Abstract

One of the efforts to prevent or reduce accidents at work is the use of work safety tools. Fires can occur anywhere, one of which can occur in water transportation equipment, namely ships. Ship accidents caused by fire hazards are very likely to occur. Ships must be detected early to prevent the occurrence of such fires. Therefore, it is necessary to know the use of fire detection equipment in supporting safety on ships. The aim is to prevent fire hazards from spreading and support the ship’s safety, cargo, and, humans. life. This research was carried out on the ship MT Mabrouk. The method used in this research /is a qualitative method that produces descriptive data. Based on the results of research and discussion of problems regarding the fire detection equipment, It was found that there were problems with the ship's lack of coordination with the company and the responsibility of the ship's officers for fire detection equipment that is lacking so that the fire detection device does not function properly. Therefore, the captain must ensure that safety equipment such as tools to start activities to achieve safety from fire hazards is also carried out to control reports made by officers responsible for this equipment. The results of the research and observation can be concluded that shipping companies pay less attention to safety for their crews including ships and their cargo because of a lack of concern for the procurement of safety equipment on board. The author’ is that it is hoped that the participation of shipping companies in supporting the procurement of ship safety equipment for safety at sea.

Abstract

This qualitative study examines the effectiveness of Problem-Based Learning (PBL) models in developing critical thinking and 21st-century skills among middle school students in multicultural classroom environments. Through an interpretive qualitative approach employing in-depth interviews, classroom observations, and focus group discussions, this research explores how PBL methodologies foster active learning and enhance students' analytical capabilities across diverse cultural backgrounds. The study involved 24 middle school teachers and 72 students from three multicultural schools in Indonesia, implementing a purposive sampling strategy. Data analysis utilized Braun and Clarke's reflexive thematic analysis framework to identify patterns and themes related to critical thinking development and cross-cultural learning experiences. Findings reveal that PBL significantly enhances students' critical thinking abilities, promotes collaborative problem-solving skills, and facilitates meaningful cross-cultural interactions. The research demonstrates that multicultural PBL environments create authentic learning opportunities where students develop both cognitive and social competencies essential for 21st-century success. However, implementation challenges include teacher preparation requirements, resource limitations, and the need for culturally responsive instructional materials. The study concludes that well-structured PBL approaches in multicultural settings effectively prepare middle school students for complex problem-solving while fostering intercultural understanding and communication skills. These findings contribute to educational scholarship by providing evidence-based insights into the integration of active learning methodologies with multicultural education frameworks

Abstract

AHTS vessels are tasked with performing heavy-duty operations such as towing and deploying anchors, which are critical steps in the installation and relocation of platforms at designated locations. The Dynamic Positioning System (DPS) consists of several separate modules, each performing its specific function, and collectively counteracting environmental disturbances such as wind, currents, and waves. The operation of the dynamic positioning system is carried out by the captain, assisted by ship officers who hold DPO certification. As the DP system operator, the DPO is responsible for monitoring, evaluating, and controlling the performance of the DP system to ensure the vessel remains stable and in the correct position during operations in waters with adverse weather conditions. This study was conducted to investigate Dynamic Positioning (DP) on the AHTS vessel OPS AORA, which was operating suboptimally. The adverse weather conditions caused the vessel to lose its position. This incident disrupted the vessel's operations during DP operations at the Borr Thor offshore rig in the Bukit Tua Field of Petronas. The study was conducted using a qualitative case study approach. The impact of adverse weather conditions on the Dynamic Positioning (DP) system in the context of offshore AHTS vessel operations was explored through interviews with experienced masters and officers. The research findings revealed that sensor and navigation malfunctions, reduced thruster efficiency, and decreased vessel stability caused the DP system to lose accuracy, potentially leading to position failure and increased accident risks. The implementation of technical and procedural mitigation strategies, such as sensor redundancy, real-time monitoring of sea conditions, and enhancing operator competence, can effectively control the negative impacts of adverse weather conditions.
