Theory of planned behavior to analyze students’ intentions in consuming tap water

Increased consumption of bottled water has a negative impact on the environment due to plastic waste. This study intends to assess the perceptions of Indonesian students toward tap water. This cross-sectional survey was conducted online using an online questionnaire. From 1,034 undergraduate students, our findings revealed that Indonesian students had a relatively low rate of bottled water consumption. Employing the framework of the theory of planned behavior, all factors were recognized as significant factors driving tap water consumption. Students who reported drinking two or fewer bottles of water per week perceive that tap water is safe and clean for consumption is practical, and has almost the same color, taste, and smell as bottled water. Students concede that consuming tap water is a habit and consider this action necessary to preserve the environment. As observed from demographic characteristics, students’ fields of study affect the choice of drinking water. This study has contributed to uncovering the identified factors that determine the habits of students consuming tap water. Apart from the importance of environmental education, increasing the availability of ready-to-drink tap water facilities and disseminating information regarding the benefits and safety of consuming this water are also important factors in reducing the use of bottled water.
