Abstract

Power of energy generated from station is the some all the phase. The use of electricity as well as efforts to satisfy customers or consumers of electricity by optimizing the distribution network. By evaluating the distribution network of PT. PLN with the ODK (Open Data Kit) collect method will make it easier to take field samples, find out the long distance of the transformer point by making an arcgis simulation distribution map. After all the data is obtained then to find the voltage drop can be done by analyzing the length of the stretch, the power of the transformer so that it will be known what percentage of voltage drop in the location farthest from the power center.

Abstract

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.

Abstract

Flyback Converter is an electronic circuit that can increase the output voltage value, the voltage value can be adjusted by changing the value of the duty cycle. This Flyback Converter will be controlled by the Pulse Width Modulation method as the output voltage setting and this research is equipped with a feedback function as monitoring and control of Input Pulse Width Modulation. This designed flyback converter aims to provide an isolated power supply as a power source for Brushless Direct Current Motor drivers, and this research was conducted to analyze how much power the flyback converter can produce to be able to supply Brushless Direct Current Motor drivers. The results of the analysis obtained in the research Design of flyback converter for power supply of BLDC (Brushless Direct Current) motor driver that is flyback converter is given an input voltage of 31 VDC and output voltage of 15 VDC, rheostat load with a capacity of 39 Ohm, a frequency of 31 KHz in the form of a box wave duty cycle reaches 70%. Flyback converter designed to produce maximum power of 49.6 watts on 70% duty cycle testing.

Abstract

The 3 phase induction motor in its use is increasingly growing, so research on the speed regulation of the 3 phase induction motor is also increasingly being studied. This is because the use of 3 phase induction motors in industry and especially hybrid vehicles is 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 / controller is needed. This study aims to model the parameters used in Direct Field Oriented Control (DFOC) using Matlab SIMULINK. With the controlled dq parameter, the induction motor will be more stable, because the dq parameter determines the stability of the changes in torque and flux in the induction motor. In the results of implementation, it can be seen that the use of DFOC can be used as an approach in the speed regulation of the induction motor. and with the use of PI controls it can help the output response get better with a shorter response time to reach the reference value.

Abstract

Almost people in Indonesia ever seen quiz who wants to be millionaire. That quiz is sometimes using a polling method to get the right answer. Audience at studio must help a quiz’s participant by using keypad to get a right answer. Audience must push the button of keypad where there is choice of answers. After that the answer will be display in a bar graph of percent. Thiscalled electronic polling system. With the aim of the research is to design and build a polling system with 6 slave-based serialRS-485, USB and microcontroller RISC and design and build a control system based serial RS-485, USB and microcontroller RISC efficient. The method used in this research is to study the reference, namely collecting materials that can be used as a reference, observation and study references required, inventory problems and needs in the design and manufacture, designand manufacture of hardware, software design and manufacturing, and perform testing. RS-485 is standard for communication with very long cable. This standard can use cable almost 1,2 Km long. RS-485 is very unique, this standard using master slave method. So only the master can control slave. Slave is using a microcontroller to manage data. AVR ATtiny2313 is a goodmicrocontroller for slave. This is microcontroller very small and very fast. Base from design, implementation and test result indication implement of RS-485 at polling system can be handle of case distance between master and slave. Beside that not only one slave can be connected to master

Abstract

The rapid development of the world of technology that covers almost all sides of life has encouraged innovation and human creation to make various tools with automatic work systems. Giving fluids using intravenous fluids is one way to enter fluids intravenously to meet the needs of fluids, electrolytes, drug administration, and feeding. The process of replacing intravenous fluids that has reached the minimum replacement limit must be carried out promptly and quickly, so that there will be no delay in changing intravenous fluids which will result in unstable pressure on the infusion set which will result in blood clots. infusion set which will result in blood clots.In its testing, this tool can display information on the total number of intravenous fluid drops, and the condition of the remaining infusion fluid level on the LCD, as well as an additional display of the number of intravenous fluid drops per minute on theapplications client PC and / or smartphone. Adjusting the position of the mini servo of the infusion tap, can be adjusted when the appliance is not or not connected to the client. The sensor optocoupler used can also detect every drop of intravenous fluid. The reading of the sensor optocoupler used can experience an error by a difference of 100% if the dripping of the intravenous fluid is too slow. This is caused by the drip that is read twice by the sensor because one drop of intravenous fluid is read again after more than 50 milli second.

Abstract

Sun is one of the new renewable energy sources that can be used as a source of electrical energy that is available on the earth. But the sun in nature has a light intensity that varies greatly with each time and place. This issue can be overcome by using the Modification Sepic Converter tool with a fuzzy method to produce a stable electrical voltage so that it becomes usable electrical energy. This tool uses a series of converters connected to photovoltaics. The tool also uses a voltage sensor as feedback for the Fuzzy method to maintain a voltage of 21-23VDC to 48VDC.
