Abstract

The goal of this study was determine the influence of honey harvesting age in the area of the calliandra plant to diastase enzyme activity, hidroxymetilfurfural (HMF) and acidity. The method of this study was experiments (RAL) with 3 treatments and five replication. The observations of this study were P1 (honey harvested in 11 days), P2 (honey harvested in 14 days), and P3 (honey harvested in 17 days). The variable in this study is the activity of diastase enzyme, hidroxymetilfurfural (HMF) and acidity. Data of this study were analyzed with the Range Analysis (ANOVA), if there is a significant difference between treatments, analysis of data was continued with the Smallest Real Difference Test (BNT). The results of this study showed that the honey harvesting age gave significant effect (p<0.01) on diastase enzymes activities, hidroxymetilfurfural and acidity. As a conclusion, honey harvesting age influences the quality of the activity of the diastase enzyme, hidroxymetilfurfural and acidity. The best content of diastase enzyme, was found in P3 treatment that is generated in 17th day of harvesting with the value 11.12 DN due to it was longer in the nest before harvested. The best content of hidroximetilfurfural was found in P3 with the value 4.48 mg/kg and the best content of acidity honey was found in P3 with the value 28.42 NaOH/kg.

Abstract

The study objective was to determine the effect of utilization various lipids with different concentration on physical quality of whey-porang composite edible films. The materials of the study were albumen, whey powder, porang flour and lipids (butter, margarine, beeswax and palm oil). The type of lipids were P1 (beeswax), P2 (margarine), P3 (butter) and P4 (palm oil), and its concentration were 5% and 10%.  The variables were moisture content, film thickness, tensile strength and percentage of prolongation. The treatment was designed by nested completely randomized design (CRD) and the data were analyzed by analysis of variance. The Duncans Multiple Range Test (DMRT) was applied if there were significant differences among treatments. The study found that type of lipids with different concentration had a very highly significant differences (P<0.01) on the moisture content and the tensile strength of edible film. Meanwhile, utilization of various lipids had a significant differences (P<0.05) on the film thickness of edible film, but not on its different concentration. Besides, type of lipid did not significantly influence (P<0.05) the percentage of edible film prolongation. However, its various concentration had a very highly significant differences (P<0.01) on the percentage of edible film prolongation. It can be concluded that utilization of several lipids with various concentrations in whey-porang composite edible films could reduce moisture content, tensile strength, and percentage of composite edible films prolongation but increased the film thickness. The study suggested to use butter lipids with 5% concentration to produce good mechanical edible films. The study needs further experiment about chemical quality and sensory test.Keywords: lipid, physical quality, whey, porang, composite edible films

The research materials were 94 Friesian crossbred dairy cow’s milk in 3 milk collecting centers which were located in three locations i.e. Sidomulyo (n=29), Slamparejo (n=30) and Kemiri (n=35). The research method was survey to 94 dairy farmers. Milk qualities consisted of density and fat which were measured by milk analyzer lactoscanner, also milk grade which was determined by reduction time. The results showed that 74% of sample had milk density 1.024 g/ml; 100% of sample had more than 3% of fat and 84% of sample was categorized as 1st grade because their reduction time was more than 5 hours. Milk density increased by adding concentrate (R2=0.022), while milk fat decreased by adding concentrate (R2=0.110). The higher the subclinical mastitis rate the higher the milk fat (R2=0.110). Milk sample which was in 1st grade came from farmers who cleaned their stall floor 3 times per day.   Keywords: Sanitation, milk quality, dairy cow
