Abstract

Pulau Enggano dengan luas ± 400,6 km2 (± 40.600 hektar) adalah sebuah pulau kecil terluar di Provinsi Bengkulu yang terletak di Perairan Barat Sumatera, dan termasuk wilayah Kabupaten Bengkulu Utara. Salah satu sumberdaya alam yang dominan di Pulau Enggano adalah ekosistem terumbu karang yang memberikan manfaat begitu besar bagi kehidupan masyarakat di Pulau Enggano. Penelitian ini bertujuan untuk menghitung valuasi ekonomi ekosistem terumbu karang di Pulau Enggano, untuk kepentingan perencanaan pemanfaatan dan pengelolaan secara berkelanjutan. Penelitian ini dilakukan dengan Metode Survai. Data parameter kualitas air dikumpulkan dengan pengukuran langsung di lokasi penelitian. Data untuk menghitung nilai keberadaan ekosistem terumbu karang dikumpulkan dengan metode wawancara terhadap 180 orang responden yang dipilih secara purposive sampling. Nilai ekonomi total ekosistem terumbu karang dianalisis dan dihitung berdasarkan nilai manfaat langsung, nilai manfaat tidak langsung, nilai manfaat pilihan dan nilai manfaat warisan. Nilai rata-rata parameter perairan di perairan Pulau Enggano secara berturut-turut adalah suhu (29,660C), salinitas (35,06 ‰), kuat arus (2,13 m/s), kecerahan 5,33 m), Oksigen Terlarut/DO (7,39 mg/l), dan pH (7,13). Nilai parameter perairan menunjukkan kondisi perairan yang masih baik dan belum tercemar sehingga dapat mendukung keberadaan dan pertumbuhan ekosistem terumbu karang di Perairan Pulau Enggano. Luas ekosistem terumbu karang di Pulau Enggano ± 5.097 hektar. Nilai manfaat ekonomi total ekosistem terumbu karang adalah Rp. 176.901.038.387,- per tahun, yang terdiri dari nilai manfaat langsung Rp. 561.327.640,- per tahun; nilai manfaat tidak langsung Rp. 46.342.500.000,- per tahun, nilai manfaat pilihan Rp. 2.516.077.983,- , nilai manfaat keberadaan Rp. 127.425.000.000,- per tahun dan nilai warisan Rp. 56.132.764,- per tahun.

ECONOMIC VALUATION OF CORAL REEF IN ENGGANO ISLAND, NORTH BENGKULU REGENCY, BENGKULU PROVINCE. Enggano Island with area of ± 400.6 km2 (± 40,600 hectares) is an the outer  small island in Bengkulu Province that located in the West Coast of Sumatra, and include of North Bengkulu Regency. One of the dominant natural resources in Enggano Island is a coral reef ecosystem that provides enormous benefits to people's lives in Enggano Island. This study aims to calculate the economic valuation of coral reef ecosystems in Enggano Island, for stake of planning, utilization and sustainable management. This research is done by Survey Method. The data of water quality parameter was collected by direct measurement at the study location. Data to calculate the existence value of coral reef ecosystem was collected by interview method to 180 respondents that chosen by purposive sampling. The total economic value of coral reef ecosystems is analyzed and calculated based on the direct value, indirect value, option value and bequest value. The average values of water parameters in Enggano Island waters are (29,66 oC), salinity (35.06 ‰), current speed (2.13 m/s), water brightness (5.33 m), Oxygen Dissolved (7.39 mg / l), and pH (7.13). The parameters of waters shows the condition of the waters are still good and not contaminated so it can support the existence and growth of coral reef ecosystems in Enggano Island waters. The wide of coral reef ecosystem in Enggano  Island ± 5,097 hectares. The total economic value of coral reef ecosystem is Rp.176,901,038,387,- per year, that consisting of direct value Rp. 561,327,640,- per year; indirect value Rp. 46,342,500,000, - per year, the option value Rp. 2,516,077,983, - per year, the existence value Rp. 127.425.000.000,- and the bequest  value Rp. 56,132,764,- per year.
