PT. X is a company domiciled in Gedebage, Bandung which is engaged in the manufacturing industry by producing precision parts using CNC machines. PT. X is a sub-contracting company that usually serves project work from other companies. PT. Y and PT. Z is a regular customer who often works with PT. X. So that PT. X often sends finished products directly to PT. Y who is domiciled on Jl. Gatot Subroto, Bandung and also PT. Z who is domiciled on Jl. Pajajaran, Bandung. To minimize the cost of distribution of goods, PT. X must determine an adequate path taking into account the optimization of transportation costs. One of the variables that affect transportation costs is distance. It is assumed that the optimal path for transportation costs is the shortest distance using the Dijkstra method. This test uses data from Google Maps to find out the distance to each destination, making it easier to get the shortest path. Obtained the shortest path from PT. X to PT.Y is 12.3 Km via West Java Police then Carefour, while the shortest route is from PT. Y to PT. Z is 10.7 Km via Simpang Lima then Vie Hotel Westhoff. So that the optimal total mileage for distributing goods is 23 Km.

Distribution of goods from producers to the hands of consumers becomes one aspect in running a business that must be planned and taken into account in order to meet the needs of the market. Delivery of goods results in costs incurred and is one of the obstacles that are often faced. Problems in the distribution of goods include the amount of inventory, the amount of consumer demand, the distance traveled and the costs that come out during the delivery process. This study describes taking into account optimal postage with transportation methods to generate maximum efficiency costs. The problem faced in this case using the North West Corner (NWC) method, then the results of the data obtained were tested optimized using LINGO software. Before the research was conducted, the cost of postage incurred by the company is Rp.278.000. The results of the research obtained after applying the NWC is Rp.255.000 and LINGO software method is Rp.240.000. The purpose of this research is to get optimal costs on the distribution of chicken eggs to increase cost savings at Ayam Sehat.com Shop in Cimahi.

PT XYZ is a private company engaged in steel manufacturing, one of the products produced by this company is tire cord. This product is in the form of steel wire that serves to maintain the shape of the tire. The length of the wire is a very critical factor in quality, because one coil of wire that is not suitable length will cause a lot of scrap in consumers, namely the company that produces tires and of course this will cause customer complaints and customer dissatisfaction. Therefore, it is contained in the Automatic Length Control system to avoid the possibility of wire coils that are not suitable for delivery to customers. Every system must have weaknesses that lead to failure that causes maintenance breakdown. This study used the DMADV method to reduce breakdown maintenance on the Automatic Length Control system at PT XYZ. After going through all the stages using the DMADV method (Define, Measure, Analyze, Design, and Verify) a significant reduction in the number of breakdowns was obtained. Reduction of ALC-related breakdown maintenance by 88.1% or from 185 breakdowns to only 22 breakdowns. So that this flat pulley design was successful in reducing alc problems in henxing machines that produce tyre cord construction 3 +9 +15x0,23 +0.15 NT 6/12/18/5 SSZS
