Experience

• Mechanical Product Design - Manual Pellet Machine Politeknik Negeri Bandung · Full-time Jan 2025 – Jul 2026 1 yrs 6 mos Bandung, West Java, Indonesia Designed and developed a manual pellet-making machine using the Pahl and Beitz systematic design methodology as part of a team-based mechanical engineering project.
  
  The project covered the complete product development process, from identifying customer needs to manufacturing and final documentation.
  
  Key responsibilities and activities included:
  
  • Conducted an existing-product study to identify available solutions, limitations, and opportunities for improvement.
  • Gathered information and requirements from potential customers and local MSMEs to understand their needs, problems, and operating conditions.
  • Translated customer needs into a structured requirement list and technical specifications.
  • Developed multiple solution alternatives and evaluated them to determine the most suitable design concept.
  • Created the mechanical design and developed the selected concept into a functional manual pellet machine.
  • Performed engineering calculations for critical components and determined suitable materials and standard components.
  • Evaluated critical components including shafts, bearings, welded joints, and structural components.
  • Prepared detailed CAD models, assembly designs, and engineering drawings.
  • Manufactured the machine by procuring raw materials and standard components, followed by machining processes where required.
  • Participated in machining, fabrication, welding, and assembly of the final prototype.
  • Conducted final assembly and reviewed the functionality of the manufactured machine.
  • Prepared and organized project documentation, including engineering drawings, calculations, design reports, and supporting technical documentation.
  
  This project provided hands-on experience in systematic mechanical design, product development, engineering analysis, CAD modeling, manufacturing, assembly, and technical documentation.
• Mechanical Design & Failure Analysis-Deli Punch Plier Politeknik Negeri Bandung · Full-time Jan 2024 – Jul 2026 2 yrs 6 mos Bandung, West Java, Indonesia Analyzed and evaluated a Deli Punch Plier product as part of a mechanical design project, focusing on its working mechanism, material selection, loading conditions, potential failure modes, and manufacturing processes.
  
  The project included:
  
  • Analyzing the working principle and mechanical mechanism of the punch plier.
  • Identifying the loads and forces acting on critical components during operation.
  • Evaluating the material selection and its suitability for the applied loading conditions.
  • Identifying potential failure modes based on loading, geometry, material properties, and operating conditions.
  • Analyzing the manufacturing processes used to produce the main components.
  • Studying the relationship between product design, material selection, manufacturing processes, and product performance.
  • Using the analysis results to understand possible design improvements and factors affecting product reliability.
  
  This project provided practical experience in mechanical product analysis, failure analysis, material selection, load analysis, and manufacturing process evaluation.
