The method used is an experimental methd with the Pretest-Posttest Control Group design. The sample of this study was grade 7, as an experimental class and grade 9 as a control class at SMP Negeri 1 Mambi Vector props were tested for feasibility by validators using questionnaires. Student responses were measured using questionnaires. Student responses were measured using questionnaires. Students' understanding of concepts is measured from the results of pretest and posttest scores. The feasibility test results of 98.61% show that the props are very feasible to use. The increase in students' understanding of concepts as measured by student learning outcomes in the experimental class after using resultant force vector props of 0.7 is included in the high category. The response of students' attitudes and interests after using teaching aids received an average percentage of 71.06% included in the high category.A vector diagram showing the phase relationship between voltage and current of the sending end and the receiving end. For long power lines, the procedure is complicated due to the presence of distributed shunt capacity. However, by changing the equation of the long line, this can be done in a relatively practical way. For that purpose, the quantity per unit is used with the receiver end voltage and surge impedance load current taken as the basis. A circle as the seat of the sendend voltage corresponding to the unity of the send-end power factor is also derived from consideration.
