Abstract

Budidaya bandeng sebagai bahan baku berbagai olahan perlu didukung dengan teknologi yang intensif. Peningkatan kualitas nutrisi bandeng diperlukan untuk memperoleh bahan baku yang tidak hanya banyak tetapi juga bernutrisi. Penambahan probiotik ke dalam pakan bandeng dapat meningkatkan efisiensi pakan agar pakan lebih mudah dicerna dan enzim dapat bekerja lebih efektif. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan probiotik terhadap pertumbuhan, efisiensi pakan, tingkat kelulushidupan dan nilai nutrisi ikan bandeng. Bahan yang digunakan adalah ikan bandeng dengan berat rata-rata 102±2,58 g, pakan bandeng komersil dengan kandungan protein 30% dan probiotik dengan komposisi jamur Saccharomyces cerevisiae, Aspergillus oryzae, bakteri Lactobacillus acidophilus, Bacillus subtilis, Rhodopseudomonas, Actinomycetes dan Nitrobacter. Penelitian dilakukan menggunakan metode eksperimental dengan Rancangan Acak Kelompok dengan dua perlakuan dan 5 kali ulangan. Analisis data menggunakan uji t untuk membandingkan budidaya ikan bandeng perlakuan A yaitu tanpa penggunaan probiotik dalam pakan dan perlakuan B yaitu dengan penggunaan probiotik dalam pakan. Hasil uji t menunjukkan penggunaan probiotik pada pakan berpengaruh nyata (P<0,05) pada pertumbuhan, efisiensi pakan dan nilai nutrisi namun tidak berpengaruh nyata (P>0,05) pada tingkat kelulushidupan ikan bandeng. Penggunaan probiotik pada pakan bandeng memberikan nilai RGR (1.958±0.02%/hari), nilai EPP (78.333±0.745%), kandungan protein (25.794±0.600%) lebih tinggi dan FCR (1.321±0.030) yang lebih baik dari perlakuan tanpa penggunaan probiotik dalam pakan bandeng. Milkfish culture as main raw materia for various processed food needs intensive technology support.

Perlakuan yang diberikan adalah A, B, C, dan D masing-masing ditambahkan dengan tepung cacing tanah 0%, 5%, 10%, dan 15% dari total pakan yang diberikan dalam pakan buatan yang telah difermentasi. Variabel yang diukur adalah PER, SGR, EPP, FCR, dan SR. Hasil penelitian menunjukkan bahwa fermentasi pakan buatan dan penambahan tepung cacing tanah dalam pakan berbentuk pasta berpengaruh nyata (p<0,05) terhadap pertumbuhan (RGR) ,efisiensi pakan (EPP) dan rasio konversi pakan (FCR) namun tidak berpengaruh nyata terhadap kelulushidupan (SR) sidat (A. bicolor) dan kombinasi fermentasi pakan buatan dan penambahan tepung cacing tanah dengan dosis 5% (perlakuan B) memberikan pertumbuhan, efisiensi pakan, dan rasio konversi pakan sidat (A. bicolor) terbaik. Kualitas air pada media pemeliharaan masih pada kondisi layak untuk budidaya sidat. The elver of Anguilla bicolor is the kind of fish that the late growth, due to low in digestability and inefficiency to the feed utilization. One of the solutions to accelerate the growth rate is by adding earthworm powder (Lumbricus sp.) and the fermented artificial feed to improve feed nutrition content so the increasing growth. The obyective of this research was to know the effect of  fermented artificial feed and the addition of earthworm powder in pasta artificial feed on the best of growth, feed utilization, and survival rate of A. bicolor in the culture. Elvers of 320 individuals  with an average weight of 15 ± 1.2 g were cultivated in sixteen of  the  circular aquarium with 80 L in volume. Every aquarium was added 40 L of tap water and weekly aeration with initial density of 20 individuals/aquarium.  Everyday was changed 10 % of tap water and added the pasta artificial feed 5 % of elver body weight for three time feeding habit per day with protein content of  >50%.  The treatments were designed by using a completely randomized design (CRD) with 4 treatments and 4 replicates.  The culture of treatments A was not added  earthworm powder in the fermented pasta artificial feed. Treatments of B, C, and D were added by earthworm powder of 5 %, 10 %, and 15 % in the fermented pasta artificial feed, respectively.  The variables measured were PER, SGR, EPP, FCR, and SR.  The result showed that the artificial feed with different protein levels highly significant influenced (P<0,05) on the RGR, EPP, and FCR, and there was no significant influences (P>0,05) on the SR of elver.  The treatment B (5 % of earthworm) however showed the best one treatment dosage for elvers growth rate than the other treatments. Water quality in culture media was still in decent condition for the cultivation of eels.
