Abstract:
This research aims to reduce waste in filling hair treatment process in factory. Material usage below 97% will be studied according to guideline from management team. Pareto technique has been applied to classify the value of losses into three categories: 1) Loss from filling BulkPL2 which is cream for producing hair conditioner, 2) Loss from JarPL3 and 3) Inner CapPL3. After analyzing filling process, it found that JarPL3 and Inner CapPL3 are the ingredient of Hair straightening jar product. Consequently, it is concluded that there are 2 difficulties: 1) BulkPL2, bulk loss in hair conditioner production and 2) bulk loss in JarPL3 and Inner CapPL3 are the ingredient of Hair straightening jar product. The new standard in filling weight for PL2 from experimental results are as follows: 1) The level of cream in hopper is at 60% 2) Initial temperature for packing is below 30˚C and 3) Use the real density of each batch to adjust the weight instead of using average density. After applying this new standard in filling process, it can be seen that the loss reduces by 79.65% of loss before improving process which is accounted for 95% MU. The percentage of MU increases by 1.5% MU. The new fill weight standard will be examined to decrease the loss from jar and inner cap. The procedure of new fill weight standard is as follows: 1) Increase frequency of big cleaning to twice a week 2) Increase worker to blow a dust off at Inner Cap before filling 3) Using rubber glove instead of cotton glove and use a new rubber glove everyday 4) Using new box for collecting inner cap instead of using reuse box and 5) Using plastic bag for packing inner cap. After using these new methods in filling process, it can be seen that the loss reduces from 5% to 2.4% per month, which is accounted for 97.6% MU. This is higher than target 97% MU.
