ABSTRACTThis experiment was conducted to evaluate the use of by product of corn ethanol industry, DDGS (distiller dried grain with soluble) and hominy as feed raw material on digestibility and the growth performance of humpback grouper Cromileptes altivelis juvenile. Three experimental diets containing isoprotein (48%) but different in DDGS contain were used. Diet A containing 0% of DDGS and hominy while diet B and C containing 10.13% (6.13% of DDGS and 4% of hominy) and 19.05% (15.05% of DDGS and 4% of hominy). Reduce of fish meal level in the diet was happen as a consequence of balancing amino acid. For digestibility experiment and Cr2O3 at level of 0.05% was used as a tracer. The feces were daily collected 30‒60 minutes after feeding for 14 days. Dry matter and protein were used as digestibility parameters. Completely randomized design with three treatments and two replicates was used in this experiment. Humpback grouper with an average weight of 11‒14 g were reared at floating net cages (FNG) of 3×2×1.5 m3. The stocking density for each cage was 167 fish/FNG and reared for six months. For digestibility measurement 30 fish were held in cylindrical fiber tank filled with 800 L of sea water. Fish were fed three times daily at satiation level. For maintaining net in a clean condition net was changed in every ten days. Feed consumption, digestibility of protein and total, growth performance indicator i,e specific growth rate, feed efficiency protein and lipid retention were used as evaluating parameters. The results showed that the fish fed with diet containing DDGS (6.13%) dan hominy (4%), at the level of 10.13% (diet B), shows similar growth performance indicators with the fish fed diet A (0% of DDGS and hominy) and the growth performance indicator was higher when being compared to those fish fed diet C (containing 19.05% of DDGS (15.05%) and hominy (4%)) (p<0.05). More over the inclusion of DDGS and hominy at the level of 10,13% give no negatif impact to feed palatability (shown by total feed consumption value) and digestibility of protein. The increasing level of DDGS and hominy more than 10% reduced palatability and protein digestibility. Based on this research, DDGS and hominy can be used up to 10% in the feed formulation of humpback grouperKeywords: digestibility, growth performance, DDGS, hominy, humpback grouper, Cromileptes altivelisABSTRAKPenelitian ini dilakukan untuk mengevaluasi pemanfaatan limbah jagung dari industri etanol dalam bentuk distillate dried grain with soluble (DDGS) dan homini sebagai bahan baku pakan terhadap kinerja pertumbuhan ikan kerapu bebek Cromiliptes altivelis. Ikan yang digunakan dalam penelitian ini adalah juvenil ikan kerapu bebek berukuran 11‒14 g. Ikan dipelihara dalam karamba jaring apung yang berukuran 3×1,5×2 m3 dengan kepadatan 167 ekor/jaring. Ikan diberi pakan sampai kenyang sebanyak dua kali sehari. Untuk menjaga agar jaring tetap bersih maka dilakukan pergantian jaring setiap satu sampai dua minggu sekali. Ikan dipelihara selama lima bulan dan setiap bulan dilakukan sampling. Tiga macam pakan digunakan dalam penelitian ini dengan kadar protein 47% dan rasio energi protein 10 kkal/g protein. Pakan A adalah pakan yang tidak mengandung DDGS dan homini, pakan B mengandung DDGS 6,13% dan 4% (total 10,13%), dan