<![CDATA[The purpose of this research are : (1) to improve student?s activity by applying Valve Mechanism of Internal Combustion Engine Trainerfor basic automotive competence at class X TO-D SMK Bhinneka Karya Surakarta in 2013/2014 Academic Year, (2) to improve student?s achievement by applying Valve Mechanism of Internal Combustion Engine Trainer for basic automotive competence at class X TO-D SMK Bhinneka Karya Surakarta in 2013/2014 academic year. This research was Classroom Action Research. The subject was class X TO-D SMK Bhinneka Karya Surakarta in 2013/2014 academic year which consist of 27 student?s. This research was applied to teach basic automotive competence sub-competence valve mechanism. This research was conducted in two cycles. In every cycle, there were four stages: (1) planning, (2) action, (3) observation, and (4) reflection. Data was taken using observation sheets, interviews, test, and documentation. The data from the observation was analyzed to describe student?s and teacher activity during the learning process. The result of this research showed that by applying Valve Mechanism of Internal Combustion Engine Trainer can improve student?s activity and achievement. In cycle I percentage student?s activity (61,33%). In cycle II increased to (79,55%). Student?s achievement in pre-cycle (73,33%), in cycle I (80%) and cycle II (86,66%). Student?s average score in pre-cycle (63,63), cycle I (67,17) and cycle II (78,9). The conclusion of this research is by applying Valve Mechanism of Internal Combustion Engine Trainermethod improve student?s activity and achievement in basic automotive competence sub-competence valve mechanism at class X TO-D SMK Bhinneka Karya Surakarta in 2013/2014 academic year. ]]>
