The aim of this study was to clarify the effect of learning strategies namely plasma cluster multiple intelligences based on learning achievement of cognitive. The study design used was quasi experiment performed using nonequivalent draft pretest-posttest control group design. Two groups of samples formed in this research were student grade XI Biology class 1 as the experimental class, and student of Biology class 2 as the control class. The instrument used in this study was the observation sheet implementation of learning, which is useful to know the feasibility of learning experimental class and control classand multiple intelligences questionnaire used to identify the dominant intelligence on each student. Data was collected through a pretest and posttest. Data analysis was performed with descriptive analysis, while anacova test was performed in order to test the hypothesis; further the test of Least Significant Difference (LSD) is performed. The calculation was assisted with SPSS 18 for Windows. Findings of the research showed that: the learning of plasma cluster multiple intelligences based is influences on the learning achievement of cognitive. Meanwhile, there is an increased learning achievement of cognitive of students being treated with learning strategy of plasma cluster based multiple intelligences by 50.00% higher than the conventional learning strategy by 23.01%. Related to this conclusion, the researcher suggests that teachers would use plasma cluster with multiple intelligences based consistently because it has proven successful to improve learning achievement of cognitive.
