This research is quasi-experimental design with randomized control group, pre-post test. The study population was all students of Class X MAN 2 Pati, while the research sample is Class X-2 as the control group and Class X-3 as the experimental group. Data collection techniques were test and non-test techniques. The analyses used the t-test to determine differences in motivation and achievement. The results show that there is difference in learning motivation after using tapioca waste as a source of learning, indicated by the result of paired samples t-test, value of sig.(2-tailed)α. There is no difference in learning achievement after using tapioca waste as a source of learning, which is indicated by paired sample t-test, the value of sig.(2-tailed)α.
