Processed noodle products are businesses engaged in the culinary field, namely food made from various ingredients, with the main ingredients of tapioca flour and wheat flour. only the basic ingredients are different. As for complementary ingredients such as sauces and spices, it becomes a problem if one of these ingredients is not met, then production in the noodle business will be hampered.

Based on the study findings, the celebrity endorser variable is statistically significant (p < 0.05) with a t-value of 2.993 > 0.05. With a sig value of 0.015 < 0.05 and a computed t value of 2.483 > t table 1.985, the advertising attractiveness variable is statistically significant (t table 1.985). The findings indicate that the significance level is less than 0.05, with a F value of 26,720, which is more than the number in the F table, which is 3.09.
