Analisis Model Matematika PLSQ Jumlah Perokok

Smoking is a habit that is favored by some people, but smoking causes health, economic, social and environmental burdens not only for smokers but also for others. This study aims to determine the mathematical model of the number of smokers, analysis of the equilibrium point of the PLSQ mathematical model of the number of smokers and a simulation of the mathematical model of the PLSQ of the number of smokers. In this study, the researcher assumed that the current smoker had a death rate caused by smoking and that the former smoker after he recovered, would not return to smoking. The results obtained are the PLSQ mathematical model of the number of smokers which produces 1 (one) smoke-free equilibrium point and 1 (one) smoker endemic point from the model. The stability analysis of the model was carried out using the Routh-Hurwitz Criteria to identify the characteristics of the eigenvalues. From the results of the stability analysis, it was found that the smoker-free equilibrium point E0 and the smokers endemic equilibrium point E1 were stable if the condition for the relationship between parameters were met. At the end of the study, a simulation model was given using the Maple applicatio

ST HALIJA, 2023. "The influence of brand ambassadors and TikTok social media marketing on the decision to purchase Scarlett Whitening among Management Study Program students" Thesis of the Management Study Program, Faculty of Economics and Business, Makassar State University. Supervised by Mrs. Hety Budiyanti and Mr. M. Ilham Wardhana Haeruddin.This research aims to determine the influence of brand ambassadors and TikTok social media marketing on purchasing decisions for Scarlett Whitening. The variables studied are brand ambassador and social media marketing as independent variables and purchasing decisions as the dependent variable. The population in this study were active students of the Management Study Program at Makassar State University with a sample using purposive sampling of 100 people. This research is quantitative research which was tested using the multiple linear regression method via SPSS 23.The results of this research show that brand ambassadors partially have a positive effect of 0.115 but are not significant on purchasing decisions with a significance value of 0.229 > 0.05, social media marketing partially has a positive effect of 0.765 and is significant on purchasing decisions with a significance value of 0.000 < 0.05. Simultaneously, brand ambassadors and TikTok social media marketing influence purchasing decisions with a significance value of 0.000 < 0.05
