This research has the purpose to know the student's learning outcome in Buffer Solution by implementing Project Based Learning model integrated with Lesson Study. Besides that, the purpose is to know the student's cognitive aspect improvement in learning buffer solution with Project Learning model with Lesson Study compared with conventional model. The instrument test had been standardized by expert validator and empiric validity process. The result data showed that student's achievement taught by project based learning with lesson study (0.69 ± 0.11) gave higher significance different compared with student's achievement taught by conventional model (0.41 ± 0.08). The statement supported by the result of hypothesis testing is tcount(16.86)>ttable (1.68). Cognitive aspect which highest improved is C3 (Application) with high score. © 2018 Author(s).
