Year after year, the global human population grows while agricultural land is shrinking. The loss of agricultural land is made worse by the depletion of natural resources and the emergence of unanticipated environmental crisis problems like global warming, salinization, and flooding. Due to this situation, food security has become the top priority for all countries in the world. Therefore, smarter, better, and more effective approaches are required to solve the issues posed by the challenges of decreasing agricultural land, one of which is the use of the Internet of Things for agriculture. This essay aims to examine the current situation of IoT adoption in Indonesian agriculture and to put forward and develop strategies for increasing IoT adoption in Indonesian agriculture. The method used in this study is a qualitative approach based on Rogers’ diffusion theory and data were obtained through a literature review. There are five attributes to be considered in increasing the adoption of IoT in agriculture. The innovation attributes are relative advantage compatibility, complexity, trialability, and observability. Optimizing the millennial generation as early adopters is one option for increasing agricultural technology adoption. However, special efforts are required to increase the participation of the millennial generation in government policy agriculture. One of them is to provide adequate infrastructure to support the creativity of the millennial generation.
