Abstract

upaya untuk mengurangi kadar lemak tersebut. Tujuan penelitian ini adalah mengevaluasi suplementasi L-karnitin dan tepung kayu manis terhadap kadar lemak dan tekstur daging ikan patin pada fase pembesaran. Ikan patin berukuran 125,4 ± 7,85 g dan panjang 24,71±0,68 cm dipelihara selama 60 hari dalam wadah hapa berukuran 2 x 1 x 1 m3. Ikan diberi pakan tiga kali sehari ad satiation dengan perlakuan, sebagai berikut: kontrol (K), penambahan L-karnitin 1 g kg-1 (LK 1), L-karnitin 2 g kg-1 (LK 2), kayu manis 5 g kg-1 (KM 5), dan kayu manis 10 g kg-1 (KM 10). Sampel diambil pada awal, pertengahan, dan akhir pemeliharaan untuk pengukuran kadar lemak daging. Parameter yang diamati yaitu lemak daging dan tekstur daging. Hasil menunjukkan bahwa pemberian KM 10 menghasilkan kadar lemak yang lebih rendah dari perlakuan lainnya setelah 30 hari dan penurunan yang lebih besar yaitu berkisar 51,06% dan 42,55% pada perlakuan LK 2 dan KM 10 pada hari ke-60. Nilai indeks hepatosomatik juga menurun yang diikuti oleh penurunan kadar lemak hati. Nilai kekerasan daging menunjukkan peningkatan kualitas yang terlihat dari nilai yang semakin rendah. Pemberian tepung kayu manis 10 g kg-1 pada fase pembesaran menunjukkan hasil terbaik pada pemberian selama 60 hari dalam menurunkan lemak daging ikan patin hingga memenuhi standar filet, karena adanya proses lipolisis serta pemanfaatan lemak menjadi energi. Kayu manis ini menjadi sangat potensial untuk dikembangkan sebagai feed additive dalam upaya memperbaiki kualitas daging ikan patin fase pembesaran.Striped catfish meat has a high-fat content which is undesirable to markets and customers alike and needs to be reduced. This study aims to evaluate the effect of dietary L-carnitine and cinnamon powder on reducing the fat content of striped catfish meat in the grow-out stage. Striped catfish measuring 125.4 ± 7.85 g and 24.71 ± 0.68 cm body length were kept for 60 days in a hapa with size 2 x 1 x 1 m3. Thefish were fed three times a day at satiation with the following treatments: control (K), the addition of L-carnitine 1 g kg-1 (LK 1), L-carnitine 2 g kg-1 (LK 2), cinnamon 5 g kg-1 (KM 5) and cinnamon 10 g kg-1 (KM 10). Sampling was conducted on the initial, middle and final day for meat fat content analysis. The parameters observed were meat fat and meat texture. The results showed that dietary KM 10 significantly reduced meat fat content compared to controls on the 30th and it showed a more significant reduction, namely 51.06% and 42.55%, in the treatment LK 2 and KM 10 after 60 days treatment. The hepatosomatic index value also decreased, followed by decreased liver fat levels. The lower values of meat hardness imply an increase in meat quality. It can be concluded that the application of dietary cinnamon powder at 10 g kg-1 (KM 10) is the best level to reduce the fat content of striped catfish meat in meeting the fillet standards. This cinnamon has excellent potential to be developed as a feed additive to improve the quality of striped catfish meat in the rearing phase.

Abstract

Biomassa bioflok dalam sistem pemeliharaan ikan dapat dimanfaatkan menjadi pakan alami tambahan bagi ikan. Penelitian ini bertujuan untuk mengevaluasi kinerja pertumbuhan ikan lele Clarias gariepinus yang dipelihara menggunakan teknologi bioflok dengan tingkat pemberian pakan berbeda. Perlakuan terdiri dari tiga tingkat pemberian pakan, yaitu 5% (FR5), 3,75% (FR3,75), dan 2,5% (FR2,5). Benih ikan lele dengan panjang awal 11,92 ± 0,03 cm dan bobot awal 11,31 ± 0,11 g dipelihara dengan padat tebar 25 ekor per akuarium (500 ekor m-3) selama 42 hari. Ulangan biologis tiap perlakuan berupa 3 unit akuarium (volume air 50 L). Ikan diberi pakan 3 kali setiap hari dengan jumlah pakan sesuai perlakuan. Penambahan tepung tapioka dilakukan setiap hari untuk mencapai rasio C/N 10. Hasil penelitian menunjukkan bobot akhir menurun seiring penurunan tingkat pemberian pakan (P<0,05), seperti ditunjukkan pula laju pertumbuhan spesifik. Terdapat indikasi kontribusi bioflok terhadap kinerja pertumbuhan ikan lele berdasarkan nilai efisiensi pemanfaatan pakan dan retensi protein. Akan tetapi, tidak dapat menggantikan peran pakan eksternal. Tingkat pemberian pakan berpengaruh terhadap kinerja pertumbuhan ikan lele pada sistem bioflok.Biofloc biomass could be used as additional natural food for fish in a biofloc-based fish culture system. This study aimed to evaluate the growth performance of African catfish, Clarias gariepinus cultured in a biofloc system fed at different feeding levels. The treatments consisted of three feeding levels; 5% (FR5), 3,75% (FR3,75), and 2,5% (FR2,5). Catfish juveniles with an initial average body length of 11,92 ± 0,03 cm and average body weight of 11,31 ± 0,11 g were reared at a density of 25 fish per aquarium (500 fish m-3) for 42 days. Each treatment had three unit aquaria (50 L water volume) as replicates. Cassava meal was added daily to reach C/N ratio of 10. The results showed that the fish’s final weight and specific growth rate were reduced, corresponding to the feeding rate. There was an indication that biofloc contributes to the fish growth performance based on the feed efficiency and protein retention level. However, biofloc could not replace the role of external feed to support the growth of African catfish.

Abstract

Plankton plays an important role in shrimp cultivation in ponds, both as an indicator of water quality and as a natural food source for shrimp that are raised. The purpose of this study was to measure the relationship between the dynamics of the plankton community, the concentration of total organic matter, and water salinity with the abundance of plankton in intensive shrimp farming systems. The study was conducted on six units of ponds located in Cirebon district, West Java, Indonesia. The ponds were lined with HDPE on each side and plastic mulch at the bottom. Post larvae of shrimp were stocked at an average density of 110 shrimp.m-2 and maintained for 98 days. Water quality samples were collected for daily measurement. Data were analyzed descriptively and then analyzed using Pearson's correlation test and regression. The results of this study showed that during the shrimp rearing period, 65 species of plankton were identified, consisting of Chlorophyta 20%, Cyanophyta 15.38%, Diatoms 26.15%, Euglenophyta 6.15%, Dinoflagellates 4.62%, Protozoa 10.77%, and Ciliates 16.92% with an average density ranging from 7.56x105-19.99x105 cells.mL-1. Chlorella sp. (Chlorophyta) and Oscillatoria sp. (Cyanophyta) were found to be the dominating species in all ponds. Total phytoplankton density tended to be higher during the first 54 days of culture. The results of the correlation and regression tests showed that the composition of plankton, the concentration of total organic matter, and the salinity of the water affected the abundance of plankton in the pond.
