The analysis showed that characteristic which have correlation with attitude are level of knowledge (rs = 0,420) and working experience (rs = 0,363). The attitude of the workers had correlation with practice (rs = 0,676). The correlation of the attitude of the workers with practice was increased by the influences of SOP (rs = 0,686) and supervision by manager (rs = 0,909).
