Abstract

Unisba's waste problem was solved by establishing a compost hut to sort organic, recyclable, and residual waste, which the Clean and Green Team managed. Organic waste is composted; recyclable waste is separated, cleaned, and sold to Bandung City's main waste bank; and residual waste is transported by the Cleaning Technical Unit (UPTD) Bandung City. Unisba has launched a long-term initiative to become a zero-waste campus by managing waste independently. As part of this program, the Shokyakuro -FTU Incinerator machine will process residual waste on Campus 2 Unisba Ciburial and replace the processing of residual waste by UPTD. This service activity aims to use the Shokyakuro -FTU Incinerator machine to process residual waste at Campus 2 Unisba in Ciburial District, Bandung Regency. All cleaning staff practice in Campus 2 Unisba Ciburial operating the Shokyakuro -FTU Incinerator machine as part of the implementation process. Following training, machine operating procedures are developed to make it easier for cleaning staff to use the machine in the future.

Abstract

PT. ABC is a manufacturing company that produces Electric Power Steering (EPS) Housing components. For the past three months, there have been problems with the EPS production process. The problem is related to the finding of defective products which on average reached 3.9% of the total production, and has exceeded the maximum limit allowed by the company, which is 2%. This study aims to overcome these problems by making improvements using the DMAIC method in the hope of finding the root cause of the emergence of defects and making improvements to reduce the number of defects that occur. The improvement results have shown that the number of defects reduced from 3086 pcs to 1948 pcs per 22 working days or decreased by 0.54% with an increase in sigma level from 3.95 to 4.01 sigma. In this case, DMAIC implementation is effectively reduced defects by 1.5% based on the sigma level. To achieve a 6-sigma level equivalent to a world-class industry, companies must make continuous improvements by fixing other root causes.

Abstract

One of the leading manufacturers in packaging paper in Indonesia has six production machines. To keep the production machine always in the best condition, then the role of maintenance is significant. One of the production machines, namely paper production machine 2 (PM2), has experienced increasing the number of breakdowns significantly, resulting in increased downtimes. Sudden failure causes a lengthy repair time and results in considerable production loss. The corrective maintenance method that is running at this time still not effectively reduce downtime. To minimize the number of downtimes, preventive maintenance is needed, and therefore the Reliability Centered Maintenance (RCM) method is selected. Besides applying quantitative analysis such as Mean Time To Repair (MTTR), Mean Time To Failure (MTTF), reliability, and preventive cost calculations. This method also conducts qualitative analysis such as Functional Block Diagrams (FBD), critical engine analysis, Fault Tree Analysis (FTA), and Failure and Mode Effect Analysis (FMEA). After implementing the preventive maintenance, there is an increase in reliability in the sub-system of the press section of the paper production machine 2 from only 43% to 56%, while the repair cost has been reduced by Rp 393,258,670 from Rp 5,724,825,736 to Rp 5,331,567,066 each time replacement of components in the press section. This decrease in costs will contribute to the profits earned by the company because it saves maintenance costs.
