To determine the influence of advertising, personal sales, and public relations on purchase decisions, multiple linear regression tests were performed. The results of the research obtained by advertising have a positive and significant effect on purchase decisions. This shows that the ads made by the committee affect the interest of potential consumers, which ultimately drives purchase decisions. Meanwhile, personal sales have a positive but not significant effect on purchasing decisions. This influence is not strong enough to significantly influence consumer decisions in purchasing decisions.
