Abstract

Corn waste is an agricultural product that has the potential to be used as animal feed. The aims of this study was to isolate corn waste bacteria and look for the degradation ability of bacterial fiber of corn waste as a fibrous feed bioactivator. This study was conducted in livestock production laboratory of livestock study program in faculty of agriculture, university of north Sumatra, period March to June 2018. This study used corn waste (corncob, corn straw, corn clobot, corn stalks, and corn root). Research methods used pour plate isolate methods. Parameters observed are macroscopic morphology (colony form, colony color, the edge of the colony , and colony elevesi), microscopic morphology (cell shape and gram coloring), and test the ability to degrade fiber in bacteria.  The isolation result obtained 8 isolates with varied shapes and there are 6 isolates that have ability to degrade fibers in bacteria include B2, B3, B4, B5, B6, B7. The conclusion of this study were obtained 8 cellulolytic bacteria isolates and B3 has a high potential to degrade the fiber.

Abstract

Rabbits are livestock that can be used as a source of animal protein and have the potential to have meet national meat needs. Further development is needed whit good quality feed and affordable prices. The study aimed to evaluate feed containing corn cobs which were fermented by MOIYL against carcasses in local rabbits. The study was conducted in Bandar Klippa Deli Serdang Village, North Sumatra Province, in January - March 2018. This study used 20 local rabbits with initial weights of 404.4 ± 9.14 grams and experimental designs using a completely randomized design (CDR), which consisted from 4 treatments and five replications. The treatment consisted of P0 = unfermented ration, P1 = 10%, P2 = 20%, and P3 = 30%. The variables measured were cut weight, carcass weight, and carcass percentage. The results showed that corn cobs fermentation with probiotics MOIYL had a significant effect (P <0.01) and not significant (P> 0.05), increasing corn cobs fermented by MOIYL to a level of 30% increasing slaughter weight and carcass weight, but does not increase the percentage of carcass.

Abstract

Post harvest quality of cow meat and in storage may changes as consequence of biochemistry and microbiology process. This changes make meat durability and processed products will be limited. So that necessary processing to improve meat durability is needed. This study aimed to test the effect of soaking time of liquid smoke against meat durability meet by tenderness and organoleptic test(texture, aroma, flavor and tenderness). This research was conducted  at Laboratory of Food Technology Faculty of Agriculture, University of North Sumatra from Mei to June 2016.The design used in this study was completely randomized factorial design (factorial CRD) using two factors:the soaking time of liquid smoke(A): (5 minutes, 10 minutes and15minutes) and storability(P): (1 week, 2weeks, 3 weeks and4 weeks). The parameters analyzed were cooking shrinkage, tenderness and organoleptic test(texture, aroma, and flavor). The results showed that soaking time of liquid smoke gave highly significant effect (P<0,01) to the organoleptic test (aroma), while storability give highly significant effect (P<0,01) to the cooking shrinkage(%), tenderness, andorganoleptic test(texture, aroma, and flavor).The best results were obtained ats oaking time of liquid smoke 15 minutes

The variablesobserved were plant height, number of leaves, number of stems, stem diameter and leafwidth. The results showed that the application of manure from goats had a significanteffect on the parameters of the study, namely plant height, number of leaves, number ofbranches and stem diameter. In conclusion, the increasing dosage of fertilization withgoat manure on Indigofera zollingeriana plants, the results are getting better.

Abstract

Cassava peel was the waste of processing cassava which is promising enough to be used as alternative animal feed. However, cassava peel has a fairly low nutrient content. Fermentation was one of the way to increase the quality of cassava peel. Fermentation used in this research utilized Indigenous Microorganisms (IMO) with the main substance was the cassava peel itself. This research lasted for 3 months started from December 2018 to February 2019 at the Laboratory of Microbiology and Laboratory of Feed Processing Science and Technology Department of Animal Science Faculty of Agriculture University of Sumatera Utara and Laboratory of Agrichemists and Natural Resources at the Industrial Research and Standardization Office of Medan. This research was designed using Completely Randomized Design (CRD) factorial pattern of 3 x 3 with 3 replications, as factor I was the dose of Indigenous Microorganisms (IMO) and factor II was the duration of fermentation. The parameters measured were water content/dry matter, crude fat, crude protein, crude fibre, ash, and Non Nitrogen Free Extract (NNFE) using proximate analysis. The results showed that fermentation of cassava peel using Indigenous Microorganisms (IMO) with the variation of Indigenous Microorganisms (IMO) dose and duration of fermentation give effects, that were increased water content, crude protein, and Non Nitrogen Free Extract (NNFE) and decreased dry ingredient, crude fat, crude fibre, and ash content.
