Abstract

An engine bleed trip is an indication that there is a failure in the engine bleed system in regulating the temperature and pressure of the bleed air. This can affect the work of other systems that rely on the output of the engine bleed system, one of which is the cabin pressure system. The aim of this research is to find out the percentage level of the need for main components in the engine bleed system to be replaced in handling engine bleed trip cases. This research is an ex post-facto comparative research with primary data collection methods sourced from aircraft maintenance databases and interviews. The research results showed that from a total of 52 bleed trip cases that occurred during 17 months, the percentage of main components that needed to be replaced were the 390F thermostat sensor (42.3%), precooler control valve (19.2%), pressure regulating shuttle valve (11 .5%), bleed air regulator (7.7%), and the rest are other components.

Abstract

Criminal acts in the community such as theft of motorized vehicles, bicycles and hit-and-run victims are increasingly widespread, in the last 1 year in Fanindo housing there have been four thefts of children's bicycles. Therefore, a security system is needed in the housing to prevent and monitor things that harm the community, namely in the form of CCTV. The methods carried out in the service include surveying the location to determine the strategic installation point with the local RT head, selecting the type of camera, determining the electrical path, determining the placement of the DVR (Digital Video Recorder), and software settings. This service activity received a very positive response from both the RT management and the local community and is expected to be able to reduce criminal acts such as theft and other criminal acts.

Abstract

The Boeing 737-900 ER aircraft has a system called landing gear indication which in its application uses a proximity sensor that is useful in providing information about the position of the landing gear. However, this system can experience problems where if the landing gear indication does not function, the pilot cannot obtain information from the instrument that ensures the position of the landing gear. The purpose of this study is to identify problems that often occur in the landing gear indication system on the aircraft. The analysis was carried out using the Root Cause Analysis (RCA) method with the Fishbone Diagram approach. From the identification results, it was found that the main cause was a problem with the proximity switch sensor experiencing corrosion and changes in position which caused the signal reading to be inaccurate. For this reason, it is necessary to replace components and adjust the sensor position so that the system can run properly.

Abstract

The maritime industry generally recruits vocational graduates who possess specific skills, such as technical drawing and proficiency in Computer-Aided Design software. However, some vocational high school students still have limitations in industry-based drafter practice and the use of CAD software. This community service activity aims to improve the basic competencies of vocational high school students as ship construction technical drafters through structured CAD training. The activity was held at Politeknik Negeri Batam on 7–10 October 2025, involving 26 participants from SMKS Kartini Batam and SMKS Al Jabar Batam, consisting of students and accompanying teachers. The implementation methods included theoretical instruction, demonstrations, hands-on practice, simple industry-based case studies, and intensive mentoring. The training materials covered an introduction to ship construction, basic CAD usage, basic object creation, dynamic input, editing tools, orthographic drawing, dimensioning, templates, plotting, and an introduction to three-dimensional CAD. Evaluation was conducted through a pre-test, post-test, and participant satisfaction questionnaire. The results showed an improvement in participants’ understanding and basic skills in the field of ship construction drafting. Based on the questionnaire results, 95.8% of participants strongly agreed that the training materials were useful, 87.5% strongly agreed that the materials were relevant to their needs, and 87.5% strongly agreed that their knowledge and skills improved after participating in the training. Therefore, this training was effective in strengthening basic CAD-based drafting competencies and supporting vocational high school students’ readiness to meet the needs of the maritime industry.

Abstract

Fuel leaks in aircraft engines are a critical maintenance issue that can compromise flight safety and increase operating costs. This study aims to analyze the causes and resolve a specific case of a fuel leak classified as a stain (wet area diameter less than ¾ inch) on the fuel drains tank ejector area of the right engine (Engine 2) of an Airbus A330-300 PK-GHC aircraft. The methodology employed includes visual field observations and a review of technical documents based on Aircraft Maintenance Manual (AMM) 71-71-00-200-802-A and Troubleshooting Manual (TSM) task card 71-71-42-000-804-A. The investigation results showed that the leak was caused by structural damage to the left input connector. Corrective action was successfully executed by replacing the connector and installing a new seal ring (Part Number AS43013-131), followed by tightening the bolts to a torque specification of 90–110 lbf.in and the connector to 193.5–236.5 lbf.in. A post installation visual check confirmed that the system returned to normal operation with zero subsequent leaks. This case study provides a practical contribution by establishing that the connector on the fuel drains tank ejector is a critical component requiring regular preventive inspections, serving as a technical reference to prevent similar potential leak risks on wide-body aircraft fleets.
