Background. The study was entitled "Percentage of Damage and Total Fresh Milk Bacteria in the Andini Lestari Dairy Farmer Group and Tirta Sari Aji Banyumas Regency". The purpose of this research was to determine percentage of damage and total bacteria in fress milk in the Andini Lestari dairy cattle group of Cilongok District and the Tirta Sari Aji dairy cattle in Karanglewas District. The research was conducted on 2 August 2019 until 28 September 2019. Materials and Methods. The material used is dairy farmers and milk. Dairy milk samples were obtained from 15 cattle from the Andini Lestari breeder group in Cilongok District and 15 cattle from Tirta Sari Aji, Karanglewas District, Banyumas Regency. The research method uses the survey method by conducting interviews and direct field observations. The response variables measured and observed in this study were milk damage and total milk bacteria. Milk samples obtained from the farms are then taken to the Dairy Production Laboratory for total microbial testing using the Total Plate Count Test and milk damage using the Alcohol Test. Results. The results showed that the alcohol test in the Andini Lestari group contained none positive samples or the presence of lumps in milk, while in the Tirta sari Aji group there were two positive samples of milk. Analysis of the sign test showed the level of milk damage in the two districts was not significantly different (P > 0.05). The results of total microbial studies in the two groups had an average of 16.22 x 104 cfu / ml and 14.44 x 104 cfu / ml. Analysis of the "t" test showed that the total microbes in the two groups were significantly different (P < 0.05). Conclusion. The quality of fresh milk in percentage of damage and total microbial in both Cilongok and Karanglewas Districts is considered good (according to SNI 2011).

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.

ANALISIS EFISIENSI BIAYA DAN KEUNTUNGAN USAHA SUSU KAMBING PERANAKAN ETAWA DI KECAMATAN KALIGESING KABUPATEN PURWOREJO (STUDI KASUS 4 PERUSAHAAN DI KECAMATAN KALIGESING) Wihandoyo, Dika; Wakhidati, Yusmi Nur; Subagyo, Yusuf

Background. This study aims to calculate revenue, total costs, profits and efficiency analysis seen from the R/C Ratio of the Etawa crossbreed goat milk business on a small scale and large scale business in Kaligesing sub-district, and to see whether there is an effect of the relationship between efficiency analysis and large scale business. small business scale by using the Independent Sample t test. Materials and methods. The sampling method of respondents used a purposive sampling method (deliberately), namely the area that has a commercial Etawa crossbreed goat milk business. Collecting data using the Survey Method, namely conducting interviews with the help of questionnaires and direct field observations. Results. The results of the previous survey found that there were dairy companies, namely Cipta Mandir, Wiranto Farm, Kaisa Farm and Goat-Milk. The results of the research on the acceptance of the 2 business scales on average, namely the small business scale of IDR 63,525,000 / period and the large business scale of IDR 193,950,000 / period. The total cost on a small scale business is IDR 47,335,000 / period and a large business scale of IDR 140,260,000 / period. The profit on a small scale business is IDR 16,190,000 / period and a large business scale of IDR 53,690,000 / period. The results of the analysis of the R/C ratio of the Etawa crossbreed goat milk business on a small and large scale on average are 1.34 and 1.38. The results of the t-test or difference analysis show that there is no difference in profits and R/C ratio between small and large scale businesses.
