Why Tree analysis to find the root cause of environmental problem (case study on geothermal power plant)

摘要

Concept of sustainable development were introduced in 1987 by the world commission on environment and development, chaired by Gro Harlem Bruntland. Sustainable development is a development process that is principled to meet the needs of the present without compromising with the risk of fulfilment of the needs for future generations.

The 2005 World Summit outlined sustainable development consisting of three main pillars, includes economic, social and environmental interdependence and strengthening. Environmental aspects sometimes having problems either because they are directly caused by human error or mismanagement. Root cause analysis method is needed to find out the contributing factor of the problems. In this research, Why Tree method is used along with the RCA-Constructor software to investigate the root cause of geothermal power plant’s environmental problems in Indonesia. This finding is expected to formulate appropriate and continuous improvement steps to prevent the similar events in the future.
