This study aims to determine the efficiency of the sugar industry factories inIndonesia. These plants are PG Jatitujuh, PG Karangsuwung, PG Sindanglaut, PG Subang,PG Tersanabaru, PG Gondangbaru, PG Jatibarang, PG mojo, PG Pangka, PG Rendeng. Dataused in this study is secondary data, the source data comes from the Indonesian SugarCouncil with the years of the study was taken from 2001 to 2010. Variables used in this studyconsisted of three input variables and two output variables. Variable input consists of thecane milled, the total area, kapasits rollers, while the output variables consist of sugarproduction and production drops. The results of processing by using the Data EnvelopmentAnalysis (DEA) in the period 2001-2010 shows that there are only three plants in a row isconsistent with maintaining the efficiency of 100%. Three factories are PG Jatitujuh, PGJatibarang and PG Sindanglaut. While the other two factories, namely PG Rendeng and PGGondangbaru showed a decreased efficiency level of performance each year with numbersbelow 100%.
