The tropical forests cover 24% of tropical land area. They are the most productive terrestrial ecosystems
on earth with high priorities for biodiversity conservation. These forests store a substantial amount of carbon in
biomass and soil, and they also regulate the transfer of carbon into the atmosphere as carbon dioxide (CO2).
Indonesia is having the third tropical forest area in the world after Brazil and Congo. Over 50 years forest has been
felled both legally as well as illegally. High rate of forest degradation resulted from unsustainable forest
management, rampant illegal logging, forest area encroachment, conversion and natural disaster. All urges rapid
improvement of management system of Indonesia’s forest resources (Holmes, 2002). Forest certification is one tool
that can support the achievement of sustainable forest management goal. Under current operation of join
certification protocol between the Forest Stewardship Council (FSC) and the Indonesian Ecolabelling Institute (LEI)
in Indonesia, forest management units must be able to show the required performance indicated in LEI criteria and
indicator as well as FSC principles and criteria to attain certification of their products. The gap between current
practices and performance required by forest certifications schemes is still enormous. The performance of forest
certification system from LEI is determined very much by the human that is involved in the process of planning and
operation. The name of certification system is chain of custody (CoC) certification. CoC operation involves
activities such as tracing raw material from the forest to the factory, through shipping and manufacturing, to the
final end product. In all of the above processes, the roles of human are critical, although the specific roles played
from one process to another are different. In this paper we present an identification of human aspect and other
factors that predominantly affect CoC system performance
