ESTIMASI DAYA DUKUNG LINGKUNGAN KERAMBA JARING APUNG, DI PERAIRAN PULAU SEMAK DAUN KEPULAUAN SERIBU, DKI JAKARTA

Penelitian ini menguraikan estimasi daya dukung lingkungan perairan terhadap kegiatan budidaya. Analisis yang digunakan yaitu estimasi limbah organik dan pendugaan daya dukung perairan. Jenis ikan yang dibudidayakan yaitu ikan kerapu. Hasil penelitian menunjukkan, bahwa beban limbah dari kegiatan budidaya sebesar 1.04 kg N/hari/ unit. Estimasi beban limbah antropogenik yaitu 20.56 kg N/hari. Berdasarkan pendekatan beban limbah N, daya dukung lingkungan perairan Pulau Semak Daun terhadap kegiatan budidaya adalah 114 unit keramba jaring apung. Diasumsikan satu unit keramba jaring apung menghasilkan 300 kg ikan, maka diperoleh 28.2 ton produksi ikan yang dapat ditampung.This research describing about the estimation of carrying capacity of water environment against cultivation activities, whereas the type of fish that has been cultivated was grouper fish. Organic waste estimation and carrying capacity of water environment prediction were used to analyze this research. This research resulting that waste loads from cultivation activities were equal to 1.04 kg N/ day/ unit and the estimation of anthropogenic waste loads were 20.56 kg N/ day. Based on approach of waste loads N, carrying capacity of water environment of Semak Daun Island against cultivation activities is 114 units of floating net cages. Assumed a unit of floating net produce of 300 kg of fish, it acquired 28.20 tonnes of fish production can was accommodated
