This research was aimed to study of palatability and body weight gain local sheeps given minerals herbal (MBH). The farms used in this study were male 4 local sheep at the age of 12-18 months who showed symptoms of mineral deficiency. The research method used is the Latin Square Design (LSD). The treatment given is: H0 = Basal Feed + Salt; H1 = Basal Feed + Salt + Mineral + Turmeric; H2 = Basal Feed + Salt + Mineral + Ginger; H3 = Basal Feed + Salt + Mineral + Turmeric + Ginger. The research parameter is the mineral palatability of herbal blocks and body weight gain. The results showed that MBH given turmeric (10%), ginger (10%) and a combination of 5% + 5% ginger showed a non-significant effect on feed consumption and conversion. Palatability test showed that all MBH treatments were favored by local sheep, but the highest palatability of MBH was by adding ginger; followed by a combination of ginger and turmeric; and the lowest palatability is turmeric. Based on palatability tests, MBH with turmeric supplementation of 10%; 10% ginger or a combination of 5% ginger + 5% turmeric in the form of Herbal Minerals Block has a good palatability (preferred) and can improve the performance of local sheep.

The aim of this study was to determine the suitable Moringa oleifera leaf added for steamed sponge production, which was made from the mixture of wheat and banana flours. This research was conducted. This research was conducted by using completely randomized design with 2-factors, namely percentage of moringa leaf flour (K): (0,0% ; 1,0% ; 2,0%) and comparison of mixture wheat flour and banana flour (P): (100%:0% ; 75%:25% ; 50%:50% ; 25%:75%). The results showed that the addition of more moringa leaf flour increased the ash, protein and crude fiber contents in the composite flours. The increment might be related to higher ash, protein and fiber contents in moringa leaf flour than that of in both wheat flour and banana flour. In addition, higher banana flour substitution raised the moisture and ash contents. Meanwhile, the specific volume of cake decreased because banana flour does not have gluten. Based on the protein content and organoleptic values, the addition of 2% moringa leaf flour and the ratio of wheat flour to banana flour (75%:25%) produced the best quality of steamed sponge cake.

Quail is one of the potential sources of animal protein from poultry as egg producers. An egg contains complete nutrients, namely protein, fat, vitamins, and minerals. As food, eggs must be maintained both physically and chemically to be safe for consumption. This study aimeds to examine the effect of selective feeding on the quality of quail eggs. This research was carried out at Percut Sei Tuan Subdistrict, Deli Serdang Regency, North Sumatra, which had been implemented from August to November in 2018. The study used a completely randomized design with 4 treatments and 5 plots. The study used egg samples from quail aged five (5) months. The treatment consists of Commercial feed (T0), 2 energy source feed (rice bran, corn) with 2 (T1), 3 (T2), 4 (T3) protein source feeds (fish meal, soybean meal, coconut meal, Poultry Meat Meal). The results showed that the treatment gave a significant effect (P<0.05) on egg weight, albumen, and eggshell weight, commercial feed showed eggs weight higher than free choice feeding treatments, while among free choice feeding treatment did not show significant effect. The free choice feeding treatment has a significant effect on the yolk weight, where T2 has the lowest yield. Percentage of yolk, albumen, quail eggshell and egg index, egg yolk index, albumen index, haugh unit and quail yolk color did not show significantly different (P>0.05) among treatment. It can be concluded that the commercial feed showed higher egg weight but had no significant effect (P>0.05) on the proportion of eggs and the interior quality of quail eggs, while among free choicee feeding treatment has no effect.

This research study has reported different profit margin of smallholders in Labuhan Batu and Asahan which can be due to productionâ€™s cost incurred by smallholders. In addition, the price of fresh fruit bunches (FFB) of oil palm offered by eachtrader is also found different. This could be the differences in efficiency and the length of marketing channels traversed by partner and non-partner samllholders. The length of marketing chain was transferred to the marketing costs incurred and the margins received, so there is share for each marketing. Therefore such study is needed to estimate the marketing margins and channels of non-partner smallholders, partner smallholders, and explasma smallholders, the marketing functions carried out by each palm oil marketing channel in Kuala Hulu, factors that help samllholders choose marketing channels, increase marketing and the efficientcy of non-partner samllholders, partner smallholders, and explasma smallholders. The data used in this study are primary as well as secondary data. The analytical method used in the Shepperdâ€™s Method, Acharya and Anggarwalâ€™s Method, Composite Index Method, Marketing efficiency index method and Soekartawi Method. The analysis shows that there are 2 marketing channels, identified as Channel 1 : Smallholders-Middleman_RAM-Palm Oil Mill and Channel 2 : Smallholders-Middleman-Palm Oil Mill. The study has concluded that all smallholders do selling, transporting, standardization, risk bearing, and securing market information. Regular customer, services, contracts are figured out as the major reasons marketing agents choose marketing channels. The most efficient marketing channel is partner independent samllholders with the shortest channel.

The study was design to evaluate the antioxidant and anti-inflammatory effect of snack bars that made of black glutinous rice and pumpkin powder and study on the male Sprague Dawley rats. Twenty-five male rats in between the age of 2 and 3 months were selected and randomly divided into 5 groups, which were positive control, negative control, group with sylimarin treatment, snack bars A and snack bars B. Carbon tetrachloride was used to induce hepatic damage. The results showed that group with CCl4 treatment has 3.04 Â± 0.16 Î¼mol/L MDA while group with Sylimarin, snack bars A, snack bars B were 0.49 Â± 0.05; 0.54 Â± 0.05; and 1.15 Â± 0.16 Î¼mol/L MDA, respectively. The snack bars had the capacity to decline the damage in liver as much as Sylimarin (standardized natural medicine for hepatotoxicity). The SGPT (Serum Glutamin Pyruvic Transaminase) of the two treatment was 22.24 Â± 0.80 U/I for Sylimarin and 22.33 Â± 1.03 U/I for snack bars while SGOT (Serum Glutamic Oxaloacetic Transaminase) was 40.78 Â± 0.77 U/I for Sylimarin and 40.88 Â± 1.25 U/I for snack bars A. Snack bars B has a significantly different value on final SGOT and SGPT.

Streptomyces sp. bacteria have the potential to produce antibiotic compounds, which are one of the mechanisms that are widely used in biological control. However, in general, biological control mechanisms also occur through competition, cell wall degradation and induced resistance. This study was aimed to determine the physiological, biochemical and molecular characteristics of two isolates of Streptomyces sp. (S-4 and S16 isolates) isolated from the tomatoes roots, and to find out their ability to control Ralstonia solanacearum, which causes bacterial wilt disease on a wide range of hosts. The results showed both Streptomyces sp. isolates had several different physiological and biochemical characteristics and had a different ability to inhibit R. solanacearum in vitro. Streptomyces sp. S-16 isolate had a high similarity with Streptomyces diastaticus subsp. ardesiacus strain NRRL B-1773T based on the molecular identification results. Further research needs to be done to see the potential inhibition of the two Streptomyces isolates in inhibiting the development of bacterial wilt disease in tomato plants caused by R. solanacearum.
