Quality Assurance System Enhancement in The Manufacturing of Grass Jelly Water

Abstract

Grass jelly water is a healthy beverage that manufacturers take into account about quality. The purpose of this research is to enhance the effectiveness of the quality assurance system in the production of grass jelly water bottles without deterioration before the expiry date and with the exact weight specified on the label. Quality assurance approach composed of three steps 1) quality planning by identifying the quality dimensions and applying quality function deployment to obtain specifications for the process, 2) quality control in the production by using fish-bone diagram considering control points in the manufacturing process of grass jelly water compared to the target value, and 3) quality audit. The results showed that there are 16 specifications to be controlled, but there are four control points to increase for setting the actions as follows: the raw material preparation process has to be controlled the separation of raw materials in both dry and wet, the filling process has to be improved the grass jelly water nozzles and set the maintenance method for the foil sealing machine in order to control the volume of grass jelly water and leakage, and the packaging and storage process has to be determined the work instruction to prevent the broken bottles. Whenever the above processes are implemented, grass jelly water bottles are more consistent with the quality requirements.
