<p>The extending of protein and energy of the Swimming crab should be on certain limit that could be give maximum growth. The objective of this research are to determine of the protein level and optimum energy ratio of protein (C/P) at <em>rajungan</em> (<em>Portunus pelagicus</em>). The Crab-5 (C-5) stage used in the experiment, maintained in the topless (volume of 2 liters), with density of 1 crab/glass. There were seven of the experimental diets namely A (protein of 30%; C/P of 8 kkal), B (30%; 9.5), C (35%; 8), D (35%; 9.5), E (40%; 8), F (40%; 9.5) and G (45%; 8) with extending of food are 5 time of daily. Complete randomize design with 2 of factor and 3 of replication use in the experiment. The results of this experiment showed that interaction of the protein level and the energy ratio of protein is influence to the growth rate of daily and retention of lipid. The D is the best in give of the growth rate of daily, the consumption of food, the retention of protein, and the frequency of moulting (P<0.05).</p> <p>Keywords:  Protein level, protein to energy ratio, growth, <em>rajungan</em></p> <p> </p> <p>ABSTRAK</p> <p>Penelitian ini bertujuan untuk mengetahui kadar protein dan rasio energi optimum dalam pakan yang menghasilkan kinerja pertumbuhan rajungan yang terbaik. Rajungan yang digunakan pada percobaan ini adalah stadia Crab-5 (C-5). Rajungan dipelihara dalam toples volume dua liter air yang diisi air sebanyak 1 liter dengan padat lebar 1 ekor per toples. Pakan yang digunakan sebagai pakan percobaan terdiri atas 7 jenis yakni A (protein of 30%; C/P of 8 kkal), B (30%; 9,5), C (35%; 8), D (35%; 9,5), E (40%; 8), F (40%; 9,5) and G (45%; 8). Pemberian pakan dilakukan sebanyak 5 kali sehari sampai rajungan kenyang. Rancangan Percobaan yang digunakan adalah rancangan acak lengkap dengan 3 ulangan. Hasil penelitian menunjukkan bahwa interaksi kadar protein dan rasio energi protein pakan mempengaruhi laju pertumbuhan harian dan retensi lemak. Pakan D memberikan laju pertumbuhan harian, konsumsi pakan dan retensi protein tertinggi. Sementara frekuensi moulting yang tinggi juga dicapai pada perlakuan pakan D.</p> <p>Kata kunci: Level protein, rasio energi protein, pertumbuhan, rajungan</p>

1. Diets containing varying levels of crude protein (CP) in the range 9.5–18.5% with and without supplements of diammonium citrate (DAC) as a source of non-protein nitrogen (NPN) were given to 160 growing chicks from 2 to 4 weeks of age, and their livers were assayed for glumate dehydrogenase (GDH) activity.2. Growth rate and total liver protein were increased by raising the protein level from 9.5 to 18.5% CP. Chicks receiving 9.5 or 12.5% CP were heavier when they had also received 1.94% DAC. At 18.5% CP the addition of 3.88% DAC depressed growth.3. GDH activity per unit liver weight and total GDH activity increased with dietary protein level but there were no consistent responses to DAC supplements. It was concluded that liver GDH activity did not provide a useful index of the utilization of NPN.
