Abstract

The Safety Management System has 4 pillars, one of the pillars of the safety management system is Safety Assurance. The implementation of a good Safety Management System can affect the level of technician's workplace safety, it is necessary to measure each pillar of the Safety Management System. The pillar of Safety Assurance is something that needs to be measured at PT.XYZ. This study aims to assess safety assurance and improve work safety. The method used in this research is quantitative with descriptive and verification techniques. The data obtained came from questionnaires, observations, documentation, and interviews. The population used as research samples taken are all technicians who work with as many as 36 people in Hangar Hall E PT.XYZ. This study's results indicate a positive effect of 30% between safety assurance and work safety.

Abstract

This study aims to analyze the strength of the propeller on an unmanned aerial vehicle (UAV) using additive manufacturing method with Stereolithography (SLA). In this study, testing was conducted by examining the tensile and bending strength of the propeller using a Universal Testing Machine. The results showed that the structural strength of the propeller made of Tan resin applied to the propeller with a 100% infill percentage configuration was better than other 50% infill percentage configurations. The highest tensile strength result was obtained with 100% infill at a value of 133.8 MPa, while the highest bending strength result was also obtained with 100% infill at a value of 2.76 MPa. This research provides an important contribution to the development of additive manufacturing technology in the manufacturing industry, particularly in the production of propellers for UAVs with optimal strength.

Abstract

Penelitian ini bertujuan untuk menganalisis kekuatan propeller pada pesawat tanpa awak dengan menggunakan metode additive manufacturing yang menggunakan Stereolithography (SLA). Dalam penelitian ini, pengujian dilakukan dengan menguji kekuatan tensile dan bending pada propeller menggunakan Universal Testing Machine. Hasil pengujian menunjukkan bahwa kekuatan struktur pada propeller berbahan resin Tan yang diaplikasikan pada propeller dengan konfigurasi persentase infill 100% lebih baik dibandingkan dengan konfigurasi infill 50% lainnya. Hasil kekuatan tensile tertinggi diperoleh pada infill 100% dengan nilai sebesar 133,8 MPa, sedangkan hasil kekuatan bending tertinggi juga diperoleh pada infill 100% dengan nilai sebesar 2,76 MPa. Penelitian ini memberikan kontribusi penting dalam pengembangan teknologi additive manufacturing dalam industri manufaktur, khususnya pada pembuatan propeller pesawat tanpa awak dengan kekuatan yang optimal.

Abstract

One of the fire extinguishers commonly used in various places and also utilized in practical training for students in the Aircraft Accident Rescue Program (Diploma Three) is the Portable Fire Extinguisher (APAR). In their learning, students are not only taught how to use APAR but also about its working system, maintenance, and refilling process. A drawback of the current APAR refilling process is the frequent spillage of dry chemical powder (DCP) and inaccurate measurements. The aim of this research is to design an automatic APAR refilling device that can serve as a learning tool for students. The method used is VDI 2221 (Verein Deutscher Ingenieure), a systematic approach for solving problems and optimizing the use of materials and technology. The outcome of this research is the development of a comprehensive APAR refilling device that integrates the removal of old DCP, refilling with new DCP, and nitrogen charging. The test results showed that the process of suctioning DCP powder and filling nitrogen for a 6 kg cylinder takes 7 minutes and 50 seconds. This tool makes the APAR refilling process easier, minimizes DCP spillage, and saves time during the refilling process.

Abstract

The aim of this study is to design a digitally based Student Record and Practical Project Record application that complies with CASR Part 147 and EASA Part 147 standards. This application is expected to overcome various weaknesses of the manual system in recording learning hours, practicals and assessment, such as the risk of document damage, low efficiency and limited data accuracy. The research methodology adopts a systematic approach based on VDI 2222, which includes five main stages: needs analysis, system conceptualisation, technical design, prototype implementation and evaluation of results. The application was implemented using the Laravel framework, cloud-based technology and a responsively designed user interface to ensure data security, ease of access and operational efficiency. Application testing involved the main users, namely learners, teachers and administrators, to evaluate the functionality and performance of the system. The results show that the application is able to record learning and practical hours in accordance with the regulations (3,000 hours for CASR and 2,400 hours for EASA), provide comprehensive assessment reports and facilitate efficient management of practical documents. Therefore, this application has proven to be effective in supporting the management of vocational aviation training and has the potential to become a model for the development of similar systems in other educational institutions. For wider implementation, user training and system optimisation are required to ensure sustainability and adaptability.

Abstract

This study aims to analyze the failure of the Weather Radar System using amixed-methods sequential explanatory approach. Flight safety is highly dependent on thereliability of avionics systems, one of which is the Weather Radar System that functions todetect extreme weather phenomena. Damage to this system is categorized as a no-go itemin the MEL and based on data from the Top Delay Report of PT GMF Aero Asia Tbk for theperiod 2020–2024, it ranks fifth as the highest cause of delays on the Airbus A320-200, with341 failure reports. The quantitative stage uses Failure Mode and Effects Analysis (FMEA)and Pareto Diagrams to identify critical components, while the qualitative stage uses RootCause Analysis (RCA) and Fishbone Diagrams to explore the root causes of failure. Theresults show that the Transceiver is the most problematic component with 39% ofunscheduled removals with the dominant failure mode being Intermittent Signal with an RPNvalue of 336. RCA reveals the main causal factors including human error, non-compliancewith procedures, limited tools, low material quality, and exposure to extreme environments.Recommendations for improvement include improving technician competency, toolprocurement and calibration, stringent material vendor selection, and system protection fromextreme weather. This research is expected to support increased maintenance effectiveness,reduce delays, and strengthen the safety culture at GMF.
