The purpose of this study was to determine the effect of personal responsibility and
knowledge of energy concepts on students' energy saving behaviour. The research
method used is quantitative research using survey method with exposé facto technique
and 2x2 factorial design. This study involved 402 respondents of Primary School
Teacher Education Program students, Education Faculty, Universitas Muhammadiyah
Jakarta. The results showed that there were differences in the energy-saving behaviour of
students who had strong personal responsibility compared to those who had weak
personal responsibility. This finding proved that students' personal responsibility affects
students' energy-saving behaviour. There is a difference in students' energy-saving
behaviour between groups of students who have high knowledge of energy concepts and
students with low knowledge, but this finding occurs by chance, so its influence can be
ignored at this time. There is an interaction effect between students' personal
responsibility and students' knowledge of energy-saving concepts, but the effect is also
due to chance. The conclusion of this study is that students' energy-saving behaviour is
influenced by personal responsibility without the need to pay attention to the level of
students' knowledge of energy-saving concepts, it is proven that knowledge has a
coincidental influence on students' responsible behaviour. Finally, the implication of the
research findings, the personal responsibility factor should get the main consideration
when talking about students' energy-saving behaviour, especially for the students'
participation in contributing to the achievement of massive energy-saving behaviour.
