Respon Imun Larva Udang Vanamei (Litopenaeus vannamei) dengan Bioenkapsulasi Vitamin C pada Artemia salina
No full textThe low quality of vannamei shrimp seeds during larval rearing causes vannamei shrimp seeds to be more susceptible to disease, thus affecting production success. This situation can be overcome by increasing the immune response of vanamei larvae through the administration of vitamin C. This study aims to evaluate the effectiveness of Artemia salina bio encapsulation with vitamin C to increase immunity against vibriosis disease of vannamei shrimp larvae. The treatment tried was the addition of vitamin C through A. salina bio encapsulation with four different doses, 20, 30, 40, and 50 ppm as well as control (without vitamin C), each with three replicates using a Completely Randomized Design (CRD). Vaname shrimp seeds were reared from Mysis-PL11 stadia in 50-liter capacity crates, 40-liter volume of media water with a density of 40 fish/liter, then checked Total hemocyte count (THC), Differential hemocyte count (DHC) before and after the challenge test was carried out by using Vibrio harveyii bacteria. The results showed that the effectiveness of the immunostimulant vitamin C through A. salina bio encapsulation to prevent vibriosis had a significant effect on the immune system of Mysis-PL11 stadia vannamei shrimp larvae with the highest THC value of 41 x 104 cells/mm, DHC (66.67% hyaline, 27 .67% semi-granular, 67.67% granular) in the treatment with the addition of 50 ppm vitamin C.Rendahnya mutu benih udang vaname selama pemeliharaan larva menyebabkan benih udang vaname lebih rentan terhadap penyakit sehingga mempengaruhi keberhasilan produksi.

No full textThis study aims to determine the effect of supplementation with Moringa oleifera leaf flour as a source of carotenoids on the level of color brightness, growth rate, and survival of koi fish seeds (Cyprinus rubrofuscus). The research design was a Completely Randomized Design (CRD), with 4 treatments and 3 replications. Treatments A (without Moringa leaf flour supplementation), B (100 grams Moringa leaf flour supplementation/kg feed), C (200 grams Moringa leaf flour supplementation/kg feed), and D (300 grams Moringa leaf flour supplementation/kg feed). The results of the study showed that supplementation with Moringa leaf flour as a source of carotenoids in feed, although it did not (yet) have a significant effect on the color brightness of koi fish seeds (P>0.05) because the dose given was thought to be still insufficient, had a significant effect on absolute growth and survival to Koi fish seeds (P<0.05). It can be concluded that Moringa leaf flour can be used as an alternative supplement source of carotenoids to increase the brightness of koi fish color. However, the correct and optimal dosage still needs further research

No full textThis present study investigates the combination of probiotic Lactobacillus sp. and molasses applied to promote growth performance and survival of Nile Tilapia seed. Probiotic could act as an additive agent for fish seed with incomplete digestive organ development as it produces the digestion-support enzyme. The experiment was set based on the formalized fish feed, consisting of A (no molasses and probiotic provision), B (2 r/L molasses), C (108 cfu/mL probiotic), D (108 cfu/mL probiotic + 4 r/L molasses), E (1010 cfu/mL probiotic + 2 r/L molasses) and applied in three replicates each. Fish were reared in cone bottom tanks and were fed according to the treatment (2 times a day in 3 weeks). The growth and survival rate data were collected during the experiment and were analyzed using ANOVA (analysis of variance). The results indicate significant growth and survival of Nile Tilapia seed (P<0,05) generated by the enhancement of probiotics and molasses into fish feed with formalized 1010 cfu/mL probiotic + 2 r/L molasses.Ikan nila adalah salah satu jenis ikan air tawar yang banyak digemari oleh masyarakat karena rasanya yang enak dengan harga yang ekonomis. Hal tersebut membuat permintaan benih ikan nila untuk dibudidayakan cukup tinggi, akan tetapi produksi benih masih terbatas karena berbagai faktor seperti pakan, kualitas air, teknologi dan lain sebagainya. Dilakukan pengembangan teknologi melalui pakan ikan dengan pemberian probiotik dan molase dengan dosis yang berbeda untuk melihat pengaruhnya pada pertumbuhan dan kelangsungan hidup benih ikan nila. Probiotik yang diberikan dapat memberikan efek positif terhadap organisme yang mengkonsumsinya, karena probiotik mengandung enzim yang dapat membantu ikan dalam mencerna pakan yang diberikan khususnya pada stadia benih karena organ pencernaan ikan masih belum sempurna. Metode pemberian pakan dilakukan dengan cara menambahkan probiotik dan molase ke dalam pakan ikan dengan lima jenis perlakuan masing-masing tiga ulangan yaitu A : (pakan murni), B : (molase 2 gr/L), C : (probiotik108 cfu/mL), D : (probiotik 108 cfu/mL + molase 4 gr/L), E : (probiotik 1010 cfu/mL + molase 2 gr/L). Data kemudian dianalisis menggunakan analisis ragam Anova. Hasil uji data menunjukkan bahwa pemberian probiotik dan molase memberikan pengaruh yang signifikan terhadap pertumbuhan dan kelangsungan hidup benih ikan nila (P<0,05).

Pertumbuhan Stek Bibit Tanaman Sukun (Artocarpus altilis) dengan Pemberian Pupuk Organik dan Plant Growth Promoting Rhizobacteria (PGPR) dari Akar Bambu
No full textThe breadfruit plant (Artocarpus altilis) can be cultivated as a staple food to accompany rice to support the diversification of food consumption found in many regions in Indonesia. Apart from being a food-producing plant, breadfruit plants act as pioneering plants for reforestation, land conservation, and medicinal plants. The research aims to determine the effect of goat drum fertilizer and PGPR on the growth of breadfruit plant seed cuttings. The research used a Randomized Block Design (RAK) with a factorial analysis of two factors and three replications. The first factor is the dose of goat manure, which consists of 4 levels: control (without fertilizer), 100g polybag-1, 200g polybag-1, and 300g polybag-1. The second factor is the PGPR concentration from bamboo roots, which consists of 4 levels: control (without PGPR), 115ml L-1, 125ml L-1, and 135ml L-1. The research results show that using a 300g polybag-1 dose of goat drum fertilizer has a natural effect and tends to be better on the parameters of shoot emergence time, shoot length, number of leaves, and root length. Meanwhile, the PGPR concentration of bamboo roots at a concentration of 135mlL-1 significantly affected all parameters measured. The interaction between the dose of goat drum fertilizer and the PGPR concentration of bamboo roots had no significant effect on the growth of breadfruit plant root cuttings
