The results indicated that the students who were active smokers agreed and disagreed on KBBR, nevertheless there are diferences in attitudes related to compliance with these rules. Students who were active smokers who agreed to KBBR supported and there were students who did not support the KBBR. But students who were active smokers that did not agree to KBBR did not support the implementation of KBBR on campus. Unlike the students who were active smokers, passive smokers students all agreed and supported KBBR in UMY. By that attitude, UMY needs to increase their knowledge and socialization of KBBR to the students, therefore the students are able to increase the positive attitude towards KBBR in order to create a clean and smoke-free campus.</em></p><p><strong><em>Keywords</em></strong><em>:</em><em> </em><em>Attitude</em><em>, </em><em>KBBR,</em><em> </em><em>UMY</em></p>
