Entering the era of the industrial revolution 4.0, the order of life refers to the world of the digital industry, as well as the fields of Science and the Environment. The industrial revolution 4.0 requires each individual to run fast to develop literacy skills in technology, data and human resources. These three things become the basic capital in developing various self-competencies for each individual. The development and progress of Science and the Environment today cannot be separated from the mastery of these three literacies. The development of Science and the Environment that is not balanced with the foundation of the nation's fundamental foundation, will in fact contribute more to negative than positive influences. Misuse of Science and the Environment will threaten the existence of human life in the future. Therefore, weapons are needed to ward off various negative possibilities for the development of Science and the environment, one of which is Pancasila. Pancasila powers are not only limited to being the basis of the state, guidelines for life, and unifying the Indonesian nation, but also as a guiding star in all aspects of life, including the development of Science and the Environment. The basic values contained in Pancasila must serve as basic guidelines in the development of Science and the Environment. Pancasila is used as the basis for the development of Science and the Environment and is expected to have a broad impact on the benefit of the life of the Indonesian nation. Science and the Environment may develop and advance, but must be balanced with maintaining and implementing the noble values of the nation's ideology in all aspects of the life of the nation and state.
