<![CDATA[The purpose of this result is to improve the activity and learning outcomes in the basic competence learning the process of energy conversion machine by applying the demonstration method using a motor fuel model for students of class X TKR 2 Kebumen Vocation High School 2nd semester school year 2015/2016. The procedure of the research is carried out through two cycles, each cycle consisting of four steps, namely: (1) planning, (2) the implementation, (3) observations, and (4) evaluation process with reflection. The results of the empirical research proves that implementation method using demonstation method using a motor fuel model, the liveliness of very active students category increase from the initial condition there are 3 students (8%) become 8 students (13,9%) in cycle I, become 7 students (19,4%) in cycle II, and in cycle III increase to 9 students (25%). The liveliness of active students category increase from the initial conditions there are 16 students (44%) become the 21 students (58,3%) in cycle I, increase to 25 students (69,4%) in cycle II, and from cycle II to cycle III there is no improvements. Yhe number of students who learning comprehensively is 36 students in initial conditions 31% with an average value 65,7 increase in cycle I become 44% with an average value 69,6 increase in cycle become 78% with an average value 74,1. From cycle II to cycle III number of students who learning comprehensively increase to 89% with an average value 76,0.]]>
