People essentially have known the risks of smoking and its consequences. However, some Indonesian people, including those in Cikarang Utara District, Bekasi, Jawa Barat, and its surrounding areas, still practice it. In terms of health, it is hoped that smoking habits will decrease from time to time. The Theory of Planned Behavior (TPB) states that Intention is an important factor in determining behavior. Intention means a person's desire or tendency to act a behavior predisposed by attitudes toward behavior, subjective norms, and perceived behavioral control. The purpose of this research was to contribute to reducing smoking through the application of TPB. This research was a quantitative study that applied a purposive sampling technique, involved 518 respondents, and used Structural Equation Modelling (SEM) and Lisrel 8.80 analysis tool. The results indicated that Attitude has no significant effect on Intention to quit smoking, but Subjective Norms and Perceived Behavioral Control significantly contribute to that.
