Physical Chemistry 5 is a main and diffi cult course for students because of its
relation to microsspic properties and abstract with the result that the visualization is
necessity. Therefore, the appealing learning that can manure the students’ creativeness
and innovation and motivate students to be entrepreneurs is necessity. Such learning is a
learning using chemo-entrepreneurship (CEP) approach. Lesson study activity is potential
in learning community and collaboration development effectively. Therefore, the learning of
Physical Chemistry 5 using CEP approach through lesson study activity is necessity. This
research was aimed to improve the students’ achievement on Physical Chemistry 5 lecture
using CEP approach through lesson study activity. This research was conducted by quasi
experiment method involving students on seventh semester of Chemistry Programme as
subject. Lesson study activity was conducted by three stages i.e. planning, doing, and
refl ecting. The instrument of research included the achievement test, observation sheets,
and questionnaire sheets. The results showed that the achievement of experimental group
was higher than of controlled group. The learning completeness of experimental group was
higher than of controlled group. It was shown that this learning can improve students’ life skill.
