Quality is a benchmark to determine the level of good and bad of a product. The level of quality of a product will affect customer satisfaction, hence, to produce high quality products, it is necessary for a company to have a quality control process. Quality control is a process that aims to maintain the quality of products and services that have been promised to consumers. In this study, quality control is carried out in the sugar packaging process. Where in the sugar packaging process found the resulting product has a poor quality, defective and not in accordance with specifications. This study uses the Statistical Process Control (SPC) method which aims to determine the causes of defective products with the intention that the packaging process can further minimize the level of product defects. The SPC method is a statistical analysis technique with seven statistical tools or seven tools. Based on the results of the study it can be seen that the cause of product damage / defects in the product packaging process is caused by three types of damage namely damage due to conveyor (38.17%), damage due to machine pinched (35.82%), and damage due to loose seams (26,00%) This type of damage can be caused by human error and other factors such as engine condition, engine cleanliness and the monitoring process. Proposed improvements recommended for the company are to provide training to employees, make clear work instructions, conduct periodic maintenance for the machines used, supervise all work areas, and carry out quality control for every acceptance of raw materials.

PT. X is a distributor of beverage companies that produces various soft drinks (soft drinks). The problem that occurs in these distributors is that they have to service many shops located far from warehouses, with locations scattered in several places and limited transportation facilities with an average capacity of 150 boxes / car. The average number of stores that must be visited every day is 40 for one distribution area. Planning the sequence of product distribution to consumers is still based on subjective decisions from the driver and kernet, so the product distribution time is less than the maximum. This research will design a product delivery route applying the Traveling Salesman Problem (TSP) model to optimize the distribution route. This research uses store sorting method namely Nearest Neighbor and Branch and Bound methods with the help of WinQSB software so that the best product delivery route is obtained. These results can be seen with more optimal mileage, travel time and costs. Based on data processing, it was found that the best X product delivery route at the distributor of PT X Bukittingi was obtained using the Branch and Bound store ordering method.
