Abstract: A common method of moving the seeds is a short-distance transport with a limited density of fish. Therefore, it is necessary to have a transport system that can move the seeds to a raising area in a relatively long time, with high density and high survival rate. This study used a combination of zeolite (20 g/ℓ) and active carbon (10 g/ℓ) on tilapia seeds strain BEST with a size of ± 0.22 g/ℓ fish with a high density. Addition of supplement materials such as zeolit and active carbon were aimed to raise and maintain water quality during the transportation process, so the highest density could be attained. This study aimed to determine and find out the effectiveness of zeolite and active carbon in maintaining the quality of water in a closed transportation so as to know the optimal density of tilapia seeds strain BEST transported for 16 hours and to minimize the posttransport of mortality rate. This study consisted of two stages. The preliminary stage was to measure the level of oxygen consumption, ammonia excretion rate, fish fasting ability, and to determine the optimum density of tilapia BEST in a closed transportation. Transport time was 16 hours and the post-transport raising was 14 days for treatments with a density of 300, 500 and 700 fish/ℓ. The study result showed that density of 300 fish/ℓ is more effective compare to other treatment with a survival rate of 96%, highest Specific Growth Rate, namely 5,96%, and survival rate after transportation was 85%. However, when viewed from the profit, the optimum treatment density of 700 fish/ℓ had a profit of Rp 86.280, with a survival rate of 79% for 16 hours.
Dalam penyelenggaraan usaha pembesaran ikan, seringkali benih-benih yang memenuhi syarat diperoleh dari tempat pembenihan yang letaknya berjauhan dari tempat pembesaran. Sistem pengangkutan yang umum yaitu sistem transportasi tertutup dengan jarak pendek dan kepadatan ikan terbatas. Maka diperlukan suatu sistem pengangkutan yang dapat memindahkan benih ke tempat pembesaran jarak jauh, dengan kepadatan tinggi dan tingkat kelangsungan hidup yang tinggi. Penelitian ini menggunakan kombinasi zeolit 20 g/ℓ dan karbon aktif 10 g/ℓ pada benih ikan nila BEST ukuran rata-rata 0,22 g/ekor dengan kepadatan tinggi. Penambahan material zeolit dan karbon aktif ini diharapkan dapat mempertahankan kualitas air selama pengangkutan, sehingga kepadatan tinggi dapat dicapai. Penelitian ini bertujuan untuk menentukan efektifitas zeolit dan karbon aktif dalam mempertahankan kualitas air pada pengangkutan tertutup sehingga dapat mengetahui kepadatan optimal benih ikan nila BEST yang diangkut selama 16 jam dan meminimalisir tingkat kematian pasca pengangkutan. Tahapan penelitian dimulai dari mengukur tingkat konsumsi oksigen, laju eksresi amoniak, kemampuan puasa ikan, penentuan kepadatan optimum benih ikan nila BEST pada transportasi tertutup. Transportasi dilakukan selama 16 jam dan pemeliharaan pasca transportasi selama 14 hari untuk perlakuan dengan kepadatan 300, 500 dan 700 ekor/ℓ. Hasil penelitian menunjukan perlakuan 300 ekor/ℓ lebih efektif dibandingkan perlakuan lainnya dengan tingkat kelangsungan hidup selama pengangkutan sebesar 96%, LPH paling tinggi 5,96% dan tingkat kelangsungan hidup pascatransportasi sebesar 85%. Namun demikian dilihat dari keuntungan perlakuan 700 ekor/ℓ lebih baik mencapai Rp 86.280 dengan tingkat kelangsungan hidup sebesar 79% selama pengangkutan 16 jam.
