Induction Motor in Electrical drive system at a accelleration speed for example in electric cars have a hard speed setting is set on a wide range, causing an inconvenience for motorists and a fast response is required any change of speed. It is necessary for good system performance in control motor speed and torque at low speed or fast speed response, which is operated by Indirect Field Oriented Control (IFOC). Speed control on IFOC methods should be better to improving the performance of rapid response in the induction motor. In this paper presented a method of incorporation of Fuzzy Logic Controller and Backstepping (Fuzzy-Backstepping) to improve the dynamically response speed and torque in Induction Motor on electric car, so we get smoothness at any speed change and braking as well as maximum torque of induction motor. Test results showed that Fuzzy-Backstepping can increase the response to changes speed in electric car. System testing is done with variations of the reference point setting speed control system, the simulation results of the research showed that the IFOC method is not perfect in terms of induction motor speed regulation if itâs not use speed control. Fuzzy-Backstepping control is needed which can improve the response of output, so that the induction motor has a good performance, small oscillations when start working up to speed reference.Keywords: Fuzzy-Backstepping, IFOC, induction motor

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 theÂ 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.

The need for fish is increasing every year. Because it is increasing every year, fish farming must be increased in line with the use of improved fish farming technology. So that it requires an adequate technological structure and mechanization. Based on this background, the arduino-based floating robot for feeding freshwater pond fish is designed to be able to apply technology that is useful in feeding farmed fish. The arduino based floating robot fish feeding freshwater fish pond using Arduino Mega 2560 as its microcontroller, 4 Sharp 2Y0A21 sensors that function to detect pond walls, RTC functions as a timer so that it can feed fish according to the time set on the tool, LCD functions as the information viewer of the tool, the L298N motor driver controls the DC motor and the servo motor functions as the opening or closing of the food valve on the appliance. In the test, the arduino based floating robot fish feeding freshwater fish pond is able to float in water and can feed fish based on the time available on the tool. The Sharp 2Y0A21 sensor as a pool wall detector has a distance reading in the range of 1 millimeter to 10 centimeter. The robot can avoid the pool wall with a span of 3 - 7 seconds, this is influenced, among others, by surging water, wind, sensor response, and DC motors.

The application of the 3 phase induction motor is increasingly developing, this has led to research on speed regulation of 3 phase induction motors is also growing, because the use in industry and especially in hybrid vehicles is increasingly being developed. However, there are several disadvantages of an induction motor, one of which is the non-linear parameter characteristics, especially the rotor resistance, which varies in value for different operating conditions, so that it cannot maintain its speed constantly when a load changes. Therefore, to get constant speed and better system performance against load changes, a controller is needed. This study aims to implement the vector control method in the 3 phase induction motor speed control application in following the reference speed. In vector modeling, the 3 phase parameters (ia, ib and ic) will be transformed into direct quadrature (dq) parameters where in this parameter the setting of the field size and torque can be adjusted separately. In the implementation results, it can be seen that the use of vector control can be used as an approach in regulating the speed of an induction motor.

The use of three-phase induction motors in the industrial world is increasingly growing, in addition to industry, the transportation department is also increasingly using induction motors with the development of transportation models that use electricity. But testing in the performance of induction motors is still not applied. Only the industrial world is able to set test standards for the performance of induction motors. Performance can be seen by monitoring how the output speed of the induction motor. This study aims to create a system that is able to see the performance of the induction motor output in a graph in real time and continuously. In the implementation results, it can be seen that the monitoring system can display a graph that matches the reading of the speed sensor mounted on the induction motor.

Central Sulawesi, precisely in the city of Palu, is one of the areas that frequently occurs in earthquakes and has high seismicity. The regional geology of the Palu area and its surroundings is dominated by quarterly deposits consisting of fluivatil and alluvium deposits. These natural conditions have several potentials that are detrimental, including the potential for liquidity. (Widyaningrum, 2012). Liquidation is an event that occurs when a soil becomes saturated or loses its ability to support the mass above it because the land changes form into heavy water or becomes liquid. Lack of further knowledge about the faction by the surrounding community causes a lack of vigilance in dealing with the faction. The things that people need to know about potentially liquefaction soils are data on soil moisture, changes in underground temperature, and vibrations that are felt underground when earthquakes occur shortly after liquefaction using a device in the form of an arduino nano-based data recorder. The Design of Arduino Nano Based Likuefaction Data Recording Tool can be used to record and record data on lycufaction disaster events. And is used to make it easier to analyze the potential occurrence of liquefaction in certain regions by utilizing the sensor to measure soil temperature, soil moisture, and vibrations that occur in the soil.

The design of this IoT (Internet of Things)-based post-stroke patient monitoring tool was built to monitor patient progress remotely. Flex sensor hardware was used to retrieve data from every movement of the patient's finger muscle strength, then processed by the NodeMCU ESP32 after that the data will be sent to the web server via the IoT platform using a local wireless network. The results of research on the development of post-stroke patients can be displayed to a web server in the form of a table plot of data values for the index finger, middle finger, and ring finger. The post-stroke patient monitoring system can be accessed on PC and Android devices. The results of the sample test from the device obtained the highest value of 3.26 MMT and the lowest value of 0.2 MMT so that the patient's finger muscle strength was declared unstable and frequent changes in muscle strength.
