Food waste is a global problem that affects food safety and the sustainability of the food supply chain. Unfortunately, food waste is still a big problem for Indonesia. Regarding Bappenas, from 2000 to 2019, Indonesia disposed of 23 to 48 million tons of food waste annually, equivalent to 115 to 184 kilograms per capita per year. In response to this issue, in this study, we try to see how people’s attitudes toward food waste will contribute to raising their intentions and actions to cut down on food waste. This study aimed to examine the impact of mindset on Indonesians’ desire to and actions to reduce food waste. The study used a convenience sampling technique, with a total sample of 231. Respondents are Generation X, who are currently 41 to 52 years old. Data was gathered from March to May 2022. The study’s results prove that attitude positively and significantly affects intention and behavior to cut down on food waste. Additionally, the impact of the intention to reduce food waste also emerged as a key factor. Limitation: This study only looks at how attitudes affect Generation Gen X’ intentions and behavior to prevent food waste.. The paper does not include Baby Boomers, Generation Y, and Generation Z in the analysis. Future research and publications can consist of or analyze the impact of attitude on the intention and behaviour of Gen Y or Gen Z members to reduce food waste.