pakan C mengandung DDGS 15,05% dan Homini 4% (total 19,5%). Untuk mengevaluasi ketercernaan nutrien maka kromium oksida (Cr2O3) digunakan sebagai penelusur. Penelitian ketercernaan dilakukan di laboratorium dengan menggunakan fiber dengan volume 800 L. Rancangan acak lengkap dengan tiga perlakuan dan dua ulangan digunakan dalam penelitian ini. Hasil penelitian menunjukkan bahwa nilai ketercernaan nutrien tidak berbeda sampai total kadar DDGS dan homini 10,13% (pakan B) dan peningkatan DDGS serta homini sampai 19,05% (pakan C) menurunkan nilai ketercernaan. Ikan yang diberi pakan dengan DDGS sebesar 10,13% (pakan B) memiliki nilai efisiensi pakan, sintasan, laju pertumbuhan spesifik, konsumsi pakan dan retensi protein yang sama dengan pakan tanpa DDGS (pakan A), akan tetapi nilai-nilai tersebut lebih tinggi jika dibandingkan dengan ikan yang diberi pakan B (p<0,05). Retensi lemak ikan yang diberi pakan B memiliki nilai yang lebih tinggi jika dibandingkan dengan ikan yang diberi pakan A dan C. Dari penelitian ini dapat disimpulkan bahwa DDGS dan homini dapat digunakan sebagai bahan baku pakan ikan kerapu bebek sampai level 10,13% (DDGS 6,13% dan homini 4%).Kata kunci: pertumbuhan, ketercernaan, DDGS, homini, ikan kerapu bebek, Cromileptes altivelis

ABSTRACT Sludge worm (Tubifex sp.) as natural feed on catfish (Pangasionodon sp.) larvae rearing is available in limited amount especially during rainy season. It becomes a constraint factor for larvae rearing sector. This research was conducted to evaluate the appropriate initial age of catfish larvae to get artificial feed as sludge worm replacement. Evaluation was conducted on the growth and survival of catfish larvae in 14 days of culture. There were four treatments of feeding in triplicates i.e. larvae were given natural feed without artificial feed, given artificial feed started from d3, d6, and d9) with three replications. The results showed that larvae fed on artificial feed on d3 had the lowest growth compared to the other treatments, whereas the survival was not significantly different (P>0.05) among the treatments. As a conclusion, artificial feed could be used to replace natural feed for catfish larvae started at the age of nine days. Keywords: sludge worm, catfish larvae, artificial feed ABSTRAK Cacing sutra (Tubifex sp.) tersedia dalam jumlah terbatas terutama pada musim penghujan sebagai pakan alami dalam usaha pembenihan ikan patin (Pangasionodon sp.). Ini menjadi kendala dalam usaha pembenihan. Penelitian ini dilakukan untuk mengevaluasi umur larva ikan patin yang tepat untuk mulai diberi pakan buatan menggantikan cacing sutra. Evaluasi dilakukan pada pertumbuhan dan kelangsungan hidup larva ikan patin umur 14 hari. Selama pemeliharaan, larva diberi pakan dengan empat perlakuan; pemberian pakan alami tanpa pakan buatan, pemberian pakan buatan mulai d3, d6, dan d9 dengan tiga ulangan untuk masing-masing perlakuan. Hasil penelitian menunjukkan bahwa perlakuan pemberian pakan buatan mulai d3 memiliki pertumbuhan panjang yang terkecil dibandingkan perlakuan lain, sedangkan tingkat kelangsungan hidup larva tidak berbeda nyata (P>0,05) antarperlakuan. Berdasarkan hasil penelitian, dapat disimpulkan bahwa pakan buatan dapat digunakan sebagai pengganti pakan alami mulai larva ikan patin umur sembilan hari.

