Abstract

The aim of the study was to determine the effect of the tapioca flour level substitution on physical characteristics and organoleptic values of sausage made of male horse’s meat.The material used was meat of 4.0-4.5 years old male horse and a number of spices in making sausages. This study was conducted in a One Way Completely Randomized Design with four treatments and three replications, namely P1 = Control (without tapioca flour); P2 = 15% tapioca flour; P3 = 30% tapioca flour and P4 = 45% tapioca flour. The data obtained were analyzed using analysis of variance. The treatments which significantly different were then continued analyzed using the Duncan New Multiple Range Test. The results showed that the level of tapioca flour substitution had a significant effect (P <0.05) on water holding capacity (WHC), color, aroma and texture of the sausage, while the cooking lost, tensile strength, pH, and taste were not affected significantly (P> 0.05). The substitution of 30% tapioca flour from the ingedients gave the highest value of horse’s meat sausages in WHC of (45.74 ± 8.18) %, but low in cooking losses of (3.33 ± 1.15) %, low tensile strength of (0.45 ± 0.00) kg/cm2 and normal pH (6.66 ± 0.05). Based on organoleptic values that substitution of 30% tapioca flour gave slightly brown color of sausage (3.83 ± 0.03), good aroma (5.95 ± 0.04), delicious taste (6.20 ± 0.03) and soft texture (5.68 ± 0.02).

Abstract

Processed meat products that are common and much preferred by the consumers are sausages and beef meatballs. This processed product has the disadvantage that it has a high-fat content, causing faster oxidative damage. This study aims to observe differences in the nutritional value and antioxidant activity of meatballs and sausages from Bali-beef and Lamtoro-beef. The main research material is fresh Bali-beef and lamtoro beef using several chemicals and laboratory equipment related to proximate analysis and antioxidant testing. The study was designed based on a Completely Randomized Design with 4 treatments and 3 replications and continued with Duncan's test SPSS version 16 programme. The results showed that the highest crude protein content was found in lamtoro-beef with lower fat content, water content, and ash content compared to fresh Bali-beef. Meatball and sausage products with the raw material of lamtoro-beef were not significantly (P>0.05) had a higher crude protein content than meatballs and sausages with the raw material of Balin-beef. The antioxidant activity of fresh Bali-beef and its processed products (meatballs and sausages) was not significantly (P>0.05) higher than the antioxidant activity of lamtoro-beef. Conclusion: Lamtoro-beef and its processed products in the form of meatballs and sausages have a higher protein content with lower fat content, water content and ash content compared to fresh Bali-beef. Meatball and sausage products made from fresh beef were not significantly (P>0.05) had higher antioxidant activity than lamtoro-beef.

Abstract

Edible film is an alternative packaging that can be applied to food because it has biodegradable properties. The use of plasticizers can be used in the manufacture of edible films to increase the flexibility and densibility of the film. This study aims to determine the effect of plasticizer type on the thickness, WVTR, and moisture content of whey-gelatin film blends. The research was conducted in a Completely Randomized Design with three treatments, treatments that make a difference are tested with Duncan's Multiple Range Test (DMRT). The treatment used different plasticizer (P1G: Glycerol; P1S: Sorbitol; and P1P: polyethylene glycol (PEG) 400). The properties of whey-gelatin films showed that thickness was at 0.0350-0.0352 mm; the WVTR was at 4.87-6.22 g/m2/day; the water content was at 12.55-15.69%. The use of glycerol as plasticizer produced the best edible film characteristics compared to sorbitol and PEG 400 with a thickness value of 0.0350 mm; WVTR of 6.22 g/mm2/day and moisture content of 12.55%.

Abstract

Edible film is a biodegradable packaging that can be an alternative as a food packaging material so as to reduce environmental damage and still have the function of maintaining the shelf life, quality and safety of food products. The aim of this research was to determine the effect of using different percentage of whey-chia seed and plasticizer type on the characteristics of films. This research used a completely randomized factorial design consisting of Factor A: percentage of whey-chia seed (A1= 1:0.5; A2= 1:0.75 and A3= 1:1) and Factor B: type of plasticizer (B1= sorbitol; B2= glycerol and B3= PEG). The interaction between of whey-chia seed and different types of plasticizer did not show a significant effect (p>0.05) on the characteristics of films, but the factor of whey-chia seed gave an effect on the thickness and gelation time of the films and the factor of different types of plasticizer too gave a significant effect (p<0.01) on the water vapor transmission rate (WVTR) value. The findings suggest that the incorporation of chia seed concentration with distinct plasticizers could enhance the physical properties of whey-based edible film. The use of percentage of whey-chia seed 1:1 with glycerol is the best treatment.

Abstract

This research aims to determine the performance of male Peking ducks given rations containing fermented pineapple peel at the Teaching Farm, Faculty of Animal Science, University of Mataram. The research was carried out for 10 weeks using a Completely Randomized Design, consisting of 6 treatments and 5 replications. Each replication used 8 male Peking ducks aged two weeks so that the number of ducks used was 240. The treatments were P0 = control, P1 = 5% fermented pineapple peel, P2 = 10% fermented pineapple peel, P3 = 15% fermented pineapple peel, P4 = 20% fermented pineapple peel and P5 = 25% fermented pineapple peel. The research variables were: final body weight, body weight gain, ration consumption, Feed Converation Ratio, percentage of carcass and non-carcass analyzed using analysis of variance. The results of the study showed that giving fermented pineapple peel up to a level of 25% had a significant effect (P<0.05) on final body weight, body weight gain and feed consumption, but was not significantly different (P>0.05) on the feed conversion ratio, carcass percentage, small intestine length, small intestine percentage, liver percentage, and leg percentage. Conclusion: Providing fermented pineapple peel to a level of 10% increased final weight, body weight gain, feed consumption, head and neck percentage but reduced heart percentage and gizzard percentage. Feed conversion ratio, carcass percentage, small intestine length, small intestine percentage, liver percentage, and leg percentage were relatively similar between treatments.

Abstract

Cellulolytic bacteria are bacteria that produce cellulase enzymes capable of degrading cellulose substrates. This study aimed to isolate and identify as well as measure the cellulase enzyme activity of cellulolytic bacteria isolated from the digestive tract of swans (Cygnus olor) in Mataram. The bacteria were isolated using de Man Rogosa Sharpe (MRS) selective media with the spread plate method. Then, the extracellular enzyme activity test was conducted by growing selected pure isolates on 1% Carboxy Methyl Cellulose (CMC 1%) media, followed by pouring 0.1% congo red solution and rinsing with 1M NaCl solution to determine cellulolytic activity (cellulolytic potential indicated by the appearance of a clear zone around the colony) and measuring the cellulolytic index. The bacterial isolation results obtained 4 isolates with the potential to support fiber degradation in animal feed. The highest cellulolytic index was produced by the isolate coded S1, reaching 34.5 mm, while the lowest cellulolytic index was produced by 2 isolates coded J21 and I2, reaching 18.8 mm.
