Since Covid-19 pandemic government requires all educational institution to apply online learning. Therefore, they must be able to use local potential as a learning source as much as possible. One of the local potentials used as a learning source is implementing an inventory of family foodstuffs. This research aimed to determine the type of foodstuff consumed by the biology college student’s families in the Covid-19 pandemic and how to integrate it into the biology learning of biodiversity concept. Data were collected by observing the foodstuffs of 28 biology college students’s families. Every college student recorded the food consumed by his family for two weeks. The data were foodstuffs name, part of foodstuffs consumed and its benefits. Consumed foodstuffs will be sampled, photographed, and identified up to the family level. Foodstuff for every college student’s family were tabulated into Microsoft Excel and collected into class data and then analyzed descriptively. Results showed there were 2 types of foodstuffs consumed by the biology student’s families namely vegetable and animal foodstuff. The most consumed vegetables during the Covid-19 pandemic came from Fabaceae of 15 species and the most consumed animal came from Bovidae of 2 species. Inventory of family foodstuffs during Covid-19 pandemic can be used as a biology learning source of biodiversity. After knowing the taxa of each foodstuff, college students ccould categorize the level of biodiversity. Integrating the environment as a learning source make learning more applicable, varied, interesting, and easier for college students to understand the material being studied.
