The oil palm plantation industry in Indonesia is faced with a strong view which suggests that the development of oil palm plantations in Indonesia has an impact on environmental damage. One effort currently made by the Indonesian government to ensure the sustainability of the development of the palm oil industry is to create a sustainability standard called The Indonesian Sustainable Palm Oil (ISPO) which is mandatory. ISPO is a "guidance" for sustainable palm oil development, as well as a commitment to the implementation of various relevant laws and regulations in Indonesia. The purpose of this study is to determine the value of the ability of oil palm plantation companies in an area to meet the Indonesian Sustainable Palm Oil (ISPO) standards and identify the problems faced in achieving these standards. This research was conducted in the province of East Kalimantan in the period June 2012-May 2013. Evaluation of the company's ability to achieve the ISPO standard was carried out by the audit method, the results of the assessment of all parameters set according to the Principles, Criteria and Indicators contained in the ISPO provisions were then assessed in units percent. The results showed that the ability of plantation companies in East Kalimantan to meet ISPO standards had reached 79.14%. the capacity can still be increased up to 100% by increasing efforts to meet indicators that are not yet in accordance with ISPO regulations, namely; 1). Licensing and estate management systems, 2). Implementation of technical guidelines for oil palm cultivation and processing. 3). Environmental management and monitoring. 4). Responsibility towards workers. 5). Social and community responsibility. The determining factor for the achievement of ISPO standards is the commitment of plantation companies as business actors supported by adequate human resources to realize sustainable plantation development as well as the role of the government as the determinant of regulations in overseeing established policies. The socialization and training on the principles and criteria of ISPO standards to plantation companies needs to be immediately and more intensively carried out by the government together with the ISPO commission as an effort to accelerate the application of these standards. Dissemination and training are also needed so that the obstacles in achieving the standards of Indonesian Sustainable Palm Oil principles and criteria can be overcome, because these efforts are part of the success factors of ISPO implementation.
