Abstract
Penelitian ini bertujuan untuk mengetahui : (1) Daya dukung perairan Danau Toba Desa Horsik dilihat dari sifat fisika, kimia air (Kecerahan, Suhu, DO dan pH), kedalaman lokasi KJA dan jarak KJA untuk budidaya ikan sistem keramba jaring apung. (2) Sebaran produksi ikan nila sistem KJA menurut sebaran daya dukung perairan (kecerahan, suhu, DO dan pH), kedalaman lokasi KJA dan jarak KJA untuk budidaya ikan sistem keramba jaring apung di Desa Horsik Kecamatan Ajibata Kabupaten Toba Samosir. Penelitian ini dilaksanakan di Desa Horsik Kecamatan Ajibata Kabupaten Toba Samosir. Jenis Penelitian ini merupakan pengukuran kualitas air perairan Danau Toba untuk budidaya ikan nila yang ditinjau dari karakter fisik air (kecerahan dan suhu), karakter kimia air (DO dan pH) dan parameter yang mempengaruhi seperti kedalaman dan jarak KJA. Populasi penelitian ini adalah perairan sekitar Danau Toba Desa Horsik. Sampel penelitian ini adalah perairan Danau Toba untuk KJA. Teknik pengumpulan data yang digunakan yaitu teknik pengukuran, teknik observasi, teknik komunikasi langsung dan teknik dokumenter, kemudian data dianalisis dengan teknik analisis deskriptif kualitatif. Hasil penelitian menunjukan : (1) Daya dukung perairan Danau Toba Desa Horsik untuk budidaya ikan sistem KJA memiliki Suhu yang sesuai berkisar 25-26,70C, DO 7,36-7,40 , pH 7,48-7,50 dan Jarak yang sesuai berdasarkan syarat hidup Ikan Nila untuk budidaya berkisar 23-35 m. Parameter yang tidak sesuai dengan syarat budidaya adalah Kecerahan 4,7 m dan kedalaman 5,8 m kurang dari syarat daya dukung, berada pada KJA titik I. Dengan demikian, rata- rata SL > DL, dikatakan surplus. (2) Sebaran produksi menurut sebaran Daya Dukung Perairan Danau Toba Desa Horsik menunjukan produksi ikan yang Daya Dukungnya sesuai untuk budidaya Ikan Nila sistem KJA memiliki hasil yang baik dan optimal yakni, 76%, berbeda dengan produksi yang memiliki Daya Dukung yang tidak sesuai dengan syarat hidup Ikan Nila dengan hasil hanya 58
