Abstract

This research was conducted in February 2021 in the waters of Pandan Island, West Sumatra Province. This study aims to determine the relationship between coral cover and the density of megabenthos found in the Pandan Island area. The method used in this study is a survey method. Coral cover data was collected using the LIT (Line Intercept Transect) method and megabenthos data was collected using the Benthos Belt Transect method. The results showed that Pandan Island had a good percentage of coral cover. The highest density of megabenthos was trokha snails found at each station, while the lowest density was Acanthaster planci which was only found at three stations and had a percentage of coral cover that had an influence on megabenthos density. Then it was also found that there was a strong negative relationship between coral cover and non-economic megabenthos, which indicated that there was an effect of the percentage of coral cover on both economic and non-economical megabenthos.

On the other hand Dumai City also has a stretch of mangrove along the coast which is feared to experience problems due to these activities. This study aims to determine the economic value of mangrove ecosystems in Dumai City. The study, conducted in March 2019. The method used in this study is a survey method. The determination of sampling points was done by purposive sampling in 4 (four) stations: Station I (Bangsal Aceh), Station II (Muara Sungai Masjid Area), Station III (Muara Sungai Dumai), and Station IV (Tanjung Palas) Dumai City, Riau Province . The method used to estimate the economic value of resources is the Total Economic Value (TEV). WTP analysis with the Contingent Valuation Method (CVM) is likened to an approach to measure how much willing to pay. Direct use value such as the use of mangrove wood, mullet fish, shrimp, and mangrove crabs is Rp. 97,258,416,000.00 and indirect use values measured from the value of the construction of breakwaters and mangroves as nursery ground in the amount of Rp. 4,616,250,000.00. The choice of value measured from the amount of mangrove utilization as a recreation area is Rp. 1,836,000,000.00. The value of the existence and inheritance value calculated from the community's willingness to pay WTP (Willingnes To Pay) of Rp. 670,080,000.00 and Rp. 233,360,000.00, and non-use value of Rp. 893,440,000.00. So that the total economic value of mangrove forests in the coastal area of Dumai City per year is Rp. 104,604,106,000.00.
