Abstract

Probiotics are living microbial agents that can provide benefits to the host by modifying the microbial community or associating with the host, improving the nutritional value and utilization of feed, increasing the host's response to disease, and improving the quality of its threshold environment. This study was conducted to determine the effect of probiotic application in manufactured feed on feed consumption, feed utilization efficiency, growth rate and survival rate of tilapia (Oreochromis, sp). The study used a Completely Randomized Design method with five treatments and four replications. Treatment A is feed without the addition of probiotics; treatment B is feed with the addition of 5 cc/kg of probiotics; treatment C is feed with the addition of 10 cc/kg of probiotics, treatment D is feed with the addition of 15 cc/kg of probiotics and treatment E is feed with the addition of 20 cc/kg of probiotics. The variables observed in this study were feed consumption, feed utilization efficiency, relative growth rate and survival rate of tilapia (Oreochromis, sp). The results of the study showed that the treatment of feeding with the addition of probiotics had a very significant effect (p <0.05). The best treatment was treatment C, namely feed with the addition of 10gr/kg of probiotics. While water quality data and other supporting data were analyzed descriptively. The results showed that the treatment of feed with the addition of 10cc/kg of probiotics showed the best results on feed consumption, feed utilization efficiency and relative growth rate. KINERJA PERTUMBUHAN IKAN NILA YANG DIBERI PAKAN DENGAN PENAMBAHAN DOSIS PROBIOTIK YANG BERBEDAProbiotik merupakan agen mikroba hidup yang mampu memberikan keuntungan bagi inang dengan memodifikasi komunitas mikroba atau berasosiasi dengan inang, memperbaiki nilai nutrisi dan pemanfaatan pakan, meningkatkan respon inang terhadap penyakit,dan memperbaiki kualitas lingkungan ambangnya. Penelitian ini dilakukan untuk mengetahui pengaruh aplikasi probiotik pada pakan pabrikan terhadap konsumsi pakan, efisiensi pemanfaatan pakan, laju pertumbuhan dan kelangsungan  hidup/survival rate ikan nila (Oreochromis, sp). Penelitian  menggunakan  metode Rancangan Acak Lengkap dengan lima perlakuan dan empat kali ulangan. Perlakuan A adalah pakan  tanpa penambahan probiotik; perlakuan B adalah pakan dengan penambahan probiotik 5 cc/kg pakan; perlakuan C adalah pakan dengan penambahan probiotik 10 cc/kg pakan, perlakuan D adalah pakan dengan penambahan probiotik 15 cc/kg pakan dan perlakuan  E adalah pakan dengan  penambahan  probiotik 20 cc/kg pakan. Peubah yang diamati dalam penelitan ini adalah konsumsi pakan, efisiensi pemanfaatan pakan,laju pertumbuhan relative dan kelangsungan hidup ikan nila(Oreochromis,sp).Hasil penelitian  menunjukkan bahwa perlakuan pemberian pakan dengan penambahan probiotik  berpengaruh sangat nyata (p< 0,05). Perlakuan terbaik adalah perlakuan C yaitu pakan dengan penambahan  probiotik 10gr/kg pakan, sedangkan  data  kualitas air dan data penunjang yang lain dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa perlakuan pakan dengan penambahan probiotik 10cc/kg pakan  menunjukkan hasil yang terbaik terhadap konsumsi pakan ,efisiensi pemanfaatan pakan dan laju pertumbuhan relative.

Abstract

Ikan gurame adalah komoditas budidaya ikan air tawar dengan pertumbuhan lambat namun bernilai ekonomis tinggi. Pakan merupakan faktor utama yang menentukan pertumbuhan dan daya tahan ikan terhadap penyakit. Inovasi dalam pakan diperlukan untuk meningkatkan pertumbuhan ikan gurame, salah satunya dengan penambahan tepung biji turi yang difermentasi. Biji turi adalah bahan baku lokal yang kaya protein (36,21%) dan Vitamin B2 (Riboflavin), yang baik untuk kesehatan saluran pencernaan dan antioksidan. Namun, biji turi mengandung serat kasar tinggi (12,54%). Penelitian ini bertujuan untuk mengetahui pengaruh fermentasi tepung biji turi pada pakan buatan terhadap pertumbuhan dan sintasan ikan gurame serta dosis optimal yang ditambahkan. Benih ikan gurame dengan bobot rata-rata 4 g dan padat tebar 1 ekor/l air digunakan dalam rancangan acak lengkap dengan 4 perlakuan dan 3 ulangan, yaitu perlakuan A kontrol (0 g/1000 g pakan), B (10 g/1000 g pakan), C (20 g/1000 g pakan), dan D (30 g/1000 g pakan). Hasil penelitian menunjukan penambahan fermentasi tepung biji turi pada pakan buatan berpengaruh terhadap pertumbuhan mutlak, laju pertumbuhan relatif (RGR), rasio konversi pakan (FCR), efisiensi pemanfaatan pakan (EPP) benih ikan gurame. Dosis optimal fermentasi tepung biji turi adalah 30g/kg (Perlakuan D) dalam pakan buatan mampu menghasilkan pertumbuhan mutlak 46,05 g, laju pertumbuhan relatif (RGR) 4,45 %, rasio konversi pakan (FCR) 1,75, efisiensi pemanfaatan pakan (EPP) 63,22 % dan tingkat kelulushidupan (SR) 100%. EFFECTS OF FERMENTED TURI SEED MEAL SUPPLEMENTATION ON GROWTH AND SURVIVAL RATES OF GOURAMI FRY (Osphronemus gouramy Lac.)Gourami fish is a freshwater aquaculture commodity with slow growth but high economic value. Feed is the main factor determining the growth and disease resistance of the fish. Innovation in feed is necessary to improve the growth of gourami, one of which is by adding fermented turi seed flour. Turi seeds are a local raw material rich in protein (36.21%) and Vitamin B2 (Riboflavin), which are beneficial for digestive health and act as antioxidants. However, turi seeds contain high crude fiber (12.54%). This study aims to determine the effect of fermented turi seed flour in artificial feed on the growth and survival rate of gourami and to identify the optimal dosage to be added. Gourami fry with an average weight of 4 g and a stocking density of 1 fish/liter of water were used in a completely randomized design with 4 treatments and 3 replications: treatment A (control, 0 g/1000 g feed), B (10 g/1000 g feed), C (20 g/1000 g feed), and D (30 g/1000 g feed). The results showed that the addition of fermented turi seed flour to artificial feed affected the absolute growth, relative growth rate (RGR), feed conversion ratio (FCR), and feed utilization efficiency (EPP) of gourami fry. The optimal dosage of fermented turi seed flour was 30 g/kg (Treatment D) in artificial feed, which resulted in an absolute growth of 46.05 g, a relative growth rate (RGR) of 4.45%, a feed conversion ratio (FCR) of 1.75, feed utilization efficiency (EPP) of 63.22%, and a survival rate (SR) of 100%.
