Abstract

Due to conventional thai rice noodles production has long time in producing, results low production

capacity. This is not enough to market demand which over than 400 kg per day. The conventional

process has 13 steps and take 3 hours and a half per process time. One process time can produce 30 kg of thai rice noodles then every 1 hour can produce 360 kg. Thus, 11 hour of the period of production

time can produce 360 kg of thai rice noodles which is not correspond to demand. This research aims to increase productivity of thai rice noodles producing process via work study. From research, time study,

motion study, process analysis and new process design were used. From study, the production process

was reduced to 8 steps. The period of production time per one process is 2 hours and 40 minutes that

can produce 30 kg of thai rice noodles. After that, every 25 minutes can produce 30 kg of thai rice noodles. Moreover, 11 hours of period of production time in one day can produce 700 kg of noodles.

After improvement, it was found that the thai rice noodles production are increase to 99.44%. From the

production improvement, it helps in plant layout adjust which be in line with work in suction. And results in the distance of motion in 30 kg thai rice noodles production from 137.80 meters to 94.20 meters

corresponding to 31.68%.
