Abstract

Kefir is a fermented milk product made by inoculating milk with kefir grains, a combination of bacteria and yeast. These microorganisms will play a role in the fermentation of lactic acid and alcohol, which can provide a therapeutic effect. The presence of probiotics in feed can increase enzymatic and digestive activity. As a natural probiotic, Kefir contains various strains of bacteria and yeast that can be used as a substitute for antibiotics that are limited in their use nowadays. The effectiveness of kefir as a probiotic was studied on the production, feed efficiency, and relative weight of the digestive tract in broiler chickens. This study used DOC broiler strain MB 202 with as many as 200 unsexing using a completely random design with four treatments and five replicates for five weeks. Treatment consisted of T0 = basal ration (control), T1 = basal ration + 1.5% probiotic kefir, T2 = basal ration + 3% probiotic kefir, T3 = basal ration+ 4.5% probiotic kefir. The kefir used comes from goat's milk which was given as much as 10% grain kefir fermented for 48 hours. The ANOVA resulted from a real difference (P<0.05) in performance for each treatment compared to the control. At the same time, the intestinal weight parameters of the digestive tract did not show a real difference (P>0.05). The addition of 4.5% probiotic kefir showed the best results on four performance parameters, including consumption, weight gain, and feed conversion ratio, which is also supported by the highest carcass yield compared to other treatments.

Abstract

This 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.

Abstract

The 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.

Abstract

Sunflower is one of the oil-producing plants with great potential to be developed as food raw materials, industrial materials, medicinal and beauty ingredients. Sunflower development needs to be carried out on various lands in Indonesia. One of them is in the coastal area. However, these lands are marginal lands so improvements need to be made through various technological innovations. One of them is the application of mycorrhizae and chicken manure fertilizer. This study aims to determine the effect of mycorrhizae and chicken manure on sunflower growth on coastal land. This research was conducted using a randomized block design consisting of two factors, namely mycorrhizae and chicken manure, which were repeated 3 times. The results of the study showed that the application of mycorrhizal and chicken manure fertilizers increased the percentage of seedlings growing, plant height, leaf number, and stem diameter of sunflowers on coastal land.

Abstract

Provisions regarding coffee exports have been regulated several times by Regulation of the Minister of Trade of the Republic of Indonesia until the most recent is Permendag No. 19 of 2021. Since the enactment of this regulation, all coffee business actors have had the opportunity to become Indonesian coffee exporters. This study discusses whether there has been a change in the value of coffee exports before and after Permendag No.19 of 2021 on coffee exports in Indonesia. The research methodology used is quantitative descriptive, using secondary data, which is analyzed using the Paired sample T-test to determine the difference in the average coffee export value before and after Permendag No.19 of 2021. The results show that the Government of Trade No.19 of 2021 influences Indonesian coffee exports. The value of Indonesian coffee exports after the implementation of Permendag No. 19 of 2019 has increased, which is relatively high, as seen from the correlation value, which reaches 96%. The ease of exporting coffee products after the Minister of Trade Regulation is one of the reasons. Permendag No.19 of 2021 in article 50 point (r) makes the coffee export process more accessible so that in addition to reaching a broader market, it also increases the emergence of new exporters. It allows coffee from upstream or farmers to directly access the international market.
