Wijaya, BayuTara (2015) Model Pertumbuhan Ikan Dengan Faktor Kualitas Pakan Di Kolam Air Limbah Oksidasi. Magister thesis, Universitas Brawijaya.
Abstract
Pada tesis ini dibahas tentang model pertumbuhan ikan dengan melibatkan parameter baru, yakni kualitas pakan ( q ) yang ditentukan berdasarkan rasio nitrogen-karbon. Model yang dianalisis berbentuk model persamaan diferensial pertumbuhan ikan di kolam air limbah oksidasi dilihat ari aspek anabolisme dan katabolisme secara individu. Fungsi q sebanding dengan efisiensi asimilasi pakan ( b ), persentase pakan terasimilasi untuk katabolisme ( a ), dan laju asupan pakan Model pertumbuhan ikan yang dikonstruksi, diterapkan pada pertumbuhan ikan Nila tilapia ( Oreochromis niloticus ). Model pertumbuhan ikan akan melambat apabila rasio nitrogen-karbon dalam pakan lebih besar daripada rasio nitrogen-karbon yang diproduksi ikan saat nitrogen erbatas, sebaliknya akan meningkat apabila rasio nitrogen-karbon dalam pakan lebih kecil daripada rasio nitrogen-karbon yang diproduksi ikan saat nitrogen terbatas. Pertumbuhan yang elambat, juga dipengaruhi fungsi b yang relatif kecil dan nilai Biochemical Oxygen Demand (BOD) yang cukup tinggi. Secara keseluruhan berdasarkan hasil simulasi dan observasi enambahan parameter q dapat terlihat pengaruh yang cukup bagus, dengan kondisi fungsi b ernilai besar dan nilai BOD tidak mendekati BOD max .
English Abstract
In this sis we discussed fish growth model including new parameters feed quality ( q ) are determined based on nitrogen-carbon ratio. model is analyzed in form of differential equation model of fish growth in wastewater oxidation ponds views from aspect of anabolism and catabolism individually. Function q is proportional to food assimilation efficiency ( b ), percentage of assimilated feed for catabolism ( a ), and rate of feed intake. Fish growth model are constructed, be applied to growth Nile tilapia ( Oreochromis niloticus ). Fish growth model will decrease if nitrogen-carbon ratio which is produced by fish during limited nitrogen have greater than nitrogen-carbon ratio in fish, o rwise will increase if nitrogen-carbon ratio which is produced by fish during limited nitrogen have smaller than nitrogen-carbon ratio in fish. Decreasing growth, also influenced by function b are relatively small and Biochemical Oxygen Demand (BOD) values are enough high. Overall results of simulations and observations, parameter q has fair influence to fish growth model with condition b function has greater values, and BOD values close to BOD max values.
