Abstract

VRP is concerned with determining routes for problems involving more than one vehicle with a certain capacity to serve consumers with their respective requests. Route determination is one of the important factors in delivering products to consumers. Determining the optimal distribution route can minimize distance, shorten product delivery time and save transportation costs. PT. XYZ is a company engaged in the distribution of consumer goods. Problems that are happening at PT. XYZ is a product distribution problem where the number of vehicles is limited. The number of customers and the distance from the depot to the customer and from one customer to another is far away. Therefore, it is necessary to determine distribution routes, especially in transportation problems, to save time, distance, and distribution costs. The objectives to be achieved from research at PT. XYZ is to determine the product distribution route using the Sequential Insertion method. Based on the data processing results, the route Sequential Insertion method can serve customers in 5 routes with a total distance of 227.8 km, a total travel time of 15.9 hours, and a total distribution cost of IDR 145,792/week. The travel distance savings are 28.20 km, and the percentage of distribution cost savings is 11%, or the distribution cost savings are IDR 866,304/year. So, the Sequential Insertion method can be applied to determine the optimal distribution route to produce a minimum distribution cost

Abstract

Quality is the overall set of characteristics of a product or service in satisfying part or all of the needs of consumers. Consumers as product users always compare in choosing or using products so this situation results in the role of quality being increasingly important. The problems faced by PT. ABC is the defect rate that occurs in the production of High Strength Steel Plates, namely in January - September 2017 the defect rate of the High Strength Steel Plates type is 3.28%. This of course greatly affects the efforts of PT. ABC to increase production results or at least reduce the level of defects that occur. The purpose of this research is to find out the factors that cause defects, analyze product defects and analyze the causes for continuous improvement. This can be done using the Kaizen method. This technique uses the basic tools of Seven Tools. The results showed that based on data processing using Seven Tools, it can be seen that the number of defects from the type of defect on the steel plate High Strength Steel Plates during 9 months was wavy defects with a percentage of 26.36%, wrong cut with a percentage of 27.61%, not symmetrical with a percentage of 25.62%, and deep scale with a percentage of 20.39%. The results of the analysis that the cause of wrong cutting defects are caused by human factors that are not careful, lack of concentration, and lack of skill. To overcome this problem, Kaizen or 5S analysis was made. Improvements have been made to the production of High Strength Steel Plates for a period of 9 months, from 3.28% to 2.60% there was a decrease in defects or 0.68%.
