RANCANG BANGUN ALAT BANTU PERAKITAN DAN PENGELASAN KURSI LABORATORIUM (LAB STOOL)
2018
The quality of mass produced lab stools are determined based on the similarity of shape and size of the labs stools produced. Assembly work is done by two technicians for 55 minutes without using assembly tools (Fixture). Based on this data, it can be inferred that in terms of working time assembly process is considered too long or inefficient in terms of time. Based on the amount of labor it is still not efficient or the productivity is still low, so there must be innovations made to speed up the assembly time. in addition to low productivity, without assembly tools and welding the product is not similiar because there is a change of shape after welding process. It means the quality of the product is not good. Business competition in the field of metal furniture manufacture is growing so that producers have to think of methods to improve productivity, quality and speed up production time. To increase productivity, it is necessary to assemble and fix the parts to be assembled to eliminate unwanted movement due to the welding distortion. The use of fixtures in the assembly process can be done by one person with an average processing time of 25 minutes.
