The testing laboratory shall monitor the perfomance of the test by comparing the test results of other laboratories, as an external quality assurance. Preliminary tests such as homogeneity test and stability test. This study aims to ensure the validity of the test results as outlined through a proficiency test (homogeneity test) with a sampel test conducted in duplicate. Homogeneity test according to ISO 13528 is to prepare and pack proficiency test samples and take at random at least 10 packages per pack of sample making. Homogeneity test of urea Prill Fertilizer samples from PT.Pupuk Sriwidjaja using biuret analysis parameters, and UV-Vis spectrophotometer instrument. The result of the analysis of  urea prill using the biuret analysis parameters meet the quality requirements of SNI 2801-2010, which is below 1,2% in the range of results obtained are 0,33 , 0,34 , 0,35 , 0,36. Sample of urea prill as a proficiency test material was declared homogeneous with value of Ss ≤ 0,3 SDPA, the results obtained from this study were Ss 0,004773 ≤ 0,004871 SDPA homogeneous sample.
