The inquiry learning strategy is very practical for a pandemic era, has provided opportunities for students to access all digital learning sources, including accessing literature book learning resources. Literature books on Environmental and Natural Resource Economics (ENRE) have played an important role in shaping students' insights, attitudes and behavioral tendencies. Learning in the new era, apart from being colored by conventional (face-to-face) methods, has also been firmly followed by a new model of online learning (digital learning). Lecturers and students are required to adapt to new developments in online learning. The need for online learning has also demanded the provision of online infrastructure facilities. The implementation has also been felt by educators and students to be more flexible both in place and time, especially in accessing information.
