In 2017, BMW Group Indonesia (BGI) announced the highest achievement by a massive <br /> <br /> increase of BMW sales. In the first quarter of 2018, there was also an increase in BMW sales <br /> <br /> compared to the same period in 2017. Of these two achievements, the BMW X1 is the main <br /> <br /> product that has the biggest sales increase so that BGI predicts an increase in demand for BMW <br /> <br /> X1 in the future. <br /> <br /> This successful attainment was achieved by BGI by cooperating with PT Gaya Motor, a <br /> <br /> company who engaged in the assembly of four-wheeled vehicles, such as BMW, with the <br /> <br /> production process based completely knocked down. To anticipate the increasing demand, the <br /> <br /> company evaluates one common takt time method which is no longer relevant and results in a <br /> <br /> low productivity assembly line, especially in the overhead line. <br /> <br /> Low productivity was solved through the newly proposed assembly line design using the lean <br /> <br /> manufacturing approach, such as waste elimination, line balancing using ranked positional <br /> <br /> weight and largest candidate rule method, process activity mapping, workgroup process <br /> <br /> mapping, layout evaluation using spaghetti diagrams, and 5S. <br /> <br /> It is known that excess motion is the highest type of waste with a proportion of 43.50%. The <br /> <br /> solution provided was proven to increase productivity by decreasing idle time by 1545.74 <br /> <br /> seconds and smoothness index by 850.73, increasing line efficiency by 15.30% and production <br /> <br /> capacity from 12 to 16 units per day, as well as a more optimal layout proposal.