ABSTRACT This research was conducted as a preliminary study on utilization of RBO for Nile tilapia (Oreochromis sp.) diet by also evaluating its effect on growth the performance. This research used SULTANA strain at average initial body weights of 8.33±0.07 g/ind. Experimental design was set in completely randomized design. Each treatment was done in triplicates. The treatments were various additions of RBO to replace corn oil in the diet, which were 0%, 25%, 50%, 75%, and 100%. Feeding rate, feed efficiency, protein retention, fat retention, specific growth rate, glucose, cholesterol, triglycerides, HDL (high-density lipoprotein), and hematology were used as evaluating parameters. The results showed that the growth performance, blood chemistry and hematology of fish decreased as the increasing of RBO level in the diet. These are caused by feed intake decreased significantly, which were 583.5 g to 145.6 g of treatments 0% to 100% RBO. Blood glucose, haemoglobin and specific growth of fish in the treatment of 0–100% RBO were 48.7–22.2 mg/dL, 7.6–5.4%, and 3.5–0.8%, respectively. The lowest survival was observed in fish fed 100% RBO (66.7%). Fish growth performance of 0% RBO was the best, so RBO could not be utilized yet as a source of fatty acid or corn oil replacement in tilapia diet. Keywords: free radical, HCN, Oreochromis sp., rubber seed oil ABSTRAK Penelitian ini dilakukan sebagai studi awal pemanfaatan minyak biji karet (MBK) untuk pakan ikan nila dan mengevaluasi pengaruhnya terhadap pertumbuhan ikan nila. Ikan uji yang digunakan adalah ikan nila strain SULTANA dengan bobot awal rata-rata 8,33±0,07 g/ind. Penelitian didesain dalam rancangan acak lengkap (RAL) dengan lima perlakuan dan tiga ulangan. Perlakuan yang diuji berbagai sumbangan MBK untuk mengganti minyak jagung dalam pakan, yaitu 0%, 25%, 50%, 75%, dan 100%. Selama pemeliharaan, beberapa parameter yang diukur adalah jumlah konsumsi pakan, efisiensi pakan, retensi protein, retensi lemak, laju pertumbuhan spesifik, glukosa, kolesterol, trigliserida, high-density lipoprotein (HDL), dan gambaran darah. Hasil penelitian ini menunjukkan bahwa kinerja pertumbuhan, kimia darah dan gambaran darah ikan semakin menurun seiring dengan penambahan MBK dalam pakan. Hal ini disebabkan semakin menurunnya jumlah konsumsi pakan secara signifikan, yaitu 583,5 g menjadi 145,7 g dari perlakuan 0% ke 100% MBK. Glukosa darah, hemoglobin dan laju pertumbuhan spesifik ikan pada perlakuan 0–100% MBK masing-masing adalah 48,7–22,2 mg/dL, 7,6–5,4% dan 3,5–0,8%. Sintasan ikan terendah terjadi pada perlakuan 100% MBK, yaitu 66,7%. Kinerja pertumbuhan pada perlakuan 0% MBK adalah yang paling baik sehingga MBK belum dapat dimanfaatkan sebagai sumber lemak menggantikan minyak jagung pada pakan ikan nila.

ABSTRACT This research was conducted to evaluate the effect of different combination of feeding frequency of Tubifex (C) and artificial diet (P) on survival and growth rate of larval yellow tail catfish Pangasianodon hypophthalmus. Newly hatched larvae (d0) with total length of 0.44±0.04 cm were cultured for 14 days in 30×20×20 cm3 aquarium. Water volume in each aquarium was 9 L. At d5, larvae were fed on five different feeding frequencies either 6C+0PB, 5C+2PB, 3C+3PB, 2C+5PB, dan 0C+6PB. Feeding method used in this research was ad libitum. Results showed that survival and total length of d14 old larvae fed on 0C+6PB was lower than the groups fed on either 6C+0PB or three combinations of C+PB. Lipase activity tend to be increase in line with the increasing amount of artificial feed. On the other hand, larvae fed on 6C+0PB and 0C+6PB had the lowest protease activity. Therefore, larval catfish can be fed by combination of Tubifex and artificial feed. Keywords: artificial diet, lipase activity, protease activity, sludge worm, Pangasianodon hypophthalmus ABSTRAK Penelitian ini mengevaluasi pengaruh perbedaan frekuensi pemberian pakan harian cacing sutra (C) dan pakan buatan (PB) terhadap sintasan dan pertumbuhan larva ikan patin Pangasianodon hypophthalmus. Larva ikan patin yang baru menetas berukuran 0,44±0,04 cm dipelihara dalam akuarium kaca berukuran 30×20×20 cm3 yang diisi air setinggi 15 cm selama 14 hari. Mulai dh5, larva diberi lima perlakuan frekuensi pemberian pakan, yaitu 6C+0PB, 5C+2PB, 3C+3PB, 2C+5PB, dan 0C+6PB. Pemberian pakan dilakukan secara ad libitum. Hasil penelitian menunjukkan bahwa larva yang diberi 6C+0PB dan kombinasi C+PB memiliki tingkat kelangsungan hidup dan panjang akhir yang tidak berbeda nyata. Namun larva yang diberi 0C+6PB, menghasilkan tingkat kelangsungan hidup dan panjang akhirnya terendah. Semakin banyak porsi sering frekuensi pemberian PB yang diberikan menunjukkan tren aktivitas lipase yang cenderung meningkat. Tetapi pada aktivitas protease pada pemberian 6C+0PB dan 0C+6PB lebih rendah dari ketiga perlakuan kombinasi C+PB. Dengan demikian, larva ikan patin dapat dibudidaya dengan menggunakan kombinasi cacing sutra dan pakan buatan.

