Abstract

The injector is a component that functions to atomize fuel in the combustion process, the performance of this injector is very influential on whether or not the combustion process is complete in a diesel generator. The combustion process is very important so that the diesel generator gets optimal performance so that it can properly supply the electricity needs on board. The research method used is descriptive qualitative using data analysis techniques using fishbone diagrams and using data collection techniques through interviews, observation and documentation studies. The indications that appear about the not optimal fogging is the high temperature of the exhaust gas, the exhaust gas is black in color and detonation appears. After analysis, several causes were found, one of which was a lack of pressure on the injector.

Abstract

This research investigates the repercussions of crew change practices on contractual adherence within the maritime industry, focusing on PT. Amas Iscindo Utama. Through a mixed-methods approach, quantitative data was collected via structured questionnaires and analyzed using SPSS, supplemented by qualitative insights derived from open-ended responses. Findings reveal that delayed crew recruitment significantly impacts contractual accuracy and compliance, leading to operational disruptions and challenges in crew management. Recruitment challenges, contractual inconsistencies, operational disruptions, and professionalism and standards emerged as key themes, underscoring the multifaceted nature of crew management dynamics. Strategic recommendations include streamlining recruitment processes, developing standardized contractual templates, fostering transparent communication channels, prioritizing professional development initiatives, and safeguarding crew welfare and rights. Collaboration among industry stakeholders is essential to implement proactive measures and uphold professionalism and adherence to contractual obligations within the maritime sector. This research contributes to advancing knowledge and best practices in crew management and contractual governance, informing policy decisions and interventions to enhance the sustainability and competitiveness of the maritime industry.
