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.

Abstract

This study aims to look at the effect of buffalo and goat manure on the growth of Indigofera zollingeriana plants. This research was carried out in Parlondut Village, Pangururan Subdistrict, Samosir Regency, North Sumatra from March to May 2018. The design used in this study was a Completely Randomized Design with 4 replications. P0 = Buffalo Cage Fertilizer 25% + 75% Top Soil Soil, P1 = Buffalo Cage Fertilizer 50% + 50% Top Soil Soil, P2 = Buffalo Cage Fertilizer 75% + 25% Top Soil Soil, P3 = 25% Goat Cage Fertilizer + 75% Top Soil Soil, P4 = Goat Cage Fertilizer 50% + 50% Top Soil Soil and P5 = Goat Cage Fertilizer 75% + 25% Top Soil Soil. The variables observed were plant height, number of leaves, number of stems, stem diameter and leaf width. The results showed that the application of manure from goats had a significant effect on the parameters of the study, namely plant height, number of leaves, number of branches and stem diameter. In conclusion, the increasing dosage of fertilization with goat manure on Indigofera zollingeriana plants, the results are getting better.

Abstract

The purpose of this study were to identify factors that affect the demand for chicken eggs and to find out the correlation of factors that affect consumer behavior in purchasing chicken eggs in Tebing Tinggi City. The research used primary data obtained from questionnaires or interviews. The research method was multiple linear regression methods, spearman rank correlation and contingency correlation. The results showed that the price of chicken eggs and the income had real effect to the demand for chicken eggs in the area of research. The result of spearman rank correlation and the contingency correlation showed that there was a real correlation between the income with a consumer behavior in purchasing chicken eggs, while the age, employment, and number of consumer dependents, did not show real correlation with consumer behavior in purchasing chicken eggs.
