1. Introduction
According to data from Ministry of Agriculture of Indonesia in 2009, the amount of coconut production
reached about 3.38 million metric tons. Growth rate of production is predicted up to 0.86% /annum. Virgin coconut
oil is one of valuable product from coconut that applied for health and cosmetic product. FAO and APCC [1]
reported that VCO production in Asia Pacific region increased up to 5%. It is stated that VCO in local market in
Indonesia and international demand also increased after being introduced from the early 2004 [2]. It is predicted that
VCO demand is still increasing due to demand from local and international market.
Along with increasing of VCO (virgin coconut oil) production, wastewater by-product is also generated. In
VCO traditional wet processing, a coconut milk is processed by adding water into grated coconut to extract coconut
milk [3]. Excess water was separated from coconut milk by using decantation process. The water is usually released
to environment due to low of oil content (Figure 1).
