This study originated from a preliminary study at Vocational High School 5 Padang which found a number of facts which concluded that Installation Learning was not yet optimally measured by validation, effectiveness and practicality. This study uses Research and Development (R & D) with the procedure Borg and Gall which aims to create student Guide Book for Contextual Project Based Learning. Qualitative data was collected through observation and interviews, while quantitative data was collected through questionnaires, both data collection tools were validated by experts in FGD (Focus Group Discussion) attended by promoters, professors and senior lecturers of the Postgraduate Program of the Faculty of Engineering on Vocational Field Representation. Research, Development and Optional Refraction, from the FGD obtained research data collection instruments, a set of experiments was carried out to test whether the developed Student Guide Book was valid, effective and practical in the learning of electric lighting installations. A number of students were included in this study with an experimental class and a control class formed. In the experimental class the treatment was given using the student Guide Book of Contextual Project Based Learning while in the control class it was not, with the conclusion that using CPjBL the learning outcomes were superior to conventional ones. The learning outcomes of the two classes were compared with the T-test, the results of data processing showed that there were significant differences between the experimental class and the control class. Based on the results of T-test data processing, it is concluded that students with the treatment of student Guide Book of Contextual Project Based Learning in Learning of Electric lighting Installation is better than the control class that is not given the treatment. The implications of this study need to be an alternative development of learning in Installation subjects in electric lighting and renewal in the student manual, then in improving Installation learning in electric lighting and other lessons, innovation in learning is needed, so the CPjBL student manual is more practical than the conventional one. © 2019, International Journal of Scientific and Technology Research.
