Abstract

PT XYZ is one of the flexible manufacturing industries. In terms of overcoming competition in the printing industry, PT XYZ built the Rotogravure company in 2011. The subsidiary is engaged in manufacturing Cylinder Rotogravure which supplies PT XYZ units. From a few years back since the establishment of this company, the target that should have been reached in amount of 5760 Cylinder / year. This target hasnot been achieved. This occurs because there is a problem in the production process reaching ± 49.4% and continues to appear which results in a disrupted delivery schedule, many customer complaints due to the low quality goods being shipped.The method used for this improvement process is the system or concept of Six Sigma namely DMAIC. From the DMAIC method, the tools used for the analysis process are the Pareto, Fishbone, 5W1H and Data Sheet diagrams. These tools are core tools that are focused on finding problems that often occur at PT XYZ. From the results of this improvement, a design is got to make the cleaning process aids, there were changes in parameters in the production process by reducing the current density and temperature in the Copper machine with a temperature of 30OC and current density of 20 A / dm2. The research and improvements that have been made are 94.45% with a total pinhole wastage of 1 cylinder unit.

Chili (cabai rawit) is one commodity that is very significant for people's daily consumption. However, the price of chili often experiences a significant increase. This condition will make the sales of chili decrease dramatically if the price rises. In addition, the margins felt by farmers to sellers of chili in the traditional market are uneven. this is also felt by other vegetable sellers. This research aims to identify the supply chain network of chili in Bekasi Regency. The margin of each stage in the supply chain network is also identified. This research employs descriptive analytical. Descriptive analytics is a preliminary stage of data processing that creates a summary of historical data to yield useful information and possibly prepare the data for further analysis. Data collection method used is by direct observation in Bekasi regency and other locations associated with suppliers of chili, then we employ direct and a phone interview with respondents. The finding shows that there are three main stages in supply chain of chili in Bekasi Regency, namely producer, distributor and consumer. The consumers can buy the product from three channels, that shows the flows of product from producer to consumer. The share of margin in the producer stage for the second flow is lower than the first flow, with the value 56.25% from 75%, then, the third flow is higher than the second flow but still lower than the first flow, with the value 64.29%.
