This study aims to produce a prototype of teaching materials in the form of a Scientific-based Student Activity Sheet (LKPD) on the subject of automation of facilities and infrastructure management for class XI odd semester automation and office governance in SMK Ketintang Surabaya in addition to this research aims to determine the feasibility of from experts and students' responses regarding LKPD that have been developed. This type of research was developed using a 4-D development model (Define, Design, Develop, Disseminate) but this study only reached the Develop stage because the aim was limited to knowing the feasibility and response to the developed LKPD. The research subjects were 20 students of class XI OTKP 2 at Ketintang Vocational School in Surabaya. The results of the study showed that the LKPD developed in the subject of Class XI OTKP Automation and Facility Management was included in the very feasible category in terms of material, language and graphic aspects, which obtained a total percentage of 82%.
