Analisis Kinerja Mesin Pompa Soda Ash Dengan Perhitungan Overall Equipment Effectiveness Dan Usulan Perbaikan Dengan Total Productive Maintenance Di IPA PDAM Tirtanadi Sunggal

Abstract

Perusahaan Daerah Air Minum (PDAM) or Water Supply Regional Company Tirtanadi is a Regional Owned Enterprises Level I of North Sumatra engaged in the provision and distribution of drinking water in Medan City and surrounding. The background of the study is there are some problems with the Soda Ash pump engine, such as the engine stopping suddenly, decreasing the normal speed of the engine, and also the unsuitable results of production. This will cause losses to the company because not only to reducing the level of efficiency and effectiveness of the machine/equipment but also resulting in costs that must be incurred due to the damage. The soda ash pump functions to put soda ash to neutralize or increase the pH of the processed water. This study aims to find out the effectiveness level or soda ash pump engine performance and the dominant factors in causing losses. Total Productive Maintenance is a program that involves all personnel in the company as well as maintaining for all company service facilities. In Total Productive Maintenance, it was conducted the measurements of Overall Equipment Effectiveness (OEE) value included vailability performance, quality, and Six Big Losses values including breakdown losess, setup, and adjustment losses, reduced speed losses, idling and minor stoppages, network losses, and yield losses. Through the Pareto and Fishbone diagrams, it was determined the dominant factors in losses and causes of losses. Based on the results of the study, the OEE value obtained from the soda ash pump engine was 73.61%, where the condition was still below the International OEE value of 85% and losses were also obtained such as idling minor stoppages and reduced losses, namely each with a percentage of 18.39 % and 5.1%. Thus, based on the calculation results of the OEE value and losses in dominant, so the company must evaluate and apply the TPM concept based on 8 pillars and 5 S.
