Feed broiler is one important factor that is very supportive of other factors when broiler maintenance. One way to reduce the use of maize is to use alternative raw materials of wheat. Wheat can be obtained and the price is cheaper than corn but contains a high Non Starch Polysaccharide, while the poultry digestive tool is not able to digest such crude fiber because it has no crude fiber-breaking enzymes so it needs enzyme addition to the efficient use of nutrient feed. The research method used is the experimental method using Completely Randomized Design consisting of 4 treatments 5 replications. The treatment is as follows P0 (without wheat and xylanase); P1 (substitution of maize with 20% wheat); P2 (maize substitution with 40% wheat) and P3 (substitution of maize with 60% wheat). The observed variables are metabolic energy of pseudo-feed and metabolically correlated false energy n. Data were analyzed by analysis of variance (ANOVA) if there are differences among the treatments followed by Duncan's Test. The results showed that the use of wheat with a xylanase enzyme supplementation as a substitute corn provides highly significant effect (P<0.01) on the apparent metabolize energy of feed and apparent metabolize energy corrected N. The addition of xylanase enzymes in feed with the substitution of wheat by 20 percent produce the best feed metabolizable energy among other treatments.  Keywords : Broiler, Wheat, Enzymes, Energy, Feed

Not infectious disease (PTM) have become a health problem for every country. One of the main contributors who use PTM is food control, by consuming foods that contain inulin (bengkuang tubers) and anthocyanins (dragon fruit). Intermittent food products consisting of velva become more effective because in one product already has a lot of special nutritional content of inulin and anthocyanin fibers. The design of this study was experimental with a completely randomized design (CRD). The research method uses hedonic tests, spectrophotometry for anthocyanin levels, and literature tests for inulin fiber levels. This study involved 30 panelists who were apparently students of the Nutrition Department of the Poltekkes Bandung. This product formulation consists of three dragons and bengkuang, which is counterpart 1 (30%: 70%), counterpart 2 (70%: 30%), and counterpart 3 (50%: 50%). The hedonic test results showed that the level of preference consisted of counterpart 2 and the Kruskal-Wallis test results showed differences between the aspects of color, taste, and aroma with a value of p <α and also none in the design of the texture with p> α. The level of anthocyanin product serving is 6.04 mg and can fulfill 81% of the anthocyanin requirement by consuming two serving sizes. While the level of inulin per serving amounted to 2.1 g and can meet the needs of inulin at least a day from 350% snack.

The number of studies on edible coatings that are used for extending the shelf life of fruits has steadily increased. For this purpose, it is necessary to choose raw materials with characteristics that maintain product quality. The objective of this study is to evaluate the effect of coatings of Chlorella sp. on the post-harvest conservation of ‘Tommy Atkins’ mango fruits. The experiment was conducted using a completely randomized design, and spray treatments (T) with 0%, 1%, 2%, 3%, or 4% of Chlorella sp. were applied to the fruits. After the treatments, the fruits were stored for 28 days (21 days at 10 °C and 42% relative humidity and 7 days at 25 °C and 42% relative humidity), and were analyzed on day 28. There was higher pulp firmness in fruits as the concentration of Chlorella sp. was increased, and the concentration of ascorbic acid was comparatively higher (22.17%) in fruits treated with 3% Chlorella sp. The percentage of soluble solids and the soluble solids/titratable acidity ratio were decreased as the coating concentrations were decreased. The use of Chlorella sp. at 1% and 2% allowed fruit maturation without compromising fruit quality attributes during the 28-day storage period.

Abstract Liquid smoke has many benefits, especially in the food, fishery, timber, and plantation industries. It is used as a preservative or durability increased and aroma and taste addition in the food and fishery industry. In the wood industry, liquid smoke can resist termite attacks, while in the plantation industry, it functions as a latex coagulant containing antifungal, antibacterial, and antioxidants that can improve rubber product’s quality. Most of the rubber farmers in Bangka Belitung still use alum as a coagulant to coagulate their latex. However, alum coagulant can reduce the quality of the processed rubber material (bokar). The reason farmers use alum is that raw materials are cheap, therefore getting coagulant raw materials at low prices and not pollute the environment with a less moderate aroma/odor caused by non-recommended coagulant materials (alum) are needed. This study aims to apply liquid smoke as a natural coagulant in latex freezing. The research method used a Completely Randomized Design, with liquid smoke concentration replicated three times. Parameters observed were clotting time speed and organoleptic test for odor during 14 days of storage. The results showed that the best concentration of liquid smoke was 15% no odor and a clotting time of 8.23 minutes.
