Abstract

The Environmental Sensitivity Index (ESI) is a description of the biological, socio-economic and socio-cultural values of a particular coastal and marine area used as a priority response to oil spills, shown on a map by applying spatial analysis using geographic information system technology. The purpose of this research was to analyse mangrove ecosystem area in Banggai and Banggai Islands Regency based on its vulnerability value by analyzing mangrove community structure and socio-economic services for local community. The research was conducted in nine sub-districts, among others: South Batui, Batui, East Luwuk, Lamala, Masama, Balantak, Bualemo (Banggai) and Bulagi and Buko (Banggai Islands). The study was conducted from August to November 2016, with field observations, direct interviews with communities and local government and literature review. The results of spatial analysis of ESI in the coastal areas of Banggai and Banggai Islands are obtained from sensitivity values of medium and sensitive. Areas with moderate sensitivity are Batui, East Luwuk, Masama, Lamala, Balantak and Bualemo sub-districts with grades of 16,78 – 24,35. The value of ESI with sensitive category ranges from 38,24 – 57,54 in Bulagi, Buko and South Batui sub-districts. Keywords: mangrove ecosystem, Environmental Sensitivity Index (ESI)

Abstract

This study aims to determine how big the value of the total economic benefits of mangrove forest by using the concept of economic valuation to calculate the value of the benefits of natural resources which exist in 9 District of Banggai Regency and Banggai Island Regency located in Peleng Strait Costal Area there are: District of Batui Selatan, Batui, Luwuk Timur, Lamala, Masama, Balantak, Bualemo (in Banggai Regency Area) and District of Buko and Buko Selatan (Banggai Island Regency). The research was conducted in August to November 2016, by conducting field observations and interviews directly to the community and local government. Based on the results obtained that indicate the area of mangrove forest ecosystems in Peleng Strait Costal Area with a broad ± 167 ha, have total value of economic benefits amounted Rp 26,591,841,888/year with the largest contributor to the value of benefits is from the value of indirect benefits that is the value of the benefits of mangrove forests as a buffer abrasion or sea water waves is about Rp 16.030.000.000. The total value of economic benefits can be used as a reference or basic comparison for the community and the government in determining the policy management and utilization of existing mangrove forests. Keywords: mangrove forest ecosystems, benefits value, economicvaluation
