Abstract

The maintenance process and preventive measures on paper machines need to be studied further, this will affect the production process and paper machine performance. This study aims to determine the criticality of the drying machine failure and determine the preventive measures that must be taken in the maintenance of the dryer and determine the time interval for the maintenance of the dryer machine components. To overcome this problem, this research was made using the Reliability Centered Maintenance (RCM) method. RCM can be interpreted as a process used in determining what to do for the machine, wherein in the RCM methodology there is one FMEA calculation in dealing with critical components in the dryer. Based on data processing and analysis using the RCM method, the maintenance time interval results from the maintenance of the dryer component. The results found are drums/cylinders with maintenance intervals of 82.7 hours, components of all pipes with maintenance intervals of 91.1 hours, and gear components with maintenance intervals of 110.7 hours. The implications for the company's factory regarding preventive maintenance intervals will have an impact on improving the production process and performance of paper machines through early prevention of machine failures that often occur.

Abstract

Many objects around us use paper-based materials. Recycle fiber is an alternative raw material with great potential to meet fiber needs and overcome environmental problems. Paper with virgin pulp raw materials has a higher production cost than paper with recycled fiber raw materials. Apart from fiber raw materials, the chemicals used also cause high production process costs. Currently, the industry uses a double retention system for $ 63,022.5 per month; this cost comes from using more chemicals. This study aims to determine the effect of the use of single retention on machine run ability and the quality of paper produced and to find out how much production cost savings from the use of single retention. In this study, brown paper was made using CPAM chemicals as retention materials and silica as comparison retention materials with doses of 0.25kg/ton, 0.5kg/ton, 0.75kg/ton, and 1kg/ton, respectively. Then, wet-end properties testing was carried out, which included drainage and FPR. Furthermore, dry-end properties testing, which included internal bonding, concord, ring crush, and tensile testing, was carried out on a laboratory scale. The results showed that using a maximum dose of cpam of 0.25kg/ton got better results. In using cpam above 0.25 kg/ton, quality degradation results are obtained, but the drainage produced continues to increase as the dose increases; this is influenced by the amount of floc formed in the stock, thus affecting the run ability of the machine. After research and calculations with the application of single retention in the brown paper manufacturing process, considerable cost savings were obtained, and quality can be maintained using strength agents.
