The research method used is a quantitative approach with proportionate stratified random sampling data type. Information was collected through questionnaires distributed to employees. The study population was 329 employees of PGRI Palembang University. However, for research purposes, the researcher determined that only employees from 6 faculties were the focus, namely 160 individuals, the sampling technique based on the Slovin formula, which was used to determine a representative sample size from a larger population. The sample criteria in this study were 10%, with a total of 62 employees participating. The results of hypothesis testing using the t-test (partial) showed that 1) Service quality (X1) had a significant influence on purchasing decisions. This can be seen from the significant value of 0.000 which is smaller than 0.05, there is a partial influence of the Price variable (X2) on Purchasing Decisions, with a significant value of 0.011 which is smaller than 0.05, there is a partial influence of the Promotion variable (X3) on Purchasing Decisions with a significant value of 0.001 which is smaller than 0.05, and 4) the results of the F test (simultaneous) show a simultaneous influence between the independent variables, namely Service Quality, Price, and Promotion on the dependent variable Purchasing Decisions, with a significant value of 0.000 which is smaller than 0.005. So, it can be concluded that overall, there is a significant influence between Service Quality, Price, and Promotion on Purchasing Decisions.
