Abstract

The utilization of a 3 phase induction motor is increasingly developing, so research on speed regulation in 3 phase induction motors is also increasingly widely studied. This is because the use of 3 phase induction motors in the industry and especially hybrid vehicles are increasingly being developed. But there are some disadvantages of induction motors, one of which is the characteristics of non-linear parameters, especially rotor resistance which has varying values for different operating conditions, so it cannot maintain its speed constantly if there is a change in load. This, of course, can affect the performance of an induction motor. To get a constant speed and better system performance on load changes a controller is needed. This study aims to model direct-quadrate parameters (D-Q) using the Field Oriented Control (FOC) method based on the Proportional-Integral (PI) controller. With the d-q parameter controlled, the induction motor will be more stable, because the d-q parameter determines the stability of the change in torque and flux in the induction motor. Proportional-Integral (PI) control used is a classic control system that is easy because it does not need to look for a mathematical model of the system, but it remains effective because it has a fairly stable system response, by setting the best combination of proportional (Kp) constants and Integrator constants ( Ki). In the results of the implementation, it can be seen that the use of FOC can be used as an approach in terms of setting the speed of the induction motor, and with the use of the PI control can help the output response get better with a shorter response time to reach the reference value.

Abstract

The rice program for poor families or commonly known as Raskin is one of the government's efforts to reduce the burden of expenditure on poor families. The Raskin program is to reduce poverty and maintain the food of economically disadvantaged people so that all parties are expected to participate in the success of this program so that it can be implemented properly and is beneficial to the community. In general, the problems that occur in the assistance of Poor Rice assistance are still not optimal, because at the time of selection of poor rice recipients there is no system that supports so that during the selection process still using estimates only and there is no calculation at the time of selection of poor rice recipients. So that few or many people sometimes protest because people are supposed to get help but they don't get the assistance, and vice versa. The purpose of this study is to help the committee to receive poor rice assistance in selecting people who are entitled to receive assistance, especially in the district of Banawa. The research method used is the software development method using the prototype method and decision-making method using the AHP (Analytical Hierarchy Process) method. Based on the results of testing conducted with the black box technique, the results show that the decision support system for receiving poor rice assistance can help the sub-district, especially the committee in selecting poor rice aid recipients, by comparing the criteria for each alternative and showing the value the highest of alternatives means that the alternative is the main choice for receiving poor rice assistance.
