Abstract

Background. This research was conducted to determine the feasibility of the formol titration method in measuring protein content in fresh milk. Material and method. The material used in this study was a sample of fresh cow's milk. Standard milk was prepared by adding hydrolyzed casein to obtain protein content of 10%, 8%, 6%, 4% and 2%. Each standard was triplicate tested to obtain LOD, LOQ, accuracy and precision calculations. The data obtained is then presented descriptively. Results. The results obtained show that the formol titration method achieves an LOD value of 2.12%, LOQ of 6.41%, an accuracy rate of 145.56% and a precision of 2;4;6;8;10% are 3.58;4.40;3.12;3.58;2.58%. The resulting linear curve has a regression equation Y=2.0228X – 2.785 with an R2 value of 0.957. Conclusion. It can be concluded that the measurement of milk protein using the formol titration method is quite good, but less accurate because it tends to be overquantify.

Abstract

metabolized by the human body. There are various dairy livestock spread around Indonesia specifically dairy cattle, dairy goats, buffalo, and sheep. This research aimed to forecast the milk production of various dairy livestock in Indonesia until 2028. The research method of this study was the secondary data method utilizing secondary data from the Food and Agriculture Organization (FAO) of the United Nation. Data used in this study was milk production of Indonesia from various dairy livestock in tonnes from 2012-2021. The Autoregressive integrated moving average (ARIMA) method was used to forecast milk production in Indonesia. The (p,d,q) value for the milk production forecast of dairy cattle, dairy goat, buffalo, and sheep were (1,1,1), (2,1,1), (0,0,1), and (1,1,1) respectively. Milk production for cows, goats and sheep is predicted to continue to increase until 2028, while buffalo milk production is predicted to decrease. Milk production from various dairy livestock besides dairy cattle has great potential to develop so as to create diversity in fulfilling the needs of dairy products in Indonesia.

Abstract

Background. The study entitled Total Concentrations of VFA and N-NH3 in Ruminant Feed Using Different Tree Legumes with Various Protein Sources In Vitro, aims to determine the optimal mulberry leaf tannins to be given to livestock in vitro and to determine the effect on total VFA and N-NH3 in vitro. Materials and methods. The material used in the in vitro experiment was rumen fluid from three beef cattle at the Bantarwuni Slaughterhouse, Kembaran District, Banyumas Regency. The feed ingredients used were 40% field grass, 30% cassava, 20% pollar, and 10% from several protein sources (soybean meal (R1), calliandra leaves (R2), lamtoro leaves (R3), and indigofera leaves (R4). The study was conducted in vitro using an experimental method with 5 different treatments, each treatment was repeated 4 times so that there were 20 treatment units.The measured variables were total VFA production and ammonia nitrogen (N-NH3). Results. The results showed that the use of Indigofera leaves in the ration produced the highest total VFA and N-NH3, namely 111.00 ± 20.68 mM and 9.90 ± 0.66 mm. Conclusion. It was concluded that the use of protein source feed in the form of tree legumes can be used as a substitute for soybean meal as feed for ruminants, Indigofera Zollingeriana is a tree legiminosa which is the best substitute for soybean meal.

Abstract

Taufk Nur Hidayat. The research is entitled "The Effect of Ozonization Time on Total Solids and Viscosity of Etawa Crossbreed Goat Milk (PE)". This research aims to determine the effect of time ozonization of Etawa crossbreed goat milk on total solids and viscosity. This research was carried out experimentally using a Completely Randomized Design (CRD) which contained 5 treatments and 4 replications so that there were 20 experimental units. The materials used in this research were using Etawa crossbreed goat milk and equipment in the form of an ozone generator, with an ozone concentration used of 1000 mg/hour, an ice box as a place to store milk samples, a 1000 ml glass jar, 50 ml bakerglass, 300 ml jar bottle. ml, glass stirrer, label, tissue, lactoscan, and viscometer. The treatments used were ozonation periods of 0, 20, 40 and 60 seconds. The important variables observed in this research are total solids and viscosity. The results of the data obtained from the research that has been carried out are then analyzed using ANOVA. The results of the research on total solids and milk viscosity did not have a significant effect. The conclusion obtained from the research is that the length of ozonation has no effect on the total solids and viscosity of Etawa Peranakan goat milk (PE).​