ABSTRACT The specific activity of the digestive enzymes, namely: pepsin, amylase, lipase, trypsin, and chymotrypsin were studied in Nile tilapia Oreochromis niloticus fed diet supplemented with recombinant Ephinephelus lanceolatus growth hormone (rElGH). The results showed that fish treated with rE1GH showed lower lipase and chymotrypsin specific activities (P>0.05), while the trypsin/chymotrypsin specific activity (T/C ratio) was found higher compared to control fish. Moreover, higher protein digestibility, higher protein retention and a lower ammonia excretion rate were measured for rE1GH treated fish. Oral rElGH administration enhanced Nile tilapia growth up to 20.04%, without affecting survival. This study suggested that rapid growth performance induced by rElGH was linked with T/C ratio rather than the specific activity of other digestive enzymes. Keywords: recombinant growth hormone, digestive enzyme, digestibility, Oreochromis niloticus ABSTRAK Aktivitas spesifik enzim pencernaan pepsin, amilase, lipase, tripsin, dan kemotripsin diamati pada ikan nila Oreochromis niloticus yang diberi pakan mengandung hormon pertumbuhan rekombinan ikan kerapu kertang Ephinephelus lanceolatus (rElGH)). Hasil menunjukkan bahwa ikan uji pada perlakuan rElGH memiliki aktivitas spesifik enzim lipase dan kemotripsin yang lebih rendah, sedangkan rasio tripsin/kemotripsin (rasio T/C) yang lebih tinggi dibandingan ikan kontrol. Kecernaan protein dan retensi protein bernilai lebih tinggi sementara laju ekskresi amonia bernilai lebih rendah pada ikan perlakuan. Pemberian rElGH secara oral mampu mempercepat laju pertumbuhan ikan nila hingga 20,04% tanpa memengaruhi kelangsungan hidup. Berdasarkan penelitian ini, dapat disimpulkan bahwa laju pertumbuhan cepat yang diinduksi oleh rElGH berhubungan dengan rasio T/C dibandingkan dengan aktivitas spesifik enzim pencernaan lain.

ABSTRACT This experiment was conducted to improve the quality of rubber seed meal fermented using sheep rumen liquor based diet (RSMF) with amino acid supplementation for Nile tilapia Oreochromis niloticus. This experiment consisted of five treatments with three replications. The treatments were 0% protein from RSMF as control; 50% RSMF; 50% RSMF with lysine; 75% RSMF and 75% RSMF with lysine. Tilapia with an initial body weight of 6.29±0.12 g were reared for 40 days and the fish were fed three times daily at satiation level (8.00 am, 12.00 pm and 16.00 pm). The data were statistically analysed by using one-way analysis of variance (ANOVA) using software SPSS version 16.0 at 95% (p<0.05) confidence interval and Tukey test for the post hoc test. The results showed that the addition of lysine in the 75% RSMF diets could increased final weight, but did not significantly different to protein efficiency ratio (PER), decreased feed convertion ratio (FCR) and biochemical body composition. The data indicated that quality of 75% RSMF could improved after lysine supplementation, but still lower than using 50% RSMF and soybean meal as protein source. Keywords: amino acid supplementation, Oreochromis niloticus, rubber seed meal ABSTRAK Penelitian ini dilakukan untuk meningkatkan kualitas pakan dengan tepung bungkil biji karet yang difermentasi dengan cairan rumen domba (TBBKF) melalui suplementasi asam amino untuk ikan nila Oreochromis niloticus.
