MAS BINTANG. Kajian Unit Penangkapan Jaring Kembung (Gillnet) di TPI Pantai Labu Kabupaten Deli Serdang. Dibimbing oleh PINDI PATANA dan TAJUDDIN SIREGAR.
Jaring kembung merupakan alat tangkap dengan target penangkapan ikan-ikan pelagis. Penelitian ini bertujuan mengkaji unit penangkapan jaring kembung dan menganalisis komposisi, diversitas, dominansi, ukuran dan analisis usaha. Penelitian ini dilaksanakan di TPI Pantai Labu Kabupaten Deli Serdang dari bulan Agustus sampai Desember 2015. Hasil penelitian didapatkan 3 jenis ikan yang terdiri dari ikan kembung sebagai hasil tangkapan utama sebesar 816,2 Kg sedangkan hasil tangkapan sampingan yaitu ikan tenggiri sebesar 65,1 Kg dan ikan selar sebesar 37,8 Kg. Selama penelitian nilai indeks diversitas rendah berkisar 0,18-0,35 sedangkan nilai indeks dominansi tinggi berkisar 0,83-0,93. Hal tersebut mengindikasikan bahwa selektivitas alat tangkap tinggi. Nilai laju tangkap pada alat tangkap jaring kembung (gillnet) HTU yaitu sebesar 40,81 kg/trip lebih tinggi dari pada HTS yaitu sebesar 5,145 kg/trip. Jaring kembung
(gillnet) menangkap ikan rata-rata 62,08% ukuran minimum layak tangkap. Analisis usaha untuk nilai Revenue-Cost Ratio (R/C) sebesar 1,3 yang berarti usaha penangkapan layak dilakukan dan nilai Payback Period (PP) sebesar 0,7 tahun.
Kata Kunci : Alat tangkap jaring kembung (giilnet), Komposisi tangkapan, Analisis Usaha.
ABSTRACT
MAS BINTANG. The Study Units of Bloating Net (gillnet) in the Pumpkin TPI Deli Serdang Regency. Under academy supervision by PINDI PATANA and TAJUDDIN SIREGAR.
Bloating net is a fishing gear which has the pelagic fishes as the fishing target. The research that to review unit bloating and analyze the composition, diversity,dominance, size and effort analysis. This research was conducted in Pumpkin TPI Deli Serdang Regency from August until December 2015. Result of the research found 3 species of fish those were Rastrellinger sp. as the mayor catch is 816.2 kg while the minor catches is Scomberomorus commerson as 65.1 kg and Selaroides sp as 37.8 kg. During research, the value of diversity index both appliance catch have low between 0.18-0.35 while the value of dominance index high between 0.83-0.93. It indicate that selectivity both appliance catch’s high. The rate value at the appliance catch HTU Bloating Net (gillnet) is equal to 40.81 kg/trip, higher from HTS that is aqual to 5.145 kg/trip. Bloating Net (gillnet) catch the fish with an average competent minimum size. The effort analysis to value the Revenue-Cost Ratio (R/C) of 1.3, which means that the effort is worth doing and worth Payback Period (PP) of 0.7 years.
Keywords: Bloating net fishing gear (gillnet), composition of catches, Effort Analysis.
