Education is an important factor in the development of science and the technology. Quality of service is an important element in the institution of education for the quality service of education that will produce high-quality graduates as well. The importance of service quality makes it a part of the Higher Education Quality Standards. Cadets Satisfaction to services is a benchmark to find out the quality of service at Medan Aviation Polytechnic. This research aims to determine the level of Cadets satisfaction to Medan Aviation Polytechnic service towards learning management standard services and standards for infrastructure facilities. The results of the study will be used as references in developing quality standards of Medan Aviation Polytechnic. The method used was Quality Function Deployment (QFD) method, with a total sample of 44 people. Analysis of the data is done with test validity, reliability, planning matrices and matrix House of Quality (HOQ). Analysis results shows the level of cadets satisfaction highest is the dimension Realibility to value the satisfaction of 4.01 followed by the dimensions of Assurance with the value of the satisfaction of 3.98, then the dimension Empaty to value the satisfaction of 3.97 and then at Responsivness dimension with satisfaction value 3.95 and the last is Tangibility dimension with satisfaction value 3.92.

A charge controller is needed not only to improve the efficiency of the caddy cars but also to protect the storage batteries. The main function of a charge controller in Candy Cars is to charge the battery without permitting overcharge and deep discharge as an alternative power source. The study aimed to study and monitor a device that will obtain a controlled power supply. The results of the study obtained the design of voltage pulse generator has yielded a significant result, namely the maximum voltage V max pulse battery is approximately 3.08 % and the current on a step up/down module is 12.5 %

Learning the PID control system in the Control System courses in universities is mostly still using trial and error analysis methods with manual calculations. This kind of learning method has a weakness that requires a long time and has a high level of difficulty. To further enhance students’ understanding in the material of the control system, computer-aided learning media can be used. Matlab is one software that is very helpful for students’ understanding in learning to see responses of various combinations of parameters with different input variations. From the results of classroom action research, there were significant results in improving students’ understanding in the control system course, especially the PID control action material.
