The mangrove ecosystem is one of the ecosystems that has high productivity in coastal and marine areas, especially in supporting the productivity of fishery resources. This is due to the function of the mangrove ecosystem as ecological and socio-economic. Therefore, to determine the high level of mangrove utilization in the coastal area of Siak Regency, an economic assessment of mangrove ecosystem services is necessary. This research aimed to study quantified mangrove ecosystem services in Siak Regency, Indonesia. Methods for data collection included field survey and interview, performed between July - August 2020. The economic value assessment comprised valuation on following service groups, i.e. supporting, provisioning, regulating and cultural services.

In conclusion, a total amount of economic value for mangrove ecosystem services in Sungai Apit District, Siak Regency was IDR 153,466,048,507,014 per year, which was equivalent to IDR 300,090,044,0 per hectare per year.
