a spontaneous act, but a sequence of criminal decisions involving motive, access, opportunity, location selection, violence, and efforts to reduce risk after the offense. The work relationship between the offender and the victim became an important factor because it provided social access, information, and an opportunity to approach the victim. The plantation area also increased the opportunity for crime because it had limited social supervision. From the perspective of rational choice theory, the offender is understood as an actor who assessed benefits, risks, and obstacles through bounded rationality. This study offers a theoretical contribution to criminological studies, especially in explaining serious crime through the concept of bounded rationality. Practically, this study highlights the importance of protecting local journalists, strengthening situational awareness, and developing community-based security systems.

Abstract

Indonesia's vast maritime domain demands effective VHF radio communication for safe ship maneuvering amid congested routes, as mandated by SOLAS Chapter IV GMDSS for vessels over 300 GT; Channel 12 supports pilotage coordination on KM. Binaiya, yet technical faults, SOP non-compliance, and traffic density hinder efficacy. This qualitative descriptive study aims to analyze influencing factors and impacts, using Purposive Sampling of 5-10 crew (captain, officers, radio operators), semi-structured interviews, observation sheets, SMCP SOP documentation, and Miles-Huberman analysis (reduction, display, verification). Findings reveal technical issues (noise, corrosion, irregular self-tests), inconsistent SMCP SOP (read-back lapses), and high traffic (eg, 7,000–12,000 ships/week in Makassar) cause overlaps; impacts include reduced clarity, coordination delays, increased collision risks. VHF Channel 12 efficacy is suboptimal; recommend routine training, maintenance, VTS oversight. Future research: quantitative SNR analysis

Abstract

Indonesia ranks second globally in ship-generated marine debris pollution, driven by 32,587 vessels producing unmanaged plastic and food waste that harms ecosystems and human health. This study analyzes MARPOL 73/78 Annex V implementation on MV. Meratus Benoa to identify constraints and recommend improvements. Employing a qualitative case study approach during 12-month sea practice (July 2024–July 2025), the population comprised 20 crew members, with purposive sampling of Chief Officer and Boatswain as key informants. Instruments included observation guidelines, semi-structured interviews, and documents such as Garbage Management Plan; data analysis followed interactive iterative reduction, display, and verification models. Findings reveal principled compliance through waste segregation, Garbage Record Book logging, and supervision, yet suboptimal due to absent incinerator, limited storage, short port stays, and inconsistent crew discipline despite safety meetings enhancing adherence. Conclusions recommend onboard facility upgrades, routine training, and port coordination to achieve 70% plastic pollution reduction targets, informing national maritime sustainability.

Abstract

This study aims to analyze the influence of work motivation and principal leadership on teacher performance through job satisfaction as an intervening variable among private senior high school teachers in Medan Petisah District, Indonesia. This study used a quantitative explanatory approach. The population consisted of 217 educators and education personnel from seven active private senior high schools, and 198 valid responses were obtained through questionnaire distribution. The data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) to examine the measurement model, structural model, direct effects, and indirect effects. The findings show that work motivation does not significantly affect job satisfaction, and principal leadership also does not significantly affect job satisfaction. However, job satisfaction has a positive and significant effect on teacher performance. Work motivation and principal leadership also have positive and significant direct effects on teacher performance. Principal leadership is the strongest predictor of teacher performance, followed by job satisfaction and work motivation. The indirect effects of work motivation and principal leadership on teacher performance through job satisfaction are not significant, indicating that job satisfaction does not mediate these relationships. The study concludes that teacher performance in private senior high schools is influenced more strongly by direct factors, particularly principal leadership, work motivation, and job satisfaction, rather than by an indirect mediation mechanism. This study is limited to private senior high schools in one district and uses cross-sectional self-reported data. This study contributes to educational management literature by showing that job satisfaction functions as a direct predictor of teacher performance, not as an intervening variable in this model.

Abstract

The emergence of Maritime Autonomous Surface Ships (MASS) technology creates normative ambiguity because the current international legal framework is still human-centric. This research departs from the problematic legal ambiguity regarding MASS in the international maritime law regime and how legal certainty theory views and provides solutions to it. This research aims to analyze the unpreparedness of maritime regulations in reaching the operational reality based on artificial intelligence that separates the locus of control from the physical ship, and formulate the direction of legal reform through the perspective of legal certainty theory. The research method used is normative-doctrinal with a statutory and conceptual approach analyzed qualitatively-deductively. The results of the study indicate the urgency of functional redefinition of the role of the captain and the legal status of the ship, as well as a shift in the paradigm of responsibility from the fault-based liability model to strict liability or product liability due to the risk of systemic failure. This has implications for the demand for restructuring of responsibilities from individual-based to system-based to ensure legal predictability and the effectiveness of flag state control.

Abstract

Maritime transportation plays a vital role in supporting global and domestic logistics, but the increasing shipping activity also increases the risk of fire on board. Therefore, early detection systems such as smoke detectors are crucial to support ship safety. This study aims to analyze the working system and maintenance procedures of smoke detectors on KMP Trisna Dwitya. The study used a qualitative descriptive approach with a case study design. The study population included all crew members and the smoke detector system on board, while the sample consisted of First Officers, Second Officers, Helmsmen, and Boatswain selected using purposive sampling. Data collection was conducted through interviews, observation, and documentation, then analyzed using the interactive analysis model of Miles, Huberman, and Saldana through data reduction, data presentation, and conclusion drawing. The results showed that the smoke detector system works automatically through optical sensors connected to the fire alarm panel, thus providing early identification of fire indications. Maintenance is carried out routinely through inspection, cleaning, functional testing, and logbook recording in the Planned Maintenance System. The conclusion of the study shows that the smoke detector on the KMP Trisna Dwitya has functioned effectively as an early fire detection system, although maintenance consistency still needs to be improved to minimize false alarms and maintain system reliability.

Abstract

As a busy shipping route, Indonesia experiences a high number of maritime accidents caused by human factors such as miscommunication and fatigue; therefore, the implementation of Bridge Resource Management (BRM) needs to be evaluated to ensure maritime safety. This study aims to analyze the effectiveness of BRM through responsibility, crew skills, and performance improvement efforts on the bridge of the MV ABM Nubiri. Using a descriptive qualitative approach, the population consisted of the entire bridge crew (17 people), with a purposive sample of three key informants (Captain, Chief Officer, and Helmsman). Research instruments included semi-structured interviews, participant observation, and documentation; analysis was conducted using the Miles-Huberman interactive method with triangulation. Results indicated clear task division, effective communication through repeated commands, and good situational awareness; however, these were hindered by fatigue and low participation from junior crew members. Conclusion: BRM is effective but requires routine training and fatigue management to optimize safety.
