ABSTRACT
A project titled ‘Lead Time Improvement by Re-Layout in Aerospace Company’ has been carried out at CTRM Aero Composite Sdn. Bhd in Batu Berendam, Malacca. The objectives of this project are mainly to enhance the process layout efficiency of the Painting Department and improve its productivity with the aim of creating a smoother product flow and utilizing the space within the production area. There are some significant problems faced by the company such as improper product flow and poor departments’ arrangement. The existing current layout is used as the basis of developing the new layout. Relevant information such as product flow, space requirement and process flow are gathered and as initial step seeking for the further solutions. In addition, Stopwatch Time Study Method has been used in order to identify the cycle time of the product in Painting Department. The overall manpower per process and the takt time of the product also being collected in order to make an improvement to the current layout. The analysis using Process Analysis Technique has been used to look up for an efficiency process flow. The comparison Pre Improvement and Post Improvement Measurement have been analyzed using Pareto Chart. In addition, the re-layout activity was also considering for having a better workplace in term of safety and ergonomic issue. And last but not least, the suggestion to enhance the process flow, increase the productivity and improve the workplace in the Painting Department had been done.

ABSTRAK
Kajian yang bertajuk ‘Lead Time Improvement by Re-layout in Aerospace Company’ telah pun dilaksanakan di CTRM Aero Composite Sdn Bhd di Batu Berendam, Melaka. Objektif bagi pelaksanaan projek ini pada amnya adalah untuk membaik pulih keberkesanan susunatur operasi yang terdapat di ‘Painting Department’ dan meningkatkan produktiviti dengan tujuan untuk melicinkan pengaliran produk serta memaksimakan tahap penggunaan ruang kilang tersebut. Masalah yang paling ketara bagi kilang tersebut ialah pengaliran produk yang tidak sempurna dan susunatur jabatan yang tidak baik dan efektif. Susunatur kilang yang sedia ada telah dijadikan sebagai rujukan kepada rekabentuk dan perancangan alternatif yang baru. Maklumat yang berkaitan pengaliran produk, keperluan ruang dan pengaliran proses untuk menghasilkan produk yang siap dikumpul dan sebagai langkah awal bagi perancangan susunatur yang baru. Dalam pada itu, kaedah ‘Stopwatch Time Study’ telah dilakukan bagi mendapatkan maklumat mengenai masa bagi sesuatu porduk yang telah siap. Keseluruhan penggunaan pekerja pada sesuatu proses juga dikenalpasti untuk tujuan meningkatkan susunatur yang baru lebih efektif dan berkesan. Kemudian, kaedah Proses Analisis digunakan untuk mendapatkan aliran proses yang efektif. Perbezaan sebelum dan selepas proses pegubahsuaian akan dianalisa meggunakan Carta Pareto. Akhirnya, cadangan ke arah membaik pulih aliran proses, peningkatan produktif serta penggunaan ruang kerja yang berkesan di dalam kilang akan dilaksanakan.
