THE EFFECT OF GUAVA LEAF SOLUTION CONCENTRATION AND SOAKING DURATION ON THE QUALITY OF CHICKEN EGGS.      This study aims to determine the effect of guava leaf solution concentration and soaking time on the quality of chicken eggs. This research was conducted from November to December 2018, at the Laboratory of Animal Product Technology, Faculty of Animal Husbandry, Sam Ratulangi University, Manado. The method used is Completely Randomized Design (CRD) with a factorial pattern consisting of 2 factors. Factor A was the concentration of solution of guava leaves and factor B is the length of immersion with 4 replications. The treatments used are: Factor A concentration of solution of guava leaves A1 = 3%, A2 = 6%, A3 = 9%, A4 = 12%. Factor B was duration of immersion B1 = 6 hours, B2 = 12 hours, B3 = 18 hours, B4 = 24 hours. The variables analyzed were a decrease in egg weight, egg white index and egg yolk index. Data obtained were analyzed by variety. If there are significant differences between treatments, it will be continued with Duncan Test. The results of the variance analysis showed that the interaction had a significant effect (P <0.05) on the decrease in egg weight and did not significantly influence (P> 0.05) on the egg white index and egg yolk index. Duncan's Test results for decreasing egg weight showed the concentration of guava leaf solution 3% and soaking time 6 hours  gave good results for the quality of chicken eggs. It was concluded that the concentration of 3% and the soaking time of 6 hours gives good results on decreasing egg weight. As for the egg white index and egg yolk index showed good results with concentration of 12% and 24-hour immersion time. Keywords: Guava leaf, Egg weight, Egg white index, Egg yolk index.

This research was aimed to compare the small and big truncation point proportions intended to evaluate gain values of genetic improvement for Indonesian Local cow breed groups selected for Agrotechnopark (integrated bio-cycle farming system) intensification. Animal live weights were collected from 674 Indonesian grade breed cows kept by local household farmers in North Sulawesi province. Data of cows were corrected by adjusting to six years old ages. All cows were divided into three breed groups with different genetic compositions of Bali breed cow generation (BG) of 207 cows, Ongole grade cow generation (OG) of 189 cows, and Local grade cow generation (LG) of 178 cows. The genetic improvements of BG, OG and LG were analyzed involving selection intensity (i), accuracy of selection (r), and standard deviation (SD) of breed group traits under selection. Results of this study showed that the critical components was genetic development of local grade breeds by choosing small proportion of 10% truncation point for Agrotechnopark intensification of selected elite cows groups among BG, OG and LG populations with the positive live weight gains of 58.6 kg, 23.15 kg, and 28.62 kg per generation, respectively compared with larger percentages of 20% and 30% proportions of truncation points.

THE EFFECT OF DIFFERENCES CONCENTRATION OF NATIVE CHICKEN CLAW GELATIN ON THE PHISYCAL CHARACTERISTICS OF EDIBLE FILM. This study aims to determine the effect of differences concentration on the physical characteristics of edible film from native chicken claw gelatin. This study used a completely randomized design with the treatment of chicken claw gelatin concentration 5%, 10%, 15 and 20%, each treatment repeated four times. The results showed that the differences concentration of native chicken claw gelatin had significantly different effect (P<0.05) on the value of tensile strength, elongation and thickness of edible film. Based on the results of discussion, it can be concluded that the concentration of native chicken claw gelatin from variables with 10% gelatin concentration had good physical characteristics of edible film. Keywords: Native chicken claw, Edible film Gelatin

SENSORY QUALITY OF ICE CREAM ADDED BY RED DRAGON FRUIT (Hylocereus polyrhizus). The study was conducted to determine the addition of red dragon fruit on the sensory quality of ice cream. This study used UHT  milk, milk of skim milk, whipped cream, gelatin powder, aquades, granulated sugar, egg yolks and 16 dragon fruit. The design used was a Completely Randomized Design (CRD) consisting of 5 treatments and 40 replications. The variables analyzed in this study were sensory quality (color, aroma, texture, taste). Data obtained were analyzed using ANOVA. The significant differences between treatments were tested by the BNJ test. The results indicated that the red dragon fruit in the treatments of R0, R1, R2, R3, and R4 gave a very significant influence (P <0.01) on color, aroma, texture, and taste of ice cream and the results of BNJ's further test showed R4 treatment (40% red dragon fruit) had the best results on the sensory properties of ice cream. Therefore, it was concluded that the addition of 40% red dragon fruit provided good sensory quality of ice cream. Keywords: Ice cream, Red Dragon Fruit, Sensory Properties

THE EFFECT OF THE ADDITION OF HONEY TO THE PH VALUE, SYNERESIS AND TOTAL LACTIC ACID BACTERIA OF SINBIOTIK YOGURT. This study was conducted to determine whether honey gives an influence on the pH value, syneresis and LAB of synbiotic yogurt. In this study, the main ingredients used were 5 liters UHT milk, Skim milk 400 g, honey 240 mL, Lactobacillus acidophillus bacteria, Streptococcus thermophilus and Lactobacillus bulgaricus, aqudes, MRS Media (Man Rogosa Sharpe Medium). Equipment used during the study included autoclave, pH meter, Erlenmeyer, test tube, pipette, thermometer, analytical scale, petri dishe, desiccator, blender, oven, incubator, micro pipette, burette, spritus lamp, goblet, refrigerator. This research was carried out on January 7 2019 until March 12 2019 at the Laboratory of Animal Product Technology Faculty of Animal Husbandry, Sam Ratulangi University, Manado. The experimental design used in this study was a Completely Randomized Design (CRD) method with treatments 5 and 4 replications. The variables analyzed in this study are pH, Sinereis and Total LAB. The data obtained were analyzed using ANOVA, there were significant differences between the treatments followed by the BNJ test. The results of this study indicate that the treatments of P0(0%), P1(3%), P2(6%), P3(9%) and P4(12%) have a very significant effect (P <0.01) on the pH value, Sineresis and Total LAB. Based on the results and discussion that the use of honey by 12% can increase the value and produce the best pH, syneresis and total lactic acid bacteria in synbiotic yogurt.Keywords: Sinbiotic Yogurt, Honey, pH, Sinresis, LAB.
