PT. Inti Indosawit Subur is a company engaged in plantation and processing of crude palm oil (CPO) has a problem related to the effectiveness of the machinery / equipment caused by the six big losses. This can be seen by the frequency of downtime is increasing all the time due to the damage caused to machinery / equipment. Therefore, necessary measures are effective and efficient in the maintenance of machinery / equipment to be able to cope with and prevent such problems. Stages in efforts to increase efficiency in the production of this company is by measuring the effectiveness of machine / equipment using the Overall Equipment Effectiveness (OEE) followed by six big losses OEE measurements to determine the level of efficiency that is lost on the sixth factor of six big losses. Of the six factors are then sought what factors contributed most to the resulting lack of effectiveness of the digester press machine. With Pareto diagrams and cause-effect diagram can be analyzed major problems that cause high losses that result in low effectiveness digester press machine. The data used is the data for the period February 5 to March 6, 2013, with four research object digester press machine. During the period of availability ratio values obtained ranged between 73.84% - 84.14%. For the value of performance ratio ranged between 85.68% - 87.38%. And result quality ratio values ranged between 97.44% - 97.65%, so the value of the results obtained Overall Equipment Effectiveness (OEE) fourth digester press machine ranged between 62.39% - 71.53%. The machine with the highest OEE value is digester press machine 3 is equal to 71.53%. Of the four digester press machine entirely no machine that has a value above the standard of world class OEE is 85% (Hansen, 2001). This research shows that the breakdown of losses has donated the largest losses in the digester press machine is equal to 39.75%. Then followed reduced speed losses amounted to 34.25%, then setup and adjustment losses amounted to 24.92%, and the final yield / scrap losses 1.07% of the total losses.
