Abstract

This study examines practical efforts to increase Boil-Off Gas (BOG) production without relying on the Fuel Gas Pump (FGP) during ballast voyage on the M.T. Coral Energy. In this condition, the vessel carries only a small amount of heel cargo, causing limited natural evaporation and a significant drop in tank pressure, which often results in insufficient BOG supply for the main engine. These operational constraints highlight the need for an alternative strategy that is both efficient and safer for cryogenic equipment.Using a qualitative descriptive approach, the research incorporates direct observation, structured interviews with deck officers, and operational documentation from the vessel. Data were analyzed using a fishbone framework to trace the root causes of low BOG production, focusing on technical, environmental, and human-factor aspects. The findings show that applying the top spray method using the deepwell pump effectively increases tank pressure and stabilizes BOG availability during ballast voyage. This method helps maintain a consistent gas supply for propulsion without adding mechanical load or maintenance risks to the FGP. The success of this approach depends largely on accurate flow control, careful pressure monitoring, and the crew’s understanding of the operational procedure. Overall, the study concludes that top spray is a reliable and energy-efficient alternative for BOG management when FGP use is minimized. The results are expected to support LNG carrier operations, particularly in optimizing fuel systems under low-cargo condition.

Abstract

LNG cargo tanks are specifically designed to transport liquefied gas, and the coolingdown process becomes a critical stage prior to loading. This process is performed by spraying liquid gas through spray nozzles installed on the tank dome. This study employs a descriptive qualitative method, with data collected through observation, interviews, and documentation. The data were analyzed using the Miles and Huberman model, which consist of data condensation, data display, and conclusion drawing. The findings indicate that the coolingdown process on LNG/C Pan Africa generally complies with SIGTTO and IGC Code standards. However, two major issues were identified: a leakage in the cooldown valve on loading line number 2 caused by corrosion, which reduced the cooling rate from the standard 20°C/hour to approximately 10°C/hour, and a 1.5 hour delay in operating nitrogen system, which resulted in the IBS pressure not reaching the required 0.2-0.4 kPa. The study concludes that optimization of the coolingdown process can be achieved through preventive maintenance of the cooldown valve, improved coordination among officers, and enchanced accuracy in monitoring temperature and pressure. These recommendations are expected to improve the efficiency and safety pf LNG loading operations.
Strategy To Increase The Competitiveness Of Indonesian Processed Food Products To Thailand Through The Role Of Human Resources Competence: Analysis Of Revealed Comparative Advantage (RCA) And Dynamic Export Competitiveness Index (ECI) Hidayatulloh, Yasykur; Yustiana, Dewi; Uripan , Koen Irianto; Sutoyo; Sutomo

Abstract

This research aims to formulate a strategy to increase the competitiveness of Indonesian food and beverage products in the Thai market through the role of human resource (HR) competencies and participation in international exhibitions. The research approach used is mixed-method, which combines qualitative and quantitative analysis. Qualitative data were collected through in-depth interviews with exporters and related stakeholders, while quantitative data were analyzed using the Partial Least Squares Structural Equation Modeling (PLS-SEM) method. In addition, product competitiveness is evaluated through the Revealed Comparative Advantage (RCA) approach and the Dynamic Export Competitiveness Index (ECI) dynamically for the period 2021–2024. The results of the study show that human resource competence has a significant effect on increasing export competitiveness, with a t-statistic value of 5.949 and a p-value of 0.000. The role of international exhibitions has also been proven to indirectly contribute to increasing competitiveness through improving human resource competence. RCA and ECI analysis showed positive trends in several superior products such as processed fish, sauces and spices, as well as margarine and fat mixtures. These findings reinforce the importance of human resource development strategies and the use of international exhibitions as a means of market penetration. This study recommends that governments, stakeholders, and business actors be able to strengthen export-oriented HR training programs and encourage active participation in curated international exhibitions. This research also opens up further study space regarding the integration of digitalization aspects in the promotion of Indonesia's superior products to the global market.

Abstract

Work safety is a critical priority in maritime operations, particularly within the high-risk environment of tanker vessels. In accordance with International Maritime Organization (IMO) regulations, hazard reporting constitutes a fundamental pillar of the Safety Management System (SMS), designed to mitigate risks and foster a proactive safety culture. This study investigates the effectiveness of Hazard Report implementation on the MT. Al Daayen, specifically analyzing its impact on accident prevention behaviors and identifying the obstacles impeding consistent crew participation. Adopting a qualitative descriptive approach, this research utilizes Miles and Huberman’s interactive model to analyze data gathered through structured interviews, direct field observations, and longitudinal documentation reviews. The results demonstrate that the system has significantly enhanced safety culture, evidenced by heightened crew vigilance, consistent PPE adherence, and a measurable decline in near-miss incidents between 2021 and 2024. However, the study reveals that implementation remains suboptimal due to low participation from ratings. The analysis isolates critical barriers: human factors, including a lack of confidence and psychological fears of assigning blame; methodological constraints caused by lengthy, impractical forms; and environmental pressures, where the fast-paced operational tempo compels crew members to prioritize immediate rectification over formal documentation. The study concludes that simplifying reporting mechanisms is essential for ensuring inclusive safety engagement.

Abstract

This study aims to determine the role of Pancasila Education in shaping civic responsibility and multicultural awareness of students, especially in grade X. This study is motivated by the importance of strengthening civic character and tolerance amidst the diversity of Indonesian society. This research uses a qualitative approach with a descriptive qualitative research type. Data were obtained from primary and secondary sources through observation, interview, and documentation techniques. Data validity was tested through source triangulation and technical triangulation. Data analysis was carried out through the stages of data collection, data reduction, data presentation, and drawing conclusions. The results of the study show that Pancasila Education plays a significant role in shaping students' attitudes of responsibility as demonstrated through understanding of rights and obligations, discipline, compliance with rules and participation in school activities. Pancasila Education also contributes to fostering students' multicultural awareness, this is reflected in students' attitudes that respect differences and are able to work together in diverse environments. Pancasila Education teachers not only have a role as teachers but also play a strategic role as motivators, facilitators, and role models for students.
