Experience

  • Production Engineering Intern at PT Kereta Api Indonesia (Persero)
    Sep 2025 - Nov 2025 · 3 mos

    Internship Experience – PT Kereta Api Indonesia (Persero) UPT Balai Yasa Manggarai – Metal Workshop (Losd Logam) Activities and Responsibilities : 1. Operated lathe machines, drilling machines, and shaping machines to manufacture and repair railway components such as Bush Boffer, Pen Koneng, Pin Swivel, and Pen Penonjok Boffer. Tasks included drilling holes, reducing diameters, threading, chamfering, and measuring components to ensure accuracy and compliance with specifications. 2. Performed cutting processes on various steel materials including round bars, pins, dummy couplings, bogie supports, and other mechanical parts using mechanical saws, shaping machines, and oxy cutting techniques while following work instructions and tolerances. Conducted SMAW welding on components such as spring planks, train doors, TRL safety brackets, and workshop tools. Learned to select proper welding current, electrodes, and welding positions in accordance with standard welding practices. 3. Assisted in Magnetic Particle Testing (MPT) to detect cracks on Boffer components using Yoke, Magnavis, and WCP, including identifying allowable defect limits and understanding different types of cracks. 4. Operated hydraulic press machines to form galvanized steel plates for train doors, ensuring correct pressure settings and material thickness. 5. Used laser cutting machines to produce components such as air brake hose holders, handle spring protectors, and stop chocks. Learned basic design setup, arraying parts, and adjusting cutting parameters such as oxygen pressure and cutting speed. 6. Fabricated and repaired workshop tools, including workpiece clamping jaws and welding tables, involving cutting, assembling, and welding processes. 7. Gained hands-on understanding of bogie components and braking systems, including spring planks, bolsters, dampers, side bearers, primary and secondary springs, and air brake mechanisms.

  • Aircraft Maintenance Technician at GMF AeroAsia
    Jul 2025 - Sep 2025 · 3 mos

    During my internship at PT GMF AeroAsia, I had the opportunity to be directly involved in various line and base maintenance activities for commercial aircraft (ATR 72-600, Boeing 737NG, Boeing 777, Airbus A320 & A330). My responsibilities and learning experiences included : 1. Performing inspection and maintenance of aircraft components, such as replacing spark plugs, seals, filters, and checking the fuel system, hydraulic system, and lubrication system. 2. Supporting troubleshooting tasks on aircraft systems, including propeller vibration analysis, brake system checks, and handling debris findings in oil/engine components. 3. Observing and participating in engine maintenance procedures, including flushing, chemical cleaning, borescope inspections, engine removal & installation, and performance testing in the test cell. 4. Gaining exposure to both scheduled and unscheduled maintenance (A-Check to D-Check), while learning to read and apply technical documentation such as AMM (Aircraft Maintenance Manual), MP (Maintenance Program), MSAO, and MDR. 5. Assisting in inspection and rectification activities on avionics, pneumatic, environmental control systems, as well as landing gear and brake systems. 6. Expanding knowledge of safety systems and emergency equipment (ELT, fire extinguisher bottles, black box, survival kits), as well as avionics update procedures (Navigation Database & Avionic Suite Software). This internship provided me with a comprehensive understanding of aircraft maintenance practices, aviation safety standards, and teamwork coordination within hangar and workshop environments, which strengthened my foundation in aviation engineering and aircraft maintenance.
