This research is aimed at developing a supplementary reading material to fulfill students’ need in learning reading towards multimedia study program at vocational secondary school. The design of this research is Research and Development (R&D) which is proposed by Borg and Gall. This research was oriented to the product development and it was conducted in two main stages; (1) exploration stage and (2) product development stage. The exploration stage includes (1) literature review, (2) field study, and (3) need analysis. Meanwhile, the product development stage describes (1) prototype development, (2) experts’ judgement, and (3) try out. This research was conducted at SMK Syubbanul Wathon Magelang. There were an English teacher, two material experts, and students involved in this research. The data of the exploration stage were obtained through observation, interview, questionnaire distribution, and document analysis. Exploration stage was done to know the quality of the existing English textbook used at SMK Syubbanul Wathon Magelang and the students’ need towards reading material. The findings show that the existing textbook used to teach reading contains general English material and it is less specific to be used for the students of multimedia study program. Therefore, it implies that there should be a supplementary reading material developed in regard to provide the teacher and to provide the students’ specific need in learning reading. The supplementary reading material was developed by considering some aspects. It contains theoretical theories of English in vocational secondary schools, ESP, CBI, reading, material development, and material evaluation. Then, it was evaluated and reviewed through the experts’ judgement and tried out in class Jadda 3 to make the material feasible. Through observation, questionnaire distribution, and FGD, the prototype was revised to be the final product which is feasible for the English teachers to teach, for the students to study, and to develop all indicators of reading skill since the supplementary reading material provides (a) sufficient reading material; (b) interesting reading material; (c) multimedia-related themes; and (d) comprehension reading material.
