Penelitian ini dilakukan untuk mengetahui perbedaan metode pengujian protein (Bradford dan Titrasi  formol) pada susu segar terhadap kadar protein, lama analisis, dan biaya. Penelitian telah dilaksanakan di laboratorium gedung Integrated Academic Building (IAB), Universitas Jenderal Soedirman, Purwokerto. Materi yang digunakan pada penelitian ini adalah sampel berupa susu sapi segar yang diperoleh dari 30 ekor sapi perah. Variabel yang diukur yaitu kadar protein, lama analisis dan biaya yang dibutuhkan tiap analisis protein. Data dianalisis menggunkan analisis deskriptif, uji T dan analisis korelasi pearson. Nilai kadar protein yang diperoleh dengan metode Bradford  antara 1,81 - 2,74% dan Titrasi  formol antara 2,2 - 3,7%. Rataan kadar protein Bradford 2,23±0,26% dan titrasi  formol 2,96±0,43%. Waktu yang dibutuhkan diperoleh pada metode Bradford 17 menit dan titrasi  formol  5,15 – 5,6 menit. Rataan waktu Bradford 17±0 menit dan titrasi  formol 5,37±0,12 menit sedangkan untuk biaya yang dibutuhkan pada metode Bradford 2.000,00 Rupiah dan titrasi  formol 1.164,55 – 1.170,88 Rupiah. Rataan biaya yang butuhkan pada Bradford 2.000,00±0 Rupiah dan Titrasi  formol 1.167,76±1,82 Rupiah. Hasil Uji T menunjukkan bahwa pengujian kadar protein menggunakan metode Bradford dan titrasi  formol berbeda nyata (P<0,05) terhadap kadar protein, lama analisis dan biaya. Analisis korelasi Pearson 0,19 menunjukkan adanya hubungan yang sangat lemah antara metode pengukuran kadar protein Bradford dengan titrasi  formol. Pengukuran kadar protein titrasi  formol memberikan hasil yang lebih sensitif terhadap kadar protein susu segar dengan cepat dan biaya analisis lebih murah.

This study was conducted to determine the differences in protein testing methods (Bradford and Formol Titration) in fresh milk on protein content, length of analysis, and cost. The research has been carried out in the laboratory of the Integrated Academic Building (IAB), Jenderal Sudirman University, Purwokerto. The material used in this study was a sample of fresh cow's milk obtained from 30 dairy cows. The variables measured were protein content, length of analysis and The Coast required for each protein analysis. Data were analyzed pusing descriptive analysis, T test and Pearson correlation analysis. The value of protein content obtained by the Bradford method 1.81 – 2.74% and formol titration 2.2 – 3.7%. Average protein content of Bradford 2.23±0.26% and formol titration 2.96±0.43%. The time required si obtained by the Bradford method 17 minutes and formol titration 5.15 – 5.6 minutes. The average Time of Bradford 17±0 minutes and formol titration 5.37±0.12 minutes, while for the Coast required for the Bradford method 2,000.00 Rupiah and formol titration 1,164.55 – 1,170.88 Rupiah. Average Coast required for Bradford 2,000.00±0 Rupiah and formol titration 1,167.76±1.82 Rupiah. The results of the T test showed that the testing of protein Content using the Bradford method and formol titration was significantly different (P<0.05) on protein content, length of analysis and cost. Pearson correlation analysis = 0.19 showed a very leak relationship between the Bradford protein content measurement method and formol titration. Measurement  of protein content formol titration provides results That are More sensitif to the protein content of fresh Milk quickly and the cost of analysis is cheaper.
