This research is a qualitative descriptive study using secondary data as the main data. Data were collected through literature studies from the results of previous research in Sumbermanjing Wetan District. The results showed that Sumbermanjing Wetan had the potential to be used as a natural laboratory in the context of geography learning. This is supported by physical conditions in the form of diverse landscape features, quite complex social and cultural conditions. This potential includes the geological and geomorphological conditions of Sumbermanjing Wetan, the geodiversity and biodiversity of Sempu Island, social and cultural conditions, disasters, and tourism. In addition, the existence of natural resources in the area can also be used as one of the studies in fieldwork. Fieldwork-based learning can increase the skills of students in making observations, identifying, experimental, doing teamwork, and applying the use of technology. Geography learning topics at Sumbermanjing Wetan include physical, social, tourism, disaster, environmental, and other areas of geography. Indeed, implementing fieldwork needs to be independent, especially in managing data. In addition, fieldwork-based learning will continue to develop in line with the convenience of technology and increasingly advanced research studies with challenges faced including security, finance, health and safety, access to the field, and damage to the surrounding area used for fieldwork due to sampling exaggerated.
