Agus Romadhon

Abstract


ABSTRAK

Ekosistem terumbu karang bagi masyarakat pulau-pulau kecil memiliki peran sebagai penyedia sumberdaya perikanan.  Pulau Sapudi, terdiri dari masyarakat yang memiliki mata pencarian utama sebagai nelayan dan 569 nelayan diantaranya menjalankan praktek penangkapan ikan karang secara destruktif. Penelitian ini bertujuan untuk mengestimasi nilai manfaat dari ekosistem terumbu karang dengan menggunakan pendekatan efek produktivitas sebelum dan sesudah praktek penangkapan ikan karang secara destruktif. Hasil yang diperoleh menunjukkan bahwa nilai estimasi ekonomi aktual dari ekosistem terumbu karang di Pulau Sapudi berdasarkan data primer adalah Rp 21.027.933.840,00; sementara itu estimasi dari nilai manfaat sekarang adalah Rp 384.542.778,79 dan nilai estimasi manfaat bersih sekarang adalah Rp 239.081.334,38. Hasil juga menunjukkan melalui pendekatan data berkala diperoleh nilai estimasi dari manfaat ekosistem terumbu karang yang hilang selama kurun waktu 10 tahun. Estimasi nilai manfaat yang hilang yaitu sebesar Rp 5.097.140.400,00 atau sebesar Rp 2.842.800,00 per hektar.


ABSTRACT

Coral reef ecosystem for people in small islands had benefit as fisheries resources supplier. In Sapudi island  there are 569 fishermen household, who are running some economic activities, including destructive fishing practices. The purposes of this research is to estimate the benefit value of coral reef in Sapudi Island using Effect on Production (EoP) approach. This approach mainly applies to estimate the difference in value of productive output before and after the impact of activity. The results of this research show that the actual economic values of coral reef in Saoudi Island based on cross section data is Rp 21.027.933.840,00, while produce an estimation of present value of the benefit is Rp 384.542.778,79. Furthermore, the present value of residual rent is as of estimated to be Rp 239.081.334,38. Based on the time series appproach, it is estimated that a loss of benefit after 10 years has been occurred. Therefore foregone benefit value of coral reef in 10 years is Rp 5.097.140.400,00 or Rp 2.842.800.000,00 per hectare
