ABSTRACT
Hands are the principal carriers of bacterial diseases, therefore very important to know that washing hands
with soap or hand sanitizer is highly effective healthy behaviors to reduce bacteria in the palm. This study
aimed to determine the total number of bacteria between washing hands with soap and hand sanitizer, also
applying the results of these studies as a learning resource in bacteriology. The research design was the true
experiment with pretest-posttest control group research design and laboratory examination. Analysis of data
using paired t-test and independent sample t-test with α = 0.05. The result using paired t-test obtained t
count= 2.48921> t 0.05 (14) = 2.14479 (with liquid soap), obtained t count= 2.32937> t 0.05 (14) = 2.14479
(with hand sanitizer). As for the comparison of the total number of bacteria include washing hands with soap
and hand sanitizer using independent samples t-test obtained results there were differences in the total
number of bacteria include washing hands with liquid soap and hand sanitizer with t count= 2.23755> t
0.05 ( 13) = 2.16037. That results showed hand sanitizer more effective to reduce the number of bacteria
than the liquid soap, that was hand sanitizer 96% and liquid soap by 95%.
