Abstract

This study aims to evaluate the potential of gelatin extract from bali cowhide in maintaining the quality of duck eggs and determine the response of panelists to the quality of post-soaking gelatin extract eggs. This research has been carried out at the Animal Husbandry and Microbiology Technology Laboratory, Faculty of Animal Husbandry, Udayana University. This study lasted for one month from May 4 to June 4, 2018. The design used was a Completely Randomized Design (CRD) with five treatments and three repetitions. The treatments were without soaking or control (P0) soaking gelatin for 15 minutes (P15) soaking gelatin for 30 minutes (P30) soaking gelatin for 45 minutes (P45) and soaking gelatin for 60 minutes (P60). The variables observed were egg white index, egg yolk index, egg yolk color, egg aroma and egg flavor. The results showed that there was an influence between the length of the duck egg immersion and the control or not given the gelatin soaking of bali cowhide on the panelist's preference for the color of yolk, flavor and aroma was significantly different (P <0.05) this was due to the alleged gelatin immersion to maintain and the penetration of gelatin protein with protein in eggs and can maintain the decomposition of fat and carbohydrates in duck eggs while the yolk index and egg white index have no significant effect (P> 0.05) this is due to the high molecule in gelatin which is in the range 67-167 kilodalton so that the penetration of gelatin in covering the pores of egg shells is not optimal and the occurrence of gelatin clotting occurs during storage which has an unreal effect. Based on the results of the study that the administration of gelatin solution from bali cowhide extract can provide better quality duck eggs and can increase panelist preference in egg yolks, egg flavor and egg aroma. In general, the 15 minute soaking time gives the quality of egg yolks, egg flavor and good egg aroma to duck eggs. Keywords: gelatin, soaking, duck eggs

Abstract

This experiment aims to determine the population of phosphate solubilizing bacteria (PSB) in non-rhizosphere and rhizosphere plants on dry land in the rainy season. The experiment was conducted for 3 months including sampling at three strata system farm of Faculty of Animal Husbandry at Bukit Jimbaran; analysis of soil at Laboratory of Animal Production Technology and Microbiology Faculty of Animal Husbandry and at Soil Science Laboratory, Faculty of Agriculture, Udayana University. This experiment follows an additive linear model with the assumption that the difference only caused by the different types of plants while other factors are uniformly homogeneous. Sampling was done on four rhizosfere including; non-rhizosphere (NR), Gliricidia sepium rhizosphere (RG), Leucaena leucochepala rhizosphere (RL), and Sesbania grandiflora rhizosphere (RT) with four replications. The variables observed in this experiment including: Total PlateCount (TPC), Total phosphate solubilizing bacteria (PSB), P (phosphorus) element, and water content. The result showed that TPC soil in the range of 0,57×108-5,6×108cfu/g, showed no significant different to all treatment. Total phosphate solubilizing bacteria (PSB) in range of 0,35×107 - 2,88×107cfu/g showed no significant different to all treatments. P (phosphorus) elements, in tretment NR same withtreatment RT are range of 10,27ppm significant different with RG and RL. Water content ranged from 9,25 - 9,84 % With the result is highest in treatment RG was no significant higher than RT and markedly higher than the NR and RL. Based on the experiment it could be concluded that the population of phosphate solubilizing bacteria (PSB) in non-rhizosphere tend to is lower compared with RG, RL, and RT on dry land in the rainy season. The content of P (phosphorus) element in non-rhizosphere is same with RT but lower than RG and RL. Water content in non-rhizosphere same with RL but lower than RG and RT. Keywords: phosphate solubilizing bacteria, non rhizosphere, rhizosphere
