Abstract

Disolved oxygen plays an important role for fish living in its life environment. Information on the ammount of oxygen consumption of a fish in certain volume of water is needed in order to give balancing between the ammount of disolved oxygen and fish in it. The objective of this research is obtaining oxygen consumption level of a juvenile of humpback grouper (Cromileptes altivelis) of 5-7 cm body length. Oxygen consumption of fish was measured using a tube that equiped with DO tool (dissolved oxygent, DO), and the tube was filled by sea water. Measurement of oxygen con-sumption of juvenil was done by measuring the concentration of dissolved oxygen from sea water in the respirometer tube, began when fish had entered into the respirometer tube up to two hours observation. The result showed that oxygen consumption rate of a juvenile of humpback grouper (Cromileptes altivelis) of 5-7 cm length, is ranging between 0.816 and 1.734 mg/hour.

Abstract

Penggunaan polyurethane sebagai bagian dari sistem insulasi pada palka kapal penangkap ikan sudah sangat umum digunakan. Namun demikian takaran yang diaplikasikan masih berdasarkan pengalaman dan perkiraan pembuatnya.Salah satu kriteria teknis adalah densitas material insulasi (ρ). Tujuan penelitian ini adalah mendapatkan  nilai densitas insulasi yang  digunakan pada palka kapal penangkap ikan di Pekalongan. Palka dari dua kapal penangkap ikan dan bahan insulasi polyurethane digunakan sebagai obyek dalam penelitian ini untuk menentukan apakah densitas insulasi yang digunakan sudah memenuhi batas minimum. Nilai densitas standar yang digunakan adalah nilai densitas (ρ) polyurethane> 30 kg.m-3 (Dellino 1997).Hasil penelitian menunjukkan, nilai densitas insulasi yang bervariasi.  Pada kapal 1 densitas berkisar 28,15 kg.m-3-30,86 kg.m-3, sementara itu pada kapal 2 berkisar 31,67 kg.m-3-33,58 kg.m-3. Pada kapal 1 hanya 70% dindingpalka memiliki insulasi sesuai dengan standar, sementara pada kapal 2 semua dinding palka memenuhi standar yang digunakan.Kata kunci: densitas, insulasi, polyurethane, kapal penangkap ikan
