Abstract

Chicken meat is one of the basic ingredients of food that is preferred by the community because of its high nutrition and affordable prices. However, this high nutrition causes chicken meat to be easily contaminated with microorganisms, so it is necessary to process it with good sanitation so as to reduce the possibility of meat being contaminated by microorganisms and can be consumed healthily. This study aims to determine the process of implementing sanitation in the catering DM and to find out the total number of bacteria and Staphylococcus aureus in fried chicken and processed grilled chicken in DM catering. The results showed that the total number of bacteria in fried chicken was 1,57 x 106 < µ < 2,66 x 106 cfu/g, while in grilled chicken 1,74 x 106 < µ < 2,59 x 106 cfu/g, the results of the analysis of the calculation of the total number of S. aureus bacteria in fried chicken is 4,9 x 101 < µ < 7,1 x 101 cfu/g while for grilled chicken it is 5,1 x 101 < µ < 7,6 x 101 cfu/g. From these results it can be concluded that the total number of bacteria in DM catering exceeds the maximum limit. has been determined by BPOM but the total number of S. aureus bacteria in DM catering is still below the limit set by BPOM.

Abstract

Cherry leaves are an alternative material that can be used as a natural disinfectant because they contain active compounds in the form of flavonoids, saponins, and tannins which can work as antibacterial compounds in milk storage rooms. The purpose of this study was to determine the effect of using cherry leaves extract as a natural disinfectant through testing the inhibition zone and calculating the total number of bacteria in the milk storage room, and for knowing the concentration of cherry leaves which showed the best inhibition in the milk storage room. The study was conducted experimentally using Completely Randomized Design (CRD) and continued with Tukey's Test and Orthogonal Polynomial Test with three treatments, namely P1 (30% concentration), P2 (40% concentration), and P3 (50% concentration) with five replications. The results showed that cherry leaves extract was able to inhibit gram-positive bacteria in the form of cocci and bacilli and gram-negative bacteria in the form of cocci.. Extract of cherry leaves with a concentration of 50% was the most effective concentration as a natural disinfectant with an average inhibition zone formed of 9.73 mm against gram-positive bacteria cocci form, 9.22 mm against gram-positive bacteria in the form of bacilli, and 9.40 mm against bacteria gram negative cocci form, and the average decrease in the total number of bacteria was 92.51% on the floor.

Abstract

Cherry leaves are an alternative material that can be used as a natural disinfectant because they contain active com-pounds in the form of flavonoids, saponins, and tannins which can work as antibacterial compounds in duck egg hatching machines. The purpose of this study was to determine the effect of cherry leaf infusion and the most effective concentration level on the ability to reduce the number of bacteria and inhibit bac-teria in duck egg hatching machines. This research was conduc-ted experimentally using a Completely Randomized Design (CRD) and continued with the Tukey test with three treatments, namely P1 (50% concentration), P2 (75% concentration), and P3 (100% concentration) and six replications. The observed varia-bles were the decrease in the number of bacteria, inhibition zone of bacilli bacteria and inhibition zone of bacteria coccus in the duck egg hatching machine. The results showed that cherry leaf infusion had the same effect (P>0.05) on decreasing the number of bacteria and showed a different effect (P<0.05) on the inhibi-tion zone of gram positive and gram negative bacilli but had no effect on the inhibition zone gram negative and positive cocci bacteria, and cherry leaf infusion with a concentration of 75% produced the most effective inhibition zone for decreasing the number of bacteria and the ability to inhibit bacteria.

Abstract

Rejected laying hens meat are less attractive to the public, because it has a tough texture. Guava fruit (Psidium guajava) contains ascorbic acid which can be used as a meat tenderizer, therefore research was carried out to determine the effect of giving guava extract (Psidium guajava) to water holding capacity, cooking loss, tenderness and pH of rejected layer hens meat. The research has been carried out at the Laboratory of Animal Products Processing Technology, Faculty of Animal Husbandry, Padjadjaran University on March 2021. The research was conducted with experimen-tally methods using a completely randomized design (CRD) with 4 treatments is the immersion of guava extract with an amount of 20% (P1), 30% (P2), 40% (P3), 50% (P4). Immersion was carried out for 30 minutes with each treatment repeatition 5 times. The result of this research were giving guava extract with a concentration of 40% gave the best effect with using Duncan’s multiple rage test, with the value of water holding capacity 20,11 %, cooking loss 28,28 %, tenderness 30,28 mm/g/10 second and pH 6,64 on rejected layer hens meat.

Abstract

Chicken is one of the animal protein sources utilized to fulfill humans nutritional needs. Chicken is prone to be damaged and susceptible to be contaminated by pathogenic bacterial because chicken contains high nutrition. Ground meat is one of the livestock food production processed by meat-cutting and frequently sold in supermarkets. This research aims to seek the quality of microbial in chicken sold in supermarkets located in Jatinangor region. Specifically, this study attempts to ascertain the amount of bacterial and Staphylococcus aureus contained in chicken. The sampling method is carried out by simple random sampling in which the chickens are obtained from two different supermarkets in Jatinangor region. Furthermore, the calculation is carried out by using Total Plate Count (TPC) and the result is analyzed statistically by the descriptive method. The result shows that the average number of bacteria in Supermarket A is 5,43 x 10⁷ CFU/g, while in Supermarket B is 4,64 x 10⁷ CFU/g. Correspondingly, the amount of Staphylococcus aureus in Supermarket A is 7,2 x 10⁴ CFU/g and in Supermarket B is  2,9 x 10⁴ CFU/g. The number of bacterial and Staphylococcus aureus in ground chicken in both supermarkets exceeds the maximum number of microbial contamination limitations that have been determined by SNI in 2009 No.7388 which are 1 x 10⁶ CFU/g and 1 x 10 ² CFU/g.
