Waste analysis of fuselage assembly in panelization group of the 117th NC212i aircraft

Dirgantara Indonesia (PTDI) is the single source producer of the NC212i Aircraft. Almost every Aircraft is delivered to the customer over the deadline date. The existence of waste is believed to be one of causing the late delivery. Based on observations of the 117th NC212i Aircraft assembly line, which is precisely at the fuselage assembly in the paneling group, six wastes are identified: waiting, transportation, overprocessing, inventory, and motion. Waste of overproduction does not occur because PTDI applies MTO (Make to Order) system. These 6 wastes are then processed using Waste Assessment Model (WAM). The ranking result is: first place is 25% for defects, second place is 23% for waiting, third place is 17% for motion, fourth place is 15% for inventory, fifth place is 13% for transportation, sixth place is 8% for overprocessing, and seventh place is 0% for overproduction. Three critical wastes based Pareto principle can be minimized, so the delay of aircraft delivery can be reduced

Perancangan Ulang Tata Letak Fasilitas Menggunakan Metode Systematic Layout Planning Pada PT Pilar Kekar Plasindo

Good equipment and product design are meaningless if there is no good layout planning. Problems that are owned by PT. Pilar Kekar Plasindo occurs in the production of small polyethylene. This is because small polyethylene production has large material total transfer distance. Small polyethylene problems, namely the distance between stations, cross-movement, backtracking, and the broken machine that is still placed in the production section. This makes the material handling costs and distances become large. So this research aims to produce a layout design of production facilities that can minimize the distance and cost of material movement. The method used is Systematic Layout Planning (SLP). Three alternative designs were compared, and the second proposed facility layout was chosen because it was able to reduce the total cost of material transfer by 68.3% and reduce the distance of material transfer by 59.6% from the initial facility layout.Peralatan dan desain produk yang baik tidak akan berarti jika tidak terdapat perencanaan tata letak fasilitas yang baik.
