Physics-based learning of local potentials on simple plan materials as a source of learning the art of carving through levers, incline, pulley and wheel pivot, learning that equip knowledge about the potentials become benchmarks and reference in developing Jepara regency. Design research using One Group Pretest-Postest Design.analysis included: normality and homogeneity, t-test hypothesis and gain test. Based on the result of t-test (thitung
