The Dissemination of Electric Control Installation Based on Microcontroller Through Digital Application in The Vocational School Environmental

SMKN 1 Riau creates an electric control installation device based on a microcontroller through digital application. But the vocational school has difficulty in socialization this innovation. This study aims to explain how to spread the innovation of microcontroller-based electrical installation control devices through digital media in the internal and external environment of SMKN 1 Kepulauan Riau. The theory used to help explain the process of spreading innovation is innovation diffusion through four elements, namely innovation, time, media, and social systems. in addition, this study compares how the process of diffusion of these innovations through conventional means. the method that will be used is qualitative with data collection techniques, include conducting interviews with actors who play a role in spreading the innovation of the electrical installation control device. the results showed that the innovation of SMKN 1 Kepulauan Riau was in the form of electrical installation controllers such as garden lights, water pumps and other industrial installations. teaching factory and training is a way of socializing to the microenvironment while online media is used to disseminate innovation information to the macro environment. the preparation process was carried out for three months.
